Description

Flying insects with light pattern

brightness of at least 50 lux.

  The present invention relates to a light trap that can attract flying insects and immobilize insects in a trap casing. The trap uses a casing containing an insect-attracting light. The housing and associated internal reflective surfaces provide a multidirectional light pattern on a flat mounting surface, such as a wall or ceiling. The pattern may contain one, two, three or more light displays, overlapping or not, generally positioned in arbitrary directions. In a bidirectional trap, the direction of light from the displays on the planar mounting surface is positioned at an angle of 180. Such a configuration can increase catch rates. In other traps having three or more light displays, the light patterns may be positioned at regular intervals or arbitrarily positioned. The invention also relates to flying insect traps using pattern illumination.

  substantially surrounding the trap to attract flying insects.

  A number of flying insect traps using attractive light sources have been proposed in the prior art. Insect-O-Cutor fly traps made by I-O-C use an exposed bulb with a high-voltage electrocution system. Pickens and Thimijan exhibit exposed UV-emitting light sources and electrified grids to trap and electrocute flying insects. Another trap system typically uses ultraviolet light sources exposed frontally or horizontally to attract insects into the

  trap. In the trap, insects land on an electric grid at the back of the case.

  The grid delivers a low voltage pulse that lands the insects on a nontoxic adhesive trap plate. The captured insects can then be removed with the detachable adhesive sheet. Similarly, Grothaus et al., U.S. Patent No. 4,696,126, discloses an exposed bulb adhesive trap. Lazeroni, Sr. et al., US Patent N

  325,954, has an exposed bulb trap facing globally forward.

  Aiello et al., US Pat. No. 4,959,923, is similar to that of Lazzeroni, Sr. et al., US Pat. No. 1,325,954, by the use of a source of ultraviolet light and electrical pulses to stun insects and an adhesive trap. Similarly, Gilbert's insect light traps use exposed bulbs and generally open entrance spaces to trap flies. These traps attract pests in front of the trap by using light directed into a room from the trap. Hollingsworth and Hartstack, Jr. present data regarding the effectiveness of

  different components of fly traps with exposed bulb.

  Larkin, US Patent No. 4,949,501 and ARP Venus Flylite have an attractive light source. The light source and its housing are hinged to wall fixing means so that the unit can be used in vertical mode, wherein the light source is parallel to the vertical surface and is placed at an angle to the horizontal surface perpendicular to a vertical surface. In this so-called "invisible" mode, used during the day, the trap is designed to keep the functional components of the fly trap away from detection. The fly trap may be placed in "turbo" mode, in which the light source and the housing are perpendicular to the vertical surface and horizontal to the ground (or at an angle greater than 90 relative to the vertical surface), in order to expose the light directly to the view in the installation site, which is said to increase the number

attracted insects.

  White, U.S. Patent No. 4,876,822, discloses a flying insect unit comprising a rectangular housing enclosing a light source and an adhesive trapping surface. The housing members are either parallel or perpendicular to the vertical mounting surface. Nelson et al. U.S. Patent No. 5,365,690 discloses a

  housing forming a pattern of light attracting insects to a mounting surface.

  We have developed an improved flying insect trap that uses an improved and surprisingly effective display of reflected and reflected light directed in at least two directions overlapping or not. The display can project attractive light patterns onto a flat mounting surface such as a wall or ceiling that is directed

  in opposite directions to the trap.

  In addition, the invention may involve forming a display of three light patterns on the flat surface. Each pattern is directed to form patterns that do not overlap with a spacing of 120. In addition, the light trap of the invention may contain four distinct patterns formed on the flat surface at intervals of about 90 around the housing. In addition, this trap can project five, six, seven distinct patterns or more from a central housing to form a bright pattern.

attracting on a flat surface.

  Another embodiment of the flying insect trap according to the present invention

  The invention is a trap that forms a continuous pattern of light around a central housing.

  The shape of any luminous pattern of any of the discussed embodiments may vary depending on the source of the insect-attracting light, the position of the trap and the light source, the size of the trap, the shape and reflectivity of the internal components of the housing and the geometry of the substantially planar mounting surface. Depending on the design features of the housing and any reflective surface within the housing, the shape of the insect-attracting light pattern on the wall may be configured in any arbitrarily chosen pattern such as a generally rectangular pattern, a overall "fan" pattern, generally oval or elliptical patterns, or in a substantially circular pattern. When a housing that forms a continuous pattern of light around the housing is used, the housing may be circular, oval, triangular, square, pentagonal, hexagonal, etc., the continuous pattern of light may be formed using a light source substantially circular such as a circular fluorescent tube or may be formed by a plurality of light sources which form the substantially continuous display using overlapping light patterns. We have discovered that light, to be attractive in most areas and installation sites, must have an illumination level that is at least about 50 lux (5 foot candles) within the attractive pattern formed on the wall. We have discovered that the illumination achieved by the fly traps of the present invention involves a housing which is configured to ensure that the bulk of the radiant energy emitted by the attractive light source falls on the mounting surface. substantially flat (usually a ceiling or wall surface) associated with the trap. In the vicinity of the trap, illumination can be relatively high, about 200 to 500 lux (ie 20 to 50 foot candles) of radiated light energy or more with typical fluorescent tube sources. As the distance between a measuring point and the fly trap increases, the illumination decreases so that at some point remote from the trap the illumination is less than about 50 lux (5 foot candles). Generally, the attractive light patterns may be a regular shape such as a circular pattern, a square pattern or may be arbitrarily geometrical or generally triangular, rectangular, oval, ellipsoidal, fan shaped or circular, etc. We have also discovered that it is important that the immobilization surface of insects be

  inside the case and associated with the light attracting insects.

  Pests tend to land on the vertical mounting surface or fly directly into the trap. When the insects are walking or flying in the trap, they tend to fly towards the insect-attracting light and, once in the trap, flying or moving at random, they will most likely be immobilized on the immobilizing surface. 'insects. The free or mounted internal reflective surfaces of the housing, reflective surfaces, and other aspects of the trap add light reflected to the radiated light to form the attractive light patterns on the substantially planar mounting surface. We have found that the open entrance passage to gain access to the insect immobilization means in the trap adjacent to the light pattern improves capture rates. The flying insect traps of the present invention are typically mounted on a vertical plane such as a wall surface or a substantially planar ceiling surface. The flying insect trap shall be mounted in such a way that all or a substantial part of the reflected light and the radiated light fall on the mounting surface to form a luminous pattern

attractive.

  In the present application, the term "multidirectional" flying insect trap may include both insect traps having two, three,

  four or more patterns of trapping discrete flying insects that do not overlap.

  The term "multidirectional" may also include flying insect traps having two, three, four or more discrete but overlapping patterns. As the number of patterns increases, patterns tend to fuse into overlapping patterns and when the insect trap includes a large number of patterns,

  patterns merge into a substantially continuous pattern that substantially surrounds the trap.

  For purposes of this application, the term "continuous" indicates that light from the trap is directed in a pattern that illuminates the planar mounting surface (such as a ceiling or wall) in a pattern that substantially surrounds the trap. Such a substantially continuous pattern may include slight shadows due to mounting brackets, street lights, cables or other electrical or mechanical aspects of the housing, the mounting means, the lighting fixture brackets or any other aspect of the invention. In addition, for the purposes of this application, the term "substantially planar" means that the flying insect trap according to the present invention may very well be mounted on a surface. These surfaces may have curved portions such as a pillar or circular or elliptical column. However, as long as it is possible to mount the trap on such a surface and form the multidirectional light pattern, such a surface can be considered substantially flat. For the purpose of this application, when the trap is installed according to certain preferred orientations, the light inside the trap can not

  not be viewed from a normal trap position.

  The term "normal" indicates that the observer's position forms an angle of 90 to the intersection of two lines drawn on the mounting surface intersecting at the

  level of the trap with an angle of 90.

  Figures 1 to 7 each represent an embodiment of the fly trap of the invention. In each figure, the geometry of the trap forms two or more patterns

  of light or a continuous pattern of light surrounding the trap intended to attract insects.

  The figures further show the installation of a light source attracting insects and

  different locations of the immobilizing surface of insects.

  The improved fly traps of the present invention include a housing, an insect attracting light source and at least one fly immobilizing means. The housing may contain two, three, four or more reflective surfaces that ensure that the majority of the light radiated by the insect attracting light source is radiated and reflected to form the attracting light pattern on the substantially planar mounting surface. The display of light in an attractive pattern attracts flies to the fly trap. Flies tend to land on the illuminated pattern, housing or other trap surfaces. The immobilization surface of the insects is positioned to ensure that the flying pests are mostly immobilized in the trap after being attracted to the trap. We have discovered that a portion of the light radiating from the light source is reflected on the inner surface of the housing and any other reflective surfaces disposed in the housing and appears on the planar mounting surface with the directly radiated light. The reflected light and the radiated light form an attractive light pattern on the associated flat surface. The housing directs either two or more distinct patterns of light onto the reflective surface or a bright pattern that substantially surrounds the trap housing. According to a first embodiment of the trap of the invention, the housing can contain an insect-attracting light source and two reflecting surfaces which form patterns of light attracting opposed reflected and radiated insects (separated from 180 on the flat surface) . When using a single light source, the easiest trap to configure is a trap whose attractive light pattern directions are positioned in opposite directions, however the directions of light in the pattern can be at any arbitrary angle and may overlap or form separate patterns. The angle of the directions between the individual lightpaths can be from 10 to 15 or up to 180. The choice of the housing comprising the reflective surfaces and an insect-attracting light source must be made to ensure that the attractive light patterns formed have at least 50 lux energy (5 foot candles) in a pattern. This luminosity or surface light intensity is important for maintaining effective fly capture rates. According to an alternative embodiment, the bidirectional light trap having two attractive light patterns may utilize two or more insect-attracting light sources to ensure that the illumination or surface intensity of the attractive light patterns is sufficient. to obtain effective catch rates. The second embodiment of the invention may include one or more insect-attracting light sources and a housing that cooperates with light to form three distinct patterns of insect-attracting light on the planar mounting surface. The housing may be triangular and may be configured with respect to the insect-attracting light source such that the patterns of light are formed on the wall in patterns that are spaced around the housing at an angle of about 120. The angles between the patterns may be less than 120. In addition, the regular positioning of the light patterns around the trap increases the surface of the attractive light patterns

  and also seems to increase or optimize catch rates.

  According to another embodiment of the present invention, one or more insect-attracting light sources, preferably four sources, are positioned in a housing such that four light patterns attracting insects trained to

  - From the radiated light and the reflected light are positioned around the housing.

  The light patterns are positioned with a separation distance of the pattern directions of 90 around the housing which may take the form of a square or a rectangle. The geometry of this preferred housing embodiment of the invention can provide two, three, four, five or more distinct light patterns arranged around a central housing separated by a regular angle to create attractive light displays. insects having an optimized surface with illumination greater than a power of

lux (5 candles-feet).

  As the number of light areas increases, the patterns of the display may merge into an insect attracting light display arranged substantially continuously around the housing. As a result, an important embodiment of the present invention is a flying insect trap housed in a housing that includes such a circular, oval, ellipsoidal or other type housing that cooperates with an insect-attracting light source that forms an attractive pattern that surrounds the case with a light pattern attracting insects. Depending on the geometry of the case, the shape of the luminous pattern can be chosen arbitrarily by the ordinary craftsman. However, we have discovered that the preferred form of the light pattern is circular, oval, ellipsoidal, and so on. in a regular geometric form in which the

  Luminous pattern has a brightness greater than 50 lux (5 candles-feet).

  The housing can be mounted on a vertical flat surface such as a wall or on a flat horizontal surface such as a ceiling. The trap can be mounted so that a portion of the insect-attracting light falls on both a wall surface and

  a ceiling surface or other common surface in the trap environment.

  The useful light source in the insect-attracting trap of the invention comprises at least one ultraviolet light source. These sources are designed to provide a substantial amount of ultraviolet light but may also have some of the reflected light and the radiated light falling into other parts of the electromagnetic spectrum, other than the ultraviolet portion. Such light sources are usually electrically powered incandescent or fluorescent light sources that can emit a broad spectrum of wavelengths but are primarily optimized for emitting ultraviolet light. For the purpose of the present invention, ultraviolet light comprises electromagnetic radiation having wavelengths between 400 nm and 4 nm, which have been found to attract flying pests. Light sources commonly provide from about 0.5 to about 100 watts of light output, preferably the light provides from about 0.5 to about 75 watts or more. Preferred light sources are fluorescent light sources having sufficient power to form an attractive light pattern having a brightness greater than about 50 lux (5 foot candles). The trap can use a single source or two or more sources arranged horizontally, vertically or diagonally in the housing. The light source may be of linear or curvilinear shape (ie circular or oval or ellipsoidal) and may also be the most recent fluorescent tubes that are screwed into a screw-type incandescent bulb socket. , called compact fluorescent bulbs to screw. These tubes can be used with housings adapted to their geometry

of particular bulb.

  The light source or sources are substantially housed in a housing having a reflective inner surface. In preferred cases, when the housing is mounted in a fly capture environment, the occupants of the environment are not typically exposed to direct light radiation. As a result, the housing substantially surrounds the insect-attracting light source so as to be out of sight of the individuals in the environment while optimizing the size of the attracting light pattern on the planar mounting surface. In addition, the housing, while surrounding the insect-attracting light source, serves as an entryway for flying pests. As a result, the opening must have a sufficient surface area and must not be a barrier to pest entry, nor prevent these pests from being immobilized on the insect trapping surfaces inside. of the trap. The housing can be configured with the light pattern of the trap positioned at any arbitrary angle to the vertical. The housing may be positioned such that the direction of a light pattern from a source on a flat surface has a vertical orientation, or some arbitrary arbitrary angle

  chosen during the installation of the trap.

  The light traps of the present invention form two or more light patterns attracting insects to the vertical mounting surface. Although the patterns can be displayed on the flat surface at regular intervals around the trap, the patterns can be formed on the mounting surface according to virtually any

relative angle.

  The light source is substantially enclosed in a housing having a surface

internal reflective.

  The housing can take virtually any arbitrary shape compatible - with the use of the housing and reflective surfaces to reflect and radiate light onto the mounting surface to attract flying insects. The case can be a regular shape including a triangle, a square, a rectangle, a parallelogram, a circle, an oval, an ellipse, a drop shape, a star shape or can have a shape

irregular or amorphous.

  The housing is commonly made from commonly available structural materials including a filled or uncharged thermoplastic such as polystyrene,

  polyethylene, polypropylene, polyethylene terephthalate (PET polyester), poly (acrylonitrile)

  butadiene-styrene), etc .; metallic materials such as aluminum, magnesium or alloys, steel, stainless steel or other associated ferrous alloys; wood and wood products; reinforced thermoplastics or thermosetting materials; cardboard, cardboard, corrugated cardboard and virtually any other material that can form a casing with sufficient structural integrity for the casing to support installation, bulb replacement, installation and removal of surfaces immobilization of insects, the

  cleaning and other maintenance or routine work.

  The interior of the housing can be highly or at least partially reflective.

  The case can be made of gloss white, white or unbleached material that can reflect incident radiation to form a pattern. These materials may include pigments such as titanium dioxide, calcium carbonate or other white mineral that tends to reflect a significant portion of the incident radiation. In addition, the housing can be painted or covered with reflective materials. A number of highly reflective white paints can be used to reflect substantially all incident ultraviolet radiation. In addition, metal surfaces made from thin sections of metal, metallized polyester, or any other shiny metallic surface can be introduced. Specific examples of these reflective layers are aluminum foil, metallized polyester, glossy white reflective panels containing a substantial proportion of white titanium dioxide pigment, mirrors

  in silver glass or other highly reflective surfaces associated.

  A housing may also contain at least one means for immobilizing insects. For purposes of the present invention, the term "insect immobilization means" covers any device or surface that can prevent flies from emerging from the fly trap after entry. These immobilizing means may comprise pesticides in the form of a pesticide surface, a layer or trap, active and passive mechanical traps, liquid traps in which the flies are embedded, adhesive layers to which the flies stick together, layers of pressure sensitive adhesive, high or low voltage electric grilles or other such means that can trap, immobilize, kill or dismember insect pests. The immobilization means can be installed on the housing, the surface of

  mounting or any other location near the light or attractive light pattern.

  An insect immobilization means preferred for the purposes of the present invention comprises a pressure sensitive adhesive surface. The particularly preferred surface comprises a very tacky pressure sensitive adhesive surface which immobilizes the fly substantially as soon as the fly comes into contact with any part of the surface. The pressure sensitive adhesive surface can be made from various known pressure sensitive adhesive materials which are very tacky to the touch. A

  Known adhesive of this type is the trap adhesive manufactured by The Tangle Company.

  The positioning of the insect immobilization means inside the housing is a design choice. The means can be positioned at virtually any location within the trap available for harmful flying insects. The pests can either fly into the trap or land on the vertical mounting surface or on the housing and can then walk or be carried in the means of immobilizing insects by the operation of the trap. The preferred pressure-sensitive entrapment adhesive may be positioned within the trap on the vertical mounting surface, on the housing, on a trapping surface mounted directly adjacent to the insect-attracting light source or at any another position within the trap near which the flying pests attracted to the pattern formed on the adjacent flat surface. The traps of the invention may include an insect attracting chemical. Such chemicals are typically organic materials that are at least somewhat volatile and are products derived from food sources typical of insects or comprise a pheromone mixture intended for specific insect pests.

the trap environment.

  The insect trap in general or the immobilization surface of insects in particular may also include an effective amount of an insecticide. Various non-volatile insecticides in formulated compositions are known for their effectiveness against flying insects and most can be used. The preferred insecticide for use in the present invention is a nonvolatile formulated insecticidal composition which is adapted to kill harmful insects coming into contact. Such nonvolatile insecticidal compositions are not released into the trap environment. These materials may include insecticidal organophosphate and pyrethroid compositions. These materials may be blended or formulated into the pressure-sensitive adhesive on the insect immobilization surface or may be installed

  separately at a location inside the trap.

  The preferred method of construction of the insect trap according to the present invention involves a geometry of the reflective surface (s) in the trap which forms two, three, four, five or more discrete zones of attractive light, up to a housing which displays a continuous bright pattern around the case. Most prior art references, however, are designed to direct their attractive light into the environment surrounding the light and not by radiating and reflecting light onto a flat mounting surface near the trap. Nelson et al., U.S. Patent No. 5,365,690 discloses a trap that forms a single insect-attracting pattern on a surface

adjacent mural.

  We have proposed an improved geometry of a housing with respect to traps of the prior art such that the attraction of the light pattern produce catch rates higher than the expected rates. By positioning two, three, four, five or more insect-attracting light patterns around a housing to an insect-attracting pattern that surrounds the housing as a whole, substantially improved capture rates can be achieved. The internal geometry of the housing and any inner reflective surface within the housing is mounted on the housing surface and disposed proximal to a light source can be positioned relative to the mounting surface at an angle perpendicular to the surface to ensure that the light pattern formed by the housing contains a substantial amount of light. The insect traps of the present invention may include a screen or shield on the opening of the housing. These grids are configured from iron or plastic screens such that flying pests can enter the trap but the grid or screen does not significantly reduce the amount of patterned light attracting to the wall. For purposes of the present invention, grids and screens having a size large enough to allow the passage of insects may be used, but providing a barrier for larger objects without, however, substantially blocking the reflection or radiation of light from the trap. Such screens or grids can be made from various materials including transparent, translucent or opaque materials. These materials include wire, synthetic or natural fiber yarns, thermoplastic grids, foamed metal screens, and the like. The insect trap of the present invention may be placed on a substantially horizontal flat surface. This surface may be adjacent to a second wall surface, adjacent to a ceiling surface or other internal surface of the fly trap environment. By positioning the fly trap so that the fly trap can display a maximum light area with a brightness greater than 50 lux (5 foot candles) ensures optimal catch rates. This light can be reflected and radiated onto wall surfaces or

  adjacent ceiling without significant reduction in catch rates.

  We have also discovered in our research and development that a color contrast or apparent edge effect where the illumination ends abruptly or falls on a dark color may be attractive to flying pests. Very often, the contrast between a bright portion and a relatively darker portion at a sliced edge may be recognized by flying pests and may be a feature that attracts them. These contrast or edge effects can be produced using contrasting colors or textures for

  Trap training and for trap installation areas.

  When the flying insect trap according to the present invention is installed in an environment of use, the trap may comprise mounting means which may be used to secure the flying insect trap of the invention on a flat surface such as a wall or a ceiling. These mounting means may comprise a mechanical system that can support the weight of the trap and can maintain the orientation of the trap and ensure that the light forms useful attracting patterns on the surface. These traps can be fixed in place using a variety of mounting hardware, such as screws, bolts, nails, fasteners, flanges, etc. or may be temporarily placed in the environment of use by using velcro strips, pressure-sensitive adhesive pieces, urethane or epoxy building adhesives, etc. An important feature of the fly trap mounting means of the invention is a choice of mounting means such that the trap is securely mounted to the wall or ceiling surface.

  for receiving light from the trap to form an attractive light pattern.

  In addition, the wall can be used to deflect the opening of the fly trap. The illuminating or attractive light source may be mounted directly in the housing or may be mounted on the vertical walls or the ceiling surface surrounding the housing. Preferably, the light trap is a one-piece device whose light, reflecting surfaces and insect immobilizing means are fixed inside the housing. However, any part of the attraction system may be mounted on the vertical surface separately from the trap but preferably within the housing. In the case of assembly as a single unit, the insect-attracting light source can be placed in an optimum position relative to the housing and any other additional reflective surfaces to maximize the surface and illumination of the insect. attractive pattern. Similarly, the immobilizing surface can be fixed at any location within the housing. The immobilizing surface is preferably located at a location within the housing where the immobilized pests are hidden from view when viewed from the position of those present in the typical environment. Preferably, the immobilizing surfaces are placed directly opposite the opening of the trap through which light passes to form the attracting surface pattern. When the pests enter by walking or flying into the trap from any arbitrary direction, they may land on the illuminated pattern, on the case, or on any other interior or exterior surface. The immobilizing surface of the insects is placed in the trap so that the typical fly attracted by the luminous pattern enters at a given moment into the trap and is attached to the immobilizing surface. The insect trap housing includes at least one reflective surface that may be associated with the inner surface of the housing. The reflective surface may have different configurations with respect to the insect-attracting light source. The lights can be positioned vertically with respect to the reflecting surface so that the light is efficiently radiated and reflected from the trap onto the mounting surface. The housing designed to be disposed on a vertical or horizontal surface may have different shapes when viewed from outside the trap. The shape of the housing can be chosen arbitrarily while maintaining the reflective internal surfaces of the trap so as to form a two, three, and so on luminous pattern. directions on the adjacent wall surface, while maintaining an arbitrary casing appearance that is generally circular, oval, ellipsoidal, square, rectangular, triangular, hexagonal, etc. The outer surface or the reflective inner surfaces may be flat, curved, angular or may have any shape that does not prevent effective reflection of light on the attracting pattern. The location of the trap on the vertical (wall) surface or on the ceiling is chosen arbitrarily. The location may be in an area where flies appear to be attracted to the surrounding area. As a result, the trap can be mounted near windows, doors or ceiling lamps to which light draws them. In addition, the traps may be placed near organic materials or heat sources which are also attractive to known insects. Typically, the insect traps of the present invention are placed at or above the eye level in the surrounding space. A

  this position is more aesthetic and does not influence catch rates.

  Experimental part Experiment with multiple ultraviolet light motif Context and purpose Ultraviolet light reflected and radiated onto a wall, forming a unique "light pattern", above the top opening of an insect trap containing the ultraviolet light source , attracts flying insects (US Pat. Nos. 5,365,690 and 5,505,017). This experiment determines the effect of multiple "light patterns" formed through upper, side and lower openings on the attraction

  flying insects in an insect trap.

  Method 1) Four Stealth Decora Tm fly traps are placed in two groups in a test "flight chamber" on a vertical mounting surface (white painted wall). A first group comprises four traps, arranged in a square arrangement, with the light patterns at right angles to an adjacent trap. The traps are placed with the light patterns directed away from the center of the arrangement. In a second group with a similar right angle arrangement, the light patterns of all traps are directed to the center of the group. 2) The ultraviolet light source is a 9 watt (Osrqm Dulux S, 9W / 78) lamp in each Stealth Decora trap, for a total of 32 watts for

trap arrangements used.

  3) A single control trap includes a single Stealth Decora trap with

  four 9-watt lamps (total 32 watts).

  4) House flies are released into the "flight chamber" to ensure a density of 0.1 fly per cubic foot and allowed to acclimatize for

two hours, with food.

  ) Control configurations and test layouts are practiced in a completely randomized block design, one on the wall at a time. 6) The capture of flies in half an hour is measured for each configuration, then the configuration is modified to move to the next according to what is planned in the completely randomized block design, and the fly capture in half an hour is measured for this configuration, etc. 7) At least four blocks are tested to obtain at least four

  repetitions for each configuration.

  8) Average and median catch rates per half-hour are determined in order to

  to evaluate the configuration performance.

  Results The capture of flies is surprisingly effective for the first group by

report to the witness.
