Description

CEBO STATION TO COMBAT AGRICULTURAL PESTS

FIELD OF THE INVENTION

The present invention is related to the means of phytosanitary control of pests in various crops; more specifically it refers to a bait station to combat agricultural pests without making massive sprays of insecticide on crops, thus avoiding the imminent consequences of ecological damage due to soil contamination and death of other non-objective organisms such as bees and beneficial insects.

BACKGROUND OF THE INVENTION

In the agricultural sector, in the area of the production of various quantitative factors, the existence of a diversity of pests that attack specific crops is known, which if not controlled, considerably affect the production and yield, as well as the physical characteristics -chemistry of harvested products.

At present, various methods of pest control are known, such as biological control where other insects that attack pests are used; the quantum control that consists in the application and use of certain agricultural practices whose use has been proven as beneficial in the fight of plagues, some examples of these techniques turn out to be: crop rotation, fertilization and irrigation techniques, planting distances, rest of the land, etc .; The genetic control that consists of using the X-rays to irradiate the insects that cause the pest in order to prevent its reproduction, also in many cases, are used on the plants in order to make them more resistant and immune to the pests; physical, mechanical controls and chemical control are also known.

The chemical control is a technique that consists in the application of some product or substance whose chemical formula is prepared to eliminate the insects that can cause a plague. These products can be harmful to any element of the ecosystem, so their use must be measured and prudential. Crops and the environment can be seriously damaged, including humans when they consume some type of food contaminated by chemical pesticides.

In the chemical control method, the technique is used as land sprays where workers brigades sprinkle the chemicals in the crops. This method has important consequences, since it generates collateral effects such as ecological damage due to soil and air pollution, as well as the death of other non-objective organisms such as bees and beneficial insects, and even harmful effects on human health. The air spray is also used where chemicals are applied using light aircraft, airplanes or the like; This technique has the same disadvantages as land sprays; but it is also more expensive, there is a lower probability of dosing the desired areas since the wind often deflects the applications of chemical products.

Insect monitoring techniques are also known to assess the population level and determine the possibility that they become pests, the level of infestation or simply to measure the population that allows determining the actions to be followed.

Thus, to be able to carry out the monitoring, traps are used, which consist of containers in which a substance is placed that captures, kills or makes insects impossible to leave, and which are available in predetermined strategic areas. Such traps allow population counting by sampling of harmful insects that are potential threats of pests.

In accordance with the Guide for Trapping in Control Programs for Fruit Fly in Large Areas, Issued by the International Atomic Energy Agency, based in VIENNA, 2005, the following types of traps are held:

Jackson trap (TJ), the body of the trap is a delta-shaped object, made with waxed cardboard, the additional parts include: 1) a white or yellow rectangular waxed cardboard insert. The insert is covered with a thin layer of sticky material known as "stickem" (Tanglefoot), which catches the flies once they settle inside the body of the trap; 2) a small polymer tablet where the attractant is placed, and a plastic basket that holds the bar with bait; and 3) a wire hook placed in the upper part of the body of the trap.

McPhail (McP) trap [liquid protein bait]; The conventional McPhail trap (McP) is an invaginated container of transparent and pear-shaped glass. It also consists of a cork stopper that seals the upper part, and a wire hook to hang it from the tree branches.

Multilure trap (MLT) [dry synthetic attractant / liquid protein]; This trap is the new version of the McPhail trap described above, it consists of an invaginated plastic container. For the trap to function properly, it is essential that the top part be kept clean. This trap can be used with liquid proteins (as described in the case of the conventional McPhail glass trap), or with the synthetic dry bait. The dry bait consists of three components that come in small separate flat dispensers. These dispensers are attached to the internal walls of the transparent upper part of the trap, or are hung from the ceiling of the trap by means of a clip. Since conventional McP glass traps are one piece, it is not easy to glue the three dispensers to the glass walls. Open bottom dry trap (OBDT) [dry synthetic attractant]; This dry trap consists of an open-bottom cylinder that can be made of opaque green plastic or wax-coated green cardboard. It has a transparent plastic in the upper part, three holes they are spaced along the circumference of the cylinder, halfway between the two ends, and an open bottom, and used with a sticky insert. This trap is used with the synthetic attractant for female females of the fruit described above, in the areas where the McPhail glass or plastic traps, which are more expensive, cannot be used.

Yellow panel (PA), this is a yellow cardboard trap, rectangular, covered on both sides with a thin layer of stickem glue (Tanglefoot). With this trap paraferomonas (TML, M E and CU E) are used as specific attractants for males. The attractants can be used in liquid form, impregnating a cotton with 2 or 3 ml of the product. As in the case of TJ, when using M E or CU E, an insecticide must be added to prevent flies from escaping. Another way to use it is with the attractant placed in a polymeric controlled-release tablet. In both cases the attractant is placed on the face of the trap. The attractants can also be mixed with the glue (stickem) that covers the cardboard. A wire hook in the upper part allows hanging the trap of the tree branches.

C&C (Cook and Cunn ingham); This trap consists of three removable panels, located approximately 2.5 cm from each other. The two external panels are made of cardboard, 22.8 by 1 3.9 cm, and both are covered with stickem by the external part. The adhesive panel has one or more holes through which air circulates. The trap is used with a central polymeric panel containing the olfactory attractant (usually trimedlure). Polymeric panels can be two sizes: standard size and half panel. The standard panel (15.2 x 15.2 cm) contains 20 grams of TML, while the medium-sized panel (7.6 x 15.2 cm) contains 10 grams. This multi-panel construction provides a significantly larger adhesive surface for catching flies. The unit is fastened with clips and suspended in the treetops with a wire hook.

ChamP trap; This trap is a yellow two-dimensional sticky panel, and is designed to be used with a polymer tablet or panel. The face of the rectangular panel is perforated to allow a high release of the attractant. The outer surface is coated with stickem, and synthetic attractants are used.

Tephri trap, is a McPhail type trap widely used in Europe (eg, on the Mediterranean coast) to monitor populations of the Mediterranean fly. It has a yellow base and a transparent lid, which can be removed to facilitate service. It has entrance holes in the upper part of the yellow base, and an invaginated opening in the bottom.

Steiner trap (TS), it is a transparent horizontal cylinder with two large inlets at the ends. With this trap, specific parapheromones are used to attract TML, ME and CUE males. A wire hook in the upper part of the body allows hanging the trap of the tree branches. As in the case of other dry traps (except sticky traps that use TML), an insecticide must be used to prevent the escape and depredation of captured flies. The traps have the disadvantage of trapping and conserving the specimens for later quantification.

Each trap design has a specific objective, but they all have something in common, they serve to capture different species of fruit flies in order to monitor existing populations and with this information obtain conclusions of the levels of infestation and implement control actions of The plague

The present invention is directed to provide a bait station type device that allows to attract insects harmful to crops, facilitate their entry and the consumption of food with chemical products (poison) that kill the insects after a time of their intake; the insects can leave the station and die later.

Said bait station is not a means to monitor populations of the pest but to combat them.

OBJECTIVES OF THE INVENTION

The main objective of the present invention is to make available a bait station to combat agricultural pests, which solves the need to fight populations of pests without making massive sprays of insecticide on crops, thus avoiding the imminent consequences of ecological damage due to soil contamination. and death of others non-objective organisms such as bees and beneficial insects.

Another objective of the invention is to make said bait station available to combat agricultural pests, which also allows attracting specimens that feed and leave and subsequently die after a few minutes in the open field.

Another objective of the invention is to allow said bait station to combat agricultural pests, which also avoids ecological damage due to soil and air pollution, by avoiding the application of chemical products such as land and air sprays.

A further objective of the invention is to make said bait station available to combat agricultural pests, which also prevents the death of other non-target organisms such as bees and beneficial insects.

Another of the objectives of the invention is to make said bait station available to combat agricultural pests, which also represents an alternative compatible with the ecological production of crops and with intelligent pest management.

Still another objective of the invention is to allow said bait station to combat agricultural pests, which is also considerably more economical and efficient than the chemical control methods of land and air application. A further objective of the invention is to make said bait station available to combat agricultural pests, which is also structurally simple, practical and functional, and which is also easy to handle, assemble and install at the control points.

And all those qualities and objectives that will become apparent when making a general and detailed description of the present invention supported by the illustrated modalities.

BRIEF DESCRIPTION OF THE INVENTION

In order to achieve the objectives, different designs of structures were made that were subjected to multiple tests, structural and functional, mainly assessing their effect in the field; Ia was assessed structural configuration that would allow the desired functionality of manipulation, assembly, placement of the substrate or bait with attractants and control chemicals, ease of access and exit of insects; The effectiveness of attraction, installation and handling in the field, etc. The foregoing implied a considerable investment of economic resources, personnel, equipment, etc.

Based on the above, it was concluded that the bait station to combat agricultural pests should have two assembled modules, a basal module and an upper module, this allows easy service of the same, to solve a first practicality problem of management for both technicians and agricultural producers, as well as the placement and handling of the bait substrate.

Then, different designs were made, the prototype consisted of two modules but with very different dimensions, which had negative technical implications because the size of the upper module served as a condensation hood of the attractants volatile with zero or low attraction efficiency Of pests. In addition, another implication was regarding its limited industrial potential.

Another problem was related to the ability to attract insects to different colors, they were tested from the transparency and different hue of the yellow color, the latter being the one with the greatest attraction for insect pests, that is why the Basal module is this color. Another of the key design points is Ia aerodynamics, the air had to circulate inside the upper module in an efficient way, in order to dissipate the attractant; This was achieved with the incorporation of strategically arranged windows in the upper module.

The Bait Station to Combat Agricultural Pests has the specific function of attracting adult insects in order to feed on the bait placed in the basal module, this bait once ingested causes the pest insect to die. Said station is not a means to monitor populations of the pest but to combat them. Because the bait-insecticide inside the trap does not come into contact with the crop, it represents an alternative compatible with the ecological production of crops and with the intelligent management of pests.
