CS239144B1 - Insect trap and monitoring - Google Patents

Abstract

The invention relates to a trap for catching and monitoring insects consisting of two roof-like surfaces with different apex angles connected to each other on the sides into the shape of a trap imitating the shape of a sitting wrapper in cross-section, a reinforcing frame to ensure a stable shape, an attractant carrier for luring insects inside the trap, the upper roof-like surface being provided with holes for fixing a wire and a layer of non-drying adhesive being applied to the inner sides of the roof-like surfaces. The invention can be used in forestry

Description

The invention relates to a trap for catching and monitoring insects such as e.g. butterflies and mainly various kinds of envelopes.

In practice, several types of traps are used and used to capture and monitor insects using e.g. pheromones or other attractants. It is known e.g. trap consisting of two opposing, centrally angled plates (approx. 150 angles) made of plastic and connected to each other eg by rings and the like. The disadvantage is the complicated handling, instability of the structural elements lilavely in dependence on climatic conditions i.e. considerable deformation which allows access of small birds, undesirable sticking from non-drying glue and the like.

another of the known traps of similar shape has large air vents which spell its non-selectivity. The Delta roof trap ”is disadvantageous because the shape of its air inlet attracts small birds that get stuck on the adhesive layer inside the trap. The so-called. pipe trap has a massive weight, is bulky mainly when shipments require massive packaging. The problem is the disposal of worn pieces, water leakage, considerable temperature fluctuations inside the trap, catching small birds.

It has been found experimentally that the above-mentioned drawbacks of the known and used traps are overcome by a trap for catching and monitoring insects based on the roof area principle of the invention.

SUMMARY OF THE INVENTION It consists of two roofed flats with different apex angles connected to each other in the shape of a trap imitating the shape of the seat wrapper, a reinforcing frame to provide a stable shape and an attractant carrier inside the trap for attracting insects. One roof surface is provided with holes for fastening the wire and a non-drying adhesive layer is applied on the inside of the roof surfaces.

The advantage of the trap according to the invention lies in its constructional and handling properties (easy handling at work) and

- 2 mainly in its functional properties - higher selectivity of trapping to other traps. Gptimizing the shape, dimensions and side openings reduces the possibility of raiding non-target organisms such as small birds, destroying the possibility and speed of undesirable pollution, overfilling with water, etc. thereby extending the life of the adhesive surface, which has a maximum dimension (400 1000 cm ² ).

The trap according to the invention is shown in the attached drawing.

The trap consists of two roof-shaped surfaces 1, 2 with the difference nym top angle, to each other on the sides connected to the shape of the trap 2 mimicking the sectional shape of a seated coater, the strengthening frame 2 ns ensure a stable shape of the carrier attractant 6 inside the trap 2 ^for attracting insects, wherein the roof surface 1 is provided with openings 4 for fastening the wire 2 ^{and a} non-drying adhesive layer is applied on the inner sides of the roof surfaces 1, 2.

The roof surfaces 1, 2 may be composed of one sheet of rectangular shape, preferably 12 x 45 cm, which is covered by a press at a width of 2, 14, 22 and 30 centimeters. An adhesive surface is indicated on the inside of the film. The foil (actually the body of the trap, the roof surfaces 1, 2) / is shipped folded into a "sheet", without glue or preferably already applied with a non-drying glue. All handling of the application of the trap is to insert the film into the strengthening frame 2 ^and Tyni ^{and 3,} the adjustment of the shape of the two roof-shaped surface 4, 2 with a different cone angle, the fastening support attractant 6 and the hanging of the trap by means of a wire 7 passing through the apertures 4 ^{in the} roof-flat 1. Floo cha trap 2 (air inlet) is 26 - 27 cm. Trap shape 2 resp. its silhouette is based on the shape of the silhouette of a sitting female wrapping butterflies attracting males.

The catcher can be easily folded and packed into pieces of parcels and small packages together with other components. The adhesive can be applied directly in production or only when assembled on the marked surface.

The construction material may be different synthetic materials, wood, metal, preferably paper resistant to moisture, light, heat up to 60 ° p, white, light gray or light brown color.

This example illustrates but does not limit the scope of the invention.

Example

In a field experiment, the effectiveness of the trap according to the invention was compared with the so-called. tubular type, flowerpot type and with the type of opposite, in the middle of angled plates (approx. 150 ° angle), stick traps equipped with a weighing device / attractant 6 /, used in IT - Etocap traps. The experiment was performed in an apple orchard on days 27.6. - 4.7. 1983. The results are shown in the table.
