Description

(57)

Equipment for controlling the population density of insects, resp. The arthropods comprise an evaporator with an attractant, in particular a pheromone, and a means for contaminating an insect overpressing the insect killing agent. in particular a biopesticide or reproductive agent, which may preferably be in the form of a hollow cylinder (9) closed at both ends of the lid (6) with an inlet (7) and an escape (8) aperture, provided with a reromonas evaporator inside the cylinder and hinge or consisting of a funnel-shaped sheath (2) into which the impact surfaces (1) provided with a cross-insect control means are inserted, in the center of which is an evaporator (4) with attractant and hoods (3) located above the impact surfaces ( 1).

Equipment for regulation of insect population density

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a device for controlling the population density of insects, respectively. arthropods.

BACKGROUND OF THE INVENTION

A generally accepted environmentally sound strategy for reducing insect damage is integrated pest management: Integrated Fist Management - ΙΡΜ, νίζ the definition of FAO and IOBC / WPRS. IPM recommends the targeted use of selective means and methods that are species friendly and indifferent and that therefore do not compromise species diversity and the stability of ecological systems. It is desirable to eliminate the widespread use of pesticides. Presently, chemical-free food production systems based on bioagens are sprayed. At present, however, this method is so economically demanding that its spread worldwide is minimal. In addition, bioagens can not be sprayed in diverse gardens, alleys, roads, inaccessible areas such as tall trees, etc.

For many insect pests, respectively. Arthropods are known attractants effective for males, mostly based on sexual pheromones secreted by non-fertilized females. These attractants have hitherto been mainly used in traps for monitoring the occurrence of pests. To a lesser extent and for only a few pest species, attractants, for example based on aggregation pheromones, are used as a direct trapping agent. This method is effective only if females are also attracted to the traps.

The proposed device is derived from several types of pheromone traps, usable for monitoring and / or mass capture of insects. See, for example, the author's certificate No.257503 of Czechoslovakia from February 20, 1990 - PV 419-85 and other patterns of traps, including foreign ones. In principle, however, the proposed device differs from the above-mentioned designs in its construction and function.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The present invention relates to an insect population density control device which comprises an effluent from which an attractant is released and a means for contaminating attracted insects with a killing agent, in particular a biopesticide or reproductive agent. The most commonly used insecticides are biopesticides, in particular preparations based on entomopathogenic viruses, or sterilants from the group of substances mimicking the effects of juvenile hormones.

The device may be in the form of a blank rolled into a hollow cylinder by means of rings. The cylinder is closed at both ends of the lid with a port and an escape opening. Inside the cylinder there is a pheromone evaporator and insect control agent. The ..

Another variant is a device consisting of a funnel-shaped casing into which the impact surfaces assembled in a cross are inserted, in the center of which there is an attractant with an attractant, and the roofs placed above the impact surfaces. The impact surfaces are provided with means for killing insects.

Unlike previously used insect monitoring or trapping trays that are equipped with adhesive inserts or containers to attract the attracted insects, the designed trap is designed to contaminate the attracted insects inside the trap with a killing agent applied to a suitably treated internal surface. the openings are designed to free the lured and subsequently contaminated insects from being trapped. In general, males are expected to be attracted by sex pheromone, who, after being contaminated with a killing agent, find females for mating.

The traps can be made of any material, such as plastics or suitably treated cardboard. Two variants of traps are envisaged. A. A reusable, multi-year use trap will be made of a durable material and provided with an inner, easily replaceable liner of an easily degradable material carrying a killing agent. B. Single use disposable paste, made entirely of easily degradable, environmentally friendly material. The material used must not be insect repellent and should have a neutral, natural environment of its own color. Attractants, such as pheromone removers, specifically effective for individual species are used to attract insect pests. As the contamination agent, the inner surface of the trap is suitably treated, e.g., coated with a pile fabric, dusted with a killing agent or a layer of gypsum or plastic paste with a killing agent as an additive.

DETAILED DESCRIPTION OF THE INVENTION

He did. The inner side of the blank is provided with a means for contamination with a killing agent, for example, in a population density control trap, Cydia pomonella, with a preparation containing the apple granule virus or a suitable juvenoid of a similar spectrum of activity as the preparations for phenoxycarb base. The blank is rolled into the shape of a tube 9, threaded past the suspension wire 4, which at the same time serves to fix the flue 5 containing the synthetically prepared main component of the female sex pheromone - codlemone. The coiled blank is fixed at both ends by means of wire rings 3 and is closed from both sides by funnel-shaped plastic caps 6 with a sickle-shaped escape opening 8 in the lower edge. (See Figure 1)

Example 2.

The impact surfaces 1 assembled in a cross are provided with a suitable carrier of the killing agent and inserted into the sheath 2 in the form of a shortened funnel. In the center of the cross formed by the impact surfaces 1, an attractant 5 is attached. E.g. when using a population density trap of Lymantria dispar, a preparation containing the polyedry virus of the daisy or a suitable sterile, a pheromone discharger containing a disparlure is used as the attractant. a roof 3 with a hinge 6 is fastened above the impact surfaces 1 inserted in the housing 2. (see Fig. 2.) ..... ........-........

Example 3.

The impact surfaces 3 assembled in a cross are provided with a suitable carrier for controlling the agent and are inserted between the upper part 2 and the lower part I of the wing-trap. An attractant 4 with an attractant is fixed in the center of the cross. The entire paste may be of easily degradable material, for example, of refined cardboard, which resists the weather for a period of time and can easily be destroyed by burning upon termination.

Industrial applicability

The device according to the invention can be used in agriculture, forestry and in agricultural product and food stores, in particular against pests of the order Lepidoptera.
