DESCRIPTION

1. Background of the invention

The present invention includes formulations and devices for effectively detecting crawling and flying arthropods; mainly insects, arachnids, and crustaceans such as woodlice, etc. These target arthropods with the maximum number of possibilities to attract, detain, kill as quickly as possible and without much suffering was the concern of this invention. In addition, the unskilled user, as well as children and pets, should not be exposed to any danger when handling such systems. The components used should, if possible, all be of natural origin, biodegradable and easy to handle.

Surprisingly, it has now been possible to bring together and exploit the synergy effects disclosed below in such a way that substantially better catch and control results in arthropods are the result of this invention.

2. State of the art

Systems for controlling crawling and flying arthropods have long been known. For example, traps baited with fruit juices or food in earlier times began, while bait formulations provided with contact or food poisoning only came to the fore with the advent of warfare agents. Protective bait stations were only used when poisoning cases increased. These specifically adapted housing types were used for the first time in the control of rats, later also against insects. An early attractant case system for detecting cockroaches is described by SC Johnson, already disclosed in patent 1915 US 1161388 , The expert commonly distinguishes two bait-based control methods. The mass catch trap with attractant and glue on the one hand, the bait station ("bait station") on the other. Both have specific advantages, but also their disadvantages. Bait stations have been described many times, there are numerous publications and patents. Bait stations are among others in patents WO 9115951 . WO 2006012180 . WO 2009153758 . NZ 237671 . US 5090153 . US 2009313883 etc. described. Advantages of these bait stations are the generally good accessibility of the poison bait by the insects and the protection against unintentional contact by bystanders. A disadvantage is the fact that semi-poisoned insects crawl around and fly freely on their way to food sources or their shelters. This can easily lead to unintentional contamination, secondary poisoning and drug resistance. Mass capture or monitoring systems as described in patents WO 2008063540 . US 5513465 . JP 61161201 . WO 2004098279 . CN 20201995492 etc. work with adhesive surfaces to permanently capture attracted insects. However, in these lock-containing but drug-free systems is disadvantageous to emphasize that often a so-called edge effect occurs, ie all detected insects are located at the edge of the adhesive surface; The number of trapped individuals is reduced to the center of the glued area or to the inside of the trap. As a result, such a system is always prematurely exhausted. In addition, the insects often suffer too long in an hour-to-day struggle for survival or death.

Adhesive systems must be seen in conjunction with suitable latch housings. in patents WO 9322909 . US 5182879 . CA 139195 . US D555753 . EP 1852016 some examples of different case casings are described. Good, suitable housing types exist for every purpose in a variety of forms, adhesive surfaces are adapted to their dimensions on the size side. Ideal sizes are standard dimensions of more than 10 cm edge length. The present invention was not related to case casings, but uses in this point commercially available products for insect detection (see. 1a ).

INVENTION

In view of the shortcomings described above, inherent to the known systems for controlling arthropods and the state of the art, an invention has been necessary, the formulations based on natural, biological degradable components in a synergistic way and thus offers an ultimate insect control system.

As support materials in the present invention polymer materials in the form of film and film-like support with moisture-resistant properties are used, which give the device shape and sufficient rigidity. Polymers as used in the plastics industry are e.g. Polyvinyl chloride (PVC), polyacrylonitrile (PAN), polyacrylate (PC), polyester (PES), polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), nylon or polyamide (PA), ethylene vinyl acetate copolymer (EVA ), Polyvinyl pyrrolidone (PVP), polyvinyl alcohol (PVA), etc., and mixtures of the above. By adding polymer disrupting additives, as known to those skilled in the art of polymer chemistry, biodegradable, compostable carrier films can be prepared at varying rates. (please refer 1c lowest layer).

The cover protective films used are single-layered or double-siliconised flat protective materials. These prevent the lure and active ingredients from releasing prematurely during storage and before use. For subsequent activation of the device, they can easily be removed by the user ( 1a right, 1c upper layer, 1b subtracted).

Disclosed polymeric materials can include pigments and particles of different hues. Color-controlled behavior-determining mechanisms are well known in arthropods. The person skilled in the art of color and polymer chemistry is aware that color pigments can already be part of polymer granules and can already be integrated in the production process of the films and films, in order to later have their colors. Flat polymers can also be dyed or printed in subsequent stages, or coated insect-adhesive substances can be enriched with color pigments. Suitable color pigments can come from the entire spectrum of known colors, including fluorescent, phosphorescent and reflective or metallic pigments. To monitor the appearance of insect populations, colored, white or black areas may also contain lines or patterns, e.g. B. in the form of Zählrastern, which make it easier for users of such systems to easily determine insect catch numbers and derive suitable further control measures.

The support materials of the invention disclosed and described herein are additionally coated with adhesive substances capable of permanently retaining attracted insects in the device. Pressure-sensitive adhesives for holding flying insects must have the functional property that attracted individuals can no longer move away and remain permanently on the adhesive matrix of the device. Suitable pressure-sensitive adhesives can be, for example, resin-based and provided with additives which increase or reduce the so-called "tack" depending on the requirement profile. Also, the additives can be nature-based nowadays, they are well known to those skilled in adhesive additives. He is also familiar that these pressure-sensitive adhesives and their mixtures are not or only very little as a function of time age, the Tack therefore adequately preserved. The adhesive substances used must have a sufficient layer thickness, so that the target arthropods can sink sufficiently and adhere so well to the target surfaces. Only this ensures that once detected insects can not escape. The present device can also be produced later, before use, with the help of the formulation provided in a cartridge itself. However, the ready-to-use Klebefallevorrichtung is the usual, which is activated only by peeling off the protective film.

Adhesive matrices of the disclosed device contain insect-blocking substances such as feeding attractants such as those disclosed in U.S. Pat. B. are used in cockroaches as gels or tablets. Their compositions are known to the person skilled in the art of attractant chemistry. In addition to milk powder, they often contain vegetable extracts and protein components of marine origin. In contrast, ants react more strongly to sugar-based attractants. Various species of beetles can be attracted well with animal protein-based attractants. Many of these feed attractants have food quality and are therefore safe to use. In addition to the Fraßlockstoffen still exists the large field of natural or nature-identical pheromones. These are usually synthesized today derived from nature. They cause species-specific behavioral changes in the target insects such. For example, the imitation of a tempting female moth or the call for conspecifics to gather. Examples of such pheromone substances include house fly Z-9 TRICOS (Musca domestica); Z, E-9,12-TETRADECADIEN-1-OL of the dried fruit moth (Plodia interpunctella) or OCTENOL attracting mosquitoes and gels etc. Occasionally, food additives, fragrances, perfumes and aromas may be used alone or in combination Commitment. All the attractants used are located in the active substance depot surrounded by the adhesive in the most ideal environment. The attractants migrate slowly through the adhesive matrix following the concentration gradient to the surface, from there into the environment of the control system, where they can already be detected by the insects in traces. These already preferred release profiles can be further optimized, if required, by microencapsulation and bio-microcolloid solutions, but as a rule this is not necessary. The attractants used are ideally located in the tapered drug depots (see 1b and 1c However, in certain cases, it may also be incorporated in the adhesive matrix surrounding the active substance cones. However, this is only the case of pronounced incompatibilities between agents and attractants of the case and represents a technical exception solution.

The present invention contains insecticides as known to the expert in insecticides. The insecticides used are preferably more natural and only in exceptional cases of chemical origin, the latter only if biological active agent representatives are not available or have to withdraw for effect profile side reasons. They come as a contact or feed, ie after dermal or oral intake by the insect used. The active substance depots are in the present invention as a tapered, upside-down cone in the lower, the carrier material facing part of the adhesive matrix (see 1b and 1c ). The upside-down arrangement of the drug depots enables the present system to have incorporated into the adhesive matrix attractants and attractants on the one hand technically good and clean and on the other to offer the largest possible release surface for the active ingredients and attractants used (see indicated release of active ingredient in 1c , Drug depot left of the center). Lured insects absorb the active substances in lethal dose as volatile molecules in sufficient quantity or get directly to the depots by slight sinking of the head, thorax, abdomen and extremities in the adhesive matrix. As a result, the uptake of active substance leads to a rapid deterioration of the pests and pests. Takes the life of the adhesive matrix due to the high number of detected individuals to the end, so it is still so compared to conventional Klebefallensystemen that attracted arthropods can get through the ideal surface distribution of Depotverteilmusters to the active ingredients, absorb them and thus killed become. Systems based on the present invention are more than twice as effective as the commercial standard. In addition, they offer a maximum level of safety, since the active ingredients are not concentrated and selectively highly concentrated, but well distributed and with the lowest amount of active ingredient per depot point. In addition, inadvertent contact with the adhesive matrix usually only results in the agent depot being pushed downwards in the direction of the carrier material due to its shape, contact being therefore virtually excluded. Sticky fingers are usually immediately cleaned after unintentional contact anyway, so that any traces of active ingredient on this obvious cleaning process are removed with the same. Nevertheless, the combination of adhesive matrix with attractants and attractants should never be done without a secure, adapted trap housing.

In recognition of the above-mentioned details, in the present invention described in the illustrated embodiment and illustrated by the present drawings, it is also possible to make modifications of the formulations and apparatuses which are in accordance with the spirit of the invention and described by the following claims.
