Abstract

Described is an insect control device comprising a smoldering paper carrier, characterized in that it is provided with at least one insecticidal active ingredient.

Description

The The present invention relates to an insecticidal active ingredient soaked Paper, process for its preparation and its use for fight of insects.

Known is that to mortify or repellant of insects, e.g. Mosquitoes, with the help of electrical heaters e.g. so-called platelet evaporator can be used. In this process suitable substances, e.g. cellulose and cotton cardboard, asbestos, ceramics and / or porous synthetic resins containing insecticides Active ingredient solutions impregnated being insecticidal platelets to be obtained. The insecticides are made by the action of a heater, which produces a temperature of 120 to 190 ° C, volatilized.

One considerable disadvantage of this platelet evaporator is that these vaporizers the active ingredients on the Do not dispense the intended duration of action uniformly. The drug delivery is usually unnecessarily high at the beginning of commissioning and then falls continuously and strong. The effectiveness of these evaporator platelets in the course the specified period of application.

since longer Time is also evaporators for the Domestic use known, for example, in GB-B-2 153 227 are described; here, the evaporation of a solution, wherein the active ingredient e.g. in a mixture of saturated aliphatic hydrocarbons solved is, by means of an electrically heated wick.

The in these so-called liquid evaporators needed in relation to significant amount of organic solvent to the amount of active ingredient leads the product application to an undesirably high concentration of solvent in the room, which among other things led to pollution, which is often criticized by consumers of walls and objects, which are close by of these devices located, leads.

To ward off the annoying insect pest battery-operated insecticide evaporators are known in which the surface of a radiation plate is heated to evaporate an insecticide to a temperature between 90 and 130 ° C ( DE 195 25 782 A1 ).

In addition, from the DE 20 2004 008 226 U1 An insect control fuel body, in particular for grilling, which comprises a carrier structure provided with pores and / or cavities and a fuel of wax and / or paraffin and / or stearin, the fuel having a proportion of citronella oil.

Farther It is known to vaporize insecticides by means of electrical means Operated fans, which have an airflow over one with an insecticide drug solution impregnated carrier blow. Such fan systems are e.g. in WO-A-96/32843.

Out EP-B-0 279 325 are transfluthrin impregnated natural and synthetic Fabrics, e.g. also moth papers, known.

Furthermore, smoking spirals, such as Baygon ^® spirals (coils) are known, which protect for a period of 6 to 12 hours from mosquitoes, for example, on the terrace, on the balcony, camping or in the room. To use the rings they are lit, the ring smoldering, so that the containing active ingredient is released slowly and continuously outdoors or in the room. For a space of about 20 m ² , a commercially available ring is needed. A disadvantage of these rings, however, is that they tend to break easily in use, so that they are only partially used.

Furthermore be fighting of insect aerosols or oil sprays used to closed spaces quickly rid of insects. Treated rooms can then subsequently aired again as long as the access of new insects can be prevented. However, corresponding systems have the disadvantage that the aerosol mist or the oil mist due their mass in the rooms do not distribute it sufficiently fine.

All these products have in common that they are technically and logistically complex, slow and therefore expensive to produce. Furthermore, the production of the world's largest volume of aerosols, oil sprays and spirals requires the consumption of enormous amounts of natural resources such as kerosenes, propane / butane, wood flour, glue, starch and various formulation aids. Furthermore, their use requires usually the subsequent disposal of appropriate packaging, such as cans, valves, plastic bottles, outer packaging, etc.

Consequently turns out for the expert considering of the prior art described above, the task of a device for insect control to provide the disadvantages presented above largely avoids.

The solution this task is based on an insect control device, which one glowable paper carrier includes.

7.1 Culex quinquefasciatus

The mosquitoes are kept in cages (48 × 48 × 39 cm) with gauze inserts on the sides and in the lid. The lighting (day / night rhythm) is controlled by a timer (12 hours light / 12 hours dark), at a temperature of 26 ° C ± 1 ° C and a relative humidity of 60% ± 10%. To absorb liquid, the mosquitoes are placed in the box a cotton ball soaked in 10% glucose solution. An artificial blood feeding is done twice a week. Bovine blood mixed with an anticoagulant is heated to 40 ° C using a magnetic stirrer. Approximately 50 ml of this blood is poured into a piece of pig intestine and placed in the breeding box at closing. This allows the mosquitoes to absorb blood. For oviposition a bowl (diameter 10 cm), which is 2 cm high filled with tap water, placed in the breeding box. The discarded eggs are transferred to a plastic tray (25 × 37 cm) filled with 5 liters of demineralised water and placed on a terrarium heating mat. Once a day, the mosquito larvae are fed with commercially available ornamental dry fish food (eg Vita ^® ). After about 6 days, the pupal stage is reached. These are, with a small amount of water, for the hatching of mosquitoes, transferred to 10 liter plastic buckets. The resulting mosquitoes can then be intercepted for examinations or for further breeding.
