Abstract

Insecticidal agent for controlling difficult and harmful insects especially flies Domestic (Musea domestica) pyrethroids, a means of enabling them mixing with substrates of decomposition processes characterized in that it consists of 3.00% to 0.0005 wt. pyrethroids, 3.00% to 0.0002 wt. emulsifiers, organic solvents, adhesives and 94.00% to 99.999% wt. substrates of decomposition processes. The use of the invention falls within the health sector, agriculture, chemical industry and into the tertiary sphere, households. The purpose of the invention is to reduce the occurrence of above all House flies (Musea domestica) and vos.

Description

SUMMARY OF THE INVENTION The present invention relates to an insecticidal composition for controlling harmful β-difficult insects which feed on products of decomposition processes, in particular houseflies.

At present, insecticidal contact means are used to control difficult insects in enclosed spaces, which are applied by spraying or are gassed.

The mechanical means are used against house fly flies, or. other mechanisms. In addition to mechanical means, which usually have very little efficacy, other means have a common denominator in high toxicity not only to insects but also to other living organisms in the vicinity. The exception is pyrethroids, which are very effective against insects and almost non-toxic. However, the pyrethrin contained eg in Biolit is bound to the repellent material.

When spraying with these types of means the condition is a stable without animals, the apartments must be ventilated, there is a danger of splashing food, things.

Actellic, Biolit spray aerosol formulations are available in costly pressure vessels, where overpressure is provided by freon gas, which causes ozone decomposition in the atmosphere and thus a rapid drop, which is regarded by experts as very dangerous. Therefore, it is an attempt to replace this type of resources.

SUMMARY OF THE INVENTION The present invention provides an insecticidal composition for controlling difficult and harmful insects which feed on decomposition process products containing from about 3.00% to about 0.0005% by weight. % pyrethroids, 3.00% to 0.0005% wt. % of emulsifiers, organic solvents, adhesives and 94.00% to 99.9990% wt. substrates of decomposition processes.

The invention furthermore consists in mixing and / or mixing these materials. Inoculate kvao sinka and spread on a dish of about 70 to 100 cm. A novel and superior effect of the composition according to the invention is that pyrethroid is used in pure form, free of additives and repellents. Once dissolved, it is mixed with materials attractive to harmful and difficult insects.

As a result, the insects are sought after. In case of fire or contact with this substance, contact with the active substance occurs. This causes it to become paralysis, which is pstring within 1 to 2 minutes.

Death occurs within 1 to 2 hours. At this time, the insects are trying to fly out of the confined space outside the light. Said composition operates continuously provided that the degradation process is maintained, for example, with milk or sugar with water. Its properties are predestined for continuous biological combat especially with housefly. Its production is unpretentious, cheap compared to current means.

The present invention is described in more detail in the following examples. The pure permethrin used is characterized by the manufacturer as 21.3% cis isomer and 78.7% trans isomer. It is stable to light, water, oxygenation and temperature up to 40 ° C. Its toxicity is at a dose of 20 g / kg body weight (tested in rats). For spray application, 5g of pure substance / ha is sufficient.

For the feeding and possibly tactile way of carrying out the composition according to the invention:

Example 1

0.1 g permethrin 0.49 wt.

0.1 g of edible soybean oil 0.49 wt.

10.0 g cereal meal 49.50 wt.

10.0 g water 49.50 wt.

WITH

Example 2

0.05 g permethrin 0.25 wt.

0.05 g of edible soybean oil 0.25 wt.

0.50 g of yeast 0.50 wt.

10.00 g of wheat flour 49.50 wt.

10.00 g milk 49.50 wt.

Permethrin was spread in edible soybean oil, mixed with cereal meal, water or milk, and again spread and spread on a 100 sm dish.

When an emulsifier, organic solvent, adhesive is used, there is no risk of toxicity to other organisms in the surrounding, besides insects, which feed on the products of degradation processes, thus ensuring risk-free use in households, food processing plants, stables, etc. hygienic conditions at the time of application, since the composition does not have a repellent effect on its surroundings, as opposed to, for example, Biolit or Actellic. Bees don't find him. Paralyzed flies look for wasps. After fire, they become paralyzed and die.

If by this means it is possible to reduce or completely eliminate house flies in stables, it is possible to count on an increase in efficiency of animals by 5 to 10%.

Claims (2)
