CS229018B1 - Insecticidal agent for controlling insects that feed on food or their waste - Google Patents

Abstract

Insecticidal agent for the control of troublesome and harmful insects that feed on food or its waste, characterized in that it consists of 3.00% to 0.0005% by weight of pyrethroids, 3.00% to 0.0005% by weight of emulsifiers, organic solvents, adhesives and 94.00% to 99.999% by weight of food or its waste. The use of the invention falls within the sectors of healthcare, agriculture, chemical industry, tertiary sector, households. The purpose of the invention is to reduce the occurrence of pests of food or its waste.

Description

The present invention provides an insecticidal composition for controlling difficult and harmful insects that feed on food or waste.

At present, ineecticidal contact preparations are used to control difficult and harmful insects which feed on food or waste, and which are applied aa as a coat or as a gas to these areas. Newly developed hormonal substance that prevents the development of offspring, for example, Pharaonic ants. Mechanical means are of little importance.

The compositions used have a common denominator in high toxicity not only to insects, but 1 other living organisms in the vicinity. The exception is pyrathroids, which are very effective against insects and almost non-toxic to the environment. However, the pyrethrin contained eg in Biolit is bound to the repellent material. When spraying with these types of equipment, the flats must be ventilated; if the eye hits the doctor immediately, there is a risk of splashing food. When gassing flats it is necessary to leave the flats. 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 inecticidal composition for controlling harmful and harmful insects which feed on food or waste thereof, comprising from 3.00% to 0.0005% by weight. % pyrethroids, 3.00% to 0.0005% wt. % of emulsifiers, organic solvents, adhesives and 94.00% to 99.999% by weight of the composition; food, eventually their waste.

It is a further object of the present invention to mix and distribute these materials, or the like, for example, dry sausage, fruit juice, syrup, and spread over the places visited by insects.

A novel and superior effect of the composition according to the invention is that the pyrethroid is used in pure form, without the addition of repellents, and that foodstuffs attractive to this type of insect are bound, and consequently sought after by the insects. In case of fire or contact with this substance, contact with the active substance occurs. This causes paralysis and death. E.g. Pharaoh's ant within minutes of fire or touch.

Said composition operates continuously for a long time. It is unpretentious, inexpensive, nontoxic to other organisms, non-repellent when used with an appropriate emulsifier, organic solvent, antioxidant, and is therefore predestined to reduce this type of insect in households between foods, hospitals, etc. Later, the undeveloped next generation, such as the Pharaoh ant, this product stands out for its immediate toxic action.

The present invention is illustrated by the following examples.

An example of an insecticide for food insect control or food waste is: The pure permethrin used is characterized by the manufacturer as the 21.3? Cis isomer and 78.7? Trans isomer. It is stable to light, water, oxygenation and temperatures up to 40 ° C and toxicity of 20 g / kg body weight - tested in rats. For areal application, 5 g of pure substance / ha is sufficient.

For the fire and tactile embodiment of the insecticide composition according to the invention:

Example

0.1 g permethrin 0.1 g edible soybean oil 10.0 g fruit syrup 10.0 g breadcrumbs

0.49% wt. 0.49 ® wt. 49.51. # wt. 49.51 ® wt.

Example 2

0.05 g of permethrin

0.05 g of edible soybean oil

20,50 g fruit syrup

Example 3

0.1 g permethrin 0.1 g edible soybean oil 20.0 g dry salami

0.25 wt. 0.25 wt.

99.50 wt.

0.49% by weight 0.49% by weight

99.02 wt

Said inaectioid composition according to the invention can be used in households, health care, the food industry, the tertiary sphere of agriculture and the like without secondary harmful effects on the environment and other living organisms. It is unpretentious, cheap and due to its long-term effect it can be represented by products such as Biolit spray, spraying, gassing, because it is sufficient to set up the product in places where this type of insect occurs.
