Description

 The invention relates to the field of entomology and will find application for the fight against ants in residential, public buildings, food units, etc.

 Recently, a large number of ants have appeared in residential and other premises where people and pets live, as well as food products, which cause material damage.

 The fight against this type of insect is carried out mainly by chemical means of protection, which are toxic and can pose a threat to humans and domestic animals, and can also be a source of toxicity when ingested with food.

 Conducted research on patent and scientific literature revealed a number of chemicals used to control insects in residential and other premises. So, from insecticides of intestinal action, arsenic compounds were recommended — arsenates of calcium and lead, sodium and calcium; barium chloride and carbon dioxide compounds; fluorine compounds; sodium fluoride and silicon fluoride; tetraarylphosphonium phosphorus salts and sulfur; substituted thioureas and aromatic sulfonic acids.

 Recently, in accordance with a number of guidelines developed by the Scientific Research Institute of Disinfection and Sterilization M3 and the Institute of Medical Parasitology and Tropical Medicine and approved by the Chief State Sanitary Doctor (letters N 28/3 of 01/23/86; N 28 6/17 of 7.06 .83), FOS group preparations are used for disinsection, such as karbofos, malathion, TH 40-49, as well as hexochlorane poison of contact, intestinal and mixed action, belonging to class 1 of extremely dangerous substances. The main disadvantage of these insecticides is the adverse adverse effect on warm-blooded animals and humans.

 High specific toxicity is characteristic of contact insecticides, which include plant poisons (nicotine, anabazine, mash), as well as synthetic drugs.

Insecticides are used in the form of powders, solutions, emulsions, suspensions
for spraying with aerosols, in the form of poisoned baits and for fumigation.

 The most important requirements for insecticides are high toxicity to insects, sufficient stability during storage, transportation and use, safe handling (non-flammability, non-explosive). The most important thing is that most of the used insecticides are toxic to humans and animals, when they are used, it is necessary to remove food from the premises or carefully cover it, drinking water, during disinfestation it is necessary to free the premises from people and animals. Most drugs have a sharp specific odor and have an adverse effect on the respiratory system.

 Analysis of the available literature also confirms the low effectiveness of known insecticides in the fight against ants.

 As a prototype, malathion, used in the form of a wetting powder (1), was selected (methodological recommendations of the Ministry of Health of 7.06.83 N 28 6/17 were approved). It is used for disinsection in the fight against household parasites, blood-sucking two-winged insects and ticks. Malathion (karbofos, preparation TN 40-49) belongs to the FOS group, a colorless or yellowish liquid with a strong specific odor. The drug is insoluble in water, soluble in most plant solvents. Malathion refers to compounds of moderate toxicity for warm-blooded animals. LD -50 for rats -400- 1400 mg / kg, when applied to the skin of rabbits -4000-6150 mg / kg.

 Subject to safety precautions, it does not reduce the activity of cholinesterase, however, when used in a number of countries with a hot climate, severe poisoning occurred when humans and animals came into contact with it.

 The duration of the residual effect depends on the nature of the surface, the form of its use, air and humidity (within 2-5 months). It has an unpleasant odor. Processing of premises is carried out in the absence of people, animals, food. Storage and transportation are also complicated due to the toxicity of the drug.

 The aim of the invention is the prevention of toxic side effects of insecticides on humans, pets and food. This goal is achieved by preparing a mixture of the active substance and an indifferent additive. The killed yeast of microbiological production was taken as the active substance, and chalk, for example, as an indifferent additive (adjuvant). An insecticidal ant control agent is prepared as follows: take a sample of any microbiological yeast (for example, hydrolytic or food), mix with its adjuvant in a ratio of 3: 1 (3 parts yeast and 1 part adjuvant, then the resulting mixture is scattered in places the largest accumulation of ants.This product does not lose its properties for a long time.The ants under these conditions disappear from the habitat within 2-3 days.The product is non-toxic, has no negative effect on humans Or to domestic animals has no unpleasant odor.

 Example 1. 15 g of hydrolytic yeast powder was mixed with 5 g of chalk, sprinkled in the place of accumulation of ants in a food dairy laboratory. During the first day, the ants intensively carried away this mixture, while their number decreased sharply, and after 2 days they completely disappeared, and their death in the places where the agent was located was observed in exceptional cases.

 Example 2. In a food refrigerator, a thermal relay failed. On examination, a large accumulation of ants was found that destroyed the electrical insulation. After repairs in the place where an ant cluster was noted, the proposed mixture was sprinkled, after 2 days the ants in the place disappeared from the place of stay.

 A toxicity test was carried out in the Problem Laboratory of the Rostov Medical Institute in accordance with the instructions of the Ministry of Health of the Russian Federation (M. 1982).

 A chronic toxicological experiment (24 months) was conducted on two types of laboratory animals (rats, rabbits). Conclusion: in the doses recommended for use, it is not toxic.

 Compared with the prototype, the proposed insecticidal agent for combating ants in a human environment has the following advantages: lack of toxicity, the duration of preservation of properties, the absence of an unpleasant odor, does not have a harmful effect on humans or domestic animals, the death of ants occurs outside the human environment .
