At present veterinary pest control studies focus on development of effective and simple insecticides. There is a growing demand for modern environmentally friendly insecticides; for example those made of plant-based raw materials. In this research we have studied the insecticidal effect of the mixture of fipronil and fir oil on adult species of Musca domestica as well as its permanence and cryostability. Mixtures of fipronil and fir oil in ratios 1:225, 1:450, 1:900 and 1:1800 have been tested. In all cases, the nature of the component interaction was additive. The greatest value of the combination index was found in 1:450 ratio. This mixture used against adult flies is classified as of average effeciency, fast-acting with an irreversible insecticidal effect. Lethal doses LD50, LD84 and LD99 of the mixture (1:450) for flies have been determined according to the type of the treated surface. Acute toxicity of the mixture for mice (hazard class II in accordance with GOST 12.1.007-76) has been determined.References:
