[The results of laboratory and field trials of the action of ektomin on the taiga tick].

Laboratory and field trials of 60% concentrated ectomin emulsion have been conducted. Laboratory experiments on the contact of hungry female individuals of Ixodes persulcatus (Acarina, Ixodidae) with pesticide in the envelopes made of impregnated filter paper have established high imago sensitivity to the preparation--LD50 after a 4-hour contact was 1.10(-6) micrograms/cm2. In field experiments ectomin ensured a 100% effect of hungry Ixodes persulcatus elimination 1-2 days later, with the preparation expenditure no more than 0.05 kg/hectare. The effect was retained throughout one whole season of I. persulcatus activity.
