[The activity of cyfluthrin and cypermethrin-based preparations against the vector of the causative agent of tick-borne relapsing fever].

Laboratory tests have established a high activity and long-term persistence of some cipermethrin isomers (fendone, fastac) and cifluthrin (zolfac) against the tick Ornithodoros papillipes, a carrier of tick-borne relapsing fever. These indices are considerably superior to those of an isomer mixture of cipermethrin (cimbush, ripkord). This can be applied to deltamethrin and cigalothrin. The findings suggest that these agents are highly promising in controlling the carrier of tick-borne relapsing fever along with a significant reduction in the ecological pesticidal load in the focus.
