摘要:Introduction. Despite the increased rates of infestations with I. ricinus (Ir) and D. reticulatus (Dr) ticks observed over the lastdecade, no effective control methods have been developed so far. The present study was focused on assessment of theaction of pyrethroids on these both tick species.Materials and method. The different doses of four pyrethroids, i.e. deltamethrin – D (K-Othrine), permethrin – P (Copex WP),cypermethrin – C (Kordon 10WP), and alphacypermethrin – AC (Alfasekt 5SC) were tested. The LD50 for each tested compoundwas also determined for both tick species. Unengorged and engorged (maintained on rabbit skin) tick females were sprayedwith 20ml of 0.01563–0.50% solutions of the tested preparations.Results. The investigations showed that sensitivity of Ir and Dr to the tested pyrethroids, but the effects exerted by thedifferent doses varied between both tick species and between engorged and unengorged females in these species. Thestrongest toxic effect on unengorged and engorged Ir and Dr females was exerted by D, whereas the effect of AC wasweaker. The LD 50 (in μg/1 g b.w.) of D, AC, C, and P for unengorged Ir and Dr females was, respectively, 55.4 and 25.5, 105.2and 48.5, 225.9 and 197.7, and 553.8 and 380.8. In the case of engorged Ir and Dr females, the LD50 of AC, D, C, and P reacheda value of 0.9453 and 0.2310, 1.0428 and 1.3533, 3.489 and 6.5662, and 8.3955 and 7.3940, respectively.Conclusions. The differences between the effects of the tested pyrethroids and their different doses on Ir and Dr highlightthe necessity for development of a strategy for control of the tick species in different regions, based on investigations oftheir sensitivity to chemical compounds
