Efficacy of Different Lambda-Cyhalothrin Formulations against Ticks

Abstract

Ticks (Acari:Ixodida) are arthropods of special biomedical importance, well known as transmitters of several zoonotic diseases. Various acaricides have been used to control them but their number has decreased over the years. Having this in mind, we examined in 2003-2005 the possibility of using a 5% microemulsion and an EC formulation of lambda-cyhalothrin to control ticks on dogs and sheep, and in houses. The 5% microemulsion of lambda-cyhalothrine caused tick mortality after 2-3 minutes. The efficacy of the 5% EC formulation of lambda-cyhalothrin was unsatisfactory.

Krpelji (Acari:Ixodida) su artropode poznati kao vektori mnoštva zoonotskih oboljenja. Parazitiraju tokom hranjenja na sisarima, pticama i gmizavcima. Suzbijaju se primenom širokog spektra akaricida čiji se broj svake godine sve više ograničava. Imajući to u vidu tokom 2003-2005. godine izvršena su ispitivanja mogućnosti primene 5% mikroemulzije i EC formulacije lambda-cihalotrina u svrhu suzbijanja krpelja. Primenom 5% mikroemulzije lambda-cihalotrina dolazilo je do uginuća krpelja u roku 2-3 minuta. Efekat EC formulacije nije dao zadovoljavajuće rezultate.
