Antagonistic Effect of Azadirachtin on Cyfluthrin and Permethrin
A. Salehzadeha and H. Mahjub

Abstract:
The aim of this study was to assess the efficacy of some traditional pesticides either individually or in combination, against Blattella germanica (Linnaeus) (Dictyoptera: Blattellidae). Cockroaches are of great public health importance worldwide and chemical methods remain one of the most popular approaches to combat the problem. Using contact method German cockroaches were exposed to pesticides in glass jars containing pesticides. The results showed that maximum knockdown was achieved with 0.5 cyfluthrin with KT50 of 8.9 min. The KT50 values for 0.1% permethrin, 2.5% Primifos methyl, 2. 5 and 5% malathion, 0.0 and 5% Diazinone, and also 0.25 and 0.5% Bendiocarb were 13.8, 88.03, 131.4, 75.16, 86.94, 41.08, 103.5 and 42.9 min, respectively. Surprisingly the combination of azadirachtin with permethrin or cyfluthrin showed the least effect which could be due to competition of azadirachtin and pyrethoids for same site or some conformational changes in target sites or receptors.
