Malathion and Propoxur Resistance in Turkish Populations of the Anopheles maculipennis Meigen (Diptera: Culicidae) and Relation to the Insensitive Acetylcholinesterase

Abstract

Our results revealed that insecticide resistance against malathion and propoxur increased from 2007 to 2008. Biochemical assay results showed that the AChE insensitivity for 2 test years and insensitive AChE frequency had increased annually. Our results also showed that extensive usage of organophosphate and carbamate for pest control in agriculture is a key factor for malathion and propoxur resistance in all tested populations rather than direct usage of mosquito control.
