Insecticide-induced behavioral responses in two populations of Anopheles maculatus and Anopheles sawadwongporni, malaria vectors in Thailand.

Behavioral responses of 2 wild-caught populations of Anopheles maculatus (Theobald) and Anopheles sawadwongporni Rattanarithikul and Green to operational field doses of DDT (2 g/m2) and permethrin (0.5 g/m2) were characterized using an excito-repellency test system. Both test populations, collected from animal quarters at Ban Pu Teuy, Sai Yok District, Kanchanaburi Province, western Thailand, were found completely susceptible to DDT and permethrin.
