Abstract: A field study was carried out in a village of Phetchabun Province, Thailand to evaluate the behavioral resistance of Anopheles dirus to indoor residual spraying of DDT and fenitrothion (FNT). Among four experimental huts three were sprayed with 2g and 1g of DDT, and 1g of FNT per m^2. Indoor and outdoor human bait collections were performed before and after the treatment for six months. The ratio of indoor biting density to outdoor one (IBD/OBD) was prominently reduced after the treatment in a hut with 2g of DDT. The reduction was also ascertained in huts with 1g of DDT and FNT. The reduction on the ratio of indoor resting density to indoor biting density (IRD/IBD) after the treatment suggested presence of the behavioral resistance of the species to those insecticides.
