Field collected fully fed adults of Phlebotomus argentipes and P. papatasi were screened in the laboratory for susceptibility to DDT, BHC, malathion, deltamethrin, permethrin, lambdacyhalothrin and bendiocarb. Pondichery strain of P. papatasi and P. argentipes showed variations in their susceptibility to insecticides. Both the species were resistant to permethrin but tolerant to DDT and malathion with LD99.99 values of 13.88, 1.92, 1.08 and 34.63, 4.69, 16.32 times more than the deterministic doses respectively. However, they were susceptible to bendiocarb with LD99.99 7.6 and 1.6 times lower than the deterministic doses. While P. papatasi was susceptible to BHC, P. argentipes showed tolerance (1.6 times). The former showed tolerance to deltamethrin and the latter exhibited resistance (34 times). It was reverse in case of lamdacyhalothrin. High susceptibility of the vector sandflies to bendiocarb suggests that this insecticide could be used effectively against OP and pyrethroid resistant populations for Kalaazar control.

UI	MeSH Term	Description	Entries
D007306	Insecticides	Pesticides designed to control insects that are harmful to man. The insects may be directly harmful, as those acting as disease vectors, or indirectly harmful, as destroyers of crops, food products, or textile fabrics.	Insecticide
D010691	Phlebotomus	A genus of PSYCHODIDAE which functions as the vector of a number of pathogenic organisms, including LEISHMANIA DONOVANI; LEISHMANIA TROPICA; Bartonella bacilliformis, and the Pappataci fever virus (SANDFLY FEVER NAPLES VIRUS).
D004351	Drug Resistance	Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.	Resistance, Drug
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
