Abstract
Susceptibility status of Indian kala-azar vector Phlebotomus argentipes after DDT spray from endemic areas of Muzaffarpur and Vaishali district and unsprayed non-endemic area of Patna district, Bihar, India were compared. Higher Lc50 viz. 2.6% and 3.2% and LT50, values 51.0 and 69.0 minutes to 4% DDT were observed for P. argentipes of Muzaffarpur and Vaishali district, whereas P. argentipes of Patna district was 100% susceptible to same concentration, indicating increased tolerance in P. argentipes. It is concluded DDT resistant P. argentipes, particularly in endemic zone growing. The possible explanation could be long-term insecticidal pressure.Entities:
