| description | Background & objectives: Phlebotomus argentipes is the vector for visceral leishmaniasis in India. Thedevelopment of resistance in kala-azar vector to DDT has been reported from various parts of India. The mainobjective of this study was to generate information on insecticides susceptibility status of P. argentipes to DDT,malathion and deltamethrin in different parts in three states of India.Methods: Phlebotomus argentipes were collected from different villages, identified and used to investigate thesusceptibility status against DDT, malathion and deltamethrin as per the WHO standard methods.Results: Phlebotomus argentipes was resistant to DDT in different areas, viz. PHCs Murumgaon in Maharashtra;Ramgarh in Jharkhand; Kodah, Falka, Mahua and Lalganj in Bihar. In Phulwari Shareef PHC of Patna districtin Bihar, DDT produced 89% mortality in P. argentipes, indicating resistant/tolerance (verification required) toDDT. The corrected percent mortality to malathion (5%) in different areas ranged between 98 and 100%; and todeltamethrin (0.05%) between 98.4 and 100%. The results showed that the tested P. argentipes are susceptibleto malathion and deltamethrin.Conclusion: Phlebotomus argentipes are still susceptible to malathion and deltamethrin, but resistant to DDT.The susceptibility status of P. argentipes should be monitored regularly in diversified situations to ascertain thejudicious use of insecticides being used for indoor residual spraying in the programme for rational use ofappropriate insecticide. |
