Résumé

The impact of spraying Deltamethrin 2.5% w.d.p. @ 20 mg/m2 and its comparison with Malathion 25% w.d.p. @ 2 gr./m2 was assessed in Rameshwaram Island, Tamil Nadu. Monitoring of entomological and parasitological indices revealed that due to deltamethrin spray malaria transmission could be effectively interrupted and a significant reduction in malaria cases was achieved. P. falciparum cases also showed a significant reduction whereas in the comparison malathion areas reduction in malaria cases or in pf cases was not recorded.

Résumé

Villages in South Arcot and Tirunelveli districts with high incidence of Japanese Encephalitis were selected for the study of insecticidal resistance to vectors. Culex vishnui and Anopheles hyrcanus group were found to be resistant to DDT (4 per cent for 60 min. exposure) and dieldrin (0.4 per cent for 60 min. exposure) but susceptible to Malathion (5 per cent for 60 min. exposure). So far, this is perhaps the first report of Anopheles hyrcanus group resistant to DDT and dieldrin to be reported from this area. The resistance may be due to extensive use of DDT and HCH for agricultural purposes.
