title: Impact of deltamethrin spraying on malaria transmission in Rameshwaram Island, Tamil Nadu State - India.
abstract: 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.
