Malaria transmission during post-spray period of pirimiphos-methyl in Arunachal Pradesh.
Observations made for a period of four years from 1985 to 1988 on post-spray impact of pirimiphos-methyl (25 per cent Wp) on malaria vectors in Tirap district of Arunachal Pradesh showed that a low density (0.0 to 0.02 PMH) of Anopheles dirus was maintained in the areas sprayed with the insecticide at the dosages of 1 and 2 g/m2 from 1981 to 1984. The post-spray data (1985 to 1988) showed a reduction of 62.5 to 62.8 per cent in SPR, 55.6 to 64.7 per cent in SRF and 72.3 to 75.5 per cent decline in API as compared to baseline data of 1980 in areas sprayed with pirimiphos methyl.
