Abstract
A hut-scale trial of pyraclofos 50% EC applied as an indoor residual spray at 1 gm/sq m was carried out against malaria vectors. Anopheles fluviatilis and An. culicifacies in Kandhaguda village of Malkangiri district, Orissa. Bandhaguda village was kept as control. Pyraclofos was effective in reducing the vector density by 80-96% after 24 h of spray, but the density increased within three weeks. Parity rates were reduced only for three weeks as measured by diurnal indoor resting collection. Contact bioassays on mud wall showed pyraclofos has a residual life of only three weeks. No adverse effect was noticed among villagers or spraymen. Cockroaches were found to be very sensitive to this compound.
