Field evaluation of a microgel droplet formulation of Bacillus sphaericus 1593M (Biocide-S) against Anopheles culicifacies and Anopheles subpictus in south India. The Southeast Asian Journal of Tropical Medicine and Public Health. 1993 Jun; 24(2): 363-8http://imsear.searo.who.int/handle/123456789/34083The Southeast Asian Journal of Tropical Medicine and Public Health.A microgel droplet formulation of Bacillus sphaericus 1593M (Biocide-S) was field tested at two different doses viz, 0.22 and 0.43 g/m2 in casuarina pits against a malarial vector Anopheles (Cellia) culicifacies Giles, and An. (Cel.) subpictus Grassi in coconut garden pits in the coastal areas of South India. Both doses significantly reduced the abundance of late instars and pupae of An. culicifacies for 3 and 5 weeks respectively. A significant reduction was recorded in the abundance of late instars and pupae of An. subpictus for 2 and 3 weeks respectively.engAerosolsAnimalsAnophelesBacillusBiopolymersIndiaLarvaParticle SizePest Control, Biological --methodsJournal Article
