Impact of devaluation of Indian Currency
Abstract :
Larvicidal property of extracellular secondary metabolites of 64 actinomycetes isolated from soil samples of different natural and man-made habitats was tested against early third instar of Anopheles stephensi. Twenty three isolates of them showed positive larvicidal activity. Among the 23 isolates, four isolates of Streptomyces (A14, A21, A49, A63) and each one isolate of Micromonospora (A32) and Actinoplanes (A52) were found to be highly active against mosquito larvae with LC50 values ranging from 9 to 60ppm. Among them, the isolate of Streptomyces A21 was found to be a highly potential larvicidal agent An. Stephensi, having the lowest LV50 value of 9.20 ppm.
