原始语种摘要: Objective: Classical chemical control to mosquito is a preferable method. But it faces a problem for its increasing resistance against mosquito. To regulate the vector population as an alternative method, non-hazardous biocontrol methods would be the preeminent option to control mosquitoes. Objective of the present study is to examine the virulence of Bacillus sphaericus as an effective biocontrol agent against mosquitoes.Method: A strain of the bacteria Bacillus sphaericus was isolated from the gut of dead Culex quinquefasciatus Say, 1823 (Diptera: Culicidae) larva collected from submerged rice fields, Burdwan, West Bengal, India. The strain was characterized following standard methodologies.Result: The bacterial strain formed crystals, tolerated 4% NaCl, produced protease and sensitive...
