Accelerated degradation of carbaryl by acclimated bacterial isolates from Apis cerana Bees

摘要

Pesticide metabolism in microorganisms results in formation toxic and/or non-toxic products (Kearney et al., 1963). Stenerson (1965) first speculated upon the role of bacteria-influenced metabolism of DDT in resistant mosquitoes. Sharma and Nath (1996) showed adaptation to carbaryl of bacterial isolates form Apis cerana bees. Treatment of bees with these modified isolates resulted in decontamination of bees and enhanced tolerance to carbaryl. This paper reports carbaryl degradation by acclimated bacterial isolates in different media and discusses the effects of supplemented carbon sources on degradation rates.
