Isolation, characterization, in-vitro antibiotic susceptibility and pesticide tolerance of gut bacteria from rice hispa, Dicladispa armigera (Olivier)
Abstract
Whole gut was dissected from rice hispa Dicladispa armigera (Olivier) and the bacteria belonging to genera Bacillus, Proteus, Micrococcus, Pseudomonas and Klebsiella isolated and identified. All the bacterial strains were found resistant to penicillin G, ampicillin, methicillin and cephalexin but sensitive to streptomycin, ciprofloxacin, rifampicin and vancomycin. The bacteria could also resist 1000 ppm endosulfan and to some extent chlorpyriphos and quinalphos. The GLC analysis showed that all the gut bacteria had the potentiality to degrade endosulfan.
