Fufenozide was a novel pesticide for the control of Lepidoptera pests, which highly toxic to silkworm. Fufenozide-contaminated soil samples were collected and bacteria that degrade fufenozide isolated screened by selective medium. The colony characteristics, cell characteristics degradation in different concentrations degrading studied. results indicated seven strains degradeing bacteria, named as DDH01, DDH03, DDH04, DDH05, DDH07 respectively, from contaminated with fufenozide. DDH02, DDH04 DDH05 gram-positive DDH06 gram-negative bacteria. All not spores, weeks flagella, rod-shaped had capsules, remaining five capsule. colonies formed on beef extract peptone medium plate milky white irregular edges, thinner lawn, smaller smooth surface. growth 7 significantly affected concentration fufenozide, grown range 0.00025 g/mL 1 10% suspension. DDH2 best among suspension
