摘要
通过测定5亿PIB/g甜菜夜蛾多角体病毒SC、30%茶皂素AS、1×1011个/g枯草芽孢杆菌WP 3种生物农药对蜜蜂、鹌鹑、斑马鱼和家蚕的急性毒性,对其进行环境安全评价。结果表明,5亿PIB/g甜菜夜蛾多角体病毒SC和1×1011个/g枯草芽孢杆菌WP对蜜蜂、鹌鹑、斑马鱼和家蚕的LD50或LC50均高于检测上限,为低毒级农药;30%茶皂素AS对蜜蜂、鹌鹑和斑马鱼为低毒级,对家蚕的LC50(96 h)为114 a.i.mg/L,为中毒级。试验可为这3种生物农药的合理使用提供科学依据。
The acute toxicity of 3 bio-pesticides including 5 hundred million PIB/g beet armyworm Polyhedrosis Virus SC,30％ tea saponin AS and 1×1011 Bacillus subtilis per gram on bee,partridge,zebra fish and silkworm were evaluated.The experiment environment was evaluated.The results showed that the LC50 or LD50 of 5 hundred million PIB/g beet armyworm Polyhedrosis Virus SC and 1×1011 Bacillus subtilis on bee,partridge,zebra fish and silkwor were higher than the highest detection limit.30％ tea saponin AS had low toxicity on bee,partridge and zebra fish,but had moderate toxicity of 114 mg/L of LC50（96h） on silkworm.The experiment would provide evidence for proper use of the bio-pesticides.
