摘要
通过接触法和摄入法测定了毒死蜱和甲氰菊酯对蜜蜂的毒性。结果表明,毒死蜱和甲氰菊酯对蜜蜂的接触毒性(24hLD50)分别为0.1634μg/蜂和0.0501μg/蜂,胃毒毒性(24hLC50)分别为0.6406mg/L和7.8261mg/L。根据Atkins毒性等级划分标准,毒死蜱和甲氰菊酯对蜜蜂的毒性均为高毒,应禁止在蜜蜂活动区域使用。
Toxicity of chlorpyrifos and fenpropathrin to bee (Apis mellifera L.) was tested by contact method and food intake method. Safety evaluation was also conducted. The results showed that LD50(24) by contact method for chlorpyrifos was 0.1634ìg/bee, for fenpropathrin was 0.0501ìg/bee; and LC50(24h) by food intake method for chlorpyrifos was 0.6406mg/L, for fenpropathrin was 7.8261mg/L. Therefor, chlorpyrifos and fenpropathrin are highly toxic to bee (Apis mellifera L.), and should be inhibited from using in bee areas .
