【摘要】：为明确草莓蚜虫防治用药对蜜蜂的影响,按照《化学农药环境安全评价试验准则》和《化学品测试方法》要求测定了20%啶虫脒SP、10%氟啶虫酰胺WG和22%氟啶虫胺腈SC对意大利蜜蜂(Apis mellifera L.)的急性毒性,并采用危害商值(HQ)法进行了风险评价。急性毒性结果显示:20%啶虫脒SP、10%氟啶虫酰胺WG和22%氟啶虫胺腈SC对蜜蜂的急性经口毒性试验结果(48 h-LD50值)分别为4.47μg a.i.·蜂~(-1)、11.2μg a.i.·蜂~(-1)和0.0601μg a.i.·蜂~(-1),对蜜蜂的急性接触毒性试验结果(48 hLD50值)分别为11.0μg a.i.·蜂~(-1)、13.9μg a.i.·蜂~(-1)和0.643μg a.i.·蜂~(-1)。按《化学农药环境安全评价试验准则》中毒性等级划分标准,20%啶虫脒SP、10%氟啶虫酰胺WG和22%氟啶虫胺腈SC对蜜蜂的毒性等级分别为中毒、低毒和高毒。风险评价结果表明,22%氟啶虫胺腈SC对蜜蜂存在中等风险(HQ值为1 622),20%啶虫脒SP和10%氟啶虫酰胺WG对蜜蜂的风险为低风险,其HQ值分别为40.3和6.70。因此,草莓生产中可优先选用10%氟啶虫酰胺WG来防治蚜虫,20%啶虫脒SP次之。而使用22%氟啶虫胺腈SC时,应注意采取措施降低其对蜜蜂的毒性风险,以免造成危害。
[Abstract]:In order to clarify the effect of strawberry aphids on honeybee, According to the requirements of chemical pesticide environmental safety assessment test guidelines and chemical test methods, 20% acetamiprid SPX 10% flutamide WG and 22% fluazidonitrile SC against Apis mellifera L.were determined. The risk was evaluated by hazard quotient (HQ) method. The acute toxicity results showed that the acute oral toxicity test results of 10% fluazinamide WG and 22% flutamide SC to bees were 4.47 渭 g / L and 0.0601 渭 g / kg, respectively, and the acute exposure toxicity to bees was 4.47 渭 g a.i. and 0.0601 渭 g / g, respectively. The acute toxicity of Acetamiprid 10% fluazinamide WG and 22% fluazinonitrile SC was 4.47 渭 g a.i. i-1 and 0.0601 渭 g, respectively. The results of the experiment showed that the values of 48 hLD50 were 11.0 渭 g a.i. 1, 13.9 渭 g, and 0.643 渭 g, respectively. According to the criteria of environmental safety assessment of chemical pesticides, the toxic grades of 20% acetamiprid 10% flutamide WG and 22% flutamide SC to honeybee were toxic, low toxicity and high toxicity, respectively. The results of risk evaluation showed that 22% flupronil SC had a moderate risk to bees with HQ values of 1 622 2% acetamidine SP and 10% flutamide WG as low risk, with HQ values of 40.3 and 6.70, respectively. Therefore, 10% fludiazolamide WG was preferred to control aphids 20% acetamidine SP in strawberry production. However, when using 22% fluazonitrile SC, some measures should be taken to reduce the risk of toxicity to honeybees, so as to avoid harm.
