氟啶虫胺腈等11种杀虫剂对瓜蚜的毒力及协同增效作用
|
摘要
为探寻防治瓜蚜的高效协同增效药剂组合,采用叶片带虫浸渍法测定了氟啶虫胺腈等11种杀虫剂对瓜蚜的毒力。结果表明:处理后24 h,氟啶虫胺腈对瓜蚜的毒力最高,吡蚜酮最低,LC_(50)值分别为10.15和369.63 mg/L;48 h时依然是氟啶虫胺腈毒力最高,而高效氯氟氰菊酯最低,LC_(50)值分别为2.35和117.57 mg/L。在此基础上进行协同增效药剂筛选,结果表明:按质量比计,氟啶虫酰胺与吡蚜酮1:1、氟吡呋喃酮与吡蚜酮1:5、氟啶虫胺腈与吡蚜酮1:3、氟吡呋喃酮与高效氯氟氰菊酯1:5、氟啶虫胺腈与高效氯氟氰菊酯1:5几种组合的增效作用显著,共毒系数分别达1 271、820、561、1 277和478。研究结果可为田间瓜蚜的高效化学防治提供科学依据。
In order to develop high-efficiency synergistic insecticide combinations against Aphis gossypii Glover, the toxicities of sulfoxaflor and other ten insecticides against A. gossypii were determined by the leaf dipping method. The results showed that among all the eleven insecticides tested,sulfoxaflor showed the highest toxicity against A. gossypii, and pymetrozine exhibited the lowest toxicity 24 h after the treatment, with the LC_(50) values of 10.15 mg/L and 369.63 mg/L, respectively.When the results obtained after 48 h were considered, sulfoxaflor was still the highest effective insecticide to A. gossypii, and the lowest toxic insecticide became lambda-cyhalothrin, with the LC_(50) values of 2.35 mg/L and 117.57 mg/L, respectively. Based on these results, the co-toxicities of different insecticides combinations were determined, and the following insecticides combinations showed obvious synergism against the aphid: flunicotamid plus pymetrozine(1 : 1), flupyradifurone plus pymetrozine(1 : 5), sulfoxaflor plus pymetrozine(1 : 3), flupyradifurone plus lambda-cyhalothrin(1 :5), and sulfoxaflor plus lambda-cyhalothrin(1 : 5). And the co-toxicity coefficients(CTC) were 1 271,820, 561, 1 277 and 478, respectively. These results have provided a scientific basis for the efficient chemical control of A. gossypii.
