Abstract:

【Objective】 To screen effective pesticides for the control of Acalitus phloeocoptes Nalepa. 【Methods】 By selecting 5 single agents and 5 compound agents for field pesticide screening research. Two field efficacy evaluations were conducted on the control of Acalitus phloeocoptes Nalepa using single and compound pesticides. At 3, 6, 9, 12, and 15 days after treatment, the insect population density was investigated, the rate of insect population reduction and control effect were calculated, and green and efficient drugs and the optimal concentration were selected. 【Results】 The 1,500 fold solution of 15% avermectin·spirochete (SC) had a good control effect on adult mites, with a control effect of 86.24% after 15 days of treatment. The second was the 2,000-fold solution of 5% avermectin (EC)+30% imidacloprid (SC) complex, and the 1,500-fold solution of 20% imidacloprid (SL). The control effect on adult mites and eggs was good, with a control effect of 71.95% and 79.51% after 15 days of treatment, respectively. The sustained efficacy was stable in the later stage. The 2,500-fold solution of 5% avermectin (EC) had the worst control effect on adult mites, significantly lower than the effective drug (P<0.05). The 2,500-fold solution of 15% avermectin (SC) had the worst egg control effect, with negative results at 6 and 12 days after treatment, followed by a 2,000-fold solution of 200 g/L amitraz, with no more than 33% post treatment effect. The prevention effect of other drug concentration treatments is between the two mentioned above.【Conclusion】 The 15% avermectin spirochete (SC) 1,500 fold solution, 30% avermectin triadimefon (SC) 2,000 fold solution, and 20% imidacloprid (SL) 1,500 and 2,000 fold solution have good control effects on the Acalitus phloeocoptes Nalepa, and can be rotated for use in the field.

摘要:

【目的】筛选防治梅下毛瘿螨的有效药剂。【方法】选取5种单剂及5种复配剂筛选田间药剂。采用单剂及复配药剂2次开展防治梅下毛瘿螨田间药效评价。药后3、6、9、12和15 d分别调查虫口密度,计算虫口减退率及防效,筛选出绿色高效的药剂及最佳浓度。【结果】15%阿维·螺虫酯(SC)1 500倍液对成螨防效好,药后15 d防效为86.24%,其次是5%阿维菌素(EC)+30%乙唑螨腈(SC)复配剂 2 000倍液、20%吡虫啉(SL)1 500倍液对成螨、卵的防效较好,药后15 d防效分别为71.95%、79.51%,后期持效性稳定。5%阿维菌素(EC)2 500倍液对成螨防效最差,显著低于防效好的药剂(P<0.05)。15%阿维·螺虫酯(SC)2 500倍液对卵防效最差,药后6、12 d防效呈负值,其次200 g/L双甲脒2 000倍液,药后防效均不超过33%。其他药剂浓度处理的防效介于上述二者之间。【结论】15%阿维·螺虫酯(SC)1 500倍液、30%阿维·乙唑螨腈(SC)2 000倍液和20%吡虫啉(SL)1 500、2 000倍液对梅下毛瘿螨的防效较好,可在田间轮换使用。
