Abstract: [Objective] Chromaphis juglandicola Kaltenbach is an important pest in the production of walnut.This project aims to find new compounds to control it.[Method]Control effect evaluation of a new aphid alarm pheromone analog 12.5; CAU1204 Microemulsion against Chromaphis juglandicola Kaltenbach was studied by pesticide spraying method.[Result]It was suggested that the spraying of 12.5;CAU1204 Microemulsion was safe to walnut and a significant dosage response was observed in the tested dosage range of 7.5 g·ai / hm2-60 g·ai / hm2, and the efficacy ascended along with the dosage increasing.The best effect was obtained in the dosage of 60 g·ai / hm2, and the effect reached up to 74; after the application of 7 d and 9 d.There were no significant differences between the dosages of 30 g·ai / hm2 and 60 g·ai / hm2.The efficacy was significantly increased by 38.83; in the treatment of combined use of 15 g·ai / hm2 CAU1204 and 45 g·ai / hm2 imidacloprid to compare with the same dosage of single CAU1204 treatment.[Conclusion]The new compound CAU1204 Microemulsion showed fine effect to Chromaphis juglandicola Kaltenbach, and the combined use with imidacloprid can significantly enhance the control effect.

摘要： [目的]核桃黑斑蚜Chromaphis juglandicola Kaltenbach是核桃生产中的重要害虫之一,研究新型蚜虫报警信息素微乳剂对核桃黑斑蚜的田间药效,为防治核桃黑斑蚜提供新型农药.[方法]运用喷雾施药法,采用不同浓度处理的12.5; CAU1204蚜虫报警信息素微乳剂,对核桃黑斑蚜的田间药效评价.[结果]在7.5~60 g·ai / hm2供试的剂量范围内,12.5; CAU1204蚜虫报警信息素微乳剂对作物安全,并表现出显著的剂量效应,即随施药剂量的增加防效逐渐升高.60 g·ai / hm2剂量效果最好,持效期较长,在药后9 d防效仍然保持在74.21;.30与60 g·ai / hm2剂量与药效无显著性差异.12.5; CAU1204蚜虫报警信息素15 g·ai / hm2与70;吡虫啉水分散粒剂45 g·ai / hm2混用具有显著的增效作用,较等量的单剂处理增效38.83;,达显著性差异水平.[结论]新型12.5; CAU1204蚜虫报警信息素微乳剂,对核桃黑斑蚜有较好的防治效果,与吡虫啉混用可显著提高防效.
