Abstract: In order to control the harm of rape aphids effectively and select economical, effective and environmental friendly pesticides, the control effect and applied technology of the chosen pesticides were studied through safety measurement, field test and economic benefit analysis. The results showed that 70% imidacloprid WP, 5% diyaling DP, 50% nitenpyram SWG, 10% cyfluthrin EC, 1.8% abamectin EC and 2.5% beta-cypermethrin EC had high safety. Field test showed that those six pesticides could control the rape aphids, the control effects of 70% imidacloprid WP, 5% diyaling DP and 50% nitenpyram SWG after 10 days of the first application were 89.31%, 93.99% and 79.18%, while the control effects of the above three pesticides were 89.80%, 80.40%, and 86.35% after 10 days of the second application. The pesticides were beneficial to the growth and development of rape, and the economic trait of rape was better than that of CK. The analysis of economic benefits showed that the input-output ratio of the six pesticides was 1:6.53, and that of diyaling DP achieved 1:11.88. 5% diyaling DP, 70% imidacloprid WP and 50% nitenpyram SWG had better control effect on the rape aphids, meanwhile they were safe and economical, and could be used to control field rape aphids.
