2002-2003年通过系统调查对江苏棉田烟粉虱种群动态规律及其控制技术进行研究。结果表明:扬州市郊区棉田,7月下旬始见烟粉虱成虫,8月中、下旬形成第1个成虫高峰,10月上旬成虫消失;丰县棉田,7月中旬始见烟粉虱成虫,8月中旬出现第1个成虫高峰,10月下旬随着气温的下降田间成虫逐渐消失。棉田烟粉虱虫口密度,江苏北部棉区高于中部棉区,转Bt基因棉田高于常规棉田。黄板对烟粉虱成虫有一定的诱集作用。阿维菌素与吡虫啉混剂、灭多威和氧化乐果对棉田烟粉虱种群有一定的控制作用,其9d的校正虫口减退率分别为82.32%、84.59%和80.03%。
From 2002 to 2003, the population dynamics of Bemisia tabaci (Gennadius) and its controlling techniques in Jiangsu cotton field were studied through systematic investigation. The results showed that adults of Bemisia tabaci in the suburbs of Yangzhou City were found in late July, the first adults were found in mid-August and late adults, adults disappeared in early October, adults of Bemisia tabaci in mid-July and 8 The first adult peak appeared in mid-month and the adult in the field gradually disappeared with the decrease of temperature in late October. The population density of B. tabaci in cotton fields was higher in northern Jiangsu than in central cotton, and higher in Bt cotton than in conventional cotton fields. Yellow board on Bemisia tabaci adults have some effect of trapping. Abamectin combined with imidacloprid, methomyl and omethoate had certain control effects on Bemisia tabaci (Bemisia tabaci) population. Their 9d calibration rates were 82.32%, 84.59% and 80.03%, respectively.
