笔者于2003年至2011年对新疆博州地区棉蚜进行了系统调查。调查发现,自2003年棉蚜暴发为害后,棉田棉蚜由秋蚜为害为主转变为以伏蚜为害为主,秋蚜发生为害减轻;如果棉蚜为害高峰期提前至6月中旬前后,则造成为害损失重。6~7月时晴时雨天气过程利于棉蚜发生,而7月底有少量降雨过程就会导致棉蚜种群数量迅速消退。做好棉蚜系统调查工作,及时预报棉蚜发生高峰期,抓好点片防治及联防统治工作,可有效防控棉蚜发生为害。
From 2003 to 2011, the author conducted a systematic investigation of cotton aphids in Bozhou, Xinjiang. The survey found that since 2003 cotton aphid outbreaks, the cotton aphid by the fall aphids mainly to change to aphid-based harm, aphids occurred to reduce harm; if the peak of aphid infestation early before mid-June, then Damage caused heavy damage. From June to July when sunny, rainy weather aided the occurrence of cotton aphid, and a small amount of rainfall at the end of July caused the number of cotton aphid population to recede rapidly. Do a good job of cotton aphid system investigation work, timely prediction of cotton aphid peak occurrence, do a good job of prevention and control and prevention and control joint work, which can effectively prevent and control cotton aphid harm.
