对新疆南部阿拉尔地区棉铃虫的种群动态进行了分析,发现该棉区棉铃虫越冬代、1代蛾量较少,2代棉铃虫蛾量相对比较大,其峰值显著高于其他两代。分析连续月份之间棉铃虫的关系结果表明,棉铃虫蛾量在5月与6月月份间线性关系不显著,6月与7月、7月与8月、8月与翌年5月月份之间存在线性关系,建立了预测模型,可对棉铃虫成虫进行中长期数量预测。
The population dynamics of cotton bollworm (Helicoverpa armigera) in Alar area of southern Xinjiang was analyzed. The results showed that the bollworm population overwinter passage, the first generation of moth was less, the second generation of bollworm was relatively larger, the peak value was significantly higher than the other two generations. The analysis of the relationship between bollworm in successive months showed that there was no significant linear relationship between bollworm and moth in May and June, June and July, July and August, August and the following month in May The linear relationship was established and the prediction model was established to predict the long-term population of H. armigera.
