棉红铃虫繁殖力强,成虫产卵、幼虫危害都比较隐蔽,防治适期往往难于掌握。目前对红铃虫的防治还缺少可供利用的生物因素,因此,药剂防治次数逐年增多,成本加大,影响棉农经济收益,破坏棉田生态平衡。针对这些问题,从1981年开始,我们就红铃虫田间种群消长以及影响种群消长的主要因素,虫花脱落及其对棉株座铃的影响,危害棉铃造成的经济损失等方面,结合新发展的高效低毒药剂进行了研究。根据几年 Cotton bollworm reproductive ability, adult spawning, larvae are more subtle hazards, prevention and treatment are often difficult to grasp the appropriate period. At present, there are still lack of available biological factors for the control of Red Bell Pepper. Therefore, the number of drug control increases year by year and the cost increases, affecting the economic benefits of cotton farmers and damaging the ecological balance of cotton fields. In response to these problems, we started from 1981, we population and growth of Red bollworm in the field and the impact of population growth and decline of the main factors, insects and flowers on cotton bolls affect the economic harm, etc., combined with the new development The high efficiency and low toxicity agents were studied.
