阜南县位于淮北平原,在农业生产中棉花占有相当重要的地位。历年来棉虫的为害是棉花生产的主要威胁。多年来,依靠化学农药进行棉虫防治,产生了一些如污染环境、杀伤有益天敌、害虫抗药性增强、防效低、经济效果差等不良后果。因此,研究、试验、总结出一套经济、安全、有效的棉虫综合防治措施,是贫下中农的迫切愿望,也是当前植保科研工作中急需解决的新课题。 Funan County is located in Huaibei Plain, where cotton plays an important role in agricultural production. The damage of cotton insects over the years is a major threat to cotton production. Over the years, relying on chemical pesticides for the control of cotton insects has produced some adverse consequences such as environmental pollution, beneficial natural killer, increased resistance to pests, low efficacy and poor economic results. Therefore, it is an urgent desire for the poor peasants and middle peasants to study, test and conclude an economic, safe and effective comprehensive control measure against insects and insects. It is also a new topic urgently needed to be solved in the research work of plant protection.
