棉红铃虫是棉花蕾铃期的常发性害虫,对产量和品质危害很大。因现行的防治标准过严,生产实践上难以照办,而导致防治成本过高,每年用于此虫的农药费用约占防治棉花病虫害农药费用中的一半左右。为提高棉红铃虫的预测预报及综合防治水平,降低防治成本,我们在全国植保总站的指导下,于1982—1985年,按照统一方案,进行了棉红铃虫危害损失和防治指标研究。现将结果报告如下:
Cotton bollworm is a common pest in cotton boll stage, which is harmful to yield and quality. Due to the current strict control standards, production is difficult to handle in practice, resulting in prevention and treatment costs are too high, the annual cost of pesticides for this pest about prevention and control of cotton pests and pesticides in about half of the cost. In order to improve the prediction and comprehensive prevention and control of Helicoverpa armigera and to reduce the cost of prevention and treatment, under the guidance of the National Plant Protection Station, we conducted a study on the hazard losses and prevention and control of Helicoverpa armigera from 1982 to 1985 according to a unified plan. The results reported below:
