麦蛾在淮北地区1a发生5代,只有越冬代的化蛹、羽化高峰期短而整齐,使发生在小麦大田生长期的一代麦蛾的落卵高峰集中,且此时正值小麦扬花至灌浆初期。利用期距法和气温预报可准确预报发生期,选用高效农药进行统一防治,可达到控制全年为害的目的。
In the Huaibei area, larvae developed for 5 generations. Only the pupal pupal overwintering generation had a short and sharp peak emergence period, which resulted in the concentration of the highest larvae in the first generation of T. molitor in the wheat field growth period, Early. The use of long-range method and temperature forecasting can accurately predict the occurrence of high-performance pesticides for the prevention and control, can achieve the purpose of controlling pests throughout the year.
