摘要
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。
Angoumois grain moth ( Sitotroga cerealella ) usually divelops 5 genirations each year in Huaibei District. The pupation and emergence peaks of overwinter generation were tidy and concise. Which led to the egg peak of the first generation Concentratally occurred in wheat field. Egg peak of the first generation occurred coincidentally with flowering and early filling stage of wheat. We may use calendar stage and air temperature to accurately forecast of Angoumois grain moth occurrence, Seleitive application of high effective chemical and IPM stratigies can keep Angoumois grain moth in check for the whole year forecast.
