五、习性防治小麦在储藏过程中,一旦发生了害虫或受害虫(麦蛾、玉米象、大谷盗和谷蠹等)危害,就要利用害虫的习性,采取相应的措施来预防和消灭它们。例如,发现麦蛾发生在粮堆外层,活动在空间,防治上应采取压盖密闭的方法。这种方法是针对麦蛾集聚粮面交尾产卵的特性,在第一代麦蛾成虫出现(即羽化)以前,及时将粮堆压盖密闭,使粮粒内羽化出来的成虫无法交尾产卵而死亡。因此,压盖密闭必须在第一代麦蛾羽化前完成。最好在每年早春2—3月进行。压盖物可 Fifth, the habit of prevention Wheat in the storage process, once the occurrence of pests or by pests (wheat moth, corn elephant, Ditian Pi and Gu Ye, etc.) hazards, it is necessary to use pests habits, take appropriate measures to prevent and eliminate them. For example, it was found that the moths occurred in the outer layer of food piles, activities in space, prevention and control should be adopted gland airtight method. This method is aimed at the moth gathering grain noodles spawning characteristics, in the first generation of adult moth moth occurrence (ie, emergence), the timely closure of the pile cover, so that the emergence of adults within the grains can not be cross-spawning And death. Therefore, gland closures must be completed before the emergence of the first generation of moths. The best February to March each year in early spring. Gland can be
