小麦吸浆虫主要有两种:麦红吸浆虫和麦黄吸浆虫。这两种吸浆虫分布很广,几乎遍及小麦产区。河北省以南部为中心向北部漫延。主要危害小麦花器和籽实。魏县主要是麦红吸浆虫。 红吸浆虫发生条件与气候有关,幼虫耐低温不耐高温,越冬幼虫在土温10℃以上时才破茧活动,15℃化蛹,20℃成虫大量羽化,成虫产卵期气候干燥会造成大量死亡。另外也与小麦品种有关。 5月上旬小麦进入抽穗扬花期,小麦吸浆虫也随之进入成虫期。由于一部分乡村在蛹期防治上措施不当,致使麦田残虫量较高,给夏季小麦丰产丰收带来隐患。
There are two main types of wheat midge, Microglobulin and midge. The two inhalers are widely distributed, almost throughout the wheat producing areas. Hebei Province to the north as the center of the spread. The main harm to wheat flower and seed. Wei County is mainly Midge. Cryptomelata occurrence conditions and climate-related, larvae are not resistant to high temperature low temperature, overwintering larvae in the soil temperature above 10 ℃ only cocoon activity, pupation at 15 ℃, 20 ℃ adults a large number of emergence, adult spawning period of dry weather can cause a large number of death . Also related to wheat varieties. In early May, wheat entered the flowering and flowering stage, the midge of wheat also entered adult stage. As a result of improper measures in prevention and control of pupal stage in some villages, the higher amount of residual rodents in wheat fields brought hidden dangers to the harvest of summer wheat.
