1992年春季,在瓦房店市胜利乡新开垦的稻田中,由于低温冷害的影响,秧苗大面积枯死.与此同时,我们在拔出的秧苗根部发现了大量形状特殊的虫蛹,通过室内人工饲养羽化成虫后,鉴定是瓦房店市从未报道过的一种新的水稻害虫——稻水蝇蛆. In the spring of 1992, in newly reclaimed paddy fields in Shengli Township, Wafangdian City, the seedlings died on a large area due to the effects of chilling injury. Meanwhile, we found a large number of special pupae at the roots of the seedlings that we pulled out and passed indoor After the artificial breeding of adult females, the identification is a new rice pest that has never been reported in Wafangdian - rice water fly maggots.
