在橡绿卷叶蛾的越冬卵上可以找到已经形成的幼虫。这些幼虫是在早放叶型橡树叶片开放时产生的。幼虫的成熟和破壳需要一定的春季热量,但究竟需要多少有效温度才能成熟,至今在书籍上尚未指出过。为了确定航空喷药的开始日期,作者于1956—1961年观察了橡绿卷叶蛾的发育过程;记录了大量幼 The larvae that have formed can be found on the overwintering eggs of Oak Leafworm. These larvae are produced when leaves of early-leaved oak leaves open. Larvae mature and broken shell need some spring calories, but exactly how much effective temperature to mature, so far in the books have not pointed out. In order to determine the start date of aerial spraying, the authors observed the developmental process of the leaf roller Weber; from 1956 to 1961; recorded a large number of young
