| Abstract: | Ostrinia farnacalis including number of eggs laid,damage degree of spring corn from June to August of 2007 in Qinghuangdao were investigated.The results showed that follows under the condition of vegetable field interplanting corn.The occurrence of the Aisan corn borer was two generation in the whole year.And peak stage of eggs laid was respectively occurred in the middle of June and the end of July early August,meanwhile,numbers of eggs masses were reached 712 and 344 separately.Furthermore, the first gene... |
