摘要
利用性诱剂测报技术,对河北省赵县梨区和顺平县桃区梨小食心虫的田间种群动态进行了调查研究。结果表明:梨小食心虫在赵县梨区和顺平县桃区1a发生4代,具有发生持续时间长、世代重叠等特性。应依据梨小食心虫田间种群动态特性,采取综合防治措施,以控制其发生和为害。
The field population dynamics of Grapholitha molesta Busck in pear orchard in Zhaoxian County and peach orchard in Shunping County were investigated by predicting with sex attractant.The results indicated that G.molesta occurred 4 generations a year.Long duration and overlapping generations were the main characters of this moth,which could be controlled effectively with the integrated prevent measures.
