管涔林区靖远松叶蜂生物学特性研究

笔者在山西省管涔山国有林管理局接官亭林场,对靖远松叶蜂的生物学特性进行了研究。结果表明,靖远松叶蜂在接官亭林场1 a发生1代,以茧内预蛹在枯枝落叶层下、杂草基部、苔草层下或其它地被物下越冬、越夏。5月上旬开始化蛹,下旬为化蛹盛期。成虫于5月下旬始见,6月中旬为盛期。卵与成虫相伴出现,6月中旬卵开始孵化,6月下旬至7月初为盛期。8月下旬至10月中旬,老熟幼虫相继坠地爬行寻觅适宜场所结茧。

Biological Characteristic Studies on Diprion jingyuanensis from Guancen Moutain Forest Region

The natural conditions,research object and method on Jieguanting Forest Farm were summarized.The results showed that the overwintering and oversummering of the Diprion jingyuanensis were as prepupa inside cocoon under litter layers,at the base of weeds,under carex layers and other ground covers.They begin to pupate from middle June,and are most abundant in late May.Adult worms were found first in late May,abundant in mid-June,coming forth with eggs,which begin to be incubated in mid-June.The peak stage of e...
