中文摘要：

研究了银灰杨接种外生菌根真菌（Paxillus involutus）对食叶害虫杨扇舟蛾（Clostera anachoreta）生长发育的影响。结果表明,幼虫期取食菌根化杨树叶片,显著降低了低龄期幼虫（2龄和3龄）的头壳和体重并显著延长了幼虫的发育历期,但对高龄期幼虫以及蛹期和成虫期的各项发育指标均无显著影响。因此,菌根化杨树苗抑制了杨扇舟蛾幼虫的发育,幼虫发育历期的延长增加其被天敌昆虫捕食的风险。

英文摘要：

In this study, the development of Clostera anachoreta Fabricius was explored when larvae fed poplar foliage from seedlings either inoculated with ectomycorrhiza Paxillus involutus or the noninoculated counterpart. Our results indi significantly reduced and the poplar leaves. However, the e. in cated that the larval weight （2nd and 3rd instar） and head capsule width were larval period was obviously prolonged by feeding on ectomycorrhizal infected development of pupae （i. e. adult weight, oviposition and longevity） were host plant. Application of Pa：rillus involutus pupal weigh little influenced by t and pupal period） and the adults （i. the ectomycorrizal fungus inoculation rendered Clostera anachoreta larvae more susceptible to natural enemies.
