摘    要:松毛虫狭颊寄蝇Carcelia matsukarehaeShima是我国松毛虫Dendrolimus punctatus(Walke)的重要天敌。通过对被害马尾松(Pinus massonianaLamb.)针叶挥发性物质的提取、鉴定以及对松毛虫狭颊寄蝇的电生理测定,结果表明,大多数的挥发性物质,包括绿叶性挥发物以及松针特有的单萜、氧化单萜和倍半萜,对雌蝇均有明显的电生理活性,其中以顺-3-己烯-1-醇最高,长叶烯最低。雌蝇对4大类挥发性物质的平均相对触角电位反应值,以绿叶性挥发物为最高,其余依次为单萜、氧化单萜和倍半萜。

关 键 词:松毛虫狭颊寄蝇  马尾松  马尾松毛虫  触角电位  挥发性物质

Abstract:Carcelia matsukarehae Shima is the important natural enemy of pine caterpillars Dendrolimus punctatus(Walker) in China.The volatiles of pine Pinus massoniana Lamb.after damaged by pine caterpillars were collected and identified in the experiment.Electroantennograms from the female Carcelia matsukarehae Shima were recorded in response to the volatile compounds.Results showed that all volatile compounds but ( )-longifolene can elicit effective EAG responses to C.matsukarehae.The most effective antennal stimulants to C.matsukarehae was cis-3-Hexen-1-ol and the lowest was( )Longifolene during all the stimulus.The averaged EAG responses of the female flies to 4 different chemical classes showed that the green leaf volatiles elicited the largest EAG responses and hydrocarbon monoterpenes,oxygenated monoterpenes and sesquiterpenoids elicited subsequently some EAG responses to female flies.
Keywords:Carcelia matsukarehae  Pinus massoniana  Dendrolimus punctatus  electroantennogram  volatiles
