摘　　要：在小试管和马尾松木段内,用松褐天牛幼虫分别培育川硬皮肿腿蜂。采用Y型嗅觉仪测定培育后各代川硬皮肿腿蜂对松褐天牛的选择性的变化,结果表明,经过培育,各代川硬皮肿腿蜂对松褐天牛幼虫的选择性有不同程度提高。本研究还利用扫描电镜对培育后各代川硬皮肿腿蜂的触角感觉器超微形态进行了观察,发现肿腿蜂触角上的板状感器和坛状感器的形状和数量在不同代间有明显的变化。Reared by Monochamus alternatus larvae in small test tube and twigs of Pinus massoniana,the host-selectivity of several generations of Sclerodermus sichuanensis was studied.The Y-tube olfactometer and scanning electron microscope were used to detect the diversification of the host-selectivity.The results showed that the host-selectivity of reared generations could be improved with varying degrees.The antennal sensilla of Sclerodermus sichuanensis was observed through electron microscope,which showed that the ultrastructure of sensilla placoclea and sensilla ampullaceal of some adults were deformed.
