摘要:

研究了秦岭林区华山松大小蠹( Dendroctonus armandi) 带菌部位及贮菌器结构,结果表明:华山松大小蠹成虫具有前胸背板体壁凹陷和刺毛构成的贮菌器,用于携带和传播真菌,其所携带真菌种类以穿孔细帚霉Leptographium terebrantis 和小线嘴壳Ophiostoma minus 为主,以真菌孢子为唯一携带方式,并在成虫入侵健康寄主华山松时将携带真菌孢子接种于华山松木质部。华山松大小蠹消化道内不具有含菌细胞和特化的带菌结构,消化道内存在的真菌也没有菌丝发育形成的附着孢或吸盘结构,使真菌不能被有效地贮存或携带于华山松大小蠹成虫消化道内,从而达到对真菌的有效传播和导致华山松大小蠹与真菌共生的联系。

Abstract:

The carrying microorganism position and the structure of mycangium of Dendroctonus armandi Tsai et Li, the most destructive bark beetle in Qinling and Bashan Mountains were studied. The results showed that the mycangia of the adult D. armandi consisted of the pronotal intergumentary cavities and spines, the spores of Leptographium terebrantis and \%Ophiostoma minus\% were the main spores carried by the mycangia of D. armandi, and they were inoculated into xylem of the host trees, while the beetle infested healthy host tree. Because there were no specialized mycetocytes and carried fungi structure in endobody of D. armandi, any hyphae specialized appressorium or sucher structure in the fungi, the fungi were attached to the alimentary canal of D. armandi, and the alimentary canal of D. armandi was not the stocked and transported fungi spores areas. D. armandi was not depended on the alimentary canal to carry and transport the fungi.
