摘要
植食性昆虫主要利用嗅觉、味觉、视觉和触觉等对寄主植物进行选择,而植物挥发物是引导植食性昆虫寄主定向行为的主要因素。利用"Y"型嗅觉仪测试康定虫草蝠蛾Hepialus armoricanus二龄幼虫对适生地的几种植物材料的嗅觉反应;并用欧式距离和Q型聚类法对供试植物进行相似性分析和聚类分析。结果表明:蝠蛾幼虫对几种植物材料表现出强弱不同的趋性反应;根据植物的相似性可将供试植物分为4类,且同一类植物引导蝠蛾幼虫产生相似的嗅觉反应。
Phytophagous insects select host plant mainly by smell,taste,vision and touch,while plant volatiles are the main factors guiding the directional behavior of the phytophagous insects.To test the olfactory response of the Kangding cordyceps Hepialus 2nd-instar larva to several plants in the suitable habitat,using the Y-shaped olfactometer,and analyze the similarity and clustering of the tested plants applying the Euclidean distance and Q-type clustering method.As a result,Hepialus larvae show different intensities of the chemotactic response towards several plant materials;according to the similarity of the plants we divided them into four kinds of plants,and the each certain kind of plants guide Hepialus larvae produce specific olfactory response.
