为了明确褐背小萤叶甲与寄主植物的关系 ,对其寄主范围进行了测定。结果表明 :褐背小萤叶甲嗜食蓼科植物 ,属于寡食性昆虫。强迫取食试验发现 :该虫在草莓上虽能完成世代发育 ,但草莓对成虫刺激产卵等选择性差 ,产卵量少 ,幼虫发育慢。而在蓼科杂草上则相反 ,世代多 ,繁殖力强 ,群集发生与为害 ,在农田生态系中 ,对自然控制蓼科杂草起到重要作用 ,其安全性有待于进一步观察和研究
In order to clarify the relationship between Monochamus alternatus and host plants, its host range was determined. The results showed that: Penicillium dorsalis petals Polygonaceae plants, belonging to the oligivore insects. Forced feeding test found that although the insects on strawberry can complete the development of the generation, but strawberries on the adults to stimulate the spawning, such as poor selectivity, fecundity, larvae develop slowly. On the contrary, the weeds in Polygonaceae have the opposite genera, which have many generations, strong fertility and cluster occurrence and damage. In farmland ecosystem, they play an important role in the natural control of Polygonaceae weeds, and their safety needs to be further observed and studied
