- 摘要:
- 为研究美国白蛾幼虫取食习性及对常见行道树寄主的嗜食性特征,本文利用法国梧桐、白蜡、垂柳、樱花、红叶李和白杨叶片作为饲喂寄主,通过室内饲养、生物统计、定点标记等方法研究了美国白蛾幼虫的取食选择性行为。结果表明:美国白蛾幼虫对不同寄主的取食习性没有明显差异,不同寄主饲养的幼虫对常见行道树的嗜食性之间不存在明显差异,可能与试验材料为初孵幼虫有关。美国白蛾幼虫对青岛地区常见行道树的嗜食行为说明该昆虫的取食方式具有一定的随机性,因此美国白蛾幼虫对环境应该具有很强的适应能力。
- Abstract:
- In order to study the feeding habits of white moth larvae and their feeding habits to common street tree hosts,the feeding selectivity of white moth larvae was studied by indoor rearing,biological statistics and fixed-point markers,using the leaves of Ficus alba,Baiwax,weeping willow,cherry blossom,plum and poplar as feeding hosts.The results showed that there was unobvious difference in feeding habits between different hosts,and there was unobvious difference in feeding habits between the larvae reared by different hosts on common street trees,which might be related to the experimental material being newly hatched larvae.The feeding habits of Hyphantria cunea larvae on common street trees in Qingdao indicate that the feeding patterns of the insects are random,so the Hyphantria cunea larvae should have strong adaptability to the environment.
