桉树枝瘿姬小蜂Leptocybe invasa Fisher&La Salle是桉属(Eucalyptus)植物的重要枝叶害虫。自2007年在我国发现以来,对广西、海南及广东地区的桉树种植已造成严重危害。本文在野外调查的基础上,研究了海南和广东地区共5种桉树上桉树枝瘿姬小蜂的虫体大小、寿命及怀卵量。结果表明,桉树品种能够显著影响桉树枝瘿姬小蜂的虫体大小;用40%蜂蜜水进行补充营养时,不同寄主植物上桉树枝瘿姬小蜂雌成虫的寿命差异显著,而桉树枝瘿姬小蜂雄虫在不同寄主间无显著性差异;不同寄主植物上桉树枝瘿姬小蜂雌成虫的怀卵量不同,并且随着日龄的延长,其怀卵量呈现上升的趋势。
Leptocybe invasa Fisher & La Salle is an important foliar pest of the Eucalyptus plant. Since its discovery in China in 2007, it has caused serious damage to eucalyptus cultivation in Guangxi, Hainan and Guangdong. Based on the field investigation, this paper studied the body size, life span and egg-laying of five species of Eucalyptus on the eucalyptus in Hainan and Guangdong. The results showed that the eucalyptus varieties could significantly affect the size of the insect body of Eucalyptus, and the life span of the female adults of Eucalyptus Bursaphelenchus on different host plants was significantly different when supplemented with 40% honey water, There was no significant difference between male and female. The fecundity of female adults of Eucalyptus and Bombyx mandarinae on different host plants were different, and their fecundity showed an increasing trend with the increasing of age.
