摘要
通过田间采梢、室内镜下查卵和饲养观察,初步获得假眼小绿叶蝉Empoasca vitis Gthe卵寄生蜂2种,分别隶属于三棒缨小蜂属Stethynium sp.和裂骨缨小蜂属Schizophragma sp.,其中三棒缨小蜂属Stethyniumsp.是优势种。2种缨小蜂的寄生动态调查结果显示,除8月和12月寄生率较低外,其它月份的自然寄生率都在30%以上,特别是10-11月寄生率最高达65%,对小绿叶蝉的虫口数量具有重要控制作用,值得进一步研究和保护利用。
By dissecting the eggs of the small green leathopper, Empoasca vitis Goethe, collected from tea shoots and by rearing the parasitized eggs in laboratory, we found 2 species (Stethynium sp. and Schizophragma sp. ) of Mymaridae in Fujian. Among the 2 parasitoid species collected, Stethynium sp. was the dominant species. The egg parasitism rates of the two species, except in August and December, were all above 30%, with a highest peak(up to 65% ) during October to November. These mymarid parasitoids were important for controlling the small green leathopper and deserved to be protected and further utilized.
