据初步调查,武昌郊区被六索线虫Hexamermis spp.寄生的蔬菜害虫有:小地老彪Agrotis ypsilon、菜粉蝶Pieris rapae、甜菜夜蛾Laphygma exigua、斜纹夜蛾Prodenia Litura和烟夜蛾Heliotkis assulta;前四种的寄生率分别为41.4%,34.0%,10.8%,5.7%;经鉴定,六索线虫共有5种,即:白色六索线虫中华亚种H.albicans sinensis、菜粉蝶六索线虫H.pieris、地老虎六索线虫H.agrotis、太湖六索线虫H.taihuensis,另一种种名待定Hexamermis sp.,前者为优势种,依次两种为常见种,后者为稀见种,六索线虫与害虫幼虫间无寄生专一性,可交叉感染。
According to the preliminary investigation, the vegetable pests parasitized by the hexamermis spp. In the suburbs of Wuchang are: Agrotis ypsilon, Pieris rapae, Laphygma exigua, Prodenia Litura and Heliotkis assulta; The parasitism rates of the four species were 41.4%, 34.0%, 10.8% and 5.7%, respectively. There were five species of C. elegans identified as H.albicans sinensis and H. viridis H. pieris, H. tigerii, H.taihuensis and Hexamermis sp., the former being the dominant species, followed by two species of common species, the latter being rare species, No parasitic specificity with pest larvae, cross-infection.
