摘　　要：久单爪螯蜂Anion jurineanum Latreille在山东商河寄生旱柳广头叶蝉Macropsis matsudanis Cai et Wei、绿体广头叶蝉M．virescens（Fabricius）、柳小绿叶蝉Empoasca flavescens（Fabricius），在南京寄生大麻广头叶蝉Mcannabis Cai et wei，具有捕食和寄生的双重控制能力。文章首次记述其幼期形态特征、生活史、生活习性等。该虫在山东商河1a发生1代，以4龄老熟幼虫在地面土茧内越夏越冬。翌年4月下旬成虫羽化，捕捉寄主若虫补充营养。成虫产卵于旱柳广头叶蝉3—5龄若虫中足或后足基部的胸部组织内。卵历期平均72．8h，幼虫孵化至脱囊平均历时149h，产卵至脱囊平均历时232h，蛹期平均16．1d。对旱柳广头叶蝉的寄生率24．3％～60．3％。Anteon jurineanum Latreille, parasitizing Macropsis matsudanis ,M. virescens , Empoasca flavescens in Shanghe of Shandong Province and M. cannabis in Nanjing, had both the predation and parasitic capacity. Its larval morphology, life history and habits were first described. Anteon jurineanum had one generation a year in Shanghe. It overwintered and oversummered as matured larva in the 4th instar in cocoon on the ground. The adult emerged in the last ten days of April the next year and preyed on the nymphs of the host for nutrition. It laid eggs in thoracic part in the base of midlegs and hindlegs of Macropsis matsudanis nymphs between the 3rd and 5th instars. The average egg stage lasted 72. 8 hours,the average duration between hatching and excystation of the larva was 149 hours and average pupal stage was 16. 1 d. The parasitization on Macropsis matsudanis was 24.3% -60. 3%.
