摘　　要：褐双距螯蜂Gonatopus rufoniger Olmi在山东商河、平阴寄生宽槽胫叶蝉Drabescus ogumaeMatsumura和凹缘菱纹叶蝉Hishimonus sellatus(Uhler)若虫及成虫,具有捕食和寄生的双重控制能力。本文首次记述了其各虫态的形态特征、生活史、生活习性等。在山东商河1年至少发生2代,以幼虫在茧内越冬。5月下旬至9月上旬均可见成虫,8月下旬幼虫开始在茧内越冬。成虫产卵于寄主若虫腹部各节侧面的节间膜上。第1代卵历期平均45.7 h,幼虫孵化至脱囊平均历时129 h,自卵被产下至脱囊平均历时151.5 h,幼虫脱囊至羽化21.1 d,蛹期平均12.3 d。Gonatopus rufoniger had been parastitized on nymphae and adults of Drabescus ogumae and Hishimonus sellatus,and taken double effects on controlling pests by virtue of predation and parasitism in Shanghe and Pingyin county, Shandong province. The characteristics of morphologic, life history and hab were described for the first time. The host had happened at least 2 generations per year in S its of each life stages hanghe country, and over - wintered in cocoons as larva. Adults had been emergenced from late May to early Sept.. The larva began to over- wintered in cocoons at late August. Adults oviposited on the lateral integument intersegmental membrane between abdominal sections of host nymphae. Each of average development periods such as egg of the first generation, larva from hatching to taking off capsule, stages from primiparous egg to taken off capsule of larva and from larva taken off capsule to adult emergence , and pupae was 45.7 h, 129 h, 151.5 h, 21.1 d, 12.3 d respectively.
