摘要/Abstract

摘要：研究了靖远松叶蜂各虫态的生物学特性及其天敌种类.结果表明：1998年，成虫有2个明显的羽化高峰，分别在6月中旬和7月中旬；孤雌生殖与两性生殖的繁殖力没有显著差异；卵的发育起点温度为14.92±2.3 ℃，自然变温下有效积温为81.93±33.3 d·℃；幼雌虫共有7个虫龄；低虫口密度下，幼虫群团为聚集分布；雌蛹历期显著长于雄蛹；各虫态天敌种类较多，以幼虫期NPV病毒控制靖远松叶蜂最为有效.

Abstract: The behavior of D. jingyuanensis in each life stage including adult,egg,larva,prepupa and pupa was observed and described in detail and its natural enemy species were recorded.Studies showed that there were two climax which located the second ten-day of June and the second ten-day of July in the pine sawfly emergence in 1998.The reproduction rate difference between parthenogenesis and gamogenesis was not distict.Egg of developmental threshold was 14.92±2.3 ℃ and its effective accumulated temperature was 81.93±33.3 d·℃.Larva group took on aggregation distribution during low-density period.In outbreak of D. jingyuanensis,79 percent of cocoon was preyed by its natural enemies.The developmental time of female pupae was remarkably longer than male pupae.Maybe virus(NPV)infecting larva played an important role in controlling the sawfly population.

Key words: Diprion jingyuanensis；bionomics；natural enemy species, emergence dynamics
