【摘要】 长尾小蜂是属于膜翅目Hymenoptera小蜂总科Chalcidoidea长尾小蜂科Torymidae的昆虫的总称,它们中既有寄生性的种类,也有植食性的种类。寄生性种类大多是森林、经济林上重要害虫(如松毛虫、舞毒蛾)的天敌,对害虫种群发生数量有显著的控制作用,有可能被利用于森林、经济林害虫的防治;植食性种类有许多在林木种子内取食危害,大大降低了造林用种子的发芽率,同时还因为它们一生中大部分时间生活在种子内部,可能随造林用种子的调运而传播蔓延,因此带来检疫上的问题。美国和日本对此已有教训。本研究对中国长小蜂科常见属进行了全面、系统的分类整理,检查研究了浙江大学应用昆虫研究所多年来积累下来的2000多号标本,标本主要来自全国20个省、直辖市。本论文共记叙了我国长尾小蜂科3个属(大痣小蜂属Megastigmus Dalman, 1829除外)41个种—包括30个新种,11个文献已有记录种。文中作者对实际研究过的30个新种,作了比较详细的形态描述,并列有该种的分布、生物学、有关文献、鉴别特征或与近缘种的区别等。本文编制了中国长尾小蜂科常见属的分属检索表,每个属编制有分种检索表。新种皆有分类特征图,所有标本均保存于浙江大学农业与生物技术学院应用昆虫研究所。本文在概述部分按中国动物志的编写规格要求介绍了中国长尾小蜂科的研究历史和分类沿革、形态特征、生物学特征和地理分布。更多还原

【Abstract】 Torymidae is a middling family of Chalcidoidae, Hymenoptera. Parasitic and phytophagous wasp of the family Torymidae are foumd throughout the world. Most of the parasitic wasps are important natural enemies on various pests of forest. They can control the pest distinctly. Strictly phytophagous species of Torymidae are seed-feeders, which bring some quarantine proplem with the seeds transport. The seeds which are infected by them will not burgeon. In the research, known Torymidae species of China were systematically and thoroughly studied, totally 2000 speciemens examined were from Institute of Applied Entomology, Zhejiang University which has been collected for many years. Specimens collected from 20 provinces of China. 3 genera and 41 species were reported. 30 new species were actually examined in this research, and particularly decrypted. Characters, host records, distribution biology and references of species were given. Specimens of new species deposited in Institute of Applied Entomology, College of Agriculture and Biotechnology, Zhejiang University; new species were morphologically described and distinguished with similar species; Keys to genera, species were given, figures for new species. The study history, taxonomy, characters biological notes and geological distribution of Torymidae were also given in the introduction.The new species treated in this paper are as follows.Monodontomerini Monodontomerus Westwood. 1833Monodontomerus xui, sp. nov.Podagrionini Podagrion Spinola, 1811Podagrion confusum, sp. nov.
