双语推荐：白蜡吉丁肿腿蜂

选用4种肿腿蜂（管氏肿腿蜂、白蜡吉丁肿腿蜂、落叶松吉丁肿腿蜂以及苹小吉丁肿腿蜂），按5种蜂虫比例（0.5∶1，1∶1，2∶1，4∶1，8∶1），进行新疆野苹果林苹小吉丁套袋防治试验。结果表明：4种肿腿蜂均能成功寄生，而白蜡吉丁肿腿蜂以8∶1比例放蜂后30天，虫口校正减退率为65.56%，优于其他处理。将该肿腿蜂再次按5种放蜂比例直接释放在林间，在放蜂后30，45，60天分次调查防治效果，结果表明：以8∶1放蜂比例的处理，在第60天校正虫口减退率为50.97%，效果最佳。白蜡吉丁肿腿蜂适合在新疆防治苹小吉丁，且效果良好。

To explore the biological control measure of Agrilus mali Matsumura,four species of bethylid wasp in the genus Sclerodermus ( S. pupariae,S. guani and another two species) were used to test their control capacity to pest by bagging with 5 release ratio (parasitoid∶host:0. 5∶1,1∶1,2∶1,4∶1,8∶1). Results showed that,all four wasps were able to successfully parasitize on A. mali,especialy for S. pupariae,which caused 65. 56% reducing rate with release ratio 8∶1 in 30 d. Then S. pupariae was tested by directly releasing on the damaged apple trees with the 5 release ratios. After 30,45 and 60 d,the control effects were checked respectively. The result showed that,the treatment with 8∶1 release ratio,after 60 d performed the best,with 50. 97% corrected mortality. This research provided a successful case by using bethylid wasps to control A. mali,and offered a reference for appropriate release ratio of S. pupariae in the field.

对我国用于防治林木蛀干害虫的重要天敌昆虫类群——肿腿蜂科硬皮肿腿蜂属Sclerodermus Latreille1809的种类进行了订正性研究。研究表明,目前我国硬皮肿腿蜂属共有4个种,分别是管氏肿腿蜂Sclerodermus guani Xiao et Wu 1983,川硬皮肿腿蜂S.sichuanensis Xiao 1995,海南硬皮肿腿蜂S.hainanica Xiao 1995和白蜡吉丁肿腿蜂S.pupariae Yang et Yao 2012,另有1疑似分布种——哈氏肿腿蜂S.harmandi Buysson 1903。编制了区分这5个种的检索表。研究认为,日本和韩国专家将我国的管氏肿腿蜂更名为哈氏肿腿蜂(作为同物异名)是不合适的,管氏肿腿蜂应为一个有效种。对管氏肿腿蜂根据模式标本进行了再描述,提供了形态特征照片图;也引述了日本学者Terayama(2006)对哈氏肿腿蜂的再描述,以便区分这两个种。并以对照表的形式,给出了区分这两种的主要形态特征。同时也对作者2012年发表在美国的Annals of the Entomological Societuy of America上的新种——白蜡吉丁肿腿蜂做了简要描述,附有该种的形态特征照片图,并记述了该种的生物学、行为学特性,以便国内学者鉴定该种时参考。研究发现白蜡吉丁肿腿蜂也寄生栗山天牛Massicus raddei、光肩星天牛Anoplophora glabripennis、锈色粒肩天牛Apriona swansoni、咖啡脊虎天牛Xylotrechus grayii和白蜡窄吉丁Agrilus planipennis及苹小吉丁A.mali等我国多种重要的林木蛀干害虫,是一种可利用于防治这些害虫的优秀天敌。

The present paper reports the result of a revisional study of species of the genus Sclerodermus Latreille 1809 (Hymenoptera: Bethylidae) in China. Some Chinese species in the genus are important natural enemies parasitizing wood borers and have been used broadly to control the pests. There are four valid species in China fauna right now:Sclerodermus guani Xiao et Wu 1983, S. sichuanensis Xiao 1995, S. hainanica Xiao 1995, S. pupariae Yang et Yao 2012. A key to distinguish them is provided, including S. harmandi (Buysson 1903) which is suspected to distribute in China. It is considered that S. guani Xiao et Wu 1983 is a valid species rather than S. harmandi (Buysson 1903). For distinguishing the two species, S. guani is re-described in details, including apterous and alate females, as well as alate male with colorous photos, based on its holotype and paratypes conserved in the Insect Collection of Chinese Academy of Forestry. Meanwhile, the re-description of S. harmandi made by Terayama
