摘要: 带纹长距姬小蜂Euplectrus cinctiventris Ferrière是国槐尺蠖的一种重要的寄生性天敌,了解其生物学习性对于发挥其生态功能及在害虫防治中都有重要意义。本研究采取显微拍照、人工饲养的方法,对带纹长距姬小蜂的形态特征、生活史、寄主选择等生物学特性进行了系统研究。结果表明,带纹长距姬小蜂具有典型的外寄生性生活史,在26℃饲喂30%蜂蜜水的条件下,寄生蜂雌蜂寿命可达33.5 d。主要寄生2~4龄的国槐尺蠖幼虫,产卵于寄主1~4腹节背面,可根据寄主的大小调节产卵量和雌雄比例。在寄主2~4龄期幼虫雌雄比例分别为2.1:1.5,4.6:2.5,8.9:1.8。寄主的龄期越大,寄生蜂繁育仔代蜂的数量越多,后代雌蜂比例越高。卵、幼虫、蛹的发育起点温度为9.96℃、12.45℃、18.26℃,有效积温分别为16.04、83.74和55.73日·度。本研究为带纹长距姬小蜂的生物防治提供了理论基础和实践指导。

Abstract: Euplectrus cinctiventris Ferrière is an important parasitic natural enemy of Semiothisa cmerearia. Investigation of the biological characteristics of E. cinctiventris is of a great significance for understanding its ecological function and application in pest control. This study systematically investigated the biological traits of E. cinctiventris, including morphological features, life history, and host selection, using microscopic photography and artificial rearing methods. The results showed that E. cinctiventris has a typical ectoparasitic life history. Under the condition of feeding 30% honey water at 26 ℃, the lifespan of the female wasps reached 33.5 days. The wasps mainly parasitized the 2nd—4th instar larvae of S. cmerearia, with eggs laid on the dorsal surface of the 1st—4th abdominal segments of the host. The fecundity and offspring sex ratio of the wasp varied according to the host size. The female-to-male sex ratios of offspring reared on the 2nd—4th instar host larvae were 2.1:1.5, 4.6:2.5, and 8.9:1.8, respectively. A positive correlation was observed between the instar of parasitized hosts and both the number of eggs laid by the wasps and the proportion of female offspring. The developmental threshold temperatures for the egg, larva, and pupa were 9.96, 12.45, and 18.26 ℃, respectively, with effective accumulated temperatures of 16.04, 83.74, and 55.73 day-degrees, respectively. This results provide a valuable theoretical support and practical guidance for utilizing E. cinctiventris in biological control.
