【摘要】 对松毛虫黑卵蜂的产卵行为及寄主选择进行观察试验,结果表明,黑卵蜂产卵过程分为3个阶段9个步骤;当其在马尾松毛虫卵上寄生时,与寄主卵卵块和卵粒的大小及颜色无关。将马尾松毛虫卵与人工卵放在一起时,黑卵蜂只选择松毛虫卵。但在人工卵上涂上马尼松毛虫体表鳞片时,可引诱黑卵蜂在其上完成整个产卵过程。更多还原

【Abstract】 The oviposition behavior and host selection of Telenomus dendrolimus have been studied. The results indicate that the oviposition process can be divided into 3 stages and 9 steps, and that the host selection bears no relation to the size and color of the eggs or egg masses. It only parasitizes on the eggs of Dendrolimus punctatus, and the parasitical ratio on artificial eggs is zero. But the artificial eggs, when painted with the scales of the host, can attract the parasitoid to complete the oviposition process.更多还原
