We reared a Telenomus species from eggs of Bombyx mandarina (Moore) (Lepidoptera: Bombycidae) and Bombyx mori (Linnaeus) (Lepidoptera: Bombycidae) in Japan, and from eggs of B. mandarina in Taiwan. Morphological examination revealed that this Telenomus species is new to science. In this article, we describe it as Telenomus moricolus Matsuo et Hirose, sp. nov. Because B. mandarina is considered to be an ancestor of B. mori, a domestic insect, it is reasonable to assume that B. mandarina is an original host of T. moricolus. This is the second discovery of an egg parasitoid attacking wild and domesticated silkworms, following the first discovery of T. theophilae, a Chinese species. The significance of the discovery of T. moricolus is discussed in relation to examining the effects of host-insect domestication on egg parasitism.
我们在日本从野桑蚕（Moore）（鳞翅目：蚕蛾科）和家蚕（Linnaeus）（鳞翅目：蚕蛾科）的卵中饲养出一种缘腹细蜂属物种，并在台湾从野桑蚕的卵中饲养出该物种。形态学检查表明，这种缘腹细蜂属物种是科学上新发现的。在本文中，我们将其描述为桑蚕缘腹细蜂Matsuo et Hirose，新种。由于野桑蚕被认为是家蚕这一驯化昆虫的祖先，因此有理由认为野桑蚕是桑蚕缘腹细蜂的原始寄主。这是继首次发现中国物种嗜蛾缘腹细蜂之后，第二次发现攻击野生和驯化家蚕的卵寄生蜂。本文结合研究寄主昆虫驯化对卵寄生的影响，讨论了桑蚕缘腹细蜂发现的意义。
