Sexual cannibalism is a phenomenon that has been reported in a wide variety of invertebrate predators. In arthropods, it has been documented mostly in arachnids. The Dryinidae, a small cosmopolitan family of aculeate hymenopterans, are exclusively parasitic of the hemipteran suborders Cicadomorpha and Fulgoromorpha. They include some species that have been successfully employed in biological control programs. The ecology and biology of the Dryinidae is generally little known. In this short communication, studying biological traits of Gonatopus chilensis, a parasitoid of planthoppers, we report two novel facts for dryinid species: occasionally virgin females were re-mated by the same male, and after mating, occasionally young females caught the male and devoured its gaster. This is the first record of sexual cannibalism for the family Dryinidae and, to our knowledge, for the order Hymenoptera.

膜翅目动物类dry虫的交配行为和性相食的首次记录

性食人是一种无脊椎动物捕食者的一种现象。在节肢动物中，大部分已记录在蜘蛛纲动物中。Dryinidae是一种小型的世界性的不规则膜翅目昆虫，仅寄生于半翅目亚纲蝉蝉和短尾蝉。它们包括一些已成功用于生物防治计划的物种。in科的生态和生物学通常鲜为人知。在这段简短的交流中，研究了吉纳托普斯小鸡的生物学特性是飞虱的寄生虫，我们报道了有关dry类物种的两个新事实：偶尔由同一只雄性重新交配初生雌性，交配后，偶尔有年轻雌性抓住雄性并吞噬其胃气。这是Dryinidae家族和膜翅目（Hymenoptera）的第一个食人性记录。
