The potential of the parasitoid Psyllaephagus bliteus Riek for the biological control of the eucalyptus pest Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae) nymphs is high. This research sought to analyze the courtship, male competition, and mating behavior of P. bliteus at the proportions of 1:1 and 2:1 males to female in a Petri dish (5 cm diameter), and to describe the ovary histology of virgin and mated females of this parasitoid. At 1:1, males touch the antennae and thorax–abdomen of females during courtship, but females avoid mate attempts before they are 48 h old. At 2:1, the competition between male parasitoids inhibits mating. The histology of ovaries of virgin and mated P. bliteus females is similar, with two well-defined germarium and vitellarium regions, with oocytes at different developmental stages, including mature ones rich in yolk and with eggshell. A clearer understanding of the reproductive behavior and histology of P. bliteus aids in the use of this parasitoid for the biological control of G. brimblecombei.

若虫寄生蜂 Psyllaephagus bliteus（膜翅目：昆虫科）的求偶、交配行为和卵巢组织学

寄生蜂 Psyllaephagus bliteus Riek 对桉树害虫 Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae) 若虫的生物防治潜力很高。本研究旨在分析 P. bliteus 在培养皿（直径 5 厘米）中以 1:1 和 2:1 的雄性与雌性比例时的求偶、雄性竞争和交配行为，并描述处女的卵巢组织学和这种寄生蜂的雌性交配。在 1:1 时，雄性在求爱期间会接触雌性的触角和胸腹部，但雌性会在 48 小时之前避免交配尝试。在 2:1 时，雄性寄生蜂之间的竞争会抑制交配。处女和交配的 P. bliteus 雌性卵巢的组织学相似，具有两个明确的胚区和卵黄区，卵母细胞处于不同的发育阶段，包括成熟的富含蛋黄和蛋壳的。更清楚地了解 P. bliteus 的繁殖行为和组织学有助于使用这种寄生蜂对 G. brimblecombei 进行生物控制。
