Mating and receiving ejaculate can alter female insect physiology and postcopulatory behaviour. During mating, females receive both internal and external stimuli and different components in the ejaculate. In insects, these components consist mostly of sperm and male accessory gland secretions. Some of the most important changes associated with receiving male accessory gland secretions are a reduction in female sexual receptivity and an increase in oviposition. However, a clear function for these molecules has not been found in the Mexican fruit fly Anastrepha ludens (Loew) (Diptera: Tephritidae). Here, we tested how the stimulus of mating, receiving a full ejaculate, or only receiving accessory gland secretions can influence ovarian development and oviposition. Our results indicate that the stimulus of mating per se is enough to induce oviposition and increase egg laying in females even if ejaculate is not received, whereas receiving only accessory gland secretions does not increase ovarian development and is not enough to induce oviposition or increase egg production. Further research on the internal and external copulatory courtship of A. ludens will increase our understanding of the role of these secretions in stimulating oviposition independent of ejaculate effects. A biological function for male accessory gland secretions on female behaviour for A. ludens still needs to be found.

交配和接受射精可以改变雌性昆虫的生理机能和交配后的行为。在交配过程中，雌性会接受内部和外部刺激以及射精中的不同成分。在昆虫中，这些成分主要由精子和雄性附属腺分泌物组成。与接受男性附属腺分泌物相关的一些最重要的变化是女性性接受能力的降低和产卵量的增加。然而，在墨西哥实蝇Anastrepha ludens (Loew) (Diptera: Tephritidae) 中尚未发现这些分子的明确功能。在这里，我们测试了交配、接受完整射精或仅接受附属腺体分泌物的刺激如何影响卵巢发育和排卵。我们的结果表明交配的刺激即使不接受射精，本身就足以诱导雌性产卵和增加产卵，而仅接受辅助腺分泌物并不能促进卵巢发育，也不足以诱导产卵或增加产卵量。对A. ludens内部和外部交配求爱的进一步研究将增加我们对这些分泌物在刺激排卵中的作用的理解，而不受射精影响。雄性附属腺分泌物对A. ludens雌性行为的生物学功能仍有待发现。
