Per Se

The rate of egg deposition by mature virgin females of the migratory grasshopper, Melanoplus sanguinipes (F.), increased markedly after implantation of accessory glands from mature males. Implants consisting of one-half of a complete set of glands, or of the 10 short hyaline glands alone, were about equally effective in increasing the rate of egg deposition. However, in each case the oviposition rate was less than that of normally mated females of the same age. Implanting only the white glands of the accessory gland complex had a lesser effect on egg-laying and implants of the long hyaline gland or of the seminal vesicle had little or no effect.Our results indicate that the physical act of mating per se or the presence of sperm probably do not provide the primary stimulus to egg-laying. The abdominal location of the implanted accessory gland does, however, suggest that some diffusible chemical substance is responsible for increasing egg deposition in these virgin females.

External Stimuli

Abstract 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.
