“…We showed here that starvation induces the early onset of rapid egg resorption (see Figure 6), as has been shown in other parasitoid species as well (Bell & Bohm, 1975). In our study, all but one mature oocyte was resorbed within 36 h of females being deprived of honey.…”

The diet of adult females of the parasitoid Aphytis melinus DeBach (Hymenoptera: Aphelinidae) includes host insects and sugar-rich foods such as nectar and honeydew. We compared the contributions of host feeding to longevity and fecundity in A. melinus females in the presence and in the absence of honey meals. First, we assessed the longevity of females that were not allowed to oviposit. While the longevity of females fed honey was significantly increased by host feeding (median ages were 30.5 days for host-fed females and 17 days for females not allowed to host feed), the lifespan of parasitoids not fed honey did not exceed 3 days for any individual and there was no effect of host feeding on longevity in this group. In the second set of experiments, we assessed the fecundity and longevity of females allowed to oviposit. We conducted two experiments, one in which honey was continuously available, and one in which honey was not available. In both experiments, daily observations were made of females that were either allowed to host feed or manually prevented from host feeding. In the presence of honey, host feeding significantly increased both fecundity and longevity, and in the absence of honey, parasitoids died within 2 days and host feeding had no significant effect on either fecundity or longevity. The lifetime fecundity of females fed honey but not hosts exceeded the initial egg complement by 60% on average. Approximately one host per day was used for host feeding whether honey was supplied or not, and each host-feeding meal contributed approximately 3.9 eggs to the lifetime fecundity of honey-fed females. In the last experiment, we compared the rate of egg resorption over a 36-h period in A. melinus females that were deprived of hosts and either fed honey or starved. While no egg resorption was detected in honey-fed females over this time period, starved females resorbed approximately 9 eggs. Thus, the availability of a sugar-rich food interacts strongly with host feeding in influencing longevity and fecundity and has a strong direct effect on egg resorption.

“…Unsuitable physiological, behavioral, or environmental factors such as starvation, mating delay, host deprivation, and lack of available oviposition sites may cause the degeneration of some follicles. In other words, some oocytes undergo oosorption, the resorption of oocytes in the ovary (Bell and Bohm, 1975;Aguirre et al, 2011;Guo et al, 2011). This process is known as follicular atresia and these type follicles are termed atretic follicles.…”

Oocyte development in the ovary of the black cricket, Melanogryllus desertus, was investigated. In the panoistic ovary of M. desertus, oocyte developmental stages based on their histological properties were classified as previtellogenic, vitellogenic, and maturation. Oocytes were encircled by follicle cells through the developmental stages. In the previtellogenic stage, a few vacuoles were observed just beneath the oolemma. At the beginning of the vitellogenic stage, subdivided into early-, middle-, and late-vitellogenic stages, yolk granules within the oocyte were initially observed just beneath the oolemma. In addition, small lipid droplets were initially present under the yolk granules. As vitellogenesis proceeded, both yolk granules and lipid droplets gradually increased and moved inside the oocyte. The Balbiani body was detected around the nucleus. In the maturation stage, large yolk granules covering the whole of the oocytes were determined. Some atretic oocytes occurring as a result of resorption of oocytes (oosorption) by hypertrophied follicle cells were also detected. Apoptosis in atretic follicles was observed as well.

“…Mothers may be able to absorb female eggs under poor prey conditions, known as oosorption (resorption of oocytes), which is an effective mechanism to save resources on eggs in various insect species (Bell & Bohm, 1975). This is based on the idea that the sex of oocytes is already determined in the ovary upon emergence.…”
