“…The decline in offspring fecundity with increasing maternal age found in this and previous rotifer studies 23,76 differs from some reports for C. elegans , Daphnia , and Drosophila , in which offspring from the youngest or smallest mothers have been shown to have lower lifetime reproduction than those from older mothers 34,40,83 . One possible explanation is that differences in reproductive strategy may drive the differences in offspring outcomes with changing maternal age among varied small, short-lived invertebrate species.…”

“…A decrease in offspring lifespan with increasing maternal age was first demonstrated in rotifers–microscopic, aquatic invertebrate animals–and has come to be known as the “Lansing Effect” 23,24,33 . Declines in offspring health, lifespan, and stress resistance with increasing maternal age have since been demonstrated across taxa, ranging from invertebrates like soil mites and Drosophila , to mammals including mice and humans 26,27,29–32,34–36 . The mechanisms of these maternal age effects are unclear, and have variously been attributed to increases or decreases in maternal investment in reproduction with increasing maternal age, as well as to other, as yet undefined, epigenetic factors 37–44 .…”

Maternal age has a negative effect on offspring lifespan in a range of taxa and is hypothesized to influence the evolution of aging. However, the mechanisms of maternal age effects are unknown, and it remains unclear if maternal age alters offspring response to therapeutic interventions to aging. Here, we evaluate maternal age effects on offspring lifespan, reproduction, and the response to caloric restriction, and investigate maternal investment as a source of maternal age effects using the rotifer, Brachionus manjavacas , an aquatic invertebrate. We found that offspring lifespan and fecundity decline with increasing maternal age. Caloric restriction increases lifespan in all offspring, but the magnitude of lifespan extension is greater in the offspring from older mothers. The trade-off between reproduction and lifespan extension under low food conditions expected by life history theory is observed in young-mother offspring, but not in old-mother offspring. Age-related changes in maternal resource allocation to reproduction do not drive changes in offspring fitness or plasticity under caloric restriction in B. manjavacas . Our results suggest that the declines in reproduction in old-mother offspring negate the evolutionary fitness benefits of lifespan extension under caloric restriction.

“…Lines with postponed senescence have early ovary weights one-third to one-half of those of the control lines. The apparent consistency, over generations, of ovary weight differentiation at an early age contrasts with the results of Lints and Hoste (1977). They observed erratic variation in life history characters from generation to generation when lines were maintained by reproduction at early and late ages.…”

SERVICE. 1984. The morphology of postponed senescence in Drosophila melanogaster. Can. J . Zool. 62: 1576-1580. Five laboratory populations of Drosophila melanogaster which exhibit postponed senescence were compared with five control populations. Comparisons were made with respect to weights of whole bodies, body parts, and water content. Ovaries of young adults from populations exhibiting postponed senescence were approximately half the weight of ovaries of flies from control populations. This result was obtained in two experiments. Whole wet body weight was significantly greater for control populations in one experiment, but not in a second. Males from control populations had significantly less proportional water content than males from populations exhibiting postponed senescence. The reduction in young adult ovary weight in flies from populations with postponed senescence supports the concept of a trade-off between reproductive effort and longevity. ROSE, M. R., M. L.

“…Different techniques such as individual holding cup [ 14 ], small cage [ 17 ], plastic cups [ 24 ], or tubes/ Drosophila vials [ 23 , 25 , 26 , 27 ] are feasible for individual oviposition assays in mosquitoes. The last one was originally developed for Drosophila experiments [ 28 , 29 , 30 , 31 ], and adapted for mosquito oviposition assays (especially in Aedes genus). This method uses wet cotton covered with filter paper or only water-soaked funnel filter paper as a wet surface to allow Aedes females to lay eggs.…”

Aedes aegypti is the principal vector of the urban arboviruses and the blood ingestion is important to produce the eggs in this species. To analyze the egg production in Ae. aegypti, researchers frequently use small cages or Drosophila vials to collect eggs from gravid females. Although it is affordable, the setup is time- and space-consuming, mainly when many mosquitoes need to be individually analyzed. This study presents an easy, cheap, and space-saving method to perform individual oviposition assays in Ae. aegypti using cell culture plates. This new method to access fecundity rate was named “oviplate”. The oviplates are setup with 12- or 24-well plates, distilled water and filter paper and they are 78 to 88% cheaper than the traditional Drosophila vial assay, respectively. Furthermore, to allocate 72 vitellogenic females in an insectary using Drosophila vial is necessary 4100 cm3 against 1400 cm3 and 700 cm3 when using 12- and 24-well plates, respectively. No statistical differences were found between the number of eggs laid in Drosophila vials and the oviplates, validating the method. The oviplate method is an affordable, and time- and space-efficient device, and it is simpler to perform individual fecundity analyses in Ae. aegypti.
