“…The importance of larval nutrition in the expression of autogeny has been reported in other mosquito species. 19,31,37 Following blood feeding, amino acid titers increase in the hemolymph triggering a cascade of metabolic events that culminates with eggs production. 38 It is likely that autogenous individuals are able to mobilize enough amino acids stored in the fat body during larval stages to trigger vitellogenesis.…”

Abstract. Some mosquito strains or species are able to lay eggs without taking a blood meal, a trait named autogeny. This may allow populations to persist through times or places where vertebrate hosts are scarce. Autogenous egg production is highly dependent on the environment in some species, but the ideal conditions for its expression in Aedes aegypti mosquitoes are unknown. We found that 3.2% of females in a population of Ae. aegypti from Kenya were autogenous. Autogeny was strongly influenced by temperature, with many more eggs laid at 28 C compared with 22 C. Good nutrition in larval stages and feeding on higher concentrations of sugar solution during the adult stage both result in more autogenous eggs being produced. The trait also has a genetic basis, as not all Ae. aegypti genotypes can lay autogenously. We conclude that Ae. aegypti requires a favorable environment and a suitable genotype to be able to lay eggs without a blood meal.

“…Following eclosion, the water in the glass vials was removed and the glass vials along with the adult mosquitoes were stored at -20°C for 2 hours to kill the insects. Then the vials were placed in a hot air oven with a temperature of 40°C maintained for 48 hours to dry the samples, following the protocol used elsewhere (TELANG et al 2006(TELANG et al , 2007. This process was adopted for adults emerging within a 2 hour time frame; the remainder were continuously monitored for eclosion to adult stage.…”

ABSTRACT. Energy reserves in mosquitoes are an indicator of fitness, linking larval effort in resource acquisition with adult survival and fecundity. In other words, life history strategies and disease transmission potential can be related to the amount of energy reserves. The energy reserves of four mosquitoes -Aedes aegypti, Aedes albopictus, Armigeres subalbatus and Culex quinquefasciatus (Diptera: Culicidae) -were calculated to justify species-specific differences in their life history strategies. Following repeated sampling of pupae from the respective larval habitats, the glycogen, sugar and lipid contents of individual mosquitoes were assessed and corroborated with pupal weight and adult wing length. Discriminant function analysis was used to acquire an initial reflection of the differences of the parameters among the sex and species of the mosquitoes considered in the study. Using logistic regression and ANOVA, the effects of species and sex as contributors to variations in energy reserves could be established. The results indicated that for all the mosquitoes, sex-specific differences were prominent with reference to the energy reserves. Species-specific differences in energy reserves reflect differences in resource acquisition and assimilation in the tissues, and thus the differences in the life history strategies of these four species.

Effects of larval nutrition on the endocrinology of mosquito egg development

Abstract: JH, in comparison with similarly staged Oc. atropalpus. Ecdysteroid production was initiated in newly emerged Oc. atropalpus females, which have higher protein reserves and which develop eggs without a blood meal, which is required by A. aegypti females to complete egg development.
