“…37 Larger adult body sizes has been linked to higher egg production in females and higher spermatophore production in males. [38][39][40] Using the regression equation Y = 2.505 X -8.616, where X = cube wing length (mm) relating cubic wing length to egg production, 40 we can predict how many eggs a female will lay for one gonotrophic cycle in both density treatments. Based on average wing length for each treatment, females from the low-density treatment were predicted to produce 36 eggs/cycle compared with a predicted 27 eggs/cycle in the high-density treatment.…”

Abstract. Transgenic strains of Aedes aegypti have been engineered to help control transmission of dengue virus. Although resources have been invested in developing the strains, we lack data on the ecology of mosquitoes that could impact the success of this approach. Although studies of intra-specific competition have been conducted using Ae. aegypti larvae, none of these studies examine mixed age cohorts at densities that occur in the field, with natural nutrient levels. Experiments were conducted in Mexico to determine the impact of direct and delayed density dependence on Ae. aegypti populations. Natural water, food, and larval densities were used to estimate the impacts of density dependence on larval survival, development, and adult body size. Direct and delayed density-dependent factors had a significant impact on larval survival, larval development, and adult body size. These results indicate that control methods attempting to reduce mosquito populations may be counteracted by density-dependent population regulation.

“…This result may reflect the fact that large females have an increased fecundity. [63][64][65][66] Larger females may also have a better flight range, higher survival, increased host finding, and blood feeding success, and improved ability to locate oviposition sites. 67,68 Larger also means higher energy reserves, 67 and by having a higher mass/surface area ratio, they might be less prone to desiccation than small mosquitoes.…”

Abstract. There is increasing interest in rearing modified mosquitoes for mass release to control vector-borne diseases, particularly Wolbachia-infected Aedes aegypti for suppression of dengue. Successful introductions require release of high quality mosquitoes into natural populations. Potential indicators of quality are body size and shape. We tested to determine if size, wing/thorax ratio, and wing shape are associated with field fitness of Wolbachia-infected Ae. aegypti. Compared with field-collected mosquitoes, released mosquitoes were larger in size, with lower size variance and different wing shape but similar in wing-thorax ratio and its associated variance. These differences were largely attributed to nutrition and to a minor extent to wMel Wolbachia infection. Survival potential of released female mosquitoes was similar to those from the field. Females at oviposition sites tended to be larger than those randomly collected from BG-Sentinel traps. Rearing conditions should thus aim for large size without affecting wing/thorax ratios.

“…Protandry, here defined as the arrival of males before females into a seasonal breeding population, is common among insects and is predicted to occur most often where females are monogamous (e.g., butterflies and mosquitoes) whereby sexual selection theory predicts males maximize mating opportunities (Wiklund and Fagerstro¨m 1977;Nylin et al 1993;Kleckner et al 1995;ZijIstra et al 2002). Natural selection may act differently on male and female mosquitoes, since female fitness is related to fecundity whereas male fitness depends on the number of matings (Steinwascher 1982;Kleckner et al 1995). Therefore, sex-specific reaction norms, induced by biological interactions (e.g., larval competition and predation) would be expected for aedine mosquitoes.…”

Habitat complexity and sex-dependent predation of mosquito larvae in containers

Studies in aquatic systems have shown that habitat complexity may provide refuge or reduce the number of encounters prey have with actively searching predators. For ambush predators, habitat complexity may enhance or have no effect on predation rates because it conceals predators, reduces prey detection by predators, or visually impairs both predators and prey. We investigated the effects of habitat complexity and predation by the ambush predators Toxorhynchites rutilus and Corethrella appendiculata on their mosquito prey Aedes albopictus and Ochlerotatus triseriatus in container analogs of treeholes. As in other ambush predator-prey systems, habitat complexity did not alter the effects of T. rutilus or C. appendiculata whose presence decreased prey survivorship, shortened development time, and increased adult size compared to treatments where predators were absent. Faster growth and larger size were due to predator-mediated release from competition among surviving prey. Male and female prey survivorship were similar in the absence of predators, however when predators were present, survivorship of both prey species was skewed in favor of males. We conclude that habitat complexity is relatively unimportant in shaping predator-prey interactions in this treehole community, where predation risk differs between prey sexes.
