“…It is unclear if the large size of males also influences fitness in the field, although laboratory studies support the idea that larger males are fitter. 22,70,71 We found no difference in measurements between gravid and parous versus nulliparous females. Field studies on blood feeding success suggests a negative association with size 25,72 or no strong evidence of association.…”

“…Because there is no strong evidence that smaller females have higher survival in smaller females, 25,67 we suspect that the third reason is not likely to be important. We also suspect that there is unlikely to be an insemination bias given the results of laboratory studies 22 ; the results may therefore reflect success in blood feeding or egg retention, but sorting this out requires further work.…”

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.

“…Larval fitness traits: Initial experiments were carried out to determine a larval nutritional stress level that resulted in changes in larval development time and adult body size, correlates of mosquito fitness (Bedhomme et al 2003;Ponlawat and Harrington 2009). A significant increase in larval development time, compared to control levels (1.0 mg food/larva/day), was first observed for larvae provided with 0.25 mg food/larva/day (P , 0.01, t -test).…”

“…Larger males are known to inseminate females with more sperm, which may improve their chances of fertilization, while larger females may have a higher chance of being inseminated (Ponlawat and Harrington 2009). However, the spread of Wolbachia may be compromised under high density conditions due to a relatively lower rate of insemination of infected females.…”

Forty percent of the world's population is at risk of contracting dengue virus, which produces dengue fever with a potentially fatal hemorrhagic form. The wMelPop Wolbachia infection of Drosophila melanogaster reduces life span and interferes with viral transmission when introduced into the mosquito Aedes aegypti, the primary vector of dengue virus. Wolbachia has been proposed as an agent for preventing transmission of dengue virus. Population invasion by Wolbachia depends on levels of cytoplasmic incompatibility, fitness effects, and maternal transmission. Here we characterized these traits in an outbred genetic background of a potential target population of Ae. aegypti using two crossing schemes. Cytoplasmic incompatibility was strong in this background, and the maternal transmission rate of Wolbachia was high. The infection substantially reduced longevity of infected adult females, regardless of whether adults came from larvae cultured under high or low levels of nutrition or density. The infection reduced the viability of diapausing and nondiapausing eggs. Viability was particularly low when eggs were laid by older females and when diapausing eggs had been stored for a few weeks. The infection affected mosquito larval development time and adult body size under different larval nutrition levels and densities. The results were used to assess the potential for wMelPop-CLA to invade natural populations of Ae. aegypti and to develop recommendations for the maintenance of fitness in infected mosquitoes that need to compete against field insects.

“…Body size is an important indicator of female reproductive success; larger size is associated with greater fecundity, 41,46 blood feeding success 47 and mating success. 48 The wMelPop infection significantly reduced body size (wing length) in slow developers relative to uninfected Ae. aegypti adults.…”

Abstract. The intracellular endosymbiont Wolbachia has been artificially transinfected into the dengue vector Aedes aegypti, where it is being investigated as a potential dengue biological control agent. Invasion of Wolbachia in natural populations depends upon the fitness of Wolbachia-infected Ae. aegypti relative to uninfected competitors. Although Wolbachia infections impose fitness costs on the adult host, effects at the immature stages are less clear, particularly in competitive situations. We look for effects of two Wolbachia infections, wMel and wMelPop, on intra-strain and interstrain larval competition in Ae. aegypti. Development of Wolbachia-infected larvae is delayed in mixed cohorts with uninfected larvae under crowded-rearing conditions. Slow developing wMelPop-infected larvae have reduced adult size compared with uninfected larvae, and larvae with the wMel infection are somewhat larger and have greater viability relative to uninfected larvae when in mixed cohorts. Implications for successful invasion by these Wolbachia infections under field conditions are considered.
