“…It is therefore likely that LMs had larger testes and thus greater sperm produ ction potential than SMs. In support of this suggestion, it has been reported that in some dipterans the sizes of the ovary (Botto-Mahan & Medel, 2007) and testis (Pitnick, 1996) increase with body size. In mating experiments, we found that egg production varied considerably with body size of adults forming cross-mating pairs.…”

Body size is a physical factor of crucial importance underlying important traits of the reproductive dynamics of both sexes in mosquitoes. Most studies on the influence of body size in mating success of dengue vectors addressed sperm transfer to females and did not consider egg production, a prerequisite for population maintenance; male body size impact on reproduction has attracted little research interest with respect to sterile insect technique. In experiments involving differently sized adults, we examined whether the body size of the mates is a source of variation in reproductive outcome in Aedes aegypti. In the absence of male partners, large females (LF) showed better fecundity than small females (SF). In intraclass mating trials, egg production was much greater in largesized than smallsized pairs. There were comparable fecundities in large females mated with small males and large pairs. [SF•SM] and [SF•LM] pairs showed equivalent fecundity. Nonmating did not result in the production of viable eggs by either small or large females. We also observed that eggs produced by largesized females mated with small males had better hatching success than those from either small or large pairs. Mating between small females and large males resulted in poor egg viability.

“…In drosophilids, testis size has been shown to increase with body size (Pitnick, 1996). In addition, ovary mass is heavier in larger than smaller females fruit flies (Botto-Mahan & Medel, 2007). Gonad size is positively correlated with sperm production and transfer rates (Baker et al, 2003).…”

“…To measure the dispersal capacity in each locality, the proportion of winged individuals (WP) was estimated in each site by counting the total number of fifth‐instar nymphs with wing pads (winged as adult) divided by the total number of fifth‐instar nymphs in the site. As a proxy of insect survival and reproductive potential, the female abdomen area (AA) was calculated (Botto‐Mahan & Medel, 2007; Maciel‐de‐Freitas et al, 2007). To this end, all captured females were photographed on graph paper to measure maximum abdomen width (AW) and length (AL) using imagej software (version 1.8.0; Schneider et al, 2012).…”

Genetic diversity in a restricted‐dispersal kissing bug: The centre–periphery hypothesis halfway

et al. 2021

Ecological, climatic and evolutionary processes play important roles determining genetic diversity on a wide geographical scale (Jin et al., 2020). The centre-periphery hypothesis (CPH) proposes that populations near the distribution limit of a species present lower genetic diversity and higher differentiation than populations located in the centre (Eckert et al., 2008). This pattern could be explained because the centre of a species distribution will probably correspond to its optimal habitat, presenting environmental conditions associated with higher absolute fitness, which may be
