“…In addition, there is evidence of intersexual selection including female- and male-mate choice ( Friberg and Arnqvist 2003 ; LeVasseur-Viens et al 2015 ). In the latter case, if males favor larger females, a choice that may correlate with female fecundity in species where body size correlates positively with ovariole number ( Bonduriansky 2001 ; Byrne and Rice 2006 ; Sinclair et al 2021 ), then this could result in positive selection on amino acid changes favoring increased ovariole numbers. Moreover, Drosophila exhibits sexual antagonism, which could also potentially shape female (and male) reproductive characteristics and their underlying genes ( Arnqvist and Rock 1995 ; Rice 1996 ; Swanson et al 2004 ; Innocenti and Morrow 2010 ).…”

Ovaries play key roles in fitness and evolution: they are essential female reproductive structures that develop and house the eggs in sexually reproducing animals. In Drosophila, the mature ovary contains multiple tubular egg-producing structures known as ovarioles. Ovarioles arise from somatic cellular structures in the larval ovary called terminal filaments, formed by terminal filament cells and subsequently enclosed by sheath cells. As in many other insects, ovariole number per female varies extensively in Drosophila. At present however, there is a striking gap of information on genetic mechanisms and evolutionary forces that shape the well-documented rapid interspecies divergence of ovariole numbers. To address this gap, here we studied genes associated with D. melanogaster ovariole number or functions based on recent experimental and transcriptional datasets from larval ovaries, including terminal filaments and sheath cells, and assessed their rates and patterns of molecular evolution in five closely related species of the melanogaster subgroup that exhibit species-specific differences in ovariole numbers. From comprehensive analyses of protein sequence evolution (dN/dS), branch-site positive selection, expression specificity (tau) and phylogenetic regressions (PGLS), we report evidence of 42 genes that showed signs of playing roles in the genetic basis of interspecies evolutionary change of Drosophila ovariole number. These included the signalling genes upd2 and Ilp5 and extracellular matrix genes vkg and Col4a1, whose dN/dS predicted ovariole numbers among species. Together, we propose a model whereby a set of ovariole-involved gene proteins have an enhanced evolvability, including adaptive evolution, facilitating rapid shifts in ovariole number among Drosophila species.

“…We also found no size difference between mated and unmated female flies. Although male mating size bias for larger females is evident across many insect species (Bonduriansky 2001; Sinclair, Lisa, & Pischedda 2021), this possibility remains rarely researched in comparison with the well demonstrated female choice of males found in other fly groups such as lek forming fruit fly species (Shelly 2018). Perching sites have been found to significantly increase mating in medfly mass rearing systems that are known to perch, like male E. tenax , in the field (Fitzpatrick 1979; Liedo et al 2007).…”

Developing mass rearing systems for the drone fly, Eristalis tenax, is a crucial step toward its use as a complementary commercial pollinator. To meet the timing of commercial needs for E. tenax, there is significant value to both predicting and managing reproductive output and development within the rearing protocol. To help achieve this, our study focuses on the laboratory manipulation of adult mating and the timing of the development of eggs in E. tenax. To stagger colony cohorts, egg rearing temperatures ranging from 12 to 30°C were found to be suitable for both successful egg development and hatching viability (97 to 28.3 h to first hatch, respectively). The mating window for E. tenax females was established to commence from 2 weeks post eclosion and reached 75 ± 11% mated at 7 weeks. Reproductive output over 12 weeks was assessed in separate cage manipulation trials: (1) varying the sex ratio with 20:40, 30:30 and 40:20 female and male flies respectively per cage and (2) varying the adult density per cage with 15:15, 30:30, 60:60 and 120:120 female and male flies per cage. Female percentage mated and egg cluster size, which averaged 200.6 ± 4.3 eggs per cluster, did not change between treatments in the sex ratio and density trials. Egg cluster output per female was significantly reduced for treatments across both trials, which had more than 30 females in a cage. A stocking rate of 15:15 produced 86% more eggs per female than expected, a percentage well above that of all other treatments. However, the highest stocking density produced the most eggs when assessed at a per cage level. Fly survival was significantly different between the sexes across both trials with males dying earlier in cages stocked with more females than males. Although the fly colonies were held at constant temperatures and light conditions for 6 months, we found evidence of endogenous overwintering behaviours among flies resulting in lower mating rates, egg hatching success and greater longevity among flies studied over winter.

Ovaries play key roles in fitness and evolution: they are essential female reproductive structures that develop and house the eggs in sexually reproducing animals. InDrosophila, the mature ovary contains multiple tubular egg-producing structures known as ovarioles. Ovarioles arise from somatic cellular structures in the larval ovary called terminal filaments, formed by terminal filament cells and subsequently enclosed by sheath cells. As in many other insects, ovariole number per female varies extensively inDrosophila. At present however, there is a striking gap of information on genetic mechanisms and evolutionary forces that shape the well-documented rapid interspecies divergence of ovariole numbers. To address this gap, here we studied genes associated withD. melanogasterovariole number or functions based on recent experimental and transcriptional datasets from larval ovaries, including terminal filaments and sheath cells, and rigorously assessed their rates and patterns of molecular evolution in five closely related species of themelanogastersubgroup that exhibit species-specific differences in ovariole numbers and have annotated genomes. From comprehensive analyses of protein sequence evolution (dN/dS), branch-site positive selection, expression specificity (tau) and phylogenetic regressions (PGLS), we report evidence of 42 genes that showed signs of playing roles in the genetic basis of interspecies evolutionary change ofDrosophilaovariole number.
