a Courtship index of males fed on YS food or S food. Mean ± SEM. *p < 0.05, two-tailed unpaired t-tests. b Males’ mating competitiveness when fed on YS food or S food. The top left panel represents a schematic diagram of the male mating competition assay. *p < 0.05, two-tailed Binomial test. c Left panel: The apical tip of a testis, where the FasIII-postive hub (asterix) is surrounded by Vasa-positive GSCs (dotted circle), the scale bar represented 10 μm. Right panel: Number of male GSCs when they were fed YS food or S food. Mean ± SEM. *p < 0.05, two-tailed Mann-Whitney nonparametric tests. d Male sperm competitiveness when fed on YS food or S food. Left panel: schematic diagram of male sperm competition assay. Right panel: number of GFP sperm remaining in the female seminal receptacle. Mean ± SEM. **p < 0.01, two-tailed unpaired t tests. Male resistance when fed YS food or S food. Survival rates of males under desiccation (e) and starvation (f) conditions. ***p < 0.001, Log-rank test. Female resistance when fed YS food or S food. Survival rates of males under desiccation (g) and starvation (h) conditions. ***p < 0.001, Log-rank test. Source data are provided as a Source Data file.
