Resource competition affects the developmental outcome of the acoustic parasitoid fly Ormia ochracea

The following are data files required to generate figures in Dominguez et al. (2025) published in Annals of the Entomological Society of America. In this study, we investigate the effects of resource competition on the developmental outcomes of the the acoustic parasitoid fly Ormia ochracea. Our results demonstrate that increasing fly larval competition with a host cricket reduces both pupation and eclosion success and produces significantly smaller fly pupae. Pupal width strongly predicts adult fly size, suggesting that the effects of larval competition carry forward into adulthood—even after direct competition has ended. These findings support the hypothesis that early nutritional constraints shape downstream fitness-related traits in the acoustic parasitoid fly Ormia ochracea. See Dominguez et al. (2025) for details on data collection and analyses.
