Reproductive development of lab-reared female plum curculio, Conotrachelus nenuphar, was assessed under different temperature regimes in same- and mixed-sex cohorts. Individuals were fed ad libitum and three individuals were dissected daily for each temperature and cohort type until full maturity was reached. Reproductive structures were dissected and assessed for number of visible oocytes, size of proximal and distal oocytes, and spermatheca development. Oocyte development appears to be temperature-dependent and unaffected by mating status. Developmental thresholds are estimated for the observed parameters.
