Conteúdo: | Holding temperatures and maturity of 3rd-instar Gasterophilus intestinalis (DeGeer) affec- ted the time required for pupation and subsequent eclosion. As temperature increased the duration of the larval stage decreased. Larvae removed from horses in June developed slower than those removed from horses in July and Aug. Temperatures and humidities af- fected larval pupation and adult emergence. The most favorable environment tested for pupation and adult emergence was 29C and 80-92% RH. larvae held at 5C failed to pupa- te, whereas those held at 38C pupated but did not eclose. Adults emerging from pupae subjected to low humidities during the prepupal stage were malformed. When 3rd instars were removed from the stomachs of horses during Mar. through Aug., the rate of develop- ment and the percent pupation and eclosion increased with the progression date of removal.
