Life tables were compiled for two generations of the banded sunflower moth,Cochylis hospesWalsingham (Lepidoptera: Tortricidae), a univoltine pest of sunflower. Mortality of eggs and four instars in sunflower capitula was 8.9% for the 1986–1987 generation and 11.9% for the 1987%1988 generation.Orius tristicolorWhite (Hemiptera: Anthocoridae) preyed upon eggs and some first instars desiccated beneath involucral bracts. Mortality of fifth instars and pupae overwintering in the soil was 98.5% for the 1986–1987 generation and 94.8% for the 1987–1988 generation. Ground beetle (Coleoptera: Carabidae) predation reduced populations of overwintering larvae and pupae by 39.6% in 1986–1987 and 44.0% in 1987–1988.Glypta prognathaDasch (Hymenoptera: Ichneumonidae) parasitism reduced populations by 8.0% in 1986–1987 and 18.2% in 1987–1988. Although approximately 50% of fifth instars were parasitized, most fifth instars were consumed by predators before parasitoids emerged.
