Distribution All three thrips species are common throughout the eastern United States. Mature larvae form earthen cells within which the pupae form. Seedlings are more susceptible to seed corn maggots during a wet, cold spring in which seed germination is slowed. Early season drought may cause an ordinarily harmless thrips population to become a problem. Reproduction continues throughout the winter at a reduced rate and many generations are produced each year. University of Alaska Fairbanks, Cooperative Extension Service.
