Infections by Nosema meslini (Paillot) in adults of the imported cabbageworm, Artogeia rapae (L.) were at epizootic levels at Kahuku, Pearl City and Wahiawa and at enzootic levels at Kahaluu, Waianae, and Waipahu in March 1983. Monthly samples of adults made at Pearl City and Wahiawa showed that the disease was present in these populations at an enzootic or epizootic state throughout the year. The annual cycle of disease in the two areas was almost identical although the physical parameters, temperature, rainfall and elevation in the two areas were quite different. It was apparent that the physical parameters measured did not significantly effect the annual cycle of the disease. The prevalence of the disease indicated that it may be a significant factor in regulation of populations of the imported cabbageworm in Hawaii.
