Abstract
About 100 mile2 of an irrigation district in south-western Oklahoma were sampled for Heliothis zea (Boddie). The greatest numbers were found on sorghum, cotton and lucerne. Lucerne was the principal host in June. In July, H. zea was found on all 3 crops, and in August it was mainly on cotton. The distribution patterns fit the negative binomial with k values ranging from 3.00 in sorghum to over 5.00 in lucerne. Parasitism rates were much higher in lucerne (72%) than in sorghum (6%) or cotton (5%). The most common parasites are listed and their distribution patterns given
