Abstract
Twenty-three central Kansas counties were surveyed for the alfalfa seed chalcid, Bruchophagus roddi Guss. (Hymenoptera: Eurytomidae) and its parasites from August 28 to September 6, 1979. The seed chalcid or evidence of its presence was found in all counties surveyed. Two hymenopterans, Tetrastichus bruchophagi Gahn (Eulophidae) and Liodontomerus perplexus Gahn (Torymidae), were the major parasites found; T. bruchophagi was about twice as common as L. perplex us. Other unidentified hymenopteran and dipteran parasites were occasionally found. In four counties, the seed chalcid was found free of parasites while in five other counties, only one parasite species was found with the seed chalcid. The female to male ratio of the seed chalcid was .6 to 1.
