Alysia manducator

Some of the early work on parasitoid host location involved non-living host food. Thorpe and Jones (1937) found that Venturia canescens is attracted to the odor of oatmeal. Meat odor was found to be attractive to Alysia manducator and Nasonia Mormoniella) vitripennis (Laing, 1937). Since the source and nature of the responsible chemicals was not determined, it may be that microorganisms were involved.
