| Abstract: | The chrysomelid Diabrotica undecimpunctata howardi, which is best known as a pest of maize, has been recorded as ovipositing on soyabean but was not known for certain to be able to complete its development on that food-plant. In greenhouse studies in North Carolina, larval survival, development time, adult emergence and size were compared in populations reared on maize, soyabean and cucumber. Larval survival was low on all the plants. Adult emergence and size were greatest on maize and least on cucumber, and development was also slowest on this plant. On soyabean, adult emergence was significantly lower than on maize and adult size was very similar to that of beetles reared on cucumber, but development time was similar (31.3-33.9 days) to that of beetles reared on maize (31.4-32.2 days). Soyabean thus appeared intermediate in suitability as a larval food-plant. |
