Vigna unguiculata, V. aureus, Peureria phaseoloides and Phaseolus vulgaris were suitable as alternate legume food sources for nymphal development of Acanthomia tomentosicollis Stal. Gentrosema pubescens, Galopogonium mucunoides, Grotolaria juncea and Sphenostylis stenocarpa did not support nymphal development beyond the first in star stage and Glycine max supported A. tomentosicollis only to the fourth-instar stage. Nymphal development was completed in 13-21 days on the various suitable food sources. Nymphal mortality was affected by the type of food source. Weights of freshly-emerged adult males and females were significantly influenced by the legume source of food. The longevity of adults reared on Gajanus cajan and V. unguiculata was not different, but the fecundity of the females reared on the latter plant was significantly higher. Access to free water decreased the rate of development but significantly increased both the fecundity and longevity of females
