The southern green stink bug, Nezara viridula (L.), showed variable performance when reared on soybean, Glycine max (L.) Merrill, pods from different stages of plant development. Plant stages examined included R3 (beginning pod), R4 (full pod), R5 (beginning seed), R6 (full seed), R7 (beginning maturity), and R8 (full maturity). Nymphal survivorship was greatest on pods from stages R6 or later, and nymphal stadia were shortest on stage R5. In general, adult longevity, survivorship, oviposition, body weight, and body lipid gain were highest when reared on R7 pods. These results, coupled with previous observations of N. viridula vigor in laboratory colonies and population abundance in fields, suggest that soybean pods at R7 are the most suitable food.
