The purpose of this study was to investigate the length of life cycle and horizontal table of life by age of the Nezara viridula var. smaragdula fed on two diets: A (fruits of Phaseolus vulagaris) and B (fruits of Phaseolus vulagaris + bud of Glycine max + cob of Zea mais + seeds of Helianthus annuus). One group of adults received diet A and other diet B under controlled temperature (28 ± 1°C), RH (60/70%), and photophase (14h). One hundred and ten eggs masses (10,200 eggs) were examined and its postembryonic development was observed. The length of life in days and mortality of the immature stages was recorded. Second instars from fifty five eggs masses were fed on diet A and an equal number were fed on diet B. Diet B significantly increased nymphal survival and reduced development time (p<0.05).
