The influence of temperature on egg production by Nezara viridula adults and on the survival and development of nymphs was examined as a possible reason for the relatively low abundance of eggs and nymphs during mid‐summer in southeastern Queensland. High temperatures (27/37 °C) in laboratory studies adversely affected nymphal survival and adult reproduction compared with lower temperatures (10/20 °C and 20/30°C). Nymphal survival to the adult stage was lower under the high temperature regime and none of the resulting adults survived long enough to mate and reproduce. In general, nymphal survival and development and the reproductive ability of adults was similar at the two lower temperature regimes. Since the middle regime approximates summer field temperatures, we conclude that low numbers of N. viridula nymphs during mid‐summer cannot be explained by temperature alone.
