Abstract： Life tables for a laboratory population of Apolygus lucorum (MeyerDür) were constructed at five different temperatures（18,21,24,27 and 30℃）. The results show that developmental rate increased with increasing temperature and that the relationship between temperature and development rate could be simulated by a Logistic model. Developmental temperature thresholds and effective accumulated temperatures for eggs, nymphs, preoviposition and an entire generation were 953, 1232, 1040 and 1107℃ and 14261, 16260, 12313 and 42517 degree days, respectively. The highest nymph survival rate, at 24℃, was 2727% higher than the lowest at 30℃ and the maximum average female fecundity at 24℃exceeded the minimum at 30℃ by 3361 eggs. The intrinsic rate of natural increase (rm) was highest at 24℃. We conclude that 24-27℃ is a suitable temperature range for A. lucorum.
