The current study investigated the influence of temperature on the biological and reproductive aspects of the bean bruchid beetle, Acanthoscelides obtectus (Coleoptera: Bruchinae), in common bean (Phaseolus vulgaris cv. Carioca) under laboratory conditions. To determine thermal constants (fecundity, lifespan and seed consumption), we examined egg-to-adult development under five constant temperatures (16 e32 C). The Briere-1 model best explained the relationship between temperature and developmental rate, providing lower, upper and optimal thresholds of 11.1, 36.1 and 30.3 C, for both sexes. The thermal constant for total insect development was 687.5 degree-days. Developmental time from egg to adult decreased with increasing temperature >20 C. Increasing temperature reduced adult lifespan and increased fecundity over the range 24e28 C. Adult emergence was maximized over the range 20e28 C, but prolonged at 16 C and shortened at 32 C, resulting in fewer emerged adults overall. Beetles consumed less at 28 C, whereas their dry weight was not influenced by the temperature range tested here. These results provide useful knowledge on the biology and thermotolerance of this Brazilian population of A. obtectus in stored beans. |
