RESUMO:

Anastrepha fraterculus (Wiedemann, 1830) and Anastrepha obliqua (Macquart) are configured as one of the main pests of world fruit culture, causing economic damage and quarantine barriers. In a climate change scenario, possible changes in the development of these insects can contribute to their distribution and, consequently, to their potential for damage. Our work evaluated the effect of different temperatures over time and on the rate of development of A. fraterculus and A. obliqua in two preferred hosts, respectively. The development time was inversely proportional to temperature, for both species. The rate of development differed between temperatures and between species. A. fraterculus has a higher survival rate of the egg stage at 30ºC (69%), while A. obliqua has a higher rate between 20º and 30ºC (70% and 72%). The survival rates of the larva stage were higher at 25ºC, for both species. However, A. fraterculus was reduced by 15ºC (264 pupae), while A. obliqua suffered a reduction in survival by 30ºC (142 pupae). The pupal stage survival was higher at 20º and 25ºC for both species. However, A. fraterculus suffers reduced survival from this stage when exposed to 30ºC (33 adults), while A. obliqua reduces by 15ºC (49 adults). The development time to adult for both species is shorter in (± 25 days) at temperatures of 25º and 30ºC. The results suggest that A. fraterculus and A. obliqua thrive better in regions of tropical and subtropical climate, an increase in temperature in these regions may cause a reduction in the population of these insects.
