Conteúdo: | Abstract: Aganaspis pelleranoi (Brèthes, 1924) (Hymenoptera: Figitidae) is a koinobiont endoparasitoid of larvae of species of the genus Anastrepha and of Ceratitis capitata. It is a candidate for use as a biological control agent, as under Þeld conditions, it may reach a parasitism rate of 62%. The objective of this study was to determine the effect of different constant temperatures on biological parameters of A. pelleranoi when parasitizing the larva of Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae), as well as to determine its thermal requirements. The study was conducted in environmental chambers at 18, 20, 22, 25, 28, and 30 +- 1.C; 70 +- 10% relative humidity; and a 12-h photophase. Females maintained at 18 and 20.C produced more progeny than females at other temperatures tested. The longevity of males and females was inversely proportional to temperature, ranging from 49.1 to 3.73 d for females and from 32.1 to 3.8 d for males at temperatures of 18-30.C, respectively. The duration of the biological cycle (egg-to-adult) was inßuenced by temperature, and ranged from 69.1 d at 18.C to 30 d at 25.C. No preimaginal development of A. pelleranoi occurred at 28 and 30.C. The relationship between temperature and the demographic parameters of A. pelleranoi showed a linear effect over the temperature range of 18-25.C. The lower temperature threshold and thermal constant were 11.69.C and 391.70 degree days, respectively.
