• Abstract:

  This work estimated the developmental mean time of the immature phases (T_imaturos) and the number of generations (NG) of Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) (DS), an exotic pest of economic importance in Brazil, considering thermal requirements in five municipalities in one-year period. The same estimation was performed for the parasitoid Ganaspis brasiliensis (Ihering, 1905) (Hymenoptera: Figitidae), regarding its South Korea (GBCS) and China (GBC) native populations. Estimations for GBCS and for GBC, in raspberry season of Bento Gonçalves/RS (BG), and in strawberry season of Morro do Chapéu/BA (MC) were also performed. T_imaturos obtained for GBCS, GBC, and DS were respectively: a) Petrolina/PE: 22.3 ± 2.1,  22.3 ± 2.4, and 10.9 ± 1.3 days; b) Vacaria/RS: 45.4 ± 11.0, 48.6 ± 12.7, and 22.0 ± 5.6 days; c) Oiapoque/AP: 22.5 ± 11.0, 22.3 ± 0.9, and 11.1 ± 0.30 days; d) Bento Gonçalves/RS: 38.3 ± 10.5,  42.5 ± 15.5, and 19.2 ± 5.4 days; and e) Morro do Chapéu/BA: 31.1 ± 3.2, 32.8 ± 4.0, and 15.3± 1.7 days. In raspberry season, GBCS and GBC in BG presented T_imaturos of 30.2 ± 3.6 and 31.8 ± 3.1 days, respectively, while in the autumn season 35.0 ± 5.7 and 38.5 ± 9.2 days, respectively.  T_imaturos of GBSC and GBC in strawberry seasons in MC were:  a) May-February: 31.6 ± 3.4 and 33.5 ± 4.2 days and; b) May-July: 34.0 ± 2.8 and 36.5 ± 3.2 days; c) November-February: 29.0 ± 0.0 and 30.0 ± 1.0 days. The NG of the evaluated scenarios were determined.
