ABSTRACT. The status of the tropical African latrine blowfly Chrysomya putoria (Wiedemann, 1830) is recognized as distinct from the sub-tropical African blowfly C. chlowpyga (Wiedemann, 1818) (Diptera: Calliphoridae).

The biology of C. putoria in laboratory culture is described briefly with emphasis on the differences in development found in three strains of this species from Tanzania, Liberia and Brazil. All three strains were reproductively compatible and there was no evidence of F1 hybrid sterility or hybrid breakdown in subsequent generations. Larval development was significantly faster in the Brazilian strain than in the strain from Tanzania. Sexual maturity was significantly faster in adults of the Liberian and Brazilian strains compared to that found in the strain from Tanzania. This latter strain was affected by the source of protein available as adult food. These differences between strains did not appear to be due to selection in laboratory culture, but rather evidence of the evolution of physiological divergence within a species occupying different geographical regions.
