. Parasitoid development, parasitoid‐induced host mortality and parasitoid progeny emergence were determined at five constant temperatures for Muscidifurax raptor Girault and Sanders, Muscidifurax zaraptor Kogan and Legner, Spalangia earneroni Perkins and Spalangia endius Walker using pupae of the house fly, Musca domestica L., as hosts. At temperatures of 20, 25, 30 and 35 o C the median development times (days from oviposition to adult emergence), respectively, were M.raptor (28.4, 20.7, 14.3, 14.5), M.zaraptor (30.6, 22.8, 14.1, 14.2), S.cameroni (55.6,35.2, 21.8,25.0) and S.endius (52.4, 31.5,16.3,14.6). All species failed to emerge at 15 o C. Using densities of five parasitoids and 100 hosts and a 24 h exposure period, Muscidifurax species oviposited at a greater rate over a wider range of temperatures than Spalangia species. At 15, 20, 25, 30 and 35 o C the mean number of pupae killed per parasitoid were, respectively, M.raptor (1.4, 7.4,10.5, 13.7,14.1), M.zaraptor (0.0, 3.3, 8.9,14.4,15.0), S.cameroni (0.0, 7.8, 11.0, 11.9, 7.4), S.endius (0.6, 4.0, 7.5, 12.0, 11.7), and means of the number of parasitoid progeny per parasitoid were, respectively, M.raptor (0.2, 5.2, 7.9, 11.8, 11.6), M.zaraptor (1.3, 4.4, 8.2, 13.0, 13.7), S.cameroni (0.0, 2.4, 4.7, 5.1, 1.0), S.endius (0.0, 0.9, 3.4, 7.5, 4.9). Development and ovipositional activity in S.cameroni was strongly inhibited at 35 o C. The model by Sharpe & DeMichele (1977) was used to describe temperature‐dependent development and the number of parasitoid progeny produced per parasitoid at temperatures of 15–30 o C in all species.
