Fig. 4.

Length of time (days) for female and male morphs to reach 50 % mortality (LT₅₀) at various constant temperatures. LT₅₀ was calculated for the summer and winter morphs of (a) female D. suzukii, and (b) male D. suzukii when maintained at 1, 5, 10, 20, and 28 °C. Paired t tests were performed on estimated LT₅₀ values (days) for each sex between summer and winter morph at each temperature. Significant differences were indicated by asterisks. (* indicates P < 0.05 and ** indicates P < 0.01)
