TABLE 1.
The 10 experimental groups (N = 100 per group) subjected to 31 days of cold exposure (5°C) and subsequently maintained in spring‐like conditions (15°C) until death
Experimental groups | Life‐history traits | |
---|---|---|
Mortality | Reproduction | |
Precold mated WM female | X | X |
Precold mated SM female | X | X |
Postcold mated WM female | X | X |
Postcold mated SM female | X | X |
Postcold mated WM male | X | X |
Postcold mated SM male | X | X |
Virgin WM female | X | |
Virgin SM female | X | |
Virgin WM male | X | |
Virgin SM male | X |
For each group, life‐history trait assessment is indicated by a cross (X). Some experimental groups of flies were mated before (precold) or after (postcold) the cold period, while the others were kept virgin. The assay was performed on Drosophila suzukii having either a winter morphotype (WM) or a summer morphotype (SM).
