|Hypotheses for the main effects of several factors on larval time, pupal time, larval growth rate, pupal mass, chill-coma recovery time, and longevity|
|Selection regime||Inbreeding||Rearing temperature||Sex||Adult temperature||Feeding regime|
|Larval time||No||No||20°C > 27°C||Females > Males||-||-|
|Pupal time||No||No||20°C > 27°C||Males > Females||-||-|
|Growth rate||No||No||27°C > 20°C||Males > Females||-||-|
|Pupal mass||No||No||20°C > 27°C||Females > Males||-||-|
|Chill-coma recovery time||Controls > Selected Lines||No||27°C > 20°C||No||27°C > 20°C||No|
|Longevity||No||No||20°C > 27°C||Females > Males||20°C > 27°C||Control > Starvation|
The hypotheses stated rest on prior results mainly obtained from B. anynana. Selection for increased cold tolerance is expected to have no effect on any trait other than chill-coma recovery time, as no correlated responses to selection were found in a previous study . No inbreeding effects are expected here due to random mating for 14 generations after full-sib matings and thus prior to scoring trait values. Hypotheses regarding temperature, sex and feeding effects are all straight-forward and rest on previous results [e.g. [5,17,20,23,34,36,37]. ‘-‘: Not tested.
