  1. Juvenile survival: average fraction surviving to adulthood; Development time: days from egg to adulthood; Oviposition rate: mean oviposition rate in the first 12 days; Longevity: average age of death. GE: Generation; SR: Selection regime; SL: selection line. Degrees of freedom given are that of the main effect and of the error, respectively; for fecundity:1;8 in all cases. In bolds are given the effects that are significant at the 0.05 level.
