Abstract
Joint effects ofn pre-selection mating system (RA) and percent truncation selected(20%;50%;0%(control) were studed in a 2x2x3 factorial experiment with 5 replicates to examine direct response to selection for pupal weight(PW), and correlated responses for larval weight(LW) and papation time(PT)in tribolium Castaneum.Prior to selction two groups, each with 50 males mated to 100 females were either R-mated for 3 generations.At generation 3,6 lines were formed in each group,one of each selection mating system-selction intensity combinations,and selection began,Each line was maintained during 2 generations of selection by 10 pair-matings.
