摘要
Lifespan, preoviposition and oviposition periods of Mamestra brassicae were unaffected by larval rearing densities and the group effect. Fecundity of both mated and unmated females was correlated significantly with pupal weight. Weight-related fecundity was not influenced by larval phase variation. Mated females lived, on average, 2 days longer and had 2.2-3.8 times greater potential fecundity than unmated females. Positive fecundity/oviposition period and fecundity/lifespan relationships existed in mated and unmated females, respectively.
