M. Kazimirova, INFLUENCE OF LARVAL CROWDING AND MATING ON LIFE-SPAN AND FECUNDITY OFMAMESTRA-BRASSICAE (LEPIDOPTERA, NOCTUIDAE), European journal of entomology, 93(1), 1996, pp. 45-52
Lifespan, preoviposition and oviposition periods of Mamestra brassicae
were unaffected by larval rearing densities and the group effect. Fec
undity of both mated and unmated females was correlated significantly
with pupal weight. Weight-related fecundity was not influenced by larv
al phase variation. Mated females lived, on average, 2 days longer and
had 2.2-3.8 times greater potential fecundity than unmated females. P
ositive fecundity/oviposition period and fecundity/lifespan relationsh
ips existed in mated and unmated females, respectively.
