ABSTRACT
Environment experienced by mothers can influence many of the characteristics of their offspring also apply resource-related maternal effects through differential egg provisioning; we investigated impact of flight on female egg production and longevity in the oriental armyworm Mythimna separata (Walker) and whether this contributed to making difference in considered suite of life-history traits on progeny growth i.e. developmental time, larval and pupal mass. We found that forced flight females had early oviposition with higher fecundities and shorter lifespan, whereas control females had delay oviposition with lower fecundities and longer lifespan. In addition, to these maternal effects, flight stimulated changes in maternal egg provisioning had direct significances on progeny life history traits, progeny from forced flight females had poorer larval and pupal masses but development time was extended. However, offspring from control females had heavier larval and pupal masses with shortened development time. It is possible that an increased of flight during the pre-oviposition and ovipostion period influence the oviposition trend, egg production and lifespan of the next generation in M. separata.
