Previous studies suggest that a number of factors in relation to mating may reduce female longevity and stimulate egg production and oviposition. However, it is still not clear whether these factors act on these parameters independently or in a collective way. Here we carried out a series of experiments including mating trials and seminal fluid injection to determine the factors responsible for reducing female longevity and stimulating egg production and oviposition in relation to mating in the moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae). Results show that seminal fluid and sperm work collectively to allow females to achieve maximum realized fecundity (number of eggs laid) in E. kuehniella but these factors play different roles in the process and their actions are independent. Seminal fluid signals females to allocate resources to ova, resulting in shorter longevity and greater egg production while eupyrene (not apyrene) sperm in the spermatheca trigger females to lay maximum number of eggs. We suggest that the receptors for seminal fluid signal may be located in the female reproductive tract and haemolymph, and those for sperm signal may be in the spermatheca. Hypotheses that females prolong their longevity by oosorption, physical injuries by males reduce female longevity, and mechanical stimulation by males triggers oviposition, are not substantiated in the present study.
