在反向光周期下，研究了棉铃虫（Helicoverpa armigera, Hubner）雌、雄多次交配对雌性生殖适宜度的影响。通过对单、多交配雌虫的产卵数和寿命的比较，发现雌虫每天的受精卵数与产卵率和产卵率呈正相关，而受精卵数与寿命呈负相关。雄性交配史对雌性繁殖力有显著影响。与未交配雄虫交配的雌虫繁殖力高于与已交配雄虫交配的雌虫繁殖力。这些结果与雌性从多次交配中可能获得的好处有关。
Under a reverse photoperiod, the effects of multiple mating by female and male Helicoverpa armigera (Hubner) moths on female reproductive fitness were investigated. Comparisons of numbers of eggs laid and longevity of singly and multiply mated females revealed a positive relationship between the number of spermatophores received by a female and her oviposition rate in eggs laid per day and fecundity, and a negative relationship between the number of spermatophores and longevity. Male mating history had a significant influence on female fecundity. The fecundity of females mated to virgin males was higher than the fecundity of females mated to previously mated males. These results are discussed in relation to the possible benefits derived by females from multiple mating.
