“…The numbers of apyrene and eupyrene sperm transferred to the spermathecae were reduced in comparison with the numbers of sperm transferred to the spermatophore at the time of copulation (Seth et al 2002a). The present study demonstrated that the ratio of apyrene to eupyrene sperm was reduced in the spermathecae, which might indicate that degradation of the apyrene sperm is responsible for inducing the activity of the eupyrene sperm, egg maturation and oviposition (Holt & North 1970;White et al 1975;Katsuno 1978;Marcotte et al 2003).…”

“…I considered that each spermatophore represented a single mating as did other authors (Benz 1970;Ferro-and Akre 1975;Hutt and White 1974;Nowosielski et al 1977;and White et al 1975). Female codling moths from field collections during the present study were of unknown ages, but Gehring and Madsen (1963), Geier (1960), and Hamstead and Gould (1950) had determined that females caught in blacklight traps were reproductively young, and those caught in molasses-baited traps were reproductively old.…”

“…Reduced competitiveness can be due to a shortened lifespan, lack of dispersion of the released insects, or loss of synchrony in biological rhythms. Other changes in Lepidopteran species induced by high radiation doses are reduced ability to transfer spermatophores decreased sexual activity, increased mating times, and decreased longevity of sperm (White et al 1975, Souka et al 1975, Hutt and White 1974, Sokolowskl and Ski 1980, Van Steenwyck et al 1979. Another cause of decreased competitiveness in some species is a decreased ability of the males to inseminate the females with eupyrene sperm.…”
