モモシンクイガ雌成虫の交尾回数と産卵

抄録

Studies of Carposina sasakii, a polyandrous insect, were conducted to investigate the effects of female mating frequency on adult longevity and fecundity. Most females began to copulate on the day of adult emergence at 24℃. Multiple mating occurred in both cases where a female was paired with a different male every day and where a female was paired with a single male continuously. The number of spermatophores received by a female varied from 0 to 3 with pairing periods of 0 to 8 days. An increased number of spermatophores in females did not result in extended adult longevity. There was no significant difference in fecundity between females with one and two spermatophores, whereas females with no spermatophore laid significantly fewer eggs.
