“…Sperm continue to develop in the seminal vesicle and deposit after being discharged from the testis 42 . The seminal vesicle is ellipsoid-shaped, situated at the distal 1/3 part of the vas deferens in OFM males, and different from many other species of moth 27 , 43 . Thus, this structure may be closely related with the volume of the spermatophore and re-mating behavior in moths, though more moth species need to be further studied.…”

“…The heavy muscular area of the ductus ejaculatorius simplex can temporarily store mature sperm 31 . The heavy muscular area of the ductus ejaculatorius simplex is specialized with two lateral diverticula in Dioryctria rubella (Lepidoptera: Pyralidae, Phycitinae) 43 , but there are no diverticula in OFM males. The spermatophore of OFM males have a simple, tapered shape without a particular structure, because the diverticulum of the heavy muscular area of the ductus ejaculatorius simplex probably plays an important role in determining the shape of the spermatophore 44 .…”

The oriental fruit moth (OFM), Grapholita molesta (Busck), is one of the dominant fruit-boring pests worldwide. In order to conduct integrated control of OFM effectively, it is important to predict the optimum control period. OFM populations have been monitored either by the number of trapped male moths exposed to sex pheromones or by the number of trapped male and female moths using food traps in orchards. The mating status and development stage of the trapped moths have not been characterized. The present paper studies the anatomical morphology of the OFM reproductive system at different development periods. The results revealed that OFM ovarian development can be divided into six stages. The average daily fecundity of OFM had an excellent positive correlation (r = 0.86) with the percentages of OFM in the egg maturation & oviposition stage, which could be used as an indicator in field population prediction work. There were obvious differences in the morphology of the corpus bursa and the heavy muscular area of the ductus ejaculatorius simplex before and after mating, and these differences could be used to increase the accuracy in predicting the optimum OFM control period.
