Description

For morphological comparison between the two types of the yellow peach moth, C. punctiferalis (GUENEE), nine quantitative characters were morphometrically evaluated on the male genitalia and female ovipositor. Male moths of the two types were easily distinguishable by the angular and linear characters on the valva and tegumen. Surface microstructures on papilla analis and length of posterior apophysis were good distinguishing characters between the female moths of the two types. Mandible, labrum, epipharynx and pinacular of larvae, and cremaster of pupae were also definitely different between the two types. Based on these morphological differences in adults, larvae and pupae, the Pin-aceae-feeding type of the yellow peach moth was determined as a segregated species of the genus Conogethes from Japan.
