Discrimination Methods for Japanese Species of the Genus Morophagoides（Lepidoptera: Tineidae）Injuring Shiitake Mushroom, Lentinula edodes（Agaricales: Tricholomataceae）, Based on the Adults

Abstract

To date, in Japan, several species of the genus Morophagoides Petersen are known to be pests of shiitake mushroom, Lentinula edodes（Berk.）Pegler. Due to close similarities in the wing markings of the species, it is sometimes difficult to distinguish each species based only on external appearance. In order to provide useful information for pest management strategies, taxonomic keys are given to distinguish the seven Japanese species of the genus mainly using wing maculation and male and female genitalia. Furthermore, the six species are also distinguished by standard DNA barcoding.
