Distribution of Cryptolestes of stored products in Kyushu (Col., Cucujidae)

Abstract

The Cryptolestes spp. in Kyushu was surveyed during 1968-1969. A total of 225 samples of wheat, barley, bran, rice, spillage and sweepings were collected from 36 localities in Kyushu. Out of six species of Cryptolestes described from stored products, three species, C. turcicus, C. ferrugineus and C. pusillus, were confirmed. It was pointed out that the dominant species was C. pusillus, a tropical one, which was considered to overwinter indoors in the southern parts of Kyushu.
