Abstract

4種類の堅果類(クリ,スダジイ,シラカシ,マテバシイ)を用い,コクゾウムシの発育試験を行った.全ての堅果に対しコクゾウムシは産卵し成虫まで発育した.成虫羽化数や発育日数はクリ,スダジイ,マテバシイの堅果間で大きな差はなかったが,シラカシの堅果は羽化数が少なく,発育日数が長かった.外果皮が無傷な堅果に対してコクゾウムシは産卵できず,次世代の成虫は羽化しなかった.

The developmental period of the maize weevil, Sitophilus zeamais Motschulsky was examined by using four kinds (Castanea crenata, Castanopsis cuspidatan, Lithocarpus edulis and Quercus myrsinaefolia) of acorns. The maize weevil lays eggs and has grown an adult for all acorns. Neither the number of adult emerging nor the developmental period had a big difference among acorns of Castanea crenata, Castanopsis cuspidatan, and Lithocarpus edulis. As for the acorn of Quercus myrsinaefolia, the number of emerging was less than that of other acorns, and the developmental period were longer. The maize weevil was not able to be laid to the acorn with a flawless epicarp, and next generation's adult did not emerge.
