| Abstract: | Stomach contents of Mogera wogura wogura were studied based on 125 specimens trapped at the Hanno Golf Course, Hanno City, Saitama Prefecture. The contents were sorted into the following food items: animal matters, vegetable matters and others. Number of stomachs containing each food item was given for four seasonal periods, spring (March to May), summer (June to August) , autumn (September to November) and winter (December to February) . The results obtained were as follows: Insects and earthworms were the main foods of the moles. The ocourrence rate of Formicidae (adult) was the highest and Scarabaeidae (larvae) was the second. The number of stomachs containing the larvae of Scarabaeidae was found in winter and spring in plenty, but that of the adults was seen in summer and autumn, and that of the hairs of M.w. wogura as a mass was often found in winter and spring. Namely, because these seasons were breeding seasons of the moles they seemed to fight with each other. And hairs found thin in each stomachs in summer and autumn seemed to be swallowed in case of grooming. All vegetable matters were found as fibers in the stomachs in summer. Sand and soil were found in most of the stomachs. They seemed to be swallowed with other foods, moreover they might have come out of the intestines of earthworms. | | 埼玉県飯能市の飯能ゴルフ場において採集した125個体のアズマモグラの胃内容物を調査した。1. アズマモグラの主要食物は昆虫類と貧毛類であった。2. 昆虫類のうち出現頻度は、アリ科の成虫が最も大きく、次にコガネムシ科の幼虫であった。3. コガネムシ科の幼虫を含む胃は冬と春に、また成虫を含む胃は夏と秋によく認められた。4. 貧毛類を含む胃は冬と春によく認められたが、夏と秋にはあまり認められなかった。5. アズマモグラの毛を含む胃は、とくに冬と春によく認められ、しかもかたまりとして存在していた。この時期は本種の繁殖期にあたるため、モグラどおしの闘争があったと考えられた。そして夏と秋には、わずかの毛が少数の胃内に認められたのみで、グルーミング等によって呑みこまれたものと考えられた。6. 植物質は、胃内にあっては全て繊維状を呈しており、これを含む胃は夏期に多くみられた。7. 大部分の胃内には土砂が認められたが、これは他の食物とともに不意に呑みこまれたと思われるが、土砂の一部はミミズの消化管内のものも含まれていると考えられた。 |
