Here, I investigated which way contributed to the coexistence of leafroller-hunting eumenid wasp species. Resource partitioning and, in addition, differential diet breadths proved to promote species coexistence in this case. First, I analyze the prey records and diet overlap of four eumenid species in a local area. The larger two eumenids hunted similar-sized prey items and had similar potential taxonomic prey uses. But the diet breadth of the subsocial eumenid was much wider than that of the solitary one. As a result, the diet overlap between the two large eumenids decreased. This was because the solitary eumenid attend repeatedly to the same hunting site inhabited by one abundant prey species, while the subsocial one made random hunting. On the other hand, the two medium-sized eumenids partitioned resources according to prey size. Secondly, I related these results to prey choice by several other species of eumenid obtained from literature sources. Ten Japanese common eumenids were divided into four groups according to their prey size.  In each of the four groups, 2 to 3 wasp species differentiated the habitat (1 group) or coexisted by means of differential diet breadths (parallel with differential sociality, 2 groups). 自然界における近似種の共存様式としては，資源分割，干渉型の競争，および先取り型の競争などが知られている．メイガ科やハマキガ科などの葉巻蛾を狩るドロバチ類の共存様式について，資源分割とともに餌種選択幅の広狭が種の共存をゆるす要因になっていることが示唆された．まず，野外におけるドロバチ類4種の餌種構成，および餌種選択の重複度について2年間のデータから検討した．大型の2種のドロバチは餌サイズと餌の分類群のいずれにおいても潜在的な選好性は類似していたが，実際に狩ってくる餌種の構成は，亜社会性ドロバチが単独性ドロバチよりも多様であった．この原因は，単独性種が主選好の餌種を集中的に狩るのに対し，亜社会性種は，ランダム採餌を行なっていることによる．この結果，両種ドロバチの餌種の重複度は低下していた．一方，中型の2種のドロバチ同士は，餌サイズの選好性をちがえていた．次に，日本産の普通種のドロバチ10種について，餌サイズ，餌の分類群，ハチの社会性の程度などを文献資料も用いて比較検討した． 10 種は餌サイズの違いによって 4 つのグループに分れた．各グループ内の種同士を比較すると，生息場所が異なっている場合（ 1 グループ）とともに，生息、場所は類似しているが，餌種選択幅が異なり，かつ社会性の程度が異なっている場合（ 2 グループ）が認められた（残りの1グループの共存機構は不明）．以上より，社会性の程度の差が採餌戦略および餌選択幅の相違をうみ，ひいては種の共存をゆるす一つの機構となっている可能性が示唆された．","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Researches on Population Ecology. 34(1):203-211 (1992)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Itino, Takao","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.jpDebpDe.html"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=A1992JM43400014"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"the Society of Population Ecology"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1007/BF02513531"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/BF02513531","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"個体群生態学会"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0034-5466","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00543238","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Itino,  Takao"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Differential_Diet_Breadths_Species_Coexistence.pdf","filesize":[{"value":"501.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Differential_Diet_Breadths_Species_Coexistence.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/11843/files/Differential_Diet_Breadths_Species_Coexistence.pdf"},"version_id":"00a4b998-9acb-4ab0-9e36-7cbd63681dec"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"COEXISTENCE; DIET BREADTH","subitem_subject_scheme":"Other"},{"subitem_subject":"RESOURCE PARTITIONING","subitem_subject_scheme":"Other"},{"subitem_subject":"EUMENIDAE","subitem_subject_scheme":"Other"},{"subitem_subject":"PREY RECORDS","subitem_subject_scheme":"Other"},{"subitem_subject":"SOCIALITY","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Differential Diet Breadths and Species Coexistence in Leafroller-Hunting Eumenid Wasps","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Differential Diet Breadths and Species Coexistence in Leafroller-Hunting Eumenid Wasps","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1170"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-08-03"},"publish_date":"2011-08-03","publish_status":"0","recid":"11843","relation_version_is_last":true,"title":["Differential Diet Breadths and Species Coexistence in Leafroller-Hunting Eumenid Wasps"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:13:14.500760+00:00"}
