Frequently the infestation levels in the rice storages were very low. The analysis of the factors that influenced the insect populations indicated that the suppression was apparently caused by natural enemies, especially predators. Many ants were captured such as Crematogaster sp.,Tapinoma indicum and Paratrichena longicornis. Xylocoris flavipes, a predacious bug and Withius niger, a pseudoscorpion were also trapped. In addition, the occurrence of intruders like spiders, lizards, etc. was frequently observed in the storage facilities since common rice storage structures in Thailand are widely exposed to such predators from outside. Thus, insect pests, natural enemies, especially predators from outside and host grain form a very unique and balanced ecosystem.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"タイ国11地域の米貯蔵場所（農家倉庫，種子貯蔵庫，精米工場）の貯穀害虫個体群の発生をフードトラップ（籾，玄米，精米500gづつを金属ケージにいれたもの）を用いて，4か月ごとに更新し，一年間調査した。その結果，貯穀害虫の発生の状況は，発生数の少ない制御型と大発生の見られた爆発型に二極化した。それ故， 害虫による被害が意外に低レベルなケースが数多く見られた。害虫個体群の増減に対する作用因子の解析から，制御型は明らかに天敵類，特に補食者が起因していることが示唆された。すなわち，設置トラップには多くのアリ類(Crematogaster spp., Tapinoma indicum, Paratrichena longicornis)，ハナカメムシの一種Xylocorisflavipes，カニムシ(Withius niger)が捕獲された。これらに加えて，貯蔵場所の多くは密封性がないので，本来野外に生息しているクモ，ヤモリ等の侵入補食者も頻繁に観察された。トラップで得られた結果と観察された事象からタイの米貯蔵場所では，貯穀害虫ー天敵類（特に外部侵入補食者）ー貯蔵米の間で，非常にユニークなバランスのとれたエコシステムが形成されているものと考えられる。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-01-09"}],"filename":"jircas_journal1-_1-7.pdf","filesize":[{"value":"818 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_journal1-_1-7","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000089/files/jircas_journal1-_1-7.pdf"},"version_id":"1e853b32-ebed-4a23-9a49-e6c61a7236bd"}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000089","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13407686","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11030483","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"predators","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"parasites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ants","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spiders","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pseudoscorpion","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Role of Natural Enemies in the Regulation of Stored-Product Insect Populations in Rice Storages in Thailand","subitem_title_language":"en"},{"subitem_title":"タイ国の米貯蔵場所における貯穀害虫個体群制御に及ぼす天敵類の役割","subitem_title_language":"ja"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"Role of Natural Enemies in the Regulation of Stored-Product Insect Populations in Rice Storages in Thailand","item_type_id":"40039","owner":"8","path":["1705363447547"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-01-05"},"publish_date":"2024-01-05","publish_status":"0","recid":"2000089","relation_version_is_last":true,"title":["Role of Natural Enemies in the Regulation of Stored-Product Insect Populations in Rice Storages in Thailand"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2024-02-05T02:57:29.062176+00:00"}
