Rearing single pregnant females clarified that this species reproduces\n71\nunisexual offspring and has a preference for fungus as food.\n2. Mating behaviors of B. paupera consisted of a series of stereotyped male\nbehaviors including intermittent wing fanning (WF), walking with a zigzag\napproach (ZA) while continuing WF, abdomen curling (AC) forward beneath\nthe thorax while using his claspers to grab the female abdomen, pivoting 180\ndegrees around body axis and mating occurrence (MO).\n3. Female flies emit volatile sex pheromone from the body surface from the\nlater pupal stage until death. Female cuticular sex pheromone evokes a\nseries of copulating behavior and causes strong chemotaxis flight in males\nirrelative of the dial periodicity.\n4. Male flies begin sexual responses 30 min after adult eclosion and response\nincrease to a maximum at 2 hr after emergence.\n5. Low light intensity depresses male flight activity, but not other locomotor\nactivity, low illumination has no affect on close range mating behavior.\n6. Properly setting of antenna preparations and use of the correct saline allows\nfor recording of electrophysiological responses from tiny antennae of male B.\npaupera based on ordinary amplifier facilities.\n7. n-Aldehydes of C6-C18, 2-ketones of C16-C21 and n-hydrocarbons of\nC10-C26 were identified from female cuticular lipids. 2-ketone of C16-C21\nand n-aldehydes of C6-C9 are also common in male cuticular lipids.\n8. Male antenna responded with comparatively more sensitivity to n-aldehydes\nthan 2-ketones and n-hydrocarbons. In n-hydrocarbons males were more\nsensitive to carbon chains of C11-C12 than longer or shorter ones. Female\nantennae were more sensitive to food related compound s than extracts of a\nmate.\n9. n-Aldehydes of C10-C13, n-hydrocarbons of C11-C13 and other chemicals\nwith structure similar to undecanal elicited typical sex pheromonal\nbehaviors in males. Among these substances undecanal was the most active\ncomponent.\n10. An n-undecanal and n-aldehyde mixture trapped significantly more males\nthan females in preliminary field tests.\n11. Trace amounts of EAD active components important for sex pheromonal\nactivity remain to be identified.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_12_description_45":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"2003","subitem_description_type":"Other"}]},"item_12_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Includes bibliographical references","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_12_dissertation_number_47":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第3338号"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Liu, Yining","creatorNameLang":"en"},{"creatorName":"劉, 益寧","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"35358","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-18"}],"displaytype":"detail","filename":"A3338.pdf","filesize":[{"value":"183.6 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"abstract","url":"https://tsukuba.repo.nii.ac.jp/record/8583/files/A3338.pdf"},"version_id":"d6db22fe-7c61-48cd-9ad9-a4f885a10541"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-18"}],"displaytype":"detail","filename":"1.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tsukuba.repo.nii.ac.jp/record/8583/files/1.pdf"},"version_id":"ac38a3cb-b8f5-48ae-ae7e-c83a3dcc1722"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Chemoecological studies on the reproductive behaviors of the darkwinged fungus gnat, Bradysia paupera (Diptera: Sciaridae)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Chemoecological studies on the reproductive behaviors of the darkwinged fungus gnat, Bradysia paupera (Diptera: Sciaridae)","subitem_title_language":"en"}]},"item_type_id":"12","owner":"1","path":["265"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-07-25"},"publish_date":"2007-07-25","publish_status":"0","recid":"8583","relation_version_is_last":true,"title":["Chemoecological studies on the reproductive behaviors of the darkwinged fungus gnat, Bradysia paupera (Diptera: Sciaridae)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-01T01:04:24.819819+00:00"}
