The females of the Sapporo strain had well-developed follicles and a very high feeding rate when the photoperiod was longer than 13 hours. With shorter photoperiods, the females had small undeveloped follicles and a low feeding rate ; thus they were in a state of diapause. In both Nagasaki and Kagoshima strains, the diapausing females appeared at a daylength of 12 and 11 hours, respectively. Thus, the critical daylength varies with the strains, being longer in northern strains than in southern strains. However, Cx. p. quinquefasciatus females were not in a state of diapause even under a short photoperiod of 10 hours. In addition, in 3 strains of Cx. p. pallens the diapausing females were produced under a 10-hour photoperiod at 21℃. After they were exposed to reactivation conditions (photoperiod of 16 hours and 25℃), follicular development, feeding rate and gonotrophic dissociation were examined in the females to elucidate the geographical variation of the diapause of Cx. p. pallens. Most of the females of the Sapporo strain had small follicles, and their feeding rate was low for 1 to 3 days after exposure to the reactivation conditions, but on day 5, the follicles began to develop with an increase of feeding rate, and females became gonoactive. Gonotrophic dissociation was usually observed in the females with low feeding activity for 3 days after exposure to reactivation conditions. On day 5, it became very low with an increase in feeding activity. The females of Nagasaki and Kagoshima strains reactivated more quickly than those of the Sapporo strains. The Kagoshima strain was reactivated the most quickly among the 3 strains. Thus, it is clear that the depth of diapause varies with the strain, being deeper in northern strains than in southern strains. On the other hand, fed females collected in autumn in the field showed a low rate of gonotrophic dissociation and the 1st follicles were in stages IIa and IIb. Individuals with such large follicles were not found in a population of overwintering females. These findings reconfirm that the gonotrophic dissociation does not play an important role in the overwintering ecology of Cx. p. pallens in Japan, that is, the females of this mosquito usually hibernate in the state of diapause without feeding on animal blood.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学医療技術短期大学部紀要 = Bulletin of the School of Allied Medical Sciences, Nagasaki University. 1988, 1, p.19-30","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"78352","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小田, 力"}]},{"nameIdentifiers":[{"nameIdentifier":"78353","nameIdentifierScheme":"WEKO"}],"names":[{"name":"森, 章夫"}]},{"nameIdentifiers":[{"nameIdentifier":"78354","nameIdentifierScheme":"WEKO"}],"names":[{"name":"上田, 正勝"}]},{"nameIdentifiers":[{"nameIdentifier":"78355","nameIdentifierScheme":"WEKO"}],"names":[{"name":"黒川, 憲次"}]},{"nameIdentifiers":[{"nameIdentifier":"78356","nameIdentifierScheme":"WEKO"}],"names":[{"name":"末永, 斂"}]},{"nameIdentifiers":[{"nameIdentifier":"78357","nameIdentifierScheme":"WEKO"}],"names":[{"name":"在津, 誠"}]}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10145685","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09160841","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00019-P00030"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Oda, Tsutomu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Akio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ueda, Masakatsu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurokawa, Kenji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suenaga, Osamu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zaitsu, Makoto"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"iryou01_00_02_t.pdf","filesize":[{"value":"654.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"iryou01_00_02_t.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/19064/files/iryou01_00_02_t.pdf"},"version_id":"6d7f29b5-0405-4224-9cd2-8649c9383e78"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Culex pipiens pallens","subitem_subject_scheme":"Other"},{"subitem_subject":"Culex pipiens quinquefasciatus","subitem_subject_scheme":"Other"},{"subitem_subject":"Culex pipiens complex","subitem_subject_scheme":"Other"},{"subitem_subject":"diapause","subitem_subject_scheme":"Other"},{"subitem_subject":"gonoactivity","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Studies on Imaginal Diapause in Culex pipiens Complex in Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Studies on Imaginal Diapause in Culex pipiens Complex in Japan"}]},"item_type_id":"3","owner":"2","path":["1349"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-07-01"},"publish_date":"2008-07-01","publish_status":"0","recid":"19064","relation_version_is_last":true,"title":["Studies on Imaginal Diapause in Culex pipiens Complex in Japan"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:32:57.230237+00:00"}
