The eggs were 5.7mm -6.6mm long and 1.7mm -2.3mm wide just before hatching. 2. Most (96%) of the nymphs hatched from 6:00 to 10:00 a.m. None of them hatched during the hours from 10:00 a.m. to 4:00 a.m. 3. The average egg period was 255 days for the eggs laid during the period from June to July, and 203 days for those laid from August to September. Thus, the egg period was distinctly longer for the eggs laid earlier. The laboratory breedings suggested that the eggs entered the diapause at a certain stage of the embryonic development. 4. The eggs started to hatch from 180 to 190 days after oviposition and about 40% of them hatched during the period from 250 to 260 days after oviposition. 5. The average nymphal period was 107.7 days in 1980, and 110.6 days in 1981. 6. The pre-oviposition period ranged from 10 to 20 days. The number of oviposited eggs reached a crest during the period from 30 to 50 days after emergence of the adults. The oviposition lasted until death of the adults which were 60 to 70 days old. 7. The average number of eggs laid per female was 331 in 1980 and 300 in 1981. 8. The adults survived for 63 days on an average, ranging from 43 to 76 days. 9. The field surverys showed that the young nymphs (less than 15mm in body length) were most abundant in the population from March to May, the middle-sized nymphs (16-25mm) increased in number from April to June and the older nymphs (over 26mm) from May to June, and the adults appeared from June to September. 10. The field surveys and laboratory breeding experiments indicated that this species is possibly univoltine with a certain diapausing-period at the egg stage. The diapause is considered to be originated to avoid the decrease in individual number during the unfavorable season for population growth.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"沖縄農業研究会"},{"subitem_1522300295150":"en","subitem_1522300316516":"Okinawa Agriculture Research Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1344-1477"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00083297"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"沖縄農業"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1984-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1･2","bibliographicPageEnd":"47","bibliographicPageStart":"39","bibliographicVolumeNumber":"19"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"351.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2015368/files/351.pdf"},"version_id":"6e6d53ec-c983-41f4-bfaa-843611c9a304"}]},"item_title":"琉球列島産鳴く虫に関する研究　第6報　オキナワキリギリス　Gampsocleis ryukyuensis　（直翅目，キリギリス科）　の沖縄島における生活史","item_type_id":"15","owner":"1","path":["1642838321331","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-01-29"},"publish_date":"2009-01-29","publish_status":"0","recid":"2015368","relation_version_is_last":true,"title":["琉球列島産鳴く虫に関する研究　第6報　オキナワキリギリス　Gampsocleis ryukyuensis　（直翅目，キリギリス科）　の沖縄島における生活史"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:35:52.654606+00:00"}
