The materials were collected from Yaga, Nago City (Yagachi Island) ; Shuri, Naha City (Okinawa Island) from 1983 to 1984. 1. The vast number (67%) of nymphs hatched from 0:00 to 10:00 hours of a day. A few (33%) of them hatched during the hours from 10:00 to 24:00. 2. The average egg period was 14 days for the eggs laid in july, 17 days in September and 50 days in February. 3. Most of the eggs (84%) hatched from 10 to 15 days as for the eggs laid in July, 70% hatched from 46 to 55 days in February. 4. The average nymphal period was 48 days in July-September, 200 days in November-July and 87～143 days in September-March. 5. The number of oviposited eggs reached a crest during the period from 11 to 40 days after emergence of the adults. The oviposition lasted just before the death of adults which were about 80 days-old. 6. The average number of eggs laid per female was 976 in 1983, 949 in 1984 and 806 in 1985. 7. the longevity of adults was 54 to 58 days in summer, 70 days in autumn. 8. Field investigations showed that each stage of nymphs as well as adults were observed throughout a year. Fifty to sixty percentages of the whole population (excluding egg) were composed of adults from July to February. However, all developmental stages were found through the year. 9. From the field surveys and laboratory rearing experiments, there is no indication for diapause in this species. This species is poly-voltine and is to be tropical in origin.","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":"1987-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1･2","bibliographicPageEnd":"39","bibliographicPageStart":"31","bibliographicVolumeNumber":"22"}]},"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":"374.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2015385/files/374.pdf"},"version_id":"9fb43bfd-b804-40cf-879f-2138b5c12e0c"}]},"item_title":"琉球列島産鳴く虫に関する研究　第12報　カマドコオロギ　（直翅目：コオロギ科）　の沖縄島における生活史","item_type_id":"15","owner":"1","path":["1642838322541","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-01-29"},"publish_date":"2009-01-29","publish_status":"0","recid":"2015385","relation_version_is_last":true,"title":["琉球列島産鳴く虫に関する研究　第12報　カマドコオロギ　（直翅目：コオロギ科）　の沖縄島における生活史"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:36:16.846832+00:00"}
