The investigation were made during 1965, at Ohgimi, Northern area of Okinawa Island. Pineapple plant of the field has not been subjected to pest control since 1962. Population of the injurious insects and predators were measured by the total number of individuals found on 20 plants. The succession of structure of insect community in pineapple field was summarized as follows: Dia・Pse・(Col・Car)-association from January to July. Pse・Dia・(Car・Col・Dro)-association from August to December. Population of pineapple red scale, Diaspis bromeriae Kern. increase in the period of March to May, and it decrease from June. The most important factor in the later case was the increase of predators. The peak of the occurrence of red scale was found from April to May. Population of pineapple mealy bug, Pseudococcus brevipes Ckll increase in the period of March, occurred in a small number in April, May, June, and early July. The most important factors in the later case was the increase of predators and much rainfall. The peak of the occurrence of mealy bug was found from September to October. One of the important factor in this case seems to be concerned to mature of fruit as a good food for mealy bug. Four predators of mealy bug, Pseudoscymnus kurohime, P. quinq epunctalus, Horniolus okinawensis, and Cryptogonus obriculus were found in large number in April, May, June and July. A predator of red scale, Stictobura sp. was found in large number from May to June. Two Ants, Technomyrmex albipes and Paratrechina bourbonica were found large number during three periods of later part of March to April, August to early September and later part of October, but they were found few in the rainy season.", "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": "1966-12", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "2", "bibliographicPageEnd": "29", "bibliographicPageStart": "21", "bibliographicVolumeNumber": "5"}]}, "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", "download_preview_message": "", "file_order": 0, "filename": "157.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2015203/files/157.pdf"}, "version_id": "41cef343-f93e-4ac6-9014-50c726543501"}]}, "item_title": "パインアップルの害虫防除に関する基礎的研究　第2報　主要害虫および天敵類の年間個体数変動", "item_type_id": "15", "owner": "1", "path": ["1642838312941", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002015203", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-01-29"}, "publish_date": "2009-01-29", "publish_status": "0", "recid": "2015203", "relation": {}, "relation_version_is_last": true, "title": ["パインアップルの害虫防除に関する基礎的研究　第2報　主要害虫および天敵類の年間個体数変動"], "weko_shared_id": -1}
