Amaranth was selected because it followed Beer's law over a wide concentration range, mixed well with the meridic diet, could be extracted in ice-cold water, was not absorbed by larval tissue, had minimal feeding deterrence as well as marginal adverse chronic effects on the larvae, and finally had negligible effect on ingestion rate over a 24 h period. The results indicated that 6th instars consumed 20 times and 5th instars 3 times as much as 4th instars, but when compared on a body weight basis the ingestion rate was similar in all three instars. Temperature and photoperiod influenced the rate of food intake. The application of these findings in assessing defoliation to the forests as well as estimating dosage of pesticides for control of this species are discussed.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320227224192","@type":"Researcher","foaf:name":[{"@value":"Arthur Retnakaran"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0008347X"},{"@type":"EISSN","@value":"19183240"},{"@type":"PISSN","@value":"http://id.crossref.org/issn/0008347X"}],"prism:publicationName":[{"@value":"The Canadian Entomologist"}],"dc:publisher":[{"@value":"Cambridge University Press (CUP)"}],"prism:publicationDate":"1983-01","prism:volume":"115","prism:number":"1","prism:startingPage":"31","prism:endingPage":"40"},"reviewed":"false","dc:rights":["https://www.cambridge.org/core/terms"],"url":[{"@id":"https://www.cambridge.org/core/services/aop-cambridge-core/content/view/S0008347X00034143"}],"createdAt":"2009-12-01","modifiedAt":"2021-10-15","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390001206450311168","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Bioassay with Insects for Bacillus thuringiensis Products-Factors Affecting the Results."},{"@language":"ja","@value":"昆虫を用いるＢａｃｉｌｌｕｓ　ｔｈｕｒｉｎｇｉｅｎｓｉｓ製剤の生物検定―結果に影響する検定条件について―"},{"@language":"ja-Kana","@value":"コンチュウ オ モチイル Bacillus thuringiensis セイザイ ノ セイブツ ケンテイ ケッカ ニ エイキョウ スル ケンテイ ジョウケン ニ ツイテ"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.4039/ent11531-1"},{"@type":"CROSSREF","@value":"10.1303/jjaez.2004.261_references_DOI_UVzrQbdGvKSpFx3VPL0L5oyvPQg"}]}
