The amount of 2-methylanthraquinone (MAQ) in teak wood extractives was not related to the feeding deterrents or toxicity, as shown by the no-choice feeding tests conducted using crude extractives containing various amounts of MAQ, MAQ alone, and fractions of crude extractives. As a native pest, the subterranean termite Coptotermes formosanus was more tolerant to the fractions of crude extractives than Reticulitermes speratus, and the mortality observed in C. formosanus was not due to the presence of MAQ.<\/jats:p>","DOI":"10.3390\/insects7040063","type":"journal-article","created":{"date-parts":[[2016,11,8]],"date-time":"2016-11-08T09:58:26Z","timestamp":1478599106000},"page":"63","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Toxicity and Feeding Deterrent Effect of 2-Methylanthraquinone from the Wood Extractives of Tectona grandis on the Subterranean Termites Coptotermes formosanus and Reticulitermes speratus"],"prefix":"10.3390","volume":"7","author":[{"given":"Maya","family":"Ismayati","sequence":"first","affiliation":[{"name":"Graduate School of Life and Environmental Sciences, University of Tsukuba, Tsukuba 305-0872, Japan"},{"name":"Research Center for Biomaterial, Indonesian Institute of Sciences (LIPI), Jl.
