It is one of 5 ''Aphthona'' spp. that has been used in Alberta, Canada to control leafy spurge, an invasive plant that reduces pasture quality and degrades natural habitats.〔 Bourchier, R., Erb, S., McClay, A, and Gassman, A. 2001. Euphorbia esula (L.) (Leafy spurge) and Euphorbia cyparissias (L.) (Cypress Spurge) (Ephorbiaceae). In Mason, P. and Huber, S. (Eds). Biological contorol programmes against insects and weeds in Canada 1981-2000. CABI Publishing, Wallingford, UK.〕 ''A. lacertosa'' is native to Eurasia, but was released into North America first in 1990, then more widely in 1997. ''A. lacertosa'' was released specifically to control leafy spurge in wet habitats, where the use of herbicides is restricted and other previous biocontrol efforts had proven ineffective. It has established in Manitoba, Saskatchewan, and Alberta. Adults of this species are black and indistinguishable from ''A. czwalinae'' in the field.〔 (【引用サイトリンク】author = R. Roehrdanz , D. Olson, G. Fauske, R. Bourchier, A. Cortilet, S. Sears )〕 Larvae cause the most damage to the plant by feeding on the roots. In one study, beetle success in controlling leafy spurge was related to the temperature degree days at the control site, with sites with more temperature degree days having more success. 〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aphthona lacertosa」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
