中文摘要：甘薯粉虱（B型烟粉虱）可使水果和叶片的色素沉着发生改变。本文比较了有症状和无症状植物组织中类胡萝卜素和叶绿素的含量。研究结果表明，甘薯粉虱的侵染抑制了类胡萝卜素和叶绿素（均通过非甲羟戊酸途径合成）的累积。
外文摘要：The sweet potato whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae) B biotype, induces pigmentation changes in fruit and leaves including tomato-irregular-ripening disorder and squash-silverleaf disorder. We compared carotenoid and chlorophyll content of symptomatic and asymptomatic plant tissue. Symptomatic tissue from tomato fruit had 69% and 79% less lycopene (red pigment) and its precursor phytoene, respectively, than asymptomatic tissue. Heavily silvered squash leaves had 63% and 68% less chlorophyll a and b (green pigments), respectively, than healthy leaves. Squash leaves with silvering also had 42-67% lower levels of the carotenoids, beta-carotene, all-trans-violaxanthin and lutein. These results suggest that infestation by the sweet potato whitefly inhibits the accumulation of carotenoids and chlorophylls which are both synthesized through the non-mevalonate pathway.
