食草性昆虫的行为很大程度上受寄主的化学防御和营养品质的影响。一些食草动物已经发展出通过信号通路操纵植物防御的能力。然而，目前尚不清楚食草动物是否可以通过同时减少植物防御和提高植物营养质量而受益。在这里，我们表明，烟粉虱中东-亚洲小1号(MEAM1；以前的“B”生物型)比地中海(MED；以前的“Q”生物型)在卷心菜上表现更好，与MEAM1侵染的卷心菜相比，MEAM1侵染的卷心菜的硫代葡萄糖苷(GS)含量受到抑制，氨基酸供应增加。与MED相比，MEAM1在甘蓝上具有更高的存活率、更高的繁殖力、更高的内禀增长率(Rm)、更长的寿命和更短的发育时间。侵染MEAM1的甘蓝氨基酸含量高于MED。尽管任一生物型的侵染降低了甘蓝中总GS、脂肪族GS、葡萄糖苷、西尼罗林、葡萄糖甘油素和4OH-葡萄糖甘油素的水平，以及相关基因的表达，但MED侵染提高了4ME-葡萄糖甘油素、新葡萄糖甘油素、原谷蛋白和葡萄糖萝卜素的水平。侵染MED的甘蓝GS含量和GS相关基因的表达均高于MEAM1。我们的结果表明，MEAM1通过控制寄主防御和营养品质，在甘蓝上表现出比MED更好的表现。
The performance of herbivorous insects is greatly affected by host chemical defenses and nutritional quality. Some herbivores have developed the ability to manipulate plant defenses via signaling pathways. It is currently unclear, however, whether a herbivore can benefit by simultaneously reducing plant defenses and enhancing plant nutritional quality. Here, we show that the better performance of the whitefly Bemisia tabaci Middle East‐Asia Minor 1 (MEAM1; formerly the “B” biotype) than Mediterranean (MED; formerly the “Q” biotype) on cabbage is associated with a suppression of glucosinolate (GS) content and an increase in amino acid supply in MEAM1‐infested cabbage compared with MED‐infested cabbage. MEAM1 had higher survival, higher fecundity, higher intrinsic rate of increase (r m), a longer life span, and a shorter developmental time than MED on cabbage plants. Amino acid content was higher in cabbage infested with MEAM1 than MED. Although infestation by either biotype decreased the levels of total GS, aliphatic GS, glucoiberin, sinigrin, glucobrassicin, and 4OH‐glucobrassicin, and the expression of related genes in cabbage, MED infestation increased the levels of 4ME‐glucobrassicin, neoglucobrassicin, progoitrin, and glucoraphanin. The GS content and expression of GS‐related genes were higher in cabbage infested with MED than with MEAM1. Our results suggest that MEAM1 performs better than MED on cabbage by manipulating host defenses and nutritional quality.
