烟粉虱是一种重要的入侵害虫，在世界范围内对农作物造成严重危害，已对多种杀虫剂产生抗药性。羧酸酯酶(COE)是一种重要的多功能酶，参与昆虫的生长发育和异源代谢。然而，对烟粉虱COE的系统研究还很少。在此，根据基因组数据库和邻接系统发育树，在地中海地区的烟粉虱(B.Tabaci MED)物种中鉴定出42个不同功能类别的假定COE。COE的表达模式受烟粉虱发育的影响。6种COE的表达水平与烟粉虱成虫对吡虫啉的暴露浓度呈正相关。取食dsBTbe5和dsBTjhe2的烟粉虱成虫死亡率(67.5%)显著高于取食dsEGFP的成虫死亡率(41.1%)。我们的研究结果为烟粉虱COES的功能研究提供了基础，也为研究烟粉虱对吡虫啉的抗性提供了新的视角。
The whitefly (Bemisia tabaci), an important invasive pest that causes severe damage to crops worldwide, has developed resistance to a variety of insecticides. Carboxylesterases (COEs) are important multifunctional enzymes involved in the growth, development, and xenobiotic metabolism of insects. However, systematic studies on the COEs of B. tabaci are scarce. Here, 42 putative COEs in different functional categories were identified in the Mediterranean species of B. tabaci (B. tabaci MED) based on a genome database and neighbor-joining phylogeny. The expression patterns of the COEs were affected by the development of B. tabaci. The expression levels of six COEs were positively correlated with the concentration of imidacloprid to which B. tabaci adults were exposed. The mortality of B. tabaci MED adults fed dsBTbe5 (67.5%) and dsBTjhe2 (58.4%) was significantly higher than the adults fed dsEGFP (41.1%) when treated with imidacloprid. Our results provide a basis for functional research on COEs in B. tabaci and provide new insight into the imidacloprid resistance of B. tabaci.
