实验室取食实验显示，与受体对照相比，取食RNAi棉花叶片的蚜虫的 AgDPPS1 基因表达量受到抑制；随取食时间延长，取食RNAi棉花叶片的蚜虫生存率显著降低。新疆农垦科学院生物技术研究所试验基地中间试验统计结果表明，定殖RNAi棉花叶片的蚜虫数量显著低于受体对照。科研人员收集田间蚜虫，进行Northern blot检测。结果显示，定殖RNAi棉花的蚜虫的 AgDPPS1 ...

Check the undersides of the leaves, and you might find the culprit: large groups of aphids and/or the sticky residue they leave behind after feeding. (Or, on plants with tightly-packed leaves like ...

They spread by producing crawling young which find new areas to colonise then produce young. In July winged forms fly off to infest other plants. Breeding stops in autumn when immature aphids seek ...

近期，中国科学院微生物研究所郭惠珊研究团队在Plant Biotechnology Journal发表题为“HIGS-mediated crop protection against cotton aphids”的研究论文。团队通过在棉花中表达特异性靶向棉蚜AgDPPS1基因的dsRNA，获得了抗蚜虫的棉花新种质。

Prune off affected leaves or stems. This may halt the infestation if you detect it early enough, says Khan. Blast insects off ...
