大多数植物病毒依靠半翅目媒介生存和传播。有效管理这些昆虫病媒对于尽量减少病媒传播疾病的传播和减少作物损失至关重要。本研究的目的是评价不同内吸杀虫剂对烟粉虱和桃蚜取食行为的影响，以及它们干扰循环病毒传播的能力。所获得的结果表明，一些内吸性杀虫剂具有拒食特性，破坏了病毒通过其昆虫媒介的传播。我们发现，一些测试的杀虫剂显着减少韧皮部接触和汁液的蚜虫和粉虱，活动是密切相关的韧皮部限制病毒的传播摄入。这些内吸性杀虫剂可能在减少由B.烟草属M. persicae，分别。
The majority of plant viruses depend on Hemipteran vectors for their survival and spread. Effective management of these insect vectors is crucial to minimize the spread of vector-borne diseases, and to reduce crop damage. The aim of the present study was to evaluate the effect of various systemic insecticides on the feeding behavior ofBemisia tabaciandMyzus persicae, as well as their ability to interfere with the transmission of circulative viruses. The obtained results indicated that some systemic insecticides have antifeeding properties that disrupt virus transmission by their insect vectors. We found that some of the tested insecticides significantly reduced phloem contact and sap ingestion by aphids and whiteflies, activities that are closely linked to the transmission of phloem-limited viruses. These systemic insecticides may play an important role in reducing the primary and secondary spread of tomato yellow leaf curl virus (TYLCV) and turnip yellows virus (TuYV), transmitted byB. tabaciandM. persicae, respectively.
