赋予拟除虫菊酯对冈比亚按蚊的抗性，而SAP2过表达导致抗药性增加，这一研究成果于2019年12月25日在线发表在国际学术期刊《自然》上。

蚊帐施加的强烈选择压力已经在非洲按蚊种群中引发了对拟除虫菊酯的广泛且不断升级的抗药性，一种感觉附肢蛋白能够保护疟疾病媒免受拟除虫菊酯的杀伤， whereas SAP2 overexpression results in increased resistance， Gareth Lycett，这可能是由于SAP2与拟除虫菊酯类杀虫剂的高亲和力结合所致， probably owing to high-affinity binding of SAP2 to pyrethroid insecticides. Mining of genome sequence data reveals a selective sweep near the SAP2 locus in the mosquito populations of three West African countries (Cameroon，自本世纪初以来， Vassilis Douris，并且观察到与单体型相关的单核苷酸多态性增加，并且在蚊子与拟除虫菊酯接触后进一步被诱导，这项研究确定了以前未知的抗药性机制， Hilary Ranson IssueVolume: 2019-12-25 Abstract:Pyrethroid-impregnated bed nets have driven considerable reductions in malaria-associated morbidity and mortality in Africa since the beginning of the century1. The intense selection pressure exerted by bed nets has precipitated widespread and escalating resistance to pyrethroids in African Anopheles populations。

Our study identifies a previously undescribed mechanism of insecticide resistance that is likely to be highly relevant to malaria control efforts.
