Abstract

Abstract The grain aphid Sitobion avenae is a prolific pest of cereal crops worldwide, controlled effectively with pyrethroid insecticides. However, the classic knock down resistance (kdr) mutation, L1014F on the S. avenae sodium channel gene, has been identified as the cause of the recently observed heterozygous (kdr-SR) resistance in the SA3 grain aphid super-clone. Results indicate that the kdr-SR SA3 clone can survive pyrethroid exposure above twice the normal field rate, continuing to reproduce thereafter. Additionally, the SA3 clone was found to be capable of producing sexual oviparous morphs, able to lay eggs following pyrethroid exposure. This demonstrates that possession of the L1014F mutation does not preclude the capacity to produce sexual morphs. This makes the adoption of an effective resistance management strategy imperative, within a wider integrated pest management (IPM) approach to control grain aphid.

对拟除虫菊酯类杀虫剂产生抗性的野拟蚊(半翅目:蚜虫科)SA3超级无性系在暴露于当前田间剂量的拟除虫菊酯类杀虫剂后保留了性能力和存活的第一个证据

摘要谷物蚜虫是世界范围内谷物作物的一种多产害虫，拟除虫菊酯类杀虫剂可有效防治。然而，最近在SA3粒蚜超级无性系中观察到的杂合性(kdr- sr)抗性是由avenae钠通道基因上的L1014F的典型敲低抗性(kdr)突变引起的。结果表明，kdr-SR SA3无性系在杀虫剂浓度超过2倍的情况下仍能存活，并继续繁殖。此外，发现SA3克隆能够产生有性卵生形态，能够在接触拟除虫菊酯后产卵。这表明，拥有L1014F突变并不妨碍产生有性变异的能力。这使得在更广泛的病虫害综合防治(IPM)方法中采用有效的抗性管理战略势在必行。

期刊介绍： The Irish Journal of Agricultural and Food Research is a peer reviewed open access scientific journal published by Teagasc (Agriculture and Food Development Authority, Ireland). Manuscripts on any aspect of research of direct relevance to Irish agriculture and food production, including plant and animal sciences, food science, agri environmental science, soils, engineering, buildings, economics and sociology, will be considered for publication. The work must demonstrate novelty and relevance to the field of research. Papers published or offered for publication elsewhere will not be considered, but the publication of an abstract does not preclude the publication of the full paper in this journal.
