概括

杀虫剂兰巴达-西哈洛特林的次致命剂量影响了棉花,Aphis gossypii,跨越了几代人. 虽然F0一代没有直接影响,但随后的几代人经历了基因表达的改变和身体尺寸的减少,这表明了代际影响.

科学领域:

农业昆虫学农业昆虫学
虫害管理虫害管理虫害管理
杀虫剂毒理学杀虫剂毒理学

背景情况:

在全球范围内,Aphis gossypii是一种重要的农业害虫.
微致命的杀虫剂剂量可能会影响关节动物的繁殖和生理.
兰巴达-西哈洛是一种广泛使用的甲状腺类杀虫剂.

研究的目的:

为了研究一剂Lambda-cyhalothrin (LC30) 的亚致命剂量对Aphis gossypii的影响.
分析F0,F1和F2世代对生命表参数,身体测量和基因表达 (Vg和VgR) 的影响.

主要方法:

对暴露于lambda-cyhalothrin的Aphis gossypii的生命表分析.
定量PCR (qPCR) 用于测量维特洛金素 (Vg) 和维特洛金素受体 (VgR) 的基因表达.
跨世代测量身体长度,宽度和体重.

主要成果:

在LC30度下,没有观察到对F0成人寿命,生育能力或体型的显著影响.
在F0.0中,发现了内在增速 (r) 和有限增速 (λ) 的显著下降,以及平均生成时间 (T) 的增加.
在F1和F2代人中观察到Vg和VgR基因表达升高和体型减小,这表明了代际影响.

结论:

在Aphis gossypii中,Lambda-cyhalothrin的次致命和代际刺激作用得到了证明.
Vg和VgR基因表达的改变与这些次致命效应密切相关.
研究结果为了解间接影响和制定防虫剂耐药性管理策略提供了基础.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
