Abstract

Grapevine leafroll disease (GLD) is the most common and economically destructive grapevine viral disease in South African vineyards and throughout the world. There are many GLD-associated virus variants with Grapevine leafroll-associated virus 3 (GLRaV-3) being the main causative agent of GLD. The vine mealybug, Planococcus ficus, is the most widespread and problematic vector of GLRaV-3. Roguing, pesticides and sanitary measures are common control strategies used in South African vineyards. In this paper, we propose an age-structured mathematical model for the transmission of (GLRaV-3) by Planococcus ficus in the South African context. The model is investigated in terms of the transmission thresholds and control strategies. A simplified model is used to shed light into the qualitative dynamics of transmission and assess the effectiveness of roguing as the main control strategy for GLRaV-3 spread.

葡萄粉蚧传播葡萄卷叶病毒3型的数学模型研究

葡萄叶卷病(GLD)是南非葡萄园和世界各地最常见和最具经济破坏性的葡萄病毒性疾病。glld相关病毒有许多变异，其中葡萄叶相关病毒3 (glav -3)是glld的主要病原体。葡萄粉蚧(Planococcus ficus)是glav -3最广泛和最具问题的载体。除草、杀虫剂和卫生措施是南非葡萄园常用的控制策略。在本文中，我们提出了一个年龄结构的数学模型(glrav3)的传播Planococcus ficus在南非的背景下。从传输阈值和控制策略两个方面对该模型进行了研究。采用简化模型揭示了传播的定性动力学，并评估了roguing作为glav -3传播主要控制策略的有效性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
