Abstract

Abstract An accurate and efficient sampling method is an important tool for insect pest management because it allows for consistent measurements across many samples. There are currently no proposed standardised sampling plans or spray thresholds for the aphid Ericaphis fimbriata Richards (Hemiptera: Aphididae) on highbush blueberry (Vaccinium corymbosum Linnaeus) in British Columbia, Canada, despite it being the primary vector for blueberry scorch virus (BlScV). A standard sampling plan for this pest would allow for rapid and consistent measurements of aphid abundance in commercial fields and would allow for more detailed study of the relationship between aphid abundance, damage, and the spread of BlScV. Binomial sampling plans use the presence:absence of a pest within a sample unit to estimate the proportion of infested sample units. Pest density (proportion of measured samples with individuals present) is linked to abundance (number of individuals), and the relationship between these two measures can be modelled mathematically. In the present study, we collected data on aphid density and aphid abundance in six varieties of highbush blueberry grown in the Fraser Valley, British Columbia. These data were used to construct a distribution-free binomial model that, when given a measure of aphid density, can predict aphid abundance within a given sample.

用二项抽样法测定商品高丛蓝莓中蓝莓蚜密度
一种准确、高效的采样方法是害虫管理的重要工具,因为它允许在许多样本中进行一致的测量。加拿大不列颠哥伦比亚省高丛蓝莓(Vaccinium corymbosum Linnaeus)上的蚜虫(半翅目:蚜虫科)是蓝莓焦病毒(BlScV)的主要媒介,但目前还没有提出标准化的采样计划或喷雾阈值。这种害虫的标准抽样计划将允许快速和一致地测量商业领域的蚜虫数量,并允许更详细地研究蚜虫数量、损害和BlScV传播之间的关系。二项抽样计划使用样本单位内是否存在有害生物来估计受感染样本单位的比例。害虫密度(有个体存在的测量样本的比例)与丰度(个体数量)有关,这两个测量之间的关系可以用数学模型来模拟。在本研究中,我们收集了在不列颠哥伦比亚省弗雷泽河谷种植的6种高丛蓝莓的蚜虫密度和蚜虫丰度的数据。这些数据被用来构建一个无分布的二项模型,当给定蚜虫密度的测量时,可以预测给定样本内蚜虫的丰度。

期刊介绍: French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
