Trap counts and natural infectivity of blue-green sharphooter

Effective disease management hinges on an accurate understanding of the ecological and epidemiological underpinnings of the pathosystem. New epidemics may prompt consideration of whether knowledge gaps or changes to the pathosystem warrant revision of management strategies. Pierce’s disease of grapevines (PD) is highly episodic in coastal Northern California vineyards, with modest incidence in most years punctuated by occasionally severe epidemics. To better understand what was driving a developing epidemic in the region, we revaluated what is known about the ecology and epidemiological role of the dominant vector, the blue-green sharpshooter Graphocephala atropunctata. We monitored vector spatiotemporal dynamics at 32 vineyards over three years, surveyed plant community composition in the adjacent habitat to understand its link to vector recruitment, and quantified patterns of natural infectivity for the pathogen Xylella fastidiosa. Overall, the results were consistent with past studie..., Graphocephala atropunctata monitoring:
 Monitoring for the dominant vector in the region, G. atropunctata, was conducted at 32 commercial vineyards in coastal Northern California, spread throughout the central viticultural regions in Napa and Sonoma counties. The vineyard sites were selected in part to capture variation in acreage, surrounding landscape context, vector abundance, and disease pressure. At each vineyard, we deployed between 6 and 15 yellow panel traps (10.2 x 17.8 cm double-sided yellow panel traps; Seabright Laboratories, Emeryville, CA), depending on vineyard size and shape, for a total of more than 375 unique traps. Traps were distributed in two to three transects per site running from the edge of the vineyard into the interior. At each site we also placed one to three traps on the periphery of the vineyard nearby the closest putative vector source habitat (“vegplot\" traps). Each trap was checked twice per month over the growing season and once a month in the dormant s..., , # BGSS counts

Number of *Graphocephala atropuncata* (“BGSS”) adults caught on more 375 individual yellow sticky traps spread among 32 vineyard sites in Napa and Sonoma counties, California, from March 2016 through November 2018.

“site” denotes the unique identifier of the 32 vineyard sites

“site.type” denotes vineyard sites that were located adjacent to one of three categories of surrounding vegetation: riparian habitat, oak woodland or chapparal, or grassland or other habitat

“trap” denotes the unique identifier for the more than 375 separate yellow sticky traps, whose locations did not move appreciably over the study

“trap.type” denotes whether the trap was located within the vineyard block (“vineyard”) or was located on the edge of adjacent vegetation (“vegplot”) to the vineyard block

“distance” denotes the approximate distance in meters from the trap to the edge of vegetation adjacent to the vi...

有效的病害管理有赖于对病害系统（pathosystem）的生态学与流行病学基础的精准认知。新发流行病害往往会引发思考：是否存在知识空白，或是病害系统发生了变化，因而需要对管理策略进行修订。葡萄藤皮尔斯病（Pierce’s disease of grapevines, PD）在北加州沿海葡萄园呈现高度偶发性特征，多数年份发病率较低，偶会暴发严重流行疫情。为深入解析该区域正在发展的疫情驱动因素，我们重新评估了关于优势媒介昆虫——蓝绿叶蝉（Graphocephala atropunctata）的生态学与流行病学作用的既有认知。我们在三年间对32处葡萄园开展了媒介昆虫的时空动态监测，对周边生境的植物群落组成进行了调查以明确其与媒介昆虫种群补充的关联，并量化了病原菌苛养木杆菌（Xylella fastidiosa）的自然侵染模式。整体而言，研究结果与既往研究相符……

Graphocephala atropunctata 监测：
针对该区域的优势媒介昆虫G. atropunctata的监测工作，在北加州沿海的32处商业葡萄园展开，这些葡萄园分布于纳帕县与索诺玛县的中部葡萄种植核心区域。葡萄园样点的选取部分考虑了覆盖面积、周边景观背景、媒介昆虫丰度以及病害压力的差异。根据葡萄园的规模与形状，每处样点部署了6至15面黄色粘板诱捕器（尺寸为10.2×17.8 cm的双面黄色粘板诱捕器；Seabright Laboratories，埃默里维尔，加利福尼亚州），总计设置了超过375个独立诱捕器。诱捕器按照2至3条样线分布，从葡萄园边缘延伸至园区内部。同时，在每处样点紧邻推测的媒介昆虫源生境的周边植被边缘，设置1至3个诱捕器（"vegplot"诱捕器）。在生长季每月对诱捕器进行两次检查，休眠季每月检查一次……
