Abstract

Preference host is an important factor affecting population dynamics in plant-insect interactions. In this research, the two main phylloxera genotypes found in Argentina (gB and gD) were tested on Vitis vinifera cvs. Cabernet Sauvignon, Malbec, Pedro Giménez, Chardonnay, Cereza, Criolla Grande, and rootstocks 1103 Paulsen, 101-14 Mgt, and SO4 using an excised root assay. Statistical analysis showed that survivorship was affected by the interaction of Cultivar and Time, while hatching was influenced by the interaction of Cultivar and Phylloxera genotype. Cultivar also influenced maximum number of adults, developmental time, as well as gross and net reproductive rates. Phylloxera genotype gB developed faster than gD, however, no other significant differences were found between both genotypes. Principal component analysis showed that Pedro Giménez and Criolla Grande grouped closely with high values of reproduction-related variables, suggesting they are the most preferable hosts, followed by Cabernet Sauvignon; while Cereza, Malbec, and Chardonnay were less suitable. None of the rootstocks allowed the establishment of phylloxera colonies. This study will help improve the biological understanding of phylloxera in Argentina and help develop tools for its management.

阿根廷葡萄根瘤蚜两种基因型在6个葡萄品种和3个砧木上的评价

寄主偏好是影响植物与昆虫相互作用中种群动态的重要因素。本研究对阿根廷葡萄根瘤蚜两种主要基因型(gB和gD)进行了检测。赤霞珠，马尔贝克，佩德罗·吉姆萨梅斯，霞多丽，塞雷萨，克里奥拉格兰德，和砧木1103 Paulsen, 101-14管理，和SO4使用切根试验。统计分析表明，成活率受品种和时间的互作影响，而孵化率受品种和根瘤蚜基因型的互作影响。品种对最大成虫数、发育时间、总繁殖率和净繁殖率也有影响。根瘤蚜基因型gB比基因型gD发育快，但两种基因型间无显著差异。主成分分析表明，佩德罗·吉姆萨梅斯和克里奥拉·格兰德与高值的繁殖相关变量密切相关，表明它们是最理想的宿主，其次是赤眼珠;而塞雷扎、马尔贝克和霞多丽则不太适合。没有一种砧木允许根瘤蚜菌落的建立。这项研究将有助于提高对阿根廷根瘤蚜的生物学认识，并有助于开发根瘤蚜管理工具。

期刊介绍： The American Journal of Enology and Viticulture (AJEV), published quarterly, is an official journal of the American Society for Enology and Viticulture (ASEV) and is the premier journal in the English language dedicated to scientific research on winemaking and grapegrowing. AJEV publishes full-length research papers, literature reviews, research notes, and technical briefs on various aspects of enology and viticulture, including wine chemistry, sensory science, process engineering, wine quality assessments, microbiology, methods development, plant pathogenesis, diseases and pests of grape, rootstock and clonal evaluation, effect of field practices, and grape genetics and breeding. All papers are peer reviewed, and authorship of papers is not limited to members of ASEV. The science editor, along with the viticulture, enology, and associate editors, are drawn from academic and research institutions worldwide and guide the content of the Journal.
