Novel Microbial Tools and Tactics for Cutworm Control in Wine Grapes

昆特兰理工大学（KPU）的可持续园艺研究所（ISH）和AndermattCanada公司将合作探索最有效和可持续的管理冬季爬毛虫的策略，重点是入侵的夜蛾，并确定一些相同的策略是否可以有效地对抗相关的入侵多食性夜蛾，圆夜蛾。该项目建立在加拿大农业和农业食品部（2006- 2013年）和ISH（2018-21年）与葡萄酒葡萄行业合作开展的工作的基础上，共同开发针对爬蛾害虫的生物解决方案。四种有前景的生物防治工具，包括昆虫杆状病毒、两种商业化前的真菌物种（球孢白僵菌和栗僵菌）、一种昆虫病原线虫（feltiae steinerma）以及一种拟寄生蜂赤眼蜂（Trichogramma sp.），将被用于制定不列颠哥伦比亚省奥肯那根谷葡萄园的线虫综合体的管理策略。该项目将通过在一个商业葡萄园进行为期三年的田间试验来推进先前的研究。在第一年，将在一个参与的有机葡萄园中研究蛔虫群，以了解它们在该地点的分布模式和物种组成，并为后续年份选择试验田。在第2年和第3年，生物防治工具将在一个协调的战略中使用，以便在适当的虫害阶段和栖息地应用。通过采用不同模式的生物防治工具，针对不同的生命阶段，种植者将有一个以可持续的方式管理切虫种群的计划；从而减少在葡萄藤上使用杀虫剂，并增强对害虫的抵抗力。该项目的数据和结果将加速Andermatt Canada Inc.为加拿大种植者注册和商业化新的微生物杀虫剂。

The Institute for Sustainable Horticulture (ISH), at Kwantlen Polytechnic University (KPU), and AndermattCanada Inc., will partner to explore the most efficacious and sustainable strategy for the management of winter climbing cutworms, with emphasis on the invasive Noctua comes, and determine if some of the same strategiescould be effective against the related invasive polyphagous cutworm, Noctua pronuba. This project builds on work by Agriculture and Agri-Food Canada (2006-13) and ISH (2018-21) in partnership with the Wine Grape industry to develop biological solutions for climbing cutworm pests. Four promising categories of biocontrol tools, including insect baculoviruses, two pre-commercial fungal species (Beauveria bassiana and Metarhizium rileyi), an entomopathogenic nematode, Steinernema feltiae, as well as a parasitoid wasp, Trichogramma sp., will be employed to develop the management strategy for the complex of cutworms in vineyards in theOkanagan Valley of BC. This project will advance previous research by carrying out three years of field trials at a commercial vineyard. In the first year, the cutworm complex at a participating organic vineyard will bestudied to understand their distribution pattern and species composition at the site and to select trial plots for subsequent years. In years 2 and 3, the biocontrol tools will be used in a coordinated strategy to timeapplications to the appropriate pest stage and habitat. By incorporating biocontrol tools with different modes ofaction, and targeted to different life stages, growers will have a program to manage cutworm populations in a sustainable manner; thereby reducing the use of pesticides on grapevines and combating pests resistance. The data and results of this project will accelerate the registration and commercialization of new microbialinsecticide(s) by Andermatt Canada Inc. for Canadian growers.
