Novel Microbial Tools and Tactics for Cutworm Control in Wine Grapes

昆特伦理工大学(KPU)可持续园艺研究所(ISH)和AndermattCanada Inc.将合作探索最有效和可持续的策略来管理冬季攀缘地老虎，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防治相关的入侵多食性地老虎。该项目建立在加拿大农业和农业食品公司(2006-13)和ISH(2018-21)与酿酒葡萄行业合作开发攀爬地老虎害虫的生物解决方案的基础上。四类有希望的生防工具，包括昆虫杆状病毒，两个商业化前的真菌物种(球孢白僵菌和里氏绿僵菌)，昆虫病原线虫，斯氏线虫，以及寄生蜂，赤眼蜂，将被用于制定不列颠哥伦比亚州奥卡纳根山谷葡萄园地瓜线虫复合体的管理策略。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之前的研究。在第一年，将对一个参与的有机葡萄园的地龙复合体进行研究，以了解它们在现场的分布模式和物种组成，并为随后的几年选择试验地。在第二年和第三年，生物防治工具将以协调一致的战略使用，以将生物防治工具应用于适当的害虫阶段和栖息地。通过结合不同种植模式的生物防治工具，并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地老虎种群的计划；从而减少葡萄藤上杀虫剂的使用，并与害虫抗性作斗争。该项目的数据和成果将加速安德马特加拿大公司为加拿大种植者提供的新微生物杀虫剂(S)的注册和商业化。

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.
