Development of a pheromone-based monitoring system for the goosefoot groundling moth, a pest of quinoa in western Canada

藜麦（Chenopodium Quinoa）是一种越来越受欢迎的作物，由于其高蛋白和矿物质含量，健康益处和无麸质特性。在加拿大，市场需求导致藜麦种植迅速增加，远远超出其传统范围，并导致北方藜麦公司的发展。在增加繁殖和产量的同时，NorQuin和相关的藜麦生产商也面临着越来越大的害虫压力，特别是来自鹅足地蛾（Scrobipalpaatriplicella）的压力。这种害虫在早春季节袭击植物的茎，在晚些时候袭击种子，造成生产上的双重损失，使产品滞销。萨斯喀彻温省虫害严重的田地遭受了高达100%的作物损失。为了更好地对该害虫进行监测和管理，本项目将对无尾小蠊自然产生的雌性信息素进行鉴定，开发基于信息素的诱捕器监测系统。有了这些工具，我们就可以制定降低这一有害物种管理风险的战略，同时尽量减少杀虫剂的使用。

Quinoa (Chenopodium quinoa) is a crop growing in popularity due to its high protein and mineral content,health benefits and gluten-free characteristics. In Canada, market demand has led to rapidly increasingcultivation of quinoa well beyond its traditional range, and the growth of the Northern Quinoa Corporation.Concurrent with this increased propagation and production, NorQuin and associated quinoa producers haveencountered increasing pest pressures, particularly from the goosefoot groundling moth, Scrobipalpaatriplicella. This pest attacks stems of plants in early season, and seeds later in the year, producing twofoldlosses in production and making products unmarketable. Heavily infested fields in Saskatchewan haveexperienced up to 100% crop losses. For NorQuin to better monitor and manage this pest species this projectwill identify the naturally-occurring female sex pheromone of S. atricplicella for development of apheromone-based trap monitoring system. By having such tools in place, we can develop reduced-riskstrategies for management of this pest species while minimizing application of insecticides.
