Rearing technology for Neoseiulus fallacis

Neoseiulus placis是一种捕食性螨类，生产出来出售给不列颠哥伦比亚省的农民，用于管理两点蜘蛛螨类。这种生物防治产品用于各种温室和田间种植的农作物上的蜘蛛防治。由于这种捕食者对常用杀虫剂具有抗药性，它可以与其他农业害虫的化学防治程序一起使用。BC浆果种植者目前对这种产品的需求很高，他们正在为斑翅果蝇(SWD，铃木果蝇)使用化学杀虫剂。这些种植者可以在喷洒SWD的同时，同时使用假单胞菌防治蜘蛛。目前以植物为基础的养殖系统不能生产出足够的产品来满足工业需求。为了满足不列颠哥伦比亚省浆果种植者和其他农业用户日益增长的需求，需要一种新的斜纹夜蛾饲养系统。本项目的目标是开发基于人工谷类寄主的稻纵卷叶蝉饲养新技术。在这一新系统上生产假单胞菌将使生物防治生产商能够满足产品需求，并增加该产品的销售。反过来，这将允许进一步实施生物防治，以减少对不列颠哥伦比亚省浆果作物的杀虫剂对环境的影响。

Neoseiulus fallacis is a predatory mite that is produced for sale to British Columbia farmers for management of two-spotted spider mites. This biological-control product is used for spider mite control on a variety of greenhouse and field-grown agricultural crops. Because this predator is resistant to commonly-used insecticides, it can be used alongside chemical control programs for other agricultural pests. Demand for this product is currently high from BC berry growers who are applying chemical insecticides for spotted-wing Drosophila (SWD, Drosophila suzukii). These growers can apply N. fallacis for spider mite control simultaneously while spraying for SWD. Rearing of N. fallacis on its current plant-based system does not produce sufficient product to meet industry demand. In order to meet this increased demand from BC berry growers and other agricultural users, a new rearing system for N. fallacis is required. Our objective in this project is to develop new rearing technology for N. fallacis based on a factitious grain-mite host. Production of N. fallacis on this new system will allow biocontrol producers to meet product demand and increase sales of this product. In turn, this will allow further implementation of biological control which can reduce environmental impacts of pesticides applied for spider mites on BC berry crops.
