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.

新小绥螨是一种捕食性螨，生产后销售给不列颠哥伦比亚省农民，用于管理双斑叶螨。这种生物防治产品用于控制各种温室和田间种植的农作物上的叶螨。由于这种捕食者对常用的杀虫剂有抗药性，它可以与其他农业害虫的化学控制计划一起使用。目前，BC省浆果种植者对该产品的需求很高，他们正在对斑翅果蝇（SWD，Drosophila suzukii）使用化学杀虫剂。这些种植者可以施用N.在进行社会福利署喷洒的同时，饲养N.然而，目前以植物为基础的系统不能生产足够的产品来满足工业需求。为了满足BC省浆果种植者和其他农业用户不断增长的需求，一种新的N. fallback是必需的。本项目的目的是开发新的养殖技术。以一种拟谷螨为宿主的秋螨。生产N。这个新系统的谬误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量。反过来，这将允许进一步实施生物控制，从而减少用于BC浆果作物上的蜘蛛螨的农药对环境的影响。
