Abstract

Field experiments were conducted to determine the establishment and the effectiveness of certain predatory mites in controlling spider mites in raspberry grown under high tunnels. First, the efficacy of Neoseiulus fallacis and N. californicus releases combined with Phytoseiulus persimilis was compared to an acaricide (clofentezine). Weather and low release rates being unfavourable to predator establishment, release strategies were not as effective as the acaricide. Second, the effect of adding an artificial mist on the establishment of P. persimilis was measured. Control was achieved more rapidly by treatment with artificial mist, but the difference in prey and predator density was not significant. Third, a population dynamics model was developed and calibrated with the aim of better understanding spider mite dynamics under tunnel production. The model fits the field data well, is useful for sizing up the impact of different parameters on the population dynamic and shows that temperature is a critical parameter in the management of spider mites.

植物螨（蜱螨螨科）释放对隧道高产覆盆子螨的防治效果及对mcdanieli叶螨（蜱螨科）种群模型的启示

通过田间试验，研究了几种捕食性螨的建立及其对高隧道树莓中蜘蛛螨的防治效果。首先，将fallacus新绥螨和加利福尼亚新绥螨与persimilphytoseiulus联合释放的效果与杀螨剂（氯芬替嗪）进行了比较。天气和低释放率不利于捕食者的建立，释放策略不如杀螨剂有效。其次，测定了添加人工雾剂对紫杉成虫的影响。人工雾剂防治效果较好，但捕食性和捕食性密度差异不显著。第三，为了更好地了解隧道生产条件下的蜘蛛螨种群动态，建立了种群动态模型并进行了校正。该模型与现场数据拟合较好，有助于估计不同参数对种群动态的影响，表明温度是管理蜘蛛螨的关键参数。

期刊介绍： Biological control is an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies. The aim of Biological Control is to promote this science and technology through publication of original research articles and reviews of research and theory. The journal devotes a section to reports on biotechnologies dealing with the elucidation and use of genes or gene products for the enhancement of biological control agents. The journal encompasses biological control of viral, microbial, nematode, insect, mite, weed, and vertebrate pests in agriculture, aquatic, forest, natural resource, stored product, and urban environments. Biological control of arthropod pests of human and domestic animals is also included. Ecological, molecular, and biotechnological approaches to the understanding of biological control are welcome.
