Predatory mites and invertebrate-pathogenic fungi are important biological control tools for managing populations of the two-spotted spider mite, Tetranychus urticae , in horticultural field crops. Here, we evaluated strategies for the combined use of a mite-pathogenic strain of Beauveria bassiana and Neoseiulus californicus to suppress T. urticae populations on sweet pepper plants. First, we compared the performance of both b...
