The key acarine citrus pest in Israel is the citrus rust mite (CRM), Phyllocoptruta oleivora, which is probably the most cosmopolitan citrus pest. In this study we focused on the conservation and augmentation of two indigenous phytoseiids, found to be potential predators of CRM, namely Amblyseius swirskii and Iphiseius degenerans. In order to identify a chemical suitable for Medfly control that is also more selective for these acarine predators we compared the field effects of spinosad to malathion, and found the former to be more selective to A. swirskii than the latter. Field augmentation trials with A. swirskii and I. degenerans yielded significantly higher levels of predators in some of the trials, but had no effect on CRM populations. In unsprayed groves where CRM is under control, these predators subsist on a diet composed of alternate food sources, such as other mites and insect prey, pollen, honeydew and various fungi. We thus believe that habitat management and conservation should become part and parcel of an indigenous predator augmentative program.
