In previous studies plant feeding behavior of plant- and non-plant feeding phytoseiids was never examined directly. Moreover, in these studies the cheliceral morphology of phytoseiids was not associated with their ability to feed on plants. In the present study, we monitored the plant-feeding behavior of Euseius scutalis and Amblyseius swirskii. Only E.(More)
Biological pest control in greenhouse crops is usually based on periodical releases of mass-produced natural enemies, and this method has been successfully applied for decades. However, in some cases there are shortcomings in pest control efficacy, which often can be attributed to the poor establishment of natural enemies. Their establishment and population(More)
The establishment of predatory mites on protected crops is affected by the availability of shelter and alternative food. We suggest that a pollen covered twine, coined here “pollen on-twine”, may provide these necessities when attached to the plant. We evaluated the effect of twine types and two pollen species on the establishment of Euseius scutalis(More)
The citrus rust mite (CRM), Phyllocoptruta oleivora (Acari: Eriophyidae) is a cosmopolitan key pest of citrus, inflicting severe economic damage if not controlled. In Israel, CRM damages all citrus cultivars. International regulation and increasing control failures of CRM led growers to seek sustainable biological control solutions such as acarine(More)
Numerous natural enemies were adopted worldwide for the control of major pests, including exotic phytoseiid species (Acari: Mesostigmata: Phytoseiidae) that had been moved from continent to continent in protected and perennial agricultural systems. However, relatively fewer successes were recorded in perennial agricultural systems. In this manuscript we(More)
Omnivorous arthropods can play an important role as beneficial natural enemies because they can sustain their populations on plants when prey is scarce, thereby providing prophylactic protection against an array of herbivores. Although some omnivorous mite species of the family Phytoseiidae consume plant cell-sap, the feeding mechanism and its influence on(More)
In Israel Rhizoglyphus robini is considered to be a pest in its own right, even though the mite is usually found in association with fungal pathogens. Plant protection recommendations are therefore to treat germinating onions seedlings, clearly a crucial phase in crop production, when mites are discovered. The aim of this study was to determine the role of(More)
