Population dynamics of the citrus oriental mite, Eutetranychus orientalis (Klein)(Acari: Tetranychidae), and its mite predatory complex in southern Spain

Description

Abstract: A survey of Eutetranychus orientalis and its predator mites has been carried out inclementine, lemon and orange groves. The oriental mite, E. orientalis, was a dominantspecies both in lemon and orange groves. Other pest species as Tetranychus urticae andPanonychus citri occurred in low numbers. The most abundant phytoseiids were Euseiusstipulatus and Typhlodromus phialatus, the other predators as Neoseiulus californicus,Phytoseiulus persimilis, Euseius scutalis and Paraseiulus talbii having low densities. Thephenology of E. orientalis took place in autumn, in agreement with the second peak of thepredator E. stipulatus. An effect of E. stipulatus on E. orientalis is probably happening, butabiotic variables are also affecting the populations of this pest mite.
