AcariProstigmataTetranychoideaTetranychidae. The oriental spider mite occurs in the eastern Mediterranean countries, in Asia from India to China and in most of Africa.

The oriental spider mite may develop on over two hundred host plants, mostly dicotyledons. The adult female is about 0. The male is reddish, smaller, its hysteronotum is pointed and the legs are longer than the body.

The dorsal setae are short, spatulate and placed on small tubercles. The rounded eggs are pale-brown.

The mites colonize the upper side irientalis leaves whereon their eggs are deposited along the midrib. Each female produces eggs during two-three weeks. The pest raises about 20 annual, largely overlapping generations. The Oriental spider mite is arrhenotokousits sex ratio is usually 0. The oriental spider mite is an important pest of citrusespecially in drier areas.


It is the most persistent citrus pest in Upper Egypt etetranychus an occasional serious pest in the south of Israel. The mites colonize the upper side of leaves where they feed, and their damage develops as yellow-grey stippled spots which cause leaf wilting and drop. Reduced irrigation increases the damage. Lemon trees are more damaged than other citrus species and varieties, whereas oranges are little affected. The oriental spider mite has not yet developed resistance to pesticides.

Thus it may still be be controlled by commonly-used acaricides like amitraz and dicofol, the organotin fenbutatin oxide and even petroleum oils. However, the pest seems to be less susceptible to some of these chemicals, and continuous monitoring for resistance is thus necessary.

The pest is attacked by many indigenous predatory mites of the families Phytoseiidae and Stigmaeidae. The phytoseiid Euseius scutalis appears to regulate this pest in Jordan, but little is known about its specificity and the ability of other predators to reduce pest outbreak populations. orientalos
