Tegolophus hassani

Tegolophus hassani (Keifer)

Taxonomic placing: Acari, Prostigmata, Eriophyoidea, Eriophyidae.

Common name: Olive rust mite.

Geographic distribution: Mediterranean countries, Iran, Iraq, Ukraine.

Host plants: Olive.

Morphology: The mite is spindle-shaped, yellowish, about 0.18 mm in length, with a broad anterior lobe over the rostrum but without dorsal microtubercles. The featherclaw is four-rayed.

Economic importance: The feeding of this mite causes russeting and deformations on the leaves that reduce the quantity and quality of the olives.

LIfe cycle: In Egypt, a generation is completed in about 14 days at 31°C and 80% RH.

Management: A single application of abamectin in the spring controlled the mite in Egypt.

Biological control: In Egypt the phytoseiid Neoseiulus cydnodactylon (Shehata and Zaher) and the stigmaeid Agistemus olivi Romeih attacked T. Hassani.
