| Abstract | ||
| The toxicity of seven acaricides (abamectin, amitraz, azocyclotin, fenbutatin oxide, propargite, pyrimidifin and spirodiclofen) to Tetranychus urticae Koch, Panonychus ulmi Koch (Acari: Tetranychidae) and the predatory phytoseiid mites (Neoseiulus fallacis German and Typhlodromus cotoneastri Wainstein) was evaluated in both laboratory and apple orchards in two different sites on the Syrian Coast (Shakrieh- Lattakia and Premmant El-Masheik-Tartous). All tested acaricides were highly toxic to T.urticae and P.ulmi, except spirodiclofen, which was slightly to moderately toxic after lday, and moderately to highly toxic after 7 days in field. For the phytoseiid mites; amitraz, azocyclotin and pyrimidifin were highly toxic in laboratory and field, abamectin was moderately toxic in both laboratory and field, fenbutatin oxide was moderately toxic in laboratory and non-toxic in field, propargite was moderately toxic in laboratory and slightly toxic in field, and spirodiclofen was slightly toxic in laboratory and non toxic in field. | ||
