Eutetranychus orientalis (Klein) (Tetranychidae) is a worldwide polyphagous mite causing economic damage to several crops. A laboratory experiments was carried out to evaluate the pathogenicity of two entomopathogenic fungi, Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin, on E. orientalis at three spore concentrations (10⁶, 10⁷, and 10⁸ conidia ml^-1). Probit analysis indicated that B. bassiana was significantly effective and more virulent (LC₉₀ = 1.34×10⁸ conidia ml^-1) than M. anisopliae (LC₉₀ = 2.46×10¹¹ conidia ml^-1), with relative toxicity of 100: 0.2. Toxicity of two essential oils: neem (Azadirachta indica A.Juss. (Meliaceae) and caraway, Carum carvi L. (Apiaceae) against E. orientals was also evaluated at concentrations of 0.125, 0.25, 0.5, and 0.75%. Based on LC₉₀, caraway oil caused higher mortality percentage of E. orientalis females than neem oil after 72 h (i.e., LC_{90 =} 0.198 and 0.753%, respectively) with relative toxicity of 100: 26.30. Oviposition deterrent index increased as concentration increase. It was highest for caraway as 59.91 and 39.2% for neem at concentration of 0.75%. Repellency effect increased as oil concentration increase, and decreased as time increase. Environmentally suitable options for bio-control of E. orientalis might consider the obtained results.
