Evaluation of Six oils along with Lecanicillium lecanii (= Verticillium lecanii) (Zimm.) Zare & W. Gams (LlMO2) conidia to form micro emulsion formulation and Compatibility of oils with L. lecanii were also tested in the laboratory and bioassay in the laboratory revealed that, LT₅₀ of Eucalyptus oil +Lecanicillium lecanii (E+L), Pungam oil+Lecanicillium lecanii (P+L), Neem oil +Lecanicillium lecanii (N+L), Mustard oil +Lecanicillium lecanii (M+L), Clove oil +Lecanicillium lecanii (Cl+L) and Castor oil +Lecanicillium lecanii (Ca+L) formulations against Phenacoccus solenopsis population were 106.95, 59.15, 54.52, 73.74, 85.28 and 103.90 hours, respectively. The testing of oil formulations against Paracoccus marginatus revealed that, LT₅₀ of (E+L), (P+L), (N+L), (M+L), (Cl+L) and (Ca+L) formulations were 113.43, 66.37, 54.52, 75.47, 89.78 and 110.12 hours, respectively. Oil formulation revealed that, LT₅₀ of (E+L), (P+L), (N+L), (M+L), (Cl+L) and (Ca+L) formulations against Maconellicoccus hirsutus population were 103.01, 60.51, 53.19, 69.36, 83.17 and 97.77 hours, respectively. The LT₅₀ of (E+L), (P+L), (N+L), (M+L), (Cl+L) and (Ca+L) formulations assessed against Ferresia. virgata population were 100.55, 62.94, 52.20, 70.88, 89.54 and 100.22 hours, respectively. Neem oil +Lecanicillium lecanii (N+L) combination showed effective against Phenacoccus solenopsis, Paracoccus marginatus and Maconellicoccus hirsutus.
