Abstract
The influence of the entomopathogenic fungus, Isaria fumosorosea Wize PA208 was evaluated against the two-spotted spider mite, Tetranychus cucurbitacearum (Sayed) under laboratory conditions at Plant Protection Research Institute, Sharkia branch, Egypt. Two different application methods; spray and dipping techniques of fungi spores suspension were tested at 25, 30±2˚C and 70±5 % R.H. Mortality percentages increased with an increase of spore concentration, exposure time and temperature degrees using spray compared with dipping technique. LC₅₀ values were 2.14×10⁶and 1.70×10⁴ spores/ml after four and seven days of spray application at 30 ˚C, respectively. On the other hand, LC₅₀values were 8.95×10⁶ and 2.77×10⁶spores/ml after four and seven days of dipping technique at 30˚C, consecutively.
