| Abstract | ||
| This work was carried out under laboratory conditions to study the biological aspects of predacious mite, Neoseiulus CUCValeliS (Oudemans). This study was investigated under two constant temperatures at 25 and 30°C and 65*SW° RH to clarify its response when fed on movable stages of citrus red mite, Panonychus obi4McGregor). The incubation period averaged 3.8±0.06, 2.57±0.07, 3.2±0.09 and 2.37±0.1 days at 25°C and 30°C for female and male, respectively. The life cycle periods lasted 10.2*0.11, 7.6*0.1, 9.1*0.07 and 6.7*0.2 days for female and male, respectively at the previous temperature. The food consumption of the predator mite N. cucumeds averaged 78.8±0.9, 49.0±0.6 , 95.1±0.53 and 58.5±0.5 prey of P. citri during their life span for female and male ,respectively . | ||
