摘要: Functional responses of deutonymphs the predatory mite,Allothrombium pulvinum Ewing, on eggs and adult females two-spotted spider mite,Tetranychus urticae Koch, were determined in laboratory. Predation experiments conducted lima bean leaf discs over a 24-h period at 25±2°C, 30–50% RH 24L: 0D photoperiod. Prey densities ranged from 10 to 120T. per disc or 2 32 disc.Allothrombium more effective againstT. than its females. The role ofA. integrated biological pest control is discussed.
