H.) with the rates of the 30, 20 and 10 predator individualslbit in the treatments A, B and C, respectively. The pest populations were generally low or moderate at the time of the predator releases then decreased gradually until the last inspection. The control treatment was left without any predator. Thepredator release was made by bean leaflets harbouring the predator individuals. The reduction of acarine mite population was 93, 88 and 75 O/O in the first seasons 2003 but reached 99.7, 96 and 94.5 O/O in the second seasons 2004 in treatments A, B and C, respectively...
