A field and laboratory study were conducted to determine the efficiency of ethanolic plant of Matricaria chamomilla and propolis in life performance of the aphid black bean, where the study showed superiority propolis in the prevention of hatch and the peril of the nymphs and adult cumulative rate of (37.46, 70.24, 62.45)%, respectively. While it decreased in the effect of Matricaia chamomilla in the prevention of hatch and the peril of the nymphs and adult cumulative rate of (60.22, 45.51, 52.72)%, respectively. The study also showed a significant superiority of the concentration of 3% of the propolis to prevent hatch and average cumulative peril of nymphs and adult was (10.0, 100.0, 97.70)%, respectively. While the concentration of 3% of Matricaia chamomilla less impact in the prevention of hatch and average cumulative at peril of nymphs and adult was (31.06, 77.73, 77.73)%, respectively .Compare with the control treatment, in which the birth rate and the peril of the nymphs and adult was (96.63, 3.3, 3.3)% to respectively.
The study also showed greater impact by increasing the time period was the third day after treatment of Matricaia chamomilla and a clear role in the prevention of hatch and the peril of the nymphs and adult cumulative rate of (54.12, 49.12, 57.45)%, respectively. While the same time period to propolis gave better effect in the prevention of hatch and decimation nymphs and adult cumulative rate of (30.80, 74.12, 67.45)%, respectively .Compare with the treatment given to control where give rate at a cumulative was (100.0, 3.3, 3.3)%, respectively.
