THE EFFECT OF SOME ATTRACTANT PLANTS Lysiphlebus fabarum PARASITISM ON GREEN PEACH AHIDS Myzus persicae AND BLACK BEAN APHIDS Aphis fabae.

This study was conducted in the fields of the College of Agriculture and Forestry / the University of Mosul, to identify the effect of plant species that attract parasites, which included (chamomile, coriander, and basil) in increasing the efficiency of the parasite Lysiphlebus fabarum in biological control programs. The results indicated that the chamomile as an L. fabarum attracting plant gave a height average mummy to Myzus persicae and Aphis fabae gave (45.06 ± 8.78, 262.00 ± 12.16) mummy, followed by the coriander plant which showed (35.80 ± 9.15 and 215.00 ± 8.71) mummy for each Myzus persicae and Aphis fabae, respectively. The basil plant showed the least average number of mummies for the two insects (25.78 ± 2.77 and 192.33 ± 13.65) mummy reach of the Myzus persicae and Aphis fabae. However, it was higher than the control upon the Myzus persicae and Aphis fabae (14.71 ± 2.70 and 124.33 ± 22.27) mummy, respectively. The parasitism rate was affected by the increase in the number of mummies, where the chamomile plant showed the highest parasitization rate on Myzus persicae (70.47 ± 4.05) %, followed by the coriander plant (65.90 ± 5.63%), then basil plant (52.77 ±2.24) %, while the control treatment was the least in parasitism (30.38 ± 4.09) %. On the other hand, the percentage of parasitism on Aphisfabae was superior in all treatments of Aphis fabae above the control group (63.29 ± 2.22, 62.16 ± 1.82, 59.66 ± 5.79 and 30.29 ± 1.52).
