Abstract: To evaluate the control effect of Harmonia axyridis (Pallas) against aphids on broccoli, the study was carried out by releasing eggs of H. axyridis with 4 different ratio of beneficial to harmfulratios. The results showed that the control effect was best when beneficial to harmfulratio was 1∶10. Under this condition, the control effecacy reached 61.36% in 5 days, and was still at 59.23% after 28 days. The results indicated that the validity of Harmonia axyridis against aphids was better.
