| Abstract: | After the clarification of real species, some of Harmonia axyridis (pallas) bionomiccharacteristics were studied. The results showed that there were 3 or 4 generations a year inTongLiao, it overwinters with adult. Most of the eggs with 3 -4 days of egg stage, the rate ofnatching in 92 Per cent. The carvae go throagh 4 stadia singes. Harmonia axyridis (pallas) isdominant speaes for the natural enemies of phytophthira in TongLiao area. |
