Abstract:
The representative pear trees were selected to observe the life history and the biological property of the Phenacoccus mespili (Geoffroy) in Korla area.The results showed that there were 3 generations per year in Korla pears，the nymph overwintered under the raise bark，or within crevice-bark.The first generation grow and developd evenly，and the egg’s peak appeared during mid-July，the activity peak of the 1st instar nymph was at later of June；the second and third generations had the overlapped generations，the egg incubation peak of the third generation were in middle late September.There were oocysts when the adults began to lay eggs，and there were 15~315 eggs of one egg mass.The newly-hatched nymph was adept in crawl；Sucking the juice of the branches and trunk by the nymph and adult cause the growth weak of the tree，which usually attached themselves to calyx hollow，and the rate of the commodity fruit was reduced.
