Can harm fruit trees seedlings and planting young trees. In 1990, all the apple trees planted in our hospital were endangered by the leafhopper. Adults in late October from vegetables and weeds transferred to the young apple tree spawning eggs. Strict average per plant up to 200 saplings, spawning density, 10 cm in average 10 egg masses, individual parts as many as 40. As a result, the branches of the victim were covered with bruises and the cold, dry and windy winter and spring led to the death of a large number of branches and young trees, which led to the failure of the park.
