    not lay eggs before the killing of adults with a net; adult peak occurred 80% dichlorvos EC spray, or 40% Diazinon EC 1 000 times, or 2.5% Deltamethrin 2 000 2 500 times, or 10% off EC 2 000 times one hundred grams, or 48% chlorpyrifos EC 1 500

    times; young nymph can be sprayed dimethoate 40% EC, or 50% EC 1 phosphamidon 000 times. Eight Guangchilachan 3 3.1 Distribution and hosts Distributed in Shanxi, Hunan, Henan, Shaanxi, Jiangsu, Zhejiang, Sichuan, Hubei, Guangdong, Guangxi, Yunnan, Fujian and Taiwan. Host for the pomegranate, apple, pear, peach, apricot, tea, tea, mulberry, plum, plum, cherry, jujube, chestnut, hawthorn, citrus, coffee, cocoa, acacia and so on. Features 3.2 hazardous Cheng, nymphs hi twigs and buds in the leaf sap on the piercing; eggs in shoots, the impact of shoot growth, spawning severe than at the dead, weakened tree vigor. Excretions easily lead to disease [3]. 3.3 Occurrence 1 occurred in a generation, the eggs overwinter in the shoots .5 in mid and

    late succession incubation, damage to the July emergence mature late, around mid-August peak for the emergence, adults by more than 20 days after feeding mate in late August to late October for the spawning period, September to mid-October as

    the peak early. diurnal damage, there is a cluster of nymphs, arranged in the branch with a constant head, crawling rapidly, leaping; adult strong force and rapid flight, spawning in the year twigs xylem, the diameter of 4 ~ 5 mm thick branches off at the back of a smooth large eggs, each egg into pieces at 5 to 22, eggs arranged in a vertical hole out, take-out part of

    the hole and covered with wood wool wax hairy white cotton yarn, easily found and identified. Each female can lay 120 to 150, spawning of the adult life of 30 ~ 40 d. 50 to 70 d, to settle after another death. 3.4 Control Points Winter

    pruning, cut off the branches with egg masses to focus on reducing Insect; damage can be spray of chlorpyrifos 48% EC 1 000 times, or 10% imidacloprid WP 3 000 to 5 000 times. As the

    worm body in particular, the nymphs are waxy, which if mixed with the liquid in the oil content of 0.3% to 0.4% of the diesel emulsion or clay diesel emulsion, can significantly increase the control effect [4]. 4 References [1] Feng
