小板网椿Monostira unicostata(Mulsant et Rey)属半翅目网椿科,是杨、柳树的重要害虫之一。它以成虫和若虫刺吸叶片汁液,同时排泄出灰黑色粘液(呈点状分布)。被害树生长势明显衰弱,极易感染叶部病害及树干腐烂病,并导致其它害虫(吉丁虫、天牛等)发生。受害较重的树木,先是部分枝条枯萎,继而全株死亡。为了有效地控制此虫,我们于1978—1980年进行了观察研究,现将初步结果整理于下。 一、分布及危害 在新疆,小板网椿主要分布在吐鲁番、鄯善、托克逊、沙湾、阿勒泰(北屯)、察布查尔、玛纳斯、哈密、伊吾、疏勒、喀
Monostira unicostata (Mulsant et Rey) belongs to the family Hemiptera, one of the major pests of poplar and willow. It sucks the leaves of adult worms and nostrils juice, while excretion of gray-black mucus (dotted distribution). Victims of tree growth significantly weaker, vulnerable to leaf disease and tree rot disease, and lead to other pests (Jilin bug, celastrus, etc.) occurred. The hardest hit trees, some of the first branches withered, then the whole plant died. In order to control this pest effectively, we conducted an observation study in 1978-1980, and the preliminary results are now sorted out. I. Distribution and Harm In Xinjiang, the small-piled pens are mainly distributed in Turpan, Shanshan, Toksun, Shawan, Altay (Beitun), Chabuchar, Manas, Hami, Yiwu, Cameroon
