文中对分布于山西省境内的９０种核桃害虫的区系特征进行了分析，并将其划分为吕梁山黄土丘陵区、太行山低山沟谷区、太岳山区，中条山区等４个害虫区系，其中核桃黑斑蚜Ｃｈｒｏｍａ－ｐｈｉｓｊｕｇｌａｎｄｉｃｏｌａ（Ｋａｌｔｅｎｂａｃｈ）、岩黄毒蛾ＥｕｐｒｏｃｔｉｓｆａｖｏｔｒａｎｄａＬ．近日污灯蛾ＳｐｉｌａｒｃｔｉａｍｅｌｌｉＤａｎｉｅｌ、姬白灯蛾Ｓｐｉｌａｒｃｔｉａｒｈｏｄｏｐｈｉｌａ（Ｗａｌｋｅｒ）、草履硕蚧Ｄｒｏｓｉｃｈａｃｏｒｐｕｌｅｎｔａ（Ｋｕｗａｎａ）等为西部吕梁山黄土丘陵区的优势种害虫；核桃举肢蛾ＡｔｒｉｊｕｇｌａｎｓｈｅｔａｏｈｅｉＹａｎｇ、核桃缀叶螟ＬｏｃａｓｔｒａｍｕｓｃｏｓａｌｉｓＷａｔｋｅｒ、黄须球小蠢ＳｐｈａｅｒｏｔｒｙｐｅｓｃｏｉｍｂａｔｏｒｅｎｓｉｓＳｔｅｂｂ、木尺 Ｃｕｌｃｕｌａｐａｎｔｅｒｉｎａｅｒｉａ（Ｂｒｅｍｅｒ＆Ｇｒｅｙ）等为东部３个区系的优势种害虫。从营养级的角度将其归并成取食芽叶类、茎叶吸汁类、枝干钻蛀类、蛀果类等４个害虫类群。
In this paper, the floristic characteristics of 90 species of walnut pests distributed in Shanxi Province were analyzed and divided into 4 pests and fauna belts such as Lvliang Mountain Loess Hilly Region, Taihang Mountain Low Mountain Valley Region, Taiyue Mountain Region and Zhongtiao Mountain Region , Among which Chroma-phisjuglandicola (Kaltenbach) and EuproctisfavotrandaL. Recently, Spilarctiamelli Daniel, Spilarctiarhodophila (Walker) and Drosichacorpulenta (Kuwana) were the dominant insect pests in Loess hilly region of western Luliang Mountains. Atrijuglanshetaohei Yang, Locastramus cosalis Walker, Small stupid SphaerotrypescoimbatorensisStebb, Culculapanterinaeria (Bremer & Gray) for the eastern three floristic species of pests. From the trophic point of view it will be merged into the eating buds leaves, stems Suction juice, branches Drilling category, bore fruit and other 4 pest groups.
