河业省地下害虫区系调查研究

1979—1983年在河北省54个县调查了地下害虫的地理分布和危害程度.从采集的大量昆虫标本中,已初步定出了60个虫种,其中包括金龟子50种,金针虫4种,缕蛄2种,拟地甲2种及麦根蝽象等.根据害虫危害程度和生态条件将全省划分为六个自然区,每个区都有自己的优势虫种.目前,地下害虫发生趋势是:蛴螬十分严重,如华北大黑鳃金龟、暗黑鳃金龟、铜绿丽金龟;金针虫(细胸金针虫)在某些地区具有发展趋势;蝼蛄危害减轻,例如华北蝼蛄.作者认为,河北省低平原区仍是重要防治区,在麦田主要防治华北大黑鳃金龟、细胸金针虫,在玉米田要防治华北大黑鳃金龟、黄褐鳃金龟等,在花生田防治暗黑鳃金龟、华北大黑鳃金龟、铜绿丽金龟.

FAUNA OF SOIL INSECT IN HEBEI PROVINCE

From 1979 to 1983, authors investagated geographical distribution and injury of soil insect in 54 counties of Hebei.60 species were appraised from a lot of insects such as Scavabeidae 50, Elateridae 4 ,Grylltalpidae 2, Tenebrionidae 2,Cydnidae and etc.Distri-bution of Pests and degree of harm are shown by the investagation.According to ecological condition and agricultural peculiarity the whole Proivnce is divided into six natural areas, which have its dominant pests. At present, soil insect trends that,grubs (Holotrichia oblita , Holotrichia morosa , Anomala corpul erta)is very serius and wire worm (Agriot es fuscollis) is developping in some areas, but mole cricket (Gryllotalpa unispina) , for example, is reducing.Authors suggest that the low-lying plain area is to be still important control area: in wheat field Holotrichia oblita, Agriotes fuscollis , in corn field Holotrichia oblita, Anomala exoleta etc,in peanut field Holotrichia morosa, Holotrichia oblita , Anomala corpulenta .
