| Abstract: |
| 【Objective】 The forestry insect Fauna of Coleoptera of semi-arid gully region of the Loess Plateau was investiagated in order to provide evidence for controlling insect pest damage and reasonably managing pest population.【Method】 The forestry insect fauna was regularly investigated using random,continuous net-catch (crown and herbs pest) and five-point (underground pest) method in the region plantations.【Result】 There were forestry insects 182 species (including subspecies),belonging to 129 Genuses,24 Families (Coleoptera) in the region.65 species belonged to the Paleartic Realm,45.77％,48 common species to the Paleartic-Oriental Realm,33.80％;14 species to the Oriental Realm,9.86％ and other 15 species,10.56％.These insects were divided into 6 types of the fauna composition,including carabid beetles,cockchafers,badybug,longicom beetles,leafbeetles and weevils.There were 142 species of forest insects,belonging to 10 Families.【Conclusion】 The forestry fauna main composition of the region are the Paleartic Realm and the Paleartic-Oriental Realm common species of insects (Coleoptera). |
