| In order to clarify the structure and diversity of arthropod community in vegetable soybean field in Shijiazhuang, Malaise trap was used in this research to collect arthropods. The arthropod species were identified, the composition, structure of arthropod community and the dynamics of main groups were also studied. The results showed that: A total of 6 927 arthropods belonging to 3 classes, 11 orders, 94 families and 255 species were collected by Malaise trap, among which, 45 were Chilopoda, 31 were Collembola, and 6 851 were insects. In Insecta, the order of quantity from large to small was: Hemiptera＞Diptera＞Coleoptera＞Mycoptera＞Lepidoptera＞Hymenoptera＞Neuroptera＞Orthoptera＞Odonata. The major groups were Cicadellidae, Aphididae, Thripidae, Noctuidae Lathridiidae, Coccinellidae, and Syrphidae. The leaf hoppers, aphids, thrips, nocturnal moths and leaf beetles were the dominant pest populations. Syrphidae and Coccinellidae were the main natural enemies. The arthropod species and number in this vegetable soybean field were far more than that in other fields. Diversity analysis showed that the diversity index, evenness index and richness index of arthropod community structure in vegetable soybean field in Shijiazhuang were all high, indicating that arthropod community had high stability in this area. |
