| 摘 要： | 通过探讨春播玉米节肢动物群落结构和时序动态，旨在为玉米田天敌保护利用及玉米害虫的合理防控提供基础资料。采用网捕法和目测法探明春播玉米节肢动物群落结构和时序动态。调查共获节肢动物7632头，隶属3纲12目45科66属70种，亚洲玉米螟Ostrinia furnacalis（Guenée）和玉米三点斑叶蝉Zygina salina Mit为本地区害虫优势种，天敌优势种则为多异瓢虫Hippodamia Variegata（Goeze）、方斑瓢虫Propiylaea quatuordecimpunctata（Linnaeus）、黄褐新园蛛Neoscone doenitzi（Boes.et Str.）、中华草蛉Chrysopa sinica Tjeder和十三星瓢虫Hippodamia tredecimpunctata（Linnaeus）。新疆北部春播玉米田节肢动物群落中植食性亚群落结构特征指数N、H'、J'、D与总群落相近，优势种害虫亚洲玉米螟和玉米三点斑叶蝉的大量发生致使玉米田节肢动物群落特征指数出现显著变化，是影响群落稳定的主要因素。主成分分析表明，捕食性节肢动物物种数、个体数和植食性节肢动物物种数累计贡献率可达61.47%，是影响该地区玉米田节肢动物群落结构变化的主导因子。灰色系统分析则表明，优势种天敌方斑瓢虫、草蛉、黄褐新园蛛种群数量的变化与优势种害虫玉米螟和玉米三点斑叶蝉种群数量的变化关联度最高，其关联度分别为0.7719和0.8778、0.7898和0.8309、0.9637和0.8312。天敌的发生与害虫种群数量的变化具有显著的跟随效应，这为合理保护利用天敌防控玉米害虫具有重要意义。

| Abstract: | The arthropod community structure and temporal dynamics in spring corn fields were investigated with sweeping net and visual observationwith the aim to strengthen the protection and utilization of natural enemies and the rational control of corn pests. A total of 7632 arthropods was collected in the survey, which were identified to 70 species in 66 genera, 45 familiies, 12 orders, and 3 classes. Ostrinia furnacalis (Guenée) and Zygina salina Mit are the dominant pest species in the region. The dominant species of natural enemies are Hippodamia Variegata (Goeze), Propiylaea quatuordecimpunctata (L.), Neoscone doenitzi (Boes. et Str.), Chrysopa sinica Tjeder, and Hippodamia tredecimpunctata (L.). The index N, H', J' and D of phytophagous subcommunity in the spring corn fields in northern Xinjiang was similar to the whole community. Outbreak of the dominant pest species O. furnacalis and Z. salina caused significant changes in the characteristic index of the arthropod community and was the main factor affecting the community stability. The principal component analysis showed that species number and population size of predatory arthropods and species number of phytophagous arthropods cumulatively contributed 61.47% to the community abundance, which was the dominant factors affecting the arthropod community structure dynamics in the corn field. The grey system analysis showed a close connection of the population size of the dominant species of natural enemies P. quatuordecimpunctata, N. doenitzi and C. sinica with that of dominant pest species O. furnacalis and Z. salina, with correlation degree of 0.7719 and 0.8778, 0.7898 and 0.8309, 0.9637 and 0.8312. Our results show that the population dynamics of natural enemies obviously follow those of the insect pests, which is of great significance for reasonable protection and utilization of natural enemies to management corn pests. |
