摘要
南宁市十字花科蔬菜害虫天敌群落物种有70种(类),隶属7目26科。主要有青翅隐翅虫(Paederusfuscipes),长足虻(Dolichopodidae)、小菜蛾绒茧蜂(Cotesiaplutellae)、八斑鞘蛛(Coleosomaoc-tomaculatum)、食虫沟瘤蛛(Ummeliatainsecticeps)、浅斑近微蛛(Eperigonefredeorum)和肖蛸(Tetragnatha)。蜘蛛的种类和数量皆为无公害和常规栽培两类菜地天敌之最。群落的多样性和均匀度偏低,优势种突出。文中揭示了两类菜地天敌群落的相似性及其结构特点和时间动态。认为占两类菜地节肢动物群落物种的53.44%和占个体数量的24.96%的菜地害虫天敌资源,是值得进一步研究和保护利用的自然生物控制因素。
The community of pest enemy of crucifer vegetables in Nanning consisted of 7 orders 26 families 70 species The main components of community included Paederus fuscipes Curtis, Dolichopodae, Cotesia plutellae, Coleosoma octomaculatum, Ummeliata insecticeps, Eperigone fredeorum, Tetragnatha The numbers of species and individuals of spiders are the greatest in the pest enemy community of crucifer vegetable field The diversities and evennesses of that community are low, predominant species are conspicuous After analyzing the community similarity of two kinds of vegetable fields and their features of structure as well as their numeral dynamics according to time, the paper showed that the pest enemy source, accounting for 5344% of the species and 2496% of the individual quantity of the arthropod community in those vegetable fields,was an important natural control factor which was worthy of further studying, protecting and applying
