摘要:

【目的】探讨不同害虫管理模式对棉田节肢动物群落多样性的影响,为建立以生态防控为核心的棉田绿色管理模式提供理论依据。【方法】在新疆棉田分别设置生态防控、不防控和化学防控3种管理模式,采用6种方法(目测法、马氏网集虫法、扫网法、黄板诱集法、盆拍法和陷阱法)系统调查棉田节肢动物的种类与数量,分析3种管理模式下棉田节肢动物群落组成的差异、节肢动物各功能群结构特征和多样性特征、节肢动物多样性指数的时序变化以及群落益害比。【结果】3种管理模式下,棉田节肢动物种类和数量各有差异,其中不防控棉田最多(12目61科85 426头),生态防控棉田次之(14目78科75 072头),化学防控棉田最少(10目48科41 237头);半翅目蚜科和缨翅目蓟马科均为3种棉田的优势类群。肉食性类群在生态防控棉田较多(34科),在不防控棉田(23科)和化学防控棉田(20科)相对较少;植食性类群在生态防控棉田较多(30科),不防控棉田次之(26科),化学防控棉田较少(19科)。生态防控棉田的节肢动物物种丰富度在棉花全生育期维持最高水平,多样性指数、集中性和均匀度在3种模式下的变化趋势一致,优势度则与上述3项指标呈相反变化规律,且生态防控对节肢动物物种丰富度和多样性指数的提升作用在棉花蕾期最为显著。此外,生态防控棉田的肉食性类群与植食性类群的个体数比(1﹕0.882)和科数比(1﹕16.825)均为3种模式中最高。【结论】生态防控可增加棉田节肢动物丰度和天敌数量进而控制棉田害虫数量,对调控棉田节肢动物群落结构具有一定的促进作用。

Abstract:

【Objective】The objective of this study is to investigate the impact of different pest management strategies on arthropod community diversity in cotton fields, and to provide a theoretical foundation for establishing an eco-friendly cotton field management approach centered on ecological control.【Method】Three management models—ecological control, no control, and chemical control—were established in cotton fields in Xinjiang. Six methods (visual inspection, Marshall net, sweep net, yellow sticky traps, basin-sweeping, and pitfall traps) were employed to systematically survey the species and abundance of arthropods in cotton fields. Differences in arthropod community composition among the three management models, structural and diversity characteristics of various arthropod functional groups, temporal changes in arthropod diversity indices, and the beneficial-to-pest ratio of the communities were analyzed.【Result】Insect species richness and abundance varied significantly across management models: highest in no control fields (12 orders, 61 families, 85 426 individuals), followed by ecological control fields (14 orders, 78 families, 75 072 individuals), and lowest in chemical control fields (10 orders, 48 families, 41 237 individuals). Hemiptera (Aphidae) and Thysanoptera (Thripidae) were the dominant groups across all three cotton fields. Carnivorous groups were most abundant in ecological control fields (34 families), followed by no control fields (23 families) and chemical control fields (20 families). Phytophagous groups were most abundant in ecological control fields (30 families), followed by no control fields (26 families), and least abundant in chemical control fields (19 families). The species richness of arthropods in cotton fields under ecological control remained at the highest level throughout the entire cotton growth cycle. The trends in diversity indices, concentration, and evenness were consistent across the three treatment groups, while dominance exhibited an inverse relationship with these three indicators. Moreover, the positive effect of ecological control on arthropod species richness and diversity indices was most pronounced during the cotton bud stage. Furthermore, ecological control fields exhibited the highest individual number ratio (1﹕0.882) and family number ratio (1﹕16.825) between carnivorous and phytophagous groups among the three models.【Conclusion】Ecological control can increase the abundance of arthropods and the number of natural enemies in cotton fields, thereby reducing pest populations and positively influencing the structure of arthropod communities in these ecosystems.
