贵州省普定县'白旗韭黄'害虫和天敌种类调查OA
Survey of pests and natural enemies in'Baiqi Allium tuberosum'in Puding county of Guizhou province
[目的]探明贵州省普定县'白旗韭黄'田间害虫与天敌昆虫的种类组成及其发生规律,为韭黄害虫绿色防控提供理论支撑.[方法]采用系统田间调查、黄板诱捕和地罐诱集方法,分析'白旗韭黄'田间害虫与天敌种群组成、危害程度、群落多样性及主要害虫的发生规律.[结果]共采集和鉴定小型动物群落22 702头,其中昆虫纲占绝对优势,记录10目62科152种21 359头,占比94.08％.植食性害虫主要集中在实蝇科、蓟马科、蚜科和眼蕈蚊科,以葱蚜、韭菜迟眼蕈蚊和蓟马类为主要害虫.天敌昆虫以瓢虫、茧蜂和草蛉等捕食性种类为主,优势种包括异色瓢虫、龟纹瓢虫、稻红瓢虫和食蚜瘿蚊.不同调查样地害虫种群的发生具有明显的时空差异,优势种群及其发生规律各不相同.韭黄田间昆虫物种丰富度指数呈先升后降趋势,物种多样性和均匀度在7-10月达峰值;其中,葱蚜全年持续发生,韭菜迟眼蕈蚊于11-12月集中暴发.[结论]普定县'白旗韭黄'田间害虫与天敌昆虫种类丰富,葱蚜和韭菜迟眼蕈蚊为主要害虫,其持续或季节性暴发的规律明确,为韭黄害虫预测预报与精准防控提供科学依据.
[Objective]The species composition and occurrence patterns of insect pests and natural enemies in'Baiqi Allium tuberosum'fields in Puding county of Guizhou province were investigated to provide a theoretical basis for eco-friendly pest management strategies.[Method]Systematic field surveys,yellow sticky trap sampling,and pitfall trap collections were conducted to analyze the population composi-tion,damage levels,community diversity,and seasonal dynamics of major pests and natural enemies in'Baiqi A.tuberosum'fields.[Result]A total of 22 702 small arthropod specimens were collected and identified,with Insecta as the dominant class,comprising 21 359 individuals belonging to 152 species from 62 families and 10 orders,accounting for 94.08％of the total specimens.Herbivorous pests were primarily con-centrated in families Tephritidae,Thripidae,Aphididae and Sciaridae,with Neotoxoptera formosana,Bradysia odoriphaga,and thrips identified as the main pests.Natural enemies mainly consisted of predatory groups such as coccinellids,parasitoid wasps,and lacewings,with Harmonia axyridis,Propyle a japonica,Micraspis discolor,and Aphidoletes aphidimyza as the predominant species.Pest populations exhibited notable spa-tial and temporal differences among sampling sites,with distinct dominant species and occurrence patterns.The insect species richness index in chive fields exhibited a first rising and then decreasing trend,with species diversity and evenness reaching their peaks from July to Octo-ber.N.formosana occurred persistently throughout the year,whereas B.odoriphaga showed pronounced outbreaks during November and De-cember.[Conclusion]'Baiqi Jiuhuang'fields in Puding county host a diverse community of insect pests and natural enemies.N.formosana and B.odoriphaga are identified as the major pests,showing distinct patterns of persistent and seasonal outbreaks,respectively.These findings offer a scientific foundation for pest monitoring and precise ecological management strategies for'Baiqi A.tuberosum'production.
