摘要:

【目的】研究新疆哈密地区枣园昆虫结构类群和时序变化,分析害虫和天敌的发生动态,为害虫综合防控提供科学依据。【方法】采用网扫法和马来氏网获取昆虫标本,运用多样性指数等统计分析哈密地区枣园内昆虫群落结构及其多样性。【结果】共获得昆虫样本23 898头,隶属于9目74科,以膜翅目(32.43%)、双翅目(31.08%)和半翅目(12.16%)为枣园昆虫群落优势类群;枣园8月中旬昆虫数量最多(3 484头),群落多样性指数在1.80~3.01,8月中旬科级丰富度最高(55科),群落均匀度指数在0.53~0.77,群落优势集中指数在0.08~0.30。枣园主要害虫有蚜科、粉虱科、蓟马科和瘿蚊科,主要天敌有蚜茧蜂科、赤眼蜂科、缨小蜂科和草蛉科。【结论】新疆哈密地区枣园昆虫群落多样性指数、均匀度指数和丰富度指数较高,三者呈一致趋势,哈密枣园昆虫群落具有较高稳定性。

Abstract:

【Objective】 This study aims to investigate the dynamics of pests and natural enemies by investigating the structural taxa and temporal changes of insects in jujube orchards in Hami Xinjiang in the hope of providing important help for the forecast and control of major pests, and basic data and scientific basis for integrated pest prevention and control.【Methods】 Insect specimens were obtained by net sweeping method and Malaise trap.The structure and diversity of insect communities in jujube orchards in Hami were statistically analyzed by using diversity indices.【Results】 A total of 23,898 insect samples were collected which belonged to 9 orders and 74 families.Hymenoptera (32.43%), Diptera (31.08%) and Hemiptera (12.16%) were the dominant taxa in the date garden insect community.The maximum number of insects in the jujube orchard was 3,484 in mid-August, and the insect community diversity index ranged from 1.8-3.01, and the richest degree in mid-August (55 families), the evenness index ranged from 0.53-0.77, and the dominant concentration index ranged from 0.08-0.30.The main pests in jujube orchard were Aphididae, Aleyrodidae, Thripidae and Cecidomyiidae, and the main natural enemies were Aphidiidae, Trichogrammatidae, Mymaridae, Scelionidae and Chrysopidae.【Conclusion】 The insect community diversity index, evenness index and richness index of jujube orchard in Hami Xinjiang are quite high, which shows a consistent trend, indicating that the insect community there has high stability.
