摘要
对广东湛江地区甘蔗田节肢动物群落进行了系统调查.结果表明,广东湛江地区甘蔗田节肢动物群落物种十分丰富,共计2纲15目62科117种.其中害虫亚群落分属于8目28科54种,天敌亚群落包括9目23科43种,中性昆虫亚群落包括4目11科20种.中性昆虫亚群落的多样性指数和均匀性指数均高于总群落,优势集中性指数低于总群落,表明中性昆虫个体数量在物种间的分布较为均匀.而害虫亚群落和天敌亚群落则相反,其个体数量在各自的物种间分布不均匀,优势种的个体数量占整个亚群落个体数量的比例较高.
A systematical investigation on arthropod community was carried out in sugarcane field in Zhanjiang,Guangdong Province.The results showed that the arthropod species were abundant in sugarcane field.There were totally 117 species of arthropod,which belong to 2 classes,15 orders and 62 families.Among them,fifty-four species of insect pests belonging to 8 orders and 28 families,43 species of natural enemies belonging to 9 orders and 23 families,and 20 species of neutral insects belonging to 4 orders and 11 families were identified.It was found that sub-community of the neutral insects had the highest indices of diversity and evenness but the lowest index of dominance,and indicated that the individuals of neutral insect were evenly distributed in almost species.However,the pest sub-community and natural enemy sub-community on the contrary,their individuals were unevenly distributed in various species.
