安徽宿州地区蛴螬时空发生特点

摘要

为了解安徽宿州地区农田蛴螬群落的时空发生特点,于2011年8月和10月,以及2012年3月,调查了种植在砂土、砂壤土和黏土3种不同土壤类型上的农田蛴螬群落.结果表明,宿州地区蛴螬群落共有3科14种,优势种为暗黑齿爪鳃金龟(Holotrichia parallela Motschulsky)和小阔胫玛绒金龟[Maladera ovatula (Fairmaire)].蛴螬发生量和种类结构在不同土质与时间下差异显著,其中砂壤土蛴螬数量与种类数均较高,8月为为害高峰期,虫量与种类数最多.研究结果可为安徽宿州地区蛴螬的科学防控提供依据.%In order to explore the characteristics of spatial and temporal occurrence of grubs in the farmland in sand soil,sandy loam and clay in Suzhou,Anhui Province,a field survey was conducted in August 2011,October 2011 and March 2012,respectively.The results showed that the grub community was composed of 14 species in 3 families,and the dominant species were Holotrichia parallela Motschulsky and Maladera ovatula (Fairmaire).The abundance and species richness of grubs showed significant differences among different soil types and periods,with sandy loam being of highest abundance and richness,and the peak occurrence in August.Our results play apotential role in the scientific prevention and control of grubs in Suzhou,Anhui.
