摘　　要：为研究韭菜迟眼蕈蚊在北柴胡种植地中的空间格局,2022年5~6月对韭菜迟眼蕈蚊成、幼虫在略阳北柴胡种植地中的空间分布情况进行调查,采用频次比较法对调查结果进行多种分布型的拟合计算。结果表明在北柴胡种植地中,韭菜迟眼蕈蚊幼、成虫的空间格局均为聚集型分布,符合负二项分布。韭菜迟眼蕈蚊成虫在北柴胡种植地中主要集中在植株顶部上方飞行,植株顶部上方0至30.00 cm高度内的成虫占比达到71.51%,其中在植株顶部上方约15.00 cm处飞行的成虫最多,粘虫板粘附成虫数量达到10.6头/板。To investigate the characteristics of the spatial pattern of Bradysia odoriphaga in Bupleurum chinense planting regions,a survey was conducted on the spatial distribution of Bradysia odoriphaga adults and larvaeon Bupleurum chinense in Lueyang from May to June in 2022.The spatial distribution pattern of Bradysia odoriphaga was determined using frequency distribution method.The results showed that both the larvae and adults of Bradysia odoriphaga on Bupleurum chinense exhibited an aggregated distribution,following a negative binomial distribution.In the Bupleurum chinense planting fields,the adults of Bradysia odoriphaga were mainly observed above the top of the plant,with 71.51%of adults found within the height range of 0 to 30.00 cm above the plant top.Among them,the highest concentration of adults was observed at approximately 15.00 cm above the top of the plant,with a corresponding count of 10.6 adults adhering to the armyworm plate.
