摘要
铜绿丽金龟成虫羽化后出土是新一轮为害的开始,确定影响铜绿丽金龟成虫出土的环境因子,是预测成虫出土时期和出土虫量的前提条件。通过分析温度和降水两个因子对沙地榛园铜绿金龟成虫出土量的影响,结果表明:铜绿丽金龟成虫逐日出土量与土壤温度呈线性正相关,并且温度持续升高能缩短成虫发育时间;同比沙地榛园2017年、2018年降水情况,分析得出降水因子对铜绿丽金龟的成虫出土量有促进作用,特别在6月份,降水因子对虫口数量的影响较大。该研究对铜绿丽金龟的综合治理具有重要意义。
In The emergence of adult Anomala Corpulenta is the beginning of a new round of damage.Determing the environmental factors that affect the emergence of adult of A.Corpulenta is the prerequisite for predicting the emergency period and adult population.The influence of temperature and rainfall on the adult population of A.Corpulenta in sandy hazel orchard were analyzed.The results indicated that there was a positive linear correlation between the daily adult amount of A.Corpulenta and soil temperature,and the continuous increase of temperature could shorten the development time of the adults.Comparing the precipitation situations in 2017 and in 2018 of hazel orchard in sandy land,it was concluded that precipitation had a promoting effect on the adult amount of A.Corpulenta,especially precipitation in June had a great influence on adult population.This study was of great significance to the comprehensive management of A.Corpulenta.
