摘　　要：为明确东方绢金龟为害金银花的特点和规律,对其越冬情况进行了田间系统调查。结果表明：东方绢金龟在金银花田主要以老熟幼虫在土壤中筑土室越冬,随着冬季环境温度下降,该虫逐渐向土壤深层移动,平均分布深度由距地表13.4cm潜至16.2cm;深度为10~20cm土层的个体数量最多,30~40cm土层个体分布最少;植株不同方位虫口密度无明显差异。研究结果可为金银花田东方绢金龟的防治提供理论依据。A field investigation was carried out to verify the overwintering of Serica orientalis Motschulsky in honeysuckle（Lonicera japonica Thunb.）field.The results showed that the pest overwintered with mature larva by building underground nest in the soil of honeysuckle field.With the ambient temperature dropped in winter the population gradually moved into the deeper soil,from13.4 cm to16.2 cm below ground.Most individuals located at soil layer of 10 cm to20 cm in depth,and the least at 30 cm to40 cm soil layer.There was no significant difference in population density with different plant directions.The results provides theoretical basis for the pest control in honeysuckle field.
