摘　　要：稻水象甲是水稻上一种检疫性害虫,黑龙江省东宁县稻水象甲的发生已有多年,为了进一步探明东宁县稻水象甲成虫的越冬分布情况,分别选取两处调查地点,对其稻田、田埂、沟渠、邻近山坡或林带等生境采用随机取样的方法进行了稻水象甲越冬成虫调查。研究表明,稻田边林带、山坡是稻水象甲成虫越冬的主要生境,其次是沟渠,田埂及稻田间无分布;土质疏松的土层,并且0~5 cm土层中相对湿度在10%~30%适宜稻水象甲成虫越冬。Lissorhoptrus orgzophilus was a quarantine pest on rice.Lissorhoptrus orgzophilus had occurred in Dongning county,Heilongjiang province for many years.In order to further explore the overwintering distribution of Lissorhoptrus orgzophilus adults in Dongning county,two investigation sites were selected to investigate the overwintering adults of rice water weevil in rice fields,ridges,ditches,adjacent hillsides or forest belts by random sampling.The results showed that the main overwintering habitats of Lissorhoptrus orgzophilus adults were the edge forest and hillside of rice field,followed by ditches,and there was no distribution between ridges and rice fields.The soil layer was loose,and the relative humidity in 0~5 cm soil layer was 10%~30%,which was suitable for the overwintering of Lissorhoptrus orgzophilus adults.
