摘要
为明确冬季管理对盘锦养蟹稻田主要害虫灰飞虱越冬情况的影响,于2019～2022年冬季在辽宁省盘锦市太平镇、唐家镇、坝墙子镇、陆家镇、赵圈河镇和西安镇展开了灰飞虱越冬情况调查.结果表明:灰飞虱能在盘锦地区越冬;养蟹稻田防逃墙及杂草丛是其主要的越冬场所;开展冬季管理的养蟹稻田灰飞虱越冬虫口率明显低于未开展冬季管理的养蟹稻田.表明实施冬季管理能降低盘锦养蟹稻田灰飞虱越冬虫量.
Abstract
In order to clarify the effect of winter management on the overwintering situation of small brown planthopper(SBPH),a survey of the overwintering situation of the small brown planthopper was conducted in Tai Ping,Tang jia,Ba qiangzi,Lu jia,Zhao quanhe and Xi'an towns of Panjin City,Liaoning Province,during the overwintering period of 2019-2022.The results showed that small brown planthopper can overwinter in the Panjin area,and the main overwintering site of small brown planthopper was the weed accumulation and the fence of the rice crab field.The overwintering rate of small brown planthopper in winter managed rice crab fields was significantly lower than that not in winter managed rice crab fields.It showed that winter management of rice fields can effectively affect the overwintering of small brown planthopper.
