摘要
近30年来同安区水稻三化螟发生呈缓慢下降态势,越冬虫源减少,盛发期缩短,灯下诱蛾量下降。该文分析了1970年以前、1971～1982年和1983～2007年三化螟在同安区的发生动态,并对其相关因子进行分析。
Occurrence tendency of yellow rice stem borer decreased slowly in Tong＇ an District in recently 30 years, with rare overwintering pest source, shortening peak incidence period and decreasing insect population under the trap lamps. The occurrence dynamics of yellow rice stem borer before 1970 years ago, during 1971 - 1982, and after 1983 - 2007 were analyzed. Meanwhile, its correlation factors were briefly analyzed in this paper.
