摘要
通过对 4种油菜品种和 4种栽培方式油菜田害虫及天敌的种群数量调查 ,结果表明 :油菜生长中后期害虫优势种群为桃蚜和油菜潜叶蝇 ;油菜田天敌不足以有效控制其害虫的为害 ;油菜品种和栽培方式间害虫种群数量存在显著差异。
Investigation was given to the population quantity of the pest and natural enemy in four rape varieties and four culture patterns. The variance analysis and significant different test showed that:①Phytomyza horticola Gowwreau and Myzus persicae Suler were the dominant species in rape field during middle-later period.②The pest was effectively controlled with natural enemies because of its low quantity. ③Significant difference can be found in pest's population quantity among different rape varieties and cultivate patterns.
