对花椰菜田斜纹夜蛾3代(主害代)卵分布型进行多种抽样技术比较,研究结果表明,该虫在花椰菜田卵分布呈小聚集团(个体群),小聚集团间呈均匀分布。采用随机取样、跳跃式五点取样、对角线五点取样均能较好地反映田间卵量。
The results showed that the eggs distributed in cauliflower field showed small agglomerations (individual groups) and the small agglomerations were evenly distributed . Using random sampling, jumping five-point sampling, diagonal five-point sampling can better reflect the amount of field eggs.
