| 摘 要： | 应用离散性指标对豌豆潜叶蝇在采种大白菜田的分布进行了研究,结果表明:幼虫、蛹和种群均为聚集分布.聚集均数(λ)值分析表明:聚集的原因主要是由昆虫行为引起的。豌豆潜叶蝇种群的理论抽样数公式为:N=1681.25/x+0.3075.

| Abstract: | The pea leaf miner P.atricornis in the seed farm of Chinese cabbage was analysed by the indices of dispersin. The study showed that the spitial distribution of the larvae pupae and population all were the clumped distribution. Bliackiths λ value stated the clump was caused by the insect behavior.The formula of the theoretic sampling num- ber was:N=1681.25/x+0.3075 |
