| 摘 要： | 调查了作物之间的间种对黄曲条跳甲种群数量的影响。结果表明:白菜Brassicachinensis与葱Alliumfistulosum、菜心B.parachinesis与茄子Solanummelongena间作,能显著地减轻黄曲条跳甲对白菜、菜心的为害,间作田上的黄曲条跳甲成虫的发生数量与单种田相比减少明显。在白菜地上间作上芥菜B.juncea,白菜上成虫数量逐渐减少,芥菜上的虫量逐渐增加;在芥兰B.alboglabra地上间作萝卜Raphanussativus后,黄曲条跳甲成虫大都转移到萝卜为害,萝卜上的跳甲成虫数量高出芥兰的十倍甚至十几倍,使间作田上芥兰的黄曲条跳甲种群数量明显少于芥兰单种田,所设置的4种间作相隔距离(2m、4m、8m、15m)之间差异不显著,说明每隔约15m间种一行萝卜就能起到很好的诱集跳甲成虫效果。 |

| Abstract: | Systematic investigation was carried out on the effect of intercrop on the densities of the striped flea beetles (SFB), Phyllotreta striolata (F.). The results indicated that Brassica chinensis intercrop Allium fistulosum, B. paradimesis intercrop Solanum melongena, significantly reduced the damage of the SFB (T-test) and the result from the experiments of the intercrop the preference host-plant with non-preference host-plants of SFB showed that these cultivative methods could reduced the injury by this pest. The planting practical of Chinese kale cultivated at an interval of 2,4,8,15m respectively followed by radish could decrease numbers of SFB population. |
