分别于2003~2004年11月至翌年4月,对昆明地区蚕豆小麦不同行比间作模式下南美斑潜蝇的发生危害规律进行了系统的调查研究。结果表明,蚕豆和小麦行比为1∶4,1∶6种植模式对南美斑潜蝇的控制作用明显高于1∶2种植模式,在1∶4,1∶6种植模式下,南美斑潜蝇的虫情指数最低,分别为22.02%,18.04%;相对防治效果最高,分别达到34.26%,37.63%;成虫虫口减退率最高,分别为36.74%,59.78%;经方差分析,处理1∶4,1∶6为控制南美斑潜蝇最佳种植模式。 From 2003 to November 2004 to April of the following year, we conducted a systematic investigation on the occurrence and damage of the South American leaf miner, Phala The results showed that the control effect of faba bean and wheat on the ratio of 1: 4 and 1: 6 was significantly higher than that on the 1: 2 plantation. Under the 1: 4 and 1: 6 planting modes, The insects index of flies was the lowest (22.02% and 18.04% respectively), while the relative control effect was the highest (34.26% and 37.63% respectively). The adult worms had the highest reduction rate of 36.74% and 59.78%, respectively. , 1:6 to control the best planting pattern of Liriomyza sativae.
