摘　　要：连续 7a调查研究结果表明 :小麦辣椒间作套种的椒田辣椒苗期蚜虫、小叶病发生为害得到了有效控制 ;辣椒疫病、盲蝽、蟋蟀发生为害显著减轻 ,二代棉铃虫卵量减少 69.5 % ,幼虫量减少 3 7.2 % ,为害轻于单作辣椒。小地老虎、粘虫、斑须蝽、四代棉铃虫发生数量增大 ,为害重于单作辣椒田 ;辣椒炭疽病 ,日灼病发生为害程度明显加重。主要生态因素是麦套椒田小气候的改变 。The Effects of pepper wheat interplanting on pepper main diseases and pests was investigated and researched in 7 years. The results showed that aphids at pepper seedling stage and virus diseases had been efficient controlled in the pepper wheat interplanted field. Damages of peper phytophthora peslis. Plant bugs and crickets were decreased evidently. Ova quantity of 2nd generation cotton bollworm and Larra quantity had been reduced by 69.5% and 37.2% respectively. Quantities of black cutworm, oriental armyworm, spotbreard bug and 4 generation cotton bollworm had been increased.
