It was the first trial to employ the newly equipped migration data acquisition and analysis system for the scanning entomological radar and, a twin light - trap developed in china for, systematic long - term observations of migration of the beet armyworm spodoptera exigua, beet webworm loxostege sticticalis and cotton bollworm helicoverpa armigera in northern china the study provided direct evidence for the migration of 5 ". exigua in china, many parameters of migratory behaviour of the three species of insects, a better understanding of the relationship between migratory behaviour and wind or temperature field. the results enriched the theory of migration and provided new scientific knowledge for pest management in china
本研究初步闡明了我國華北地區空中昆蟲群落結構，首次使用我國自行研製的掃描昆蟲雷達的數字化數據採集及分析系統，及價廉、高效的姊妹燈誘蟲法對華北地區甜菜夜蛾spodopteraexigua 、草地
螟loxostegesticticalis和棉鈴蟲helicoverpaarmigera的遷飛進行了長期系統地觀測，得到了甜菜夜蛾在我國北方遷飛的直接證據，三種
害蟲遷飛行為的若干參數，認識了昆蟲遷飛行為與風溫場的關系，豐富了昆蟲遷飛理論，為我國
害蟲的治理提供了科學依據。

害特點及嚴重發生原因剖析
The diversity index showed that neca > pca > cka, and so did the evenness index. the dominant concentration index showed that cka > pca > neck. so the stability of the arthropod community in neca is best and that in cka is worst in the three areas
同時，常規對照棉田中時有發現的紅鈴蟲（ peetinophoragossypxellasaunders ） 、玉米
螟（ ostriniafurnaeali : （ euenee ） ） ，在轉bt墓因棉田中沒有發生，表明轉bt基因棉對棉田中大多數鱗翅目
害蟲具有良好的抗性
The occurance of powdery mildew, rust, maruca testulalis geye of cowpea were studied after cowpea had been handled by different kinds of foliar fertilization, and the indexes such as ppo and yields, were measured. the results showd that, using fertilizers reasonably could raise resistance of plants to pest, increase yields of crops and guarantee quality of products
摘要研究了經不同葉面肥處理后，豇豆白粉病、銹病、豆野
螟的發生情況，測定了多酚氧化酶（ ppo ） 、產量指標，結果表明，合理施肥能夠提高植物對有
害生物的抗性，增加產量，保證品質。
