本项研究得出了在肯塔基地区进行免耕种植苜蓿对其叶生性昆虫的影响。在免耕条件下,昆虫种群数没有明显的增加。就蚕豆微叶蝉[Empoasca fabae(Harris)]而言,因免耕导致杂草群落增加,其种群数有所降低。免耕条件下,叶面捕食性昆虫数没有明显增多。
This study led to the effects of no-till alfalfa on foliar insects in the Kentucky area. Under no-till conditions, the number of insect populations did not increase significantly. For Empoasca fabae (Harris), the number of herds decreased as a result of increased tillage weeds. No-tillage conditions, the number of predatory insects no significant increase.
