摘  要:
昆虫对寄主植物种类,特别是对嗜食植物的选择,并不是永恒不变的。随着种植结构的调整、耕作制度的改变、品种的替换,昆虫对寄主的选择往往会发生变化。调查结果表明,在单季稻种植区内混种超甜玉米(第二茬),超甜玉米均成为玉米螟、二化螟和大螟的更高层次的寄主。在离超甜玉米地200 m的范围内玉米螟、二化螟和大螟对超甜玉米表现出强烈的趋向性,防治上将螟虫从目的作物引诱到非目的作物来保护目的作物,以达到防治目的,对其发生动态的预测很有指导意义。

摘  要:
Insects is not immutable on the host plant species,especially the preferable plants of choice.With the adjustment of planting structure,changes in farming systems,replacement of varieties,insects on the choice of host will often change.Survey results showed that the single cropping of rice cultivation in the region of super sweet corn hybrid(second crop),had become super-sweet corn borer,Chilo suppressalis and Sesamia inferens host in a higher level.Away from the super-sweet corn to within 200 meters of the Fan corn borer,Chilo suppressalis and Sesamia inferens showed their strong trend to supersweet corn,and on prevention and treatment,borer from the purpose crop would be tempted to non-purpose crops to protect the crop and reach the prevention and treatment purposes.The study have a very important guiding significance for forecasting borer occurrence dynamic.
