Abstract: | in this paper the distribution,generation,damage and control of two borers (Asia maize borer,Ostrinia furnacalis.Yelllow sugarcane borer,Chilotraea in fuscatella),Were mainly approached from different ecological range and drawn on entomological information and violet light.Studies shows that there were 5 ecological distribution ranges in Shanxi province.First is no generation range in high frigid mountain with an elevation of 1500 metres,which's frostfree period is less than.100 days.Second is one generation range in lower 1400 metres above sealevel,which's frost-free period 100 days or so.Third is one to two and two generation range,thirty-seven to thirty-nine degres north latitude,which's frost-free period 150 days.Fourth is thirty-seven degrees north latitude beyond south,two to three generations range.Fifth is three generations range,thirty-five degrees north latitude beyond south.Among the most of ranges, damage factor is light.Up to 1300 metres above sea level mountains,C infuscatella was damaged seriously,whereas O.furnacalis in plain.The chemical control are mainly measure and agricultural and biological control are complementaried. |
