摘　　要：对甜高粱田内玉米螟进行了调查,并研究了不同药剂对其的防治效果。结果表明,甜高粱玉米螟以在1节内或钻过1节为害为主,且主要为害第6～8节。在成熟期,处理1和处理2的株高、生物产量和锤度均显著高于对照,透孔数显著低于对照;处理2的防治效果最好,增产率达18.77%。在天津甜高粱产区,可在心叶末期,用0.1%氯氟氰菊酯颗粒剂拌10倍细炉渣撒入心叶防治玉米螟。This test invested Ostrinia furnacalis in sweet sorghum fields and studied the effect of different medical treatments.The results showed that Ostrinia furnacalis damaged in one node or drilled the node and the most seriously damaged nodes were from the 6th to 8th.At mature stage,plant height,biomass,and brix of treatment 1 and 2 were significantly higher than CK and thorough-hole number was significantly lower than CK.The control effect of treatment 2 was the best,and increasing rate 18.77%.In sweet sorghum producing area of Tianjin,Ostrinia furnacalis could be controlled by applying 0.1% cyhalothrin particles with 10 time’s thin slag in heart leaves at the late whorl stage.
