Study on the trapping effects and field application of different sex attractants against Ostrinia furnacalis

Ostrinia furnacalis(Guenée) is one of the most destructive corn pests. In order to explore biological control method against O. furnacalis, a comparative study was conducted on the efficiency of three different lures(lure A,lure B and lure C), two types of traps(water trap and triangular trap), and different hanging height of traps(1.0, 1.5, 1.8 and 2.0 m)on capture of O.furnacalis in Guanzhong irrigation area. The results indicated that lure A from Pherobio Technology and lure B from Institute of Zoology, Chinese Academy of Sciences both showed high attractive activity to O. furnacalis males,and the activity of lure B was higher. The catches of two trap types differed significantly, and the trapping effects of the triangular trap hanging at 2.0 m height was better than that at 1.5 m height. In conclusion, lure B is more suitable for foreacasting and biological control of O. furnacalis in Guanzhong irrigation area, and triangular trap and hanging height from 1.8 m to 2.0 m is recommended in the field application.
