摘　　要：为了明确梨小食心虫在河北保定桃园的发生情况和4种性诱捕器的田间诱捕效果,对桃园梨小食心虫进行田间性诱捕试验,结果表明:水盆式诱捕器效果最好,一共诱捕到1 293头;其次为桶型诱捕器,一共诱捕到949头;最后为蓝色粘虫板和自制水瓶诱捕器,分别诱捕到489头和153头;在保定满城地区,梨小食心虫2014年出现3个危害高峰,分别是6月下旬、7月中下旬、8月下旬;建议推广使用水盆和桶型诱捕器并在高峰期进行药剂防控。In order to identify the occurrence and the sex pheromone trapping effects of Grapholitha molesta Busck,four kinds of trappers were tested in a peach orchard in Baoding,Hebei Province.The result showed that the basin trapper had the best trapping effect,a total of 1 293 insects were trapped,which was much better than anyone of the other bucket trappers,and the blue sticky trapper and self-made bottle trapper trapped 489 and 153insects respectively.Three harmful peaks of Grapholitha molesta Busck occurred in 2014,respectively in the first ten days of June,the mid to late July and the last ten days of August.Therefore,it is suggested that the basin and bucket trappers are supposed to be the best to be spread and simultaneously chemical control of Grapholitha molesta Busck should be conducted during the peak time.
