摘　　要：薄壳山核桃为胡桃科山核桃属落叶乔木,是重要的油料干果树种,具有较高的经济价值。但是,随着种植规模的不断扩大,病虫害问题日益凸显。本研究在滁州市来安县和南谯区两个地点进行了桃蛀螟迷向试验,旨在探究一种高效、对环境友好的桃蛀螟防治方法。结果表明,迷向区(悬挂迷向剂)桃蛀螟成虫迷向率可达92.9%~100.0%,迷向效果明显。在采收期蛀果率调查中,两个地点迷向区的蛀果率均低于对照区。其中,滁州市林业科学研究所龙亭口基地迷向区的蛀果率仅为15.3%。说明悬挂迷向剂可作为薄壳山核桃栽培中桃蛀螟防治的一种手段。Pecan is a deciduous tree belonging to Carya genus of Juglandaceae family.It is an important oil and dry fruit tree species and has high economic value.But with the continuous expansion of planting scale,the problem of pests and diseases is becoming increasingly prominent.This study conducted a experiment to evaluate the effect of mating disruption in Lai′an County and Nanqiao District of Chuzhou City,aiming to explore an effective and environmentally friendly method for preventing and controlling Conogethes punctiferalis.The results showed that the mating disruption rate of adult Conogethes punctiferalis could reach 92.9%-100.0%in the mating disruption-treated area(hanging mating disruption),and the mating disruption effect was significant.In the survey of fruit-boring rate during the harvest period,the fruit-boring rates in the mating disruption-treated areas of both locations were lower than those in the control areas.Among them,at Longtingkou Base of Chuzhou Institute of Forestry,the fruit-boring rate in the mating disruption-treated area was only 15.3%.It indicates that hanging mating disruption can serve as an effective approach to prevent and control Conogethes punctiferalis in pecan cultivation.
