摘　　要：为掌握宁南山区杏园食心虫发生规律,2018年和2020年采用性诱监测方法对彭阳县杏园梨小食心虫、桃小食心虫和李小食心虫成虫种群动态进行了系统监测。结果表明,宁南山区杏园梨小食心虫成虫田间发生期为4月上旬至9月中旬,发生高峰分别为4月底至5月初、5月下旬初和6月中旬末至下旬初,7月上旬后零星发生,无明显峰期。不同坡向虫口数量分布呈现东坡>南坡>西坡,不同坡向的上、中、下坡位虫口数量均以中、下层坡位分布为主。桃小食心虫成虫发生期为5月中旬或下旬至8月下旬或9月初,发生高峰分别为6月上旬或中旬初和7月中旬或下旬;李小食心虫成虫发生期为5月上旬至9月上旬,发生高峰分别为6月上旬、7月上旬和8月上旬。宁南山区对杏园3种食心虫防治可以采取以农业防治为基础,优先采用理化诱杀和生防技术,大发生时加强药剂适期防治的综合防治策略。In order to master the occurrence rule of fruit-borer in apricot orchards in Mountainous Areas of Southern Ningxia the population dynamics of Grapholitha molesta,Carposina sasakii and Grapholitha funebrana adults were systematically monitored with sex pheromone traps in Pengyang County′s apricot orchards in 2018 and 2020.The results showed that Grapholitha molesta adults emerged from early April to mid September,and its occurring peaks in late April and early May,in late May,in middle and late of June,respectively.There was no significant peak after early July.The population in different slopes presented eastern slope>southern slope>western slope,and the population in different slope position were mainly distributed in the middle-lower slope position of different slope.Carposina sasakii adults emerged from middle or last of May to late August or early September,and its occurring peaks in early or middle of June and in middle or last of July,respectively.Grapholitha funebrana adults emerged from early May to early September,and its occurring peaks in early June,in early July and in early August,respectively.In the mountainous areas of Southern Ningxia,the prevention and control of the three kinds of fruit-borer in apricot orchards can be based on agricultural control,giving priority to the use of physical and chemical trapping and biocontrol techniques,and strengthening the timely control of pesticides when major outbreaks occur.
