摘　　要：榆跳象是榆树上的重要食叶害虫之一,近年来在新疆发生严重。为了掌握榆跳象在昌吉州的发生情况,本文利用网室监测榆跳象越冬成虫出蛰和越夏成虫羽化进度,并对其趋光性进行测定,同时开展化学防治。结果表明:在呼图壁县和昌吉市,榆跳象越冬成虫出蛰时间基本处于3月下旬至4月上旬,成虫出蛰持续9~15 d;越夏成虫羽化时间为5月上旬至5月底,成虫羽化持续20 d左右;混用1%苦参碱和20%吡虫啉可以有效控制榆跳象的种群数量,保证榆树叶片正常生长;榆跳象对绿色、蓝色、黄色、白色和红色灯光的趋性没有显著差异,不建议采用灯光诱杀的方法防治。Rhynchaenus aliniis one of the important leaf-eating pests in elm.In recent years,it has occurred seriously in Xinjiang.In order to master the occurrence of Rhynchaenus alini in Changji Prefecture,this paper monitored the emergence of overwintering adults and the eclosion of oversummering adults by using the net room,and measured the phototaxis of Rhynchaenus alini,and carried out chemical control.The results showed that in Hutubi County and Changji City,the overwintering adults emergence time of Rhynchaenus alini was basically from late March to early April,and the adult emergence lasted for 9-15 d;the eclosion time of oversummering adults was from early May to the end of May,and the eclosion lasted for about 20 d.The mixed application of 1% matrine and 20% imidacloprid could effectively control the population of Rhynchaenus alini and ensure the normal growth of elm leaves.There was no significant difference in the phototaxis of Rhynchaenus alini to green,blue,yellow,white and red lights,so it was not recommended to use light trapping for prevention and control Rhynchaenus alini.
