桃蚜嗅觉行为反应在辣椒抗蚜筛选中的应用

Application of olfactory behavioral response with resistant to Myzus persicae in the pepper

为了明确桃蚜(Myzus persicae)嗅觉行为反应在辣椒抗蚜材料筛选中的作用,利用昆虫嗅觉行为装置和蚜量比值法,研究了桃蚜对18种辣椒材料的选择行为。昆虫嗅觉行为反应测定结果表明,线椒33对桃蚜具有显著的引诱效果,BZ15016-1、皱皮牛角椒、S23-1-1、超大甜椒2号对桃蚜具有显著的驱避效果。田间调查计算蚜量比值的结果表明,线椒33、薄皮羊角椒、超大甜椒1号和线螺为高感材料,皱皮牛角椒、S23-1-1、超大甜椒2号为高抗辣椒材料。两种方法的研究结果较为一致,为辣椒抗蚜育种材料或辣椒抗蚜品种筛选提供了新的研究思路。

To clarify the role of olfactory behavioral response with resistance to Myzus persicae in the pepper,18 pepper parent materials were researched by using aphid ratio method and the devices of the olfactory behavioral response.According to the study of determination which used the olfactory behavioral response devices,the parent material Xianjiao 33 of the pepper had significant attraction,BZ15016-1,Zhoupiniujiaojiao,S23-1-1 and Chaodatianjiao 2 had significant repellent from the others.According to the field investigation and the calculation of the aphid ratio,the parent materials Xianjiao 33,Baopiyangjiaojiao,Chaodatianjiao 1 and Xianluo of the pepper were also highly susceptible to M.persicae,Zhoupiniujiaojiao,S23-1-1 and Chaodatianjiao 2 were highly resistant to M.persicae.The results showed that both results were high consistently.This study provided a new research approach in aphid-resistant screening of pepper parent materials and pepper varieties.
