为选择适用于黄河流域和长江流域棉区盲蝽的诱测灯具,准确掌握棉田盲蝽种群发生动态,2011-2014年选择频振12号灯、16号灯、18号灯、绿光灯和黑光灯,以常用的黑光灯为对照,在两大棉区的10个省12个站点进行了诱测试验。结果显示,在以绿盲蝽为优势种的黄河流域,16号灯和12号灯诱虫量分别是黑光灯诱虫量的4.5倍、3.6倍,18号灯和绿光灯分别是黑光灯的1.7倍和1.3倍;在以中黑盲蝽为优势种的长江流域,绿光灯诱虫量是黑光灯的3.9倍,12号灯、16号灯、18号灯诱虫量分别是黑光灯的1.3倍、1.5倍和1.9倍。各地盲蝽优势种和虫量动态较好地反映了两大棉区盲蝽田间种群结构。在黄河流域棉区,可诱到绿盲蝽、中黑盲蝽、三点盲蝽、苜蓿盲蝽,以绿盲蝽和中黑盲蝽为优势种,局部地区苜蓿盲蝽和三点盲蝽种群比率较高;在长江流域棉区,可诱到中黑盲蝽、绿盲蝽、三点盲蝽、牧草盲蝽,以中黑盲蝽为优势种,北部地区绿盲蝽种群比率较高。因此,黄河流域棉区推荐优先使用频振16号灯和12号灯,其次是频振18号灯,不推荐使用黑光灯;长江流域优先使用绿光灯,其次是频振18号灯、16号灯和12号灯,黑光灯亦可使用。
In order to select the suitable inducing luminaries for the Lygus australis in the Yellow River valley and the Yangtze River valley and accurately grasp the population dynamics of Apodemus agaricus in the cotton fields, the vibration frequency of 12th, 16th, 18th, green and Black light, the commonly used black light as a control, in two cotton areas in 10 provinces in 12 sites induction test. The results showed that in the Yellow River Basin where the dominant species of Apolygus lucorum were dominant, the parasitization rates of lamp 16 and lamp 12 were 4.5 times and 3.6 times that of black light, respectively. The 18 and the green light were black light 1.7 times and 1.3 times; in the Yangtze River valley dominated by black bugs, green light trap insects 3.9 times the amount of black light, 12 lights, 16 lights, 18 light trap were black light Light 1.3 times, 1.5 times and 1.9 times. The dynamics of dominant species and insects in Lygus were well reflected in the field population structure of two planthoppers. In the cotton area of the Yellow River, green bug, Midopian bugs, Apodemus agrarius, Aphanomycotis leucocephala, Apodemus agrarius and Apodemus agrarius were the dominant species. In some areas, In the cotton area of the Yangtze River valley, Apodemus agrarius, Apolygus lucorum, Apodemus agrarianus and Lygus nudibranch can be induced. The dominant species is Apolygus lucorum, and the population of Apolygus lucorum in the northern area is high . Therefore, it is recommended to use the Vibration 16 and 12 lights first in the cotton area of the Yellow River Basin, followed by the Vibration 18 light, and the black light is not recommended; the green light is preferred in the Yangtze valley, followed by the Vibration 18 light and 16 Light and 12 lights, black light can also be used.
