| 利用灯光控制害虫是蔬菜绿色防控的重要手段之一。本文以黄瓜为供试材料，研究蓝光照射对设施黄瓜蚜虫种群数量的影响。结果表明，蓝光照射对设施黄瓜上有翅蚜和无翅蚜均有较强的驱避作用，蓝光照射2 d后，有翅蚜和无翅蚜种群数量分别下降了65.91%和45.26%，校正虫口减退率分别达到了54.22%和52.83%。随着照射时间的延长，蚜虫种群数量持续下降，校正虫口减退率不断上升，照射14 d后，有翅蚜和无翅蚜种群数量分别下降了78.18%和96.40%，校正虫口减退率分别达到了76.67%和96.40%。蓝光照射可以增加黄板对蚜虫的诱集虫量，蓝光照射3 d后，处理区黄板上蚜虫的数量较对照区黄板增加65.08%。研究发现，蓝光照射对黄瓜蚜虫具有直接的驱避作用，同时还可以增加黄板对蚜虫诱集作用。 |

| Using light to control insect is one of the important strategies of vegetable green control. In this paper, the control effects of blue light on aphid on greenhouse cucumber were studied. The results showed that both alate aphid and apterous aphid on greenhouse cucumber were repelled by blue light. After 2 days of blue light irradiation, the populations of alate aphid and alate aphid decreased by 65.91% and 45.26%，and the corrected decline rate reached 54.22% and 52.83%, respectively. With the prolongation of irradiation time, the aphid population declined continuously, and the corrected decline rate of insect population increased continuously. After irradiation for 14 days, the alate and apterous aphid population declined 78.18% and 96.40%, and the corrected decline rate was up to 76.67% and 96.40%, respectively. Blue light irradiation could increase the aphid amount of yellow board. After blue light irradiation for 3 days, the number of aphids on yellowtrap increased to 65.08% compared with that in the control area. Our results suggest that blue light irradiation has direct repellent effect on cucumber aphids, and also enhanced the attractive effect of yellow board to aphids. |
