摘　　要：为了确定色板颜色、悬挂高度和种群动态对‘白旗韭黄’主要害虫诱集和天敌规避的效果。本研究以黄、蓝、黑3种色板分别悬挂0、20、40 cm于田间对主要害虫和天敌进行持续5个月的诱集。结果表明:色板共诱集昆虫纲10目38科67种,腹足纲1目2科2种,蜱螨亚纲1目1科1种。色板主要诱集双翅目、半翅目和鞘翅目昆虫,诱集数量为双翅目>半翅目>鞘翅目。黄板对韭菜迟眼蕈蚊和台湾韭蚜的引诱效果最佳,黑板对瓢甲科天敌规避效果最好。悬挂离地40 cm的黄板对韭菜迟眼蕈蚊和台湾韭蚜的诱集效果最好,蓝板悬挂20 cm时对瓢甲科的规避效果最差。韭菜迟眼蕈蚊和台湾韭蚜在调查期的7月中旬达到诱集高峰期,韭菜迟眼蕈蚊从10月中旬后开始呈上升趋势,瓢甲科在8月中旬至11月底种群动态呈两个高峰期,分别为8月中旬至9月上旬和10月中旬至11月下旬。因此,从7月中旬至8月中旬以及10月底开始悬挂离地40 cm黄板对‘白旗韭黄’害虫防治效果、天敌规避效果最好。To evaluate the effects of sticky trap color,hanging height and population dynamics on attraction major pests and avoidance natural enemies in Baiqi Allium tuberosum,yellow,blue,and black sticky traps were tested at heights of 0,20,and 40 cm above ground in the field to trap major pests and natural enemies for five months.The results showed that the sticky traps attracted a total of 67 Insecta species from 10 orders and 38 families,2 Gastropoda species from 1 order and 2 families,and 1 Acari species from 1 order and 1 family.The sticky traps primarily attracted insects from Diptera,Hemiptera,and Coleoptera,with the attraction effects ranked as Diptera>Hemiptera>Coleoptera.Yellow boards were most effective in attracting Bradysia odoriphaga and Neotoxoptera formosana,while black boards were best at avoidance natural enemies from the family Coccinellidae.The optimal attraction for B.odoriphaga and N.formosana occurred with yellow boards placed 40 cm above ground,while blue boards at 20 cm had the weakest avoidance effect on Coccinellidae.Population dynamics indicated that B.odoriphaga and N.formosana peaked in mid-July during the survey period,with B.odoriphaga increasing again from mid-October onwards.Coccinellidae populations showed two peaks:mid-August to early September and mid-October to late November.Therefore,suspending yellow boards 40 cm above ground from mid-July to mid-August and starting again in late October is recommended for optimal pest control and natural enemy conservation in Baiqi A.tuberosum.
