The trapping efficacy of plant-derived attractant on mirid bugs under field conditions
In this study,we assessed the trapping efficacy of plant-derived attractant on mirid bug adults under field conditions.The results showed that the attractant,in which the mass ratio of butyl acrylate and butyl propionate was 3∶ 1,greatly attracted the adults,and the trapped numbers were significantly higher than those in control group.Using this attractant,the average numbers of mirid bugs on each trap were 3.9 times of those in control group in alfalfa fields in 2015,and were 55.3,39.0 and 15.6 times of the controls in mungbean in Xinxiang,Henan and Langfang,Hebei,and cotton fields in Langfang,Hebei in 2016,respectively,and all were significantly higher than the corresponding controls.And that four common species of mirid bugs,Apolygus lucorum,Adelphocoris suturalis,A.fasciaticollis and Adelphocoris lineolatus,have been trapped during the trial period.The trapped numbers of dominant species,A.lucorum and A.lineolatus in alfalfa,and A.lucorum in mungbean and cotton,were also significantly higher than the control groups.It indicates that the attractant effectively traps mirid bugs,and can be used in the monitoring and management of this pest group.
