Mungbean is an important crop in Nepal. Heteropteran bugs, Nezara virudula, Dolycoris baccurum, and Melanacanthus scutellaris are significantly influencing qualitative and quantitative loss in soybean and mungbean. Though pesticide application is common practice for management of these bugs, pesticide avoidance by the bugs stalls proper management. As an alternative, trap cropping with variety mostly preferred by the bugs as trap crops along with the main crop is considered. Selection of most preferred mungbean variety was performed with six (VC 6173 A; VC 6153 B-20G; VC 3960 A-88; Kalyan; Pratikchha; Saptari local) relative to Saptari local variety. Significant difference was recorded in number of bugs occurrence among the six varieties with maximum number of bugs in VC 6173 (3 bugs/plant) which showed lowest yield. For application, three different trap crop designs were employed in the field. There was significant difference between the main crop i.e. variety Pratiksha and the variety VC6173A used as trap crop in two designs. In conclusion VC6173A is a probable trap crop and the two designs can be employed in the field.
