摘要

本研究利用不同害蟲偏好之陷阱作物與主要作物同時耕作，針對尼泊爾半翅目害蟲進行蟲害管理。選用六種綠豆品種[VC6173A, VC6153B-20G, VC3960A-88, Kalyan, Pratikchha, and Saptari local (as the control)]與Saptari原生種比較。結果顯示所記錄到半翅目害蟲之數量在不同品種間具有顯著性差異，以VC6173A（3.25 bugs/plant）害蟲數量最多且其產量最少。以三種不同陷阱作物在田間進行耕作規劃，發現以Pratikchha作為主要作物而以VC6173A作為陷阱作物之方式，與其他兩種方式具有顯著性差異。結果顯示VC6173A為最適合在尼泊爾綠豆種植之陷阱作物。

This study was conducted on hemipteran bugs on mungbean in Nepal. A trap crop of a variety preferred by the bugs was planted along with the main crop. The tests were performed using a selection of six of the most preferred mungbean varieties [VC6173A, VC6153B-20G, VC3960A-88, Kalyan, Pratikchha, and Saptari local (as the control)] relative to the Saptari local variety. Significant differences were recorded in the number of bugs among the six varieties, with a maximum number of bugs in VC6173A (3.25 bugs/plant) showing the lowest yield. Three different trap crop designs were employed in the field. There was a significant difference between variety Pratikchha as the main crop and variety VC6173A used as the trap crop in two of the designs. The data suggested that VC6173A is a probable trap crop and that those two designs can be employed in the field in Nepal.
