Effect of Vine Training on the Yield and the Flower-visiting Insect of Scarlet Runner Bean (Phaseolus coccineus L.)

Abstract

We examined the effect of vine training on the yield and the flower-visiting insect of scarlet runner bean. The insect survey involved the control plot (inside and outside the tunnel) and the vine plot (inside the tunnel). The yield survey involved the control and training plots. As a result, the number of flower-visiting insects and yield were higher outside compared with inside the tunnel. Inside the tunnel, the yield of the control plot showed higher than that of the training plot, and the number of flower-visiting insects showed no difference at control between the plots.
