Abstract

Seven vegetables were planted in green houses to compare their yields and damages by insect pests based on three treatments, green music (GM), ultra sonic (US) and control. The vegetable yields of GM treatment were increased by an average of 17.81% than that of control for two years. There was a remarkable statistic difference in the yield between GM and respective controls such as radish, young radish, cucumber, spinach and Brassica oleracea var. acephala. There was no notable yield difference between US and controls for the semen vegetables within two years. The population densities of the insect pests in GM and US treatments were lower than controls. Only a few insect pests of some vegetables in GM and US treatments injured more seriously than in control.
