| Abstract: | Rice water weevil is an important pest in rice fields. Experiments have been carried out in rice seeding boxes for two years (1996~ 1997). The effectiveness of different pests intensities on rice yields was found out, which suggested that 30 rice water weevils per SM (square metre) was the control index. |
