| Abstract: | Based on the relationship between population density of Echinocnemus squameus and rice yield loss, combined with rice price, yield level and control costs, the rice yield losses caused by E. squameus were tested, and the economic thresholds of controlling E. squameus were set up. With cumulative insect-day as control index, the optimum control period of E. squameus was determined in Jiangxi Province. |
| Keywords: | Echinocnemus squameus Billberg yield loss economic threshold optimum control period |
