英文摘要: |
The conventional simple sampling method for egg scouting was improved as a nested and graded one in this study. Application results demonstrated that this method raised the efficiency and accuracy of egg scouting and reduced labor and time for field investigations. Through graded egg scouting, the optimum treatment time has been predicted and chemical control supervised, which led to obvious improvement in control efficacy. |
