The advantage of using a pest survey statistic device is to make investigators lose the old-fashioned way of writing pen records, and it is also more convenient for data recording and processing. For example, a pest survey statistic device can be used to count pest types, outbreak time, etc. And upload this data to the computer for backup storage, convenient for later data viewing and analysis. However, there is a precondition that the collection of pest data must be representative. Therefore, the selection of sampling points is particularly critical when using pest survey statistics.
At present, the most common sampling methods for pest surveys are: single-diagonal, double-diagonal, or five-point, checkerboard, parallel-line, and “Zâ€-shaped sampling. Why are there so many different pest survey sampling methods? The main reason is that different types of pests are suitable for different sampling methods. For example, the “Z†shaped sampling is applicable to pests with more distributions at the field side; the dual diagonal, checkerboard, and parallel lines are suitable for Non-uniform distribution of pests in the field; and single-diagonal, five-point applies to pests distributed in the field.
