What is the initial step in the flotation method for pest detection?

The initial step in the flotation method for pest detection involves cutting the bottom off a coffee can. This preparation is essential because the can serves as a tool to collect and contain a sample from the soil. By removing the bottom, the can can be inserted into the soil to extract earth and any pests that may be present. This step is crucial in ensuring that the sample is representative and can be effectively analyzed for pest detection.

Pouring water into the can, stirring the soil, and counting insects occur after the can has been prepared and inserted into the soil. These actions are part of the subsequent steps in the flotation process, which involve separating the pests from the soil or debris, facilitating the identification of pests for management decisions.
