Step 1
Identify ONE appropriate method to estimate how widespread a locust infestation might be.
Answer
One appropriate method to estimate the spread of a locust infestation is the use of aerial surveys. Aerial surveys involve flying over affected areas and visually assessing locust populations and their distribution. This method allows for a broad overview of the infestation and can be conducted quickly over extensive areas.
Step 2
State ONE other valid piece of information that could be collected about locusts, and identify how this information is useful in developing a method for controlling the pest.
Answer
One other valid piece of information is the locust life cycle, particularly the timing of their reproductive phases. Understanding the life cycle allows farmers and pest control managers to target intervention strategies, such as applying pesticides, during critical periods to effectively reduce locust populations before they can mature and spread further.
