What is a requirement when there is resistance in mosquito populations to some control materials?

When mosquito populations exhibit resistance to certain control materials, there is a critical need to follow specific testing protocols. This requirement is essential to accurately identify the resistance and determine the best course of action for effective mosquito management. Testing helps in assessing the extent of the resistance and in devising strategies that may include rotating control materials or integrating various control measures to mitigate the impact of resistant mosquito populations.

Employing these testing protocols ensures that pest management practices remain effective and can adapt to the challenges posed by resistance. By understanding the nature and mechanics of the resistance, professionals can make informed decisions on pesticide application, reducing the likelihood of continuing to use ineffective materials, which could exacerbate the resistance problem.

The option that resistance has never been detected in Michigan does not provide a realistic strategy for dealing with the very real and ongoing issue of resistance management. Similarly, suggesting that no control efforts be made for a period of two years or that the issue must be addressed solely through environmental changes does not align with the proactive and scientifically grounded approach required for effective mosquito control.
