Which of the following is not a common method of insect presentation?

Plastic resin is not a common method of insect presentation in pest control practices. The focus in insect presentation typically revolves around formulations that effectively deliver active ingredients to target insects. Common methods include liquid applications, which allow for broad coverage in various environments; solid formulations, which can be used in baits or granules; and aerosol, which provides a fine mist that allows for quick and even distribution of insecticides in targeted areas.

In contrast, plastic resin does not typically serve as a delivery mechanism for insecticides. Instead, resins might be used in the manufacturing of containers or tools that hold insecticides but would not directly relate to how the pesticides are presented or delivered to insects. Understanding these distinctions helps in recognizing effective pest control methods and their proper applications.
