Structural Pest Control Applicator Practice Exam

Which type of effects occur away from the point of pesticide contact?

1. Local effects

2. Systemic effects

3. Both local and systemic effects

4. Chronic effects

The correct answer is: Systemic effects

The correct answer is systemic effects because these effects manifest in parts of the organism that are not directly contacted by the pesticide. When a pesticide has systemic properties, it is absorbed and distributed throughout the entire organism, impacting various physiological processes in tissues or organs that are remote from the entry point. This characteristic allows systemic pesticides to provide longer-lasting protection or control by affecting pests that may not be immediately adjacent to the application site. In contrast, local effects are confined to the area where the pesticide was applied, meaning they do not occur far from the point of contact. Chronic effects refer to long-term health impacts resulting from prolonged exposure to a pesticide, but they do not specifically relate to the immediate effects arising from pesticide application at a distance from where it was applied. Both local and chronic effects are thus distinct from systemic effects, which emphasizes the importance of understanding the nature of pesticide action in pest control scenarios.
