1. 10

2. 1

3. 5

4. 25

The correct answer is: 1

The concept that only a small fraction of insects are considered pests is rooted in the extensive diversity of the insect population. Insects make up the largest group of organisms on Earth, with millions of species identified and likely many more yet to be discovered. Among these species, only about 1% are regarded as pests that cause harm to human activities, property, or health. This percentage highlights the balance of ecosystems, where most insects either play beneficial roles in processes such as pollination, decomposition, and as part of the food chain, rather than being harmful. The vast majority of insects contribute positively to the environment, while only a tiny segment is problematic. Understanding this context is essential for pest control applicators, as it frames the approach towards managing and controlling pests, against the backdrop of conserving beneficial insect populations.
