What percentage of insect species is considered to be of minor importance?

The correct answer indicates that 99% of insect species are viewed as having minor importance. This reflects the understanding that while there is an immense diversity of insect species—estimated to be in the millions—only a small fraction of these species significantly impact human activity, agriculture, or ecosystems in either a positive or negative way.

Insects play various roles in the environment, such as pollination, decomposition, and serving as a food source for other animals. However, when it comes to pests that affect crop production or transmit diseases, these issues are typically caused by a select few species. Thus, the majority—meaning 99%—of insects do not cause major concerns or problems, hence they are classified as of minor importance. This understanding emphasizes the necessity to focus on effective management and control strategies primarily for the small percentage of insects that pose significant threats.
