What term describes a division of classes used to identify distinct groups within a class, such as beetles within Insecta?

The term that describes a division of classes used to identify distinct groups within a class, such as beetles within Insecta, is referred to as "Order." In biological classification, the hierarchy starts with the broadest category (Domain) and becomes more specific down to the species level.

In this hierarchy, "Order" is one of the major ranks and includes one or more families. For example, the order Coleoptera encompasses all beetles, which are a specific group of insects classified under the class Insecta. Each order consists of various families that share common characteristics, thus providing a structured way to categorize living organisms based on their evolutionary relationships.

Understanding the classification system is essential for pest control professionals as it allows them to recognize and differentiate between various pest species effectively, enabling informed control strategies.
