Which caste of subterranean termites is responsible for reproduction?

The caste responsible for reproduction in subterranean termites is the reproductives. This caste consists primarily of the king and queen termites, which are specifically designated for mating and producing offspring. The role of the reproductives is crucial for the establishment and growth of a termite colony, as they ensure the continuation of the population through their reproductive activities.

In a termite colony, the soldiers serve to protect the colony from predators and threats, while the workers are responsible for foraging for food, caring for the young, and maintaining the nest. Although both soldiers and workers play essential roles in the survival and functioning of the colony, they do not engage in reproduction, which is why the reproductives are distinct in their primary responsibility. Alates, or winged reproductives, are often referred to when discussing the potential for new colonies, as they are the ones that leave the current colony to mate and establish new colonies. However, the term "reproductives" commonly includes both the alates and the primary king and queen that stay within the colony to produce offspring.
