Which role does the head of the Department of Entomology represent in the Commission?

The head of the Department of Entomology represents the Commissioner of Agriculture in the Commission. In this context, the Department of Entomology is typically involved with the study and management of insects, which has direct implications for agriculture, pest control, and environmental health. The Commissioner of Agriculture plays a vital role in overseeing agricultural practices and ensuring food safety, which includes dealing with pest management strategies that fall under the purview of entomology.

This connection is critical as pest control measures directly affect crop health and agricultural yields, making the head of this department a key player in guiding policies and practices within the agricultural sector. The other roles listed do not have direct oversight or involvement in agricultural pest management, which clarifies why the Commissioner of Agriculture is the correct choice.
