Insect metabolism refers to the biochemical processes that take place in insects to obtain, convert, and use energy from their food sources for growth, development, reproduction, and other physiological functions. This area of research focuses on understanding how insects digest, absorb, and utilize nutrients, as well as how they regulate their energy metabolism in response to changing environmental conditions. By studying insect metabolism, researchers can gain insights into the physiological mechanisms that control insect growth, survival, and reproduction, which can help in developing more effective pest control strategies and understanding the impact of environmental stressors on insect populations.
