Feeding modulation in insects through factors in the hemolymph

In insect hemolymph, many factors are present that can influence feeding motivation, such as lipids, carbohydrates, and other metabolites. Levels of these hemolymph factors fluctuate according to metabolic, nutrient and feeding states, eventually affecting feeding motivation and consequent regularly occurring feeding cycles. Such fluctuations contribute to energy homeostasis and innate feeding behavior in insects possibly by endocrine systems. Ultimately, orchestration of bioactive factors in the hemolymph modulate feeding motivation and nutrient selective behavior in insects. Fluctuation of the levels of hemolymph factors can modulate feeding motivation in insects possibly via endocrine control.
