 It is believed that AKH does not only aid flight in insects, but it has also been shown that an increase in AKH can lead to stronger immune responses in locusts.One group have performed experiments where locusts received an injection including AKH and lipopolysaccharide (LPS) – an immune elicitor found in the cell walls of bacteria – led to a stronger immune response than locusts which only received an LPS injection.This implies that lipid mobilisation by AKH can have a variety of uses for energy dynamics within insects and may be important in a range of functions that are related to insect survival.
