A South African Scenario: Structure and Function of Peptides of the Adipokinetic Hormone Family of the Brown Locust, Locustana pardalina, and the Putative Role of These Peptides in Plague Management. [PDF]

open access: yesArch Insect Biochem Physiol
1. The brown locust produces the three adipokinetic hormones Locmi‐AKH‐I, ‐II and ‐III found also in the migratory locust. 2. Flight is characterised by differential changes in haemolymph carbohydrate and lipid levels. 3. Modelling ligand‐receptor binding is proposed as important step to a new strategy to combat the brown locust.
