Abstract
Changes in haemolymph biogenic amine levels of the cabbage armyworm , Mamestra brassicae, last instar larvae following injection of octopaminergic insecticides were investigated by using HPLC-ECD. When octopaminergic insecticides, chlordimeform or 2-(4-chloroo- toluidino)-2-oxazoline (AC-6), are injected, 4-tyrosine (TYR-4) is increased 10 min after injection. Clonidine injection also caused an increase of TYR-4. Based on these results, chemically induced insect stress is discussed.Keywords
