- Abstract
The dual-choices tests of behavioral test were used to study the gustatory behavioral responses to caffeine of Helicoverpa armigera larvae and H. assulta larvae. Electrophysiological responses were studied by electrophysiological tipp recording. Behavioral experiments showed that caffeine was a feeding deterrent for both larvae, but it showed a stronger feeding detening effect on the oligophagous H. assulla. The electrophysiological tip-recording results showed that both H. armigera larvae and H. assulta larvae had one caffeine-sensitive feeding deterrent neuron at the medial sensiila, and the electrophysiological pulse response of H. assulta larvae was significantly stronger than that of H. armigeea larvae. Therefore, caffeine had a stronger feeding detemng effect on the oligophagous H. assulta than the polyphagous H. armigera. The difference in behavioral effect was closely related to the sensitivity of to caffeine the feeding detenrent neurons at the medial sensiila.
