. Behavioural habituation† of Schistocerca gregaria Forskål fifth instar larvae to a feeding deterrent, nicotine hydrogen tartrate (NHT), is described. An attempt was made to differentiate between various factors possibly involved in the induction of this behavioural habituation. Sensory stimulation (through maxillary palp), cannulation of NHT into the crop, and its administration by gelatine capsules placed into the oesophagus each resulted in behavioural habituation, but in the latter two cases a sole induction via post‐ingestional input is not completely proven. Injection of NHT into the haemolymph did not induce habituation. It is concluded that habituation via sensory stimulation is a central phenomenon.
