Feeding in Rhodnius prolixus: Mouthpart Activity and Salivation, and their Correlation with Changes of Electrical Resistance,
TORONTO UNIV (ONTARIO) DEPT OF ZOOLOGY

Detailed observations were made of mouth part movements, salivation and ingestion in Rhodnius prolixus feeding on an artificial diet. Several events not previously described in blood-feeding Hemiptera were recorded these included formation of a salivary collar, continuous salivation during probing, and sampling of diet prior to initiation of gorging. The events during feeding were analysed in detail and correlated with changes in electrical resistance between haemolymph and diet by recording both simultaneously on video-tape using a split-screen television technique.
