Eleetrophysiological recordings from taste sensilla of larvae of Chilo partellus (Swinhoe), Eldana saccharina Wlk. and Maruca testulalis (Geyer) during stimulation with various plant substances revealed that in the medial and lateral maxillary sensilla styloconica of each of these three species a NaCl, water and sucrose sensitive cell is present. In the medial styloconic sensilla of C. partellus, an additional chlorogenic acid sensitive cell occurs. Chilo partellus and E. saccharina appeared to be more sensitive to sucrose than M. testulalis. In all three species, the lateral sensilla styloconica are more responsive to sucrose and less responsive to NaCl than the medial ones.
