Abstract
1. The electrical resistance across the tips of the maxillary palps of Locusta migratoria is high immediately after a feed, but falls to a steady level in about 2 h after feeding. 2. Only a small proportion of the individual sensilla on the domes of the palps respond to chemical stimulation immediately after feeding, but this proportion increases with the period of food deprivation. 3. Gentle manipulation of the tips of non-responsive sensilla causes them to respond. 4. It is suggested that the terminal pores of the sensilla can open and close and that the resistance across the tips of the palps varies inversely with the number of open sensilla. 5. The possible significance of the changes is discussed.This publication has 7 references indexed in Scilit:
