1. Behavioural studies show that larvae of Locusta migratoria (L.) can discriminate between certain simple chemicals and between chemicals obtained from plant sources. 2. Electrophysiological tests show that within each sensillum the same neurones respond to different chemicals. 3. The frequency of occurrence of sensilla with enhanced specificity to certain chemicals is investigated. 4. Statistical tests confirm that, despite the variability of response, across-fibre analysis could allow discrimination between chemicals provided an adequate number of senilla are used. 5. The conclusions are discussed in relation to current theories of chemoreceptor functioning.
