Abstract:

The possible presence of chemosensilla in the ovipositor region has been investigated in three different pest insect species by means of the standard tip-recording electrophysiological technique. Results showed that hair-like structures responding to chemical stimulation were located at the lower-inner edge of the anal leaflets in Tabanus nigro Macq. as well as in Chrysops fuliginosus Wied, whereas peg-like chemosensilla proved to be located in two longitudinal grooves at the apical portion of the ovipositor in Rhagoletis pomonella Walsh.. At least 3 chemosensory units could be detected in each chemosensillum tested. No hair-or peg-like structure on the ovipositor region other than that we described showed any chemosensory responsiveness.
