Antennal reception

The sex attractants of Bombyx and Porthetria (and probably those of most Lepidoptera as well as of insects of other orders) are received by olfactory receptors of the male antennae 38), Removal of one male antenna does not prevent detection of the sex scent, but complete removal of both antennae results in loss of such reception. Schneider and coworkers 35, 36) have taken advantage of this antennal reception in developing an electrophysiological method for the bioassay of insect sex attractants which is approximately 1000 times more sensitive than any known behavioral method. They found that stimulation of the sensory cells in the male antenna by exposure to the female sex scent set up a local electrical potential (receptor potential) %hose amplitude is dependent upon the intensity of the stimulant.

The a-D-glucosidase activities in extracts of antennal segments and in the haemolymph of the cotton stainer (Dysdercus intermedius) have been measured quantitatively using aa-trehalose, 4-nitrophenyl a-D-glucopyranoside, sucrose, turanose, maltose, isomaltose, and palatinose as substrates. Three active species were isolated by gel filtration from the segments, but only two from the haemolymph. The results of the isolation were discussed with reference to the hypothesized presence of sugar reception processes in insect gustatory cells.
