Chemoreception of sugars and amino acids in female fourth and sixth instars of the spruce budworm, Choristoneura fumiferana (Clem.)

Gustatory responses to several sugars and l-amino acids in two age groups of Choristoneura fumiferana (Clem.) larvae were studied using electrophysiological methods. Sensitivity to the stimuli was assessed by stimulating the medial and lateral styloconic sensilla of the galea. Of the twelve common s
