用不同浓度的蔗糖溶液饲喂舞毒蛾幼虫。水被用作对照。蔗糖的味觉阈值为0.1M。葡萄糖阈值为0.5M。HCl阈值为0.05M。不同种类的凤蝶（Papilio polyxenes）、绿黄裳蛾（Diacrisia virginica）、绿黄裳蛾（Estigmene acraea）、黄裳蛾（Samia cecropia）、黄裳蛾（Isia isabella）和真海蜇（Euchaetias egle）的幼虫具有相同的阈值。外部温度，幼虫的年龄和终末器官的疲劳似乎不影响阈值。E.乙醇对小麦蛾幼虫的毒性为55 mg/kg。升分别味觉器官位于上咽部和下咽部。嗅觉器官位于触角和上颌骨。影响幼虫选择食物植物的主要因素是味觉和嗅觉。
Porthetria dispar larvae were fed sucrose solutions of different concns. Water was used as a control. The taste threshold for sucrose is .1M. The dextrose threshold is .5M. The HCl threshold is .05M. Larvae of Anosia plexippus, Papilio polyxenes, Diacrisia virginica, Estigmene acraea, Samia cecropia, Isia isabella, and Euchaetias egle have the same thresholds. External temp., age of larvae, and fatigue of end organs do not appear to affect the thresholds. The olfactory threshold of E. egle larvae for ethyl alcohol is 55 mg./liter. The organs for taste are located in the epi- and hypopharynx. and olfactory organs are located in the antennae and maxillae. The primary factors influencing food plant choice by larvae are taste and smell.
