Abstract:

1. 1. The effect of twenty-five sugars and related compounds on the feeding response of larvae of Spodoptera littoralis was investigated using the Styropor method. 2. 2. Styropor lamellae were treated with 0·25 and 0·0625 M solutions. The weight of the lamellae consumed and the number and weight of fecal pellets, served as criteria of feeding stimulation. 3. 3. Sucrose, raffinose, maltose, d-fructose, melibiose and d-glucose were found to be very active as phagostimulants. 4. 4. The survival of larvae which had fed on sugar-treated Styropor for 3 days was the longest on sucrose, maltose, glucose, fructose, raffinose and melezitose. 5. 5. Some of the sugars were assayed in pairs in different choice and no-choice experiments; no antagonistic or inhibitory effects were found. © 1972.
