Survival of Smaller Brown Planthopper, Laodelphax Striatellus Fallen, on Carbohydrate Solutions : Hemiptera : Delphacidae

Abstract

Suitability of dietary carbohydrate for smaller brown planthopper, Laodelphax striatellus, was examined. Sucrose solution at the concentration of 5 % gave the best survivorship. Glucose gave the second best planthopper performance. Fructose, maltose, raffinose, trehalose, and soluble starch reduced surviving time of the planthopper drastically. Mixtures of glucose and fructose were inferior to sucrose of equimolar concentrations. No synergic nitritional effect was obtained from the mixtures of sucrose and maltose. © 1969, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY. All rights reserved.
