COTTON LINT CONTAMINATION WITH SWEETPOTATO WHITEFLY,BEMlSIA TABACI (GENNADIUS) HONEYDEW

摘要

Laboratory studies were conducted on honeydew production by sweetpotato whitefly (SPW), Bemisia tabaci (Gennadius).All stages of the insect, except eggs, produced honeydew. Trehalulose was produced by nymphal instars and adults. Stickyspots produced in the sticky cotton thermodetector were highly correlated to increasing amounts of honeydew sugars.
