Abstract
螺旋粉蝨持續為害聖誕紅35天時，為害率與為害度分別為98%及82%，持續48天時全株葉片枯萎而喪失觀賞價值。為害番石榴植株如連續達4個月時，為害葉率可達64%，果實產量損失為80%。The infestation rate and degree of infestation were 98% and 82% when poinsettia was consecutively attacked by spiralling whiteflies for 35 days. And most of leaves were chlorosis, withered, covered with sooty mold and appeared premature dehiscence on day 48 which made them lost their commercial value. If whiteflies attack guava for consecutive 4 months, the leaf infestation rate reached 64% and caused 80% fruit yield loss.
