The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is a serious agricultural and ornamental pest worldwide (Salas and Mendoz 1995, Fla. Entomol. 1: 154–160). Adults and immatures of B. tabaci are reported to cause damage to many agricultural crops (Price and Schuster 1991, Fla. Entomol. 1: 60–68). In addition, B. tabaci causes major problems in ornamental crops, mostly in the fall (Osborne and Oetting 1989, Florida Entomol. 3: 408–413). The nymphs and adults of B. tabaci cause direct feeding damage when they suck plant juices (Smith 2009, Pg. 1-8 In New Zealand Greenhouse Tomato Crops, AsureQuality LTD., Auckland, New Zealand). On poinsettias, B. tabaci feeding causes wilting, yellowing of leaves, and mottling. Honeydew secretion by B. tabaci indirectly affects the quality of ornamentals as black sooty mold fungi develop on the honeydew and block photosynthesis (Smith 2009). Bemisia tabaci also causes indirect damage to plants, such as abnormal plant growth...
