| Whiteflies of economic importance are polyphagous, being able to develop on a large number of cultivated and spontaneous plants. We recorded the whitefly species on vegetable and flower crops and the wild plants associated, under greenhouse and field conditions, for two years.

T vaporariorum was recorded on 24 plant species (11 families), 12 and 8 of which are new hosts in Argentina and in the world, respectively. The B. tabaci complex was recorded only on flower production systems, on 19 plant species (11 families), 14 and 7 of which are new hosts in Argentina and in the world, respectively. The crops Glycine max (L.) and Chrysanthemum morifolium... |
