| This study aims to evaluate the control efficacy of greenhouse whitefly by co-application of entomopathogenic fungus Lecanicillium muscarium hybrid strain 2aF43 and greenhouse whitefly parasitoid Encarsia formosa, and to reveal the interaction between both natural enemies. Although, the emergence rate of adult greenhouse whitefly reached 93.2% in control plot, co-application plot indicated significantly lower emergence rate (4.2%). Co-application plot showed higher fungal infection compared with singularly L. muscarium inoculated plot. Parasitization rate in singularly E. formosa released plot reached 81.7% and emergence rate of parasitoid was 72.1%, but lower parasitization and emergence rate of parasitoid (13.2% and 2.0% respectively) were detected on... |

| 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. We observed two species: Trialeurodes vaporariorum (Westwood) and the Bemisia tabaci complex (Gennadius). 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... |
