The effects of commercial products of entomopathogenic fungus Beauveria bassiana (Naturalis; 0.1%, 0.2% and 0.3%), azadirachtin (NeemAzal T/S; 1% and 2%) and oxymatrin (KingBo; 0.1% and 0.2%) in the control of greenhouse whitefly (Trialeurodes vaporariorum Westwood) on tomato were tested in plastic covered greenhouse. The effects of the bioinsecticides, applied twice at five-day interval, were compared to effects of abamectin (Abastate EW; 0.075%) and thiamethoxam (Actara 25-WG; 0.05%). Tested bioinsecticides reduced the number of larvae by 82-97% (Naturalis), 90-99% (NeemAzal T/S) and 90-96% (KingBo), with the efficacy of greater than 96% according to Henderson-Tilton, in the assessment 16 days after treatment. In the same assessment, achieved percentages in adults reduction and efficacy amounted 24-89% and 67-95% (Naturalis), 85-93% and 93-97% (NeemAzal T/S), 86-96% and 94-98% (KingBo). Percentages of abundance reduction and efficacy after treatment with Abastate EW were 31% and 88% (larvae) and 64% and 84% (adults), while after treatment with Actara 25-WG they amounted 96% and 99% (larvae) and 83% and 92% (adults). The results obtained show that NeemAzal T/S, Naturalis and KingBo can be an efficient alternative to current insecticides in control of T. vaporariorum populations.
