Abstract:
Background and Objective: The Taify cultivar of grapevine (Vitis vinifera L.) is the second important economical fruit after pomegranate at high altitudes of the Taif region in Saudi Arabia. The grapevine trees are infested with different piercing-sucking insect pests especially aphids, whiteflies and thrips. The purpose of this study was to evaluate the ability of an indigenous endophytic entomopathogenic fungus, Beauveria bassiana to control the important piercing-sucking insect pests on grapevines. Materials and Methods: This investigation was carried out through 5, 10 and 15 day intervals between sprays for controlling Aphis illinoisensis, Bemisia tabaci and Frankliniella occidentalis with a concentration of 6×106 conidia mL1 under field conditions. Results: The higher infestation in the untreated control was by aphids followed by whitefly and thrips. At the end of the experiment in the treated trees, aphid and whitefly reduction percentages with 5 day intervals of sprays (98.5 and 96.12%, respectively) were not significantly different from 10 day intervals (95.17 and 91.81%, respectively) while these reductions were significantly higher than the reduction occurred by 15 day intervals of sprays (65.93 and 44.51%, respectively). Meanwhile, the 3 intervals of sprays did not differ significantly in the thrips reduction occurred by them with a range from 93.62-96.46%. Conclusion: This indigenous B. bassiana as 6×106 conidia mL1 with 10 day intervals of the spray-on grapevine can suppress the piercing-sucking insect pests. This also will participate in grapevine organic production and furthermore, it could replace the chemical treatment.
