Efficacy of Beauveria bassiana applications on coffee berry borer across an elevation gradient in Hawaii
Biocontrol Science and Technology 28 (11), 995-1013
Abstract: The effect of three rates of a commercial formulation of Beauveria bassiana Strain GHA was evaluated against the coffee berry borer (CBB) Hypothenemus hampei Ferrari (Coleoptera: Curculionidae: Scolytinae), at three commercial coffee farms located at different altitudes on the island of Hawaii. H. hampei infestation and natural prevalence of B. bassiana increased with the elevation. At 145 metres above sea level (Farm 1), beetle infestation was 3.9%; at 538 m (Farm 2), beetle infestation was 12.2%; and at 768 m (Farm 3) infestation was 22.3%. The prevalence of natural B. bassiana killing CBB was 5.5% on Farm 1, 3.3% on Farm 2 and 23.1% on Farm 3. Monthly applications of B. bassiana resulted in no significant differences in levels of CBB infestation among treatments. Similarly, rates of infested berries with visually detectable signs of B. bassiana were similar among the B. bassiana treatments, ranging from 0.44% to 4.24%, and those percentages were larger than the treatments without B. bassiana. The percentage of females killed by Beauveria ranged from 69% to 95%. Effect of dose of BotaniGard® ES was reduced when beetles were in C position compared to A and B positions. B. bassiana can be an important component of an integrated pest management program for CBB.
