The parasitoid Psyllaephagus bliteusRiek (Hymenoptera: Encyrtidae), entomopathogenic fungi, and chemical insecticides are the main strategies to manage the eucalypts pest Glycaspis brimblecombeiMoore. The objective of this study was to isolate and to identify entomopathogenic fungi, collected from Bemisia tabaciGennadius adults in soybean and tomato crops, and from soil samples in eucalypts, soybean, and native forest areas to evaluate their potential to manage G. brimblecombei. Twelve Beauveriaand Cordycepsisolates were selected and compared with the commercial products Boveril Beauveria bassiana Bals.(Hypocreales: Cordycipitaceae), Metarril Metarhizium anisopliaeMetschn. (Hypocreales: Clavicipitaceae), and Octane Cordyceps fumosoroseaWize (Hypocreales: Cordycipitaceae) and their respective strains. The fungal isolates were diluted in 0.1% aqueous Tween 80 at a concentration of 1.0 × 108conidia/ml and sprayed on the G. brimblecombeinymphs with or without lerps. Pest mortality was higher and the TL50and TL90lower with the isolates LCBPF 11 C. javanicaFrieder. & Bally (Hypocreales: Cordycipitaceae), LCBPF 12 (C. fumosorosea), and LCBPF 67 (C. fumosorosea) from B. tabaciadults. Fungi of the genera Beauveriaand Cordycepsdeveloped and caused high mortality of G. brimblecombeinymphs with lerps. The B. bassiana, C. cateniannulataLiang (Hypocreales: Cordycipitaceae), C. fumosorosea, C. javanica, and M. anisopliaeisolates showed potential to manage G. brimblecombei. The lerp of this insect enhances entomopathogenic fungus development as a source of inoculum accelerating G. brimblecombeinymph mortality. Entomopathogenic fungi isolated from insects and soils are effective against G. brimblecombeiand the presence of the lerp of this insect increases the effectiveness of its control. |
