Morphophysiological Responses in Eucalyptus Demonstrate the Potential of the Entomopathogenic Fungus Beauveria bassiana to Promote Resistance against the Galling Wasp Leptocybe invasa

The galling insect Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae) is a major limiting factor in the cultivation of drought-tolerant eucalyptus. L. pest eucalyptus plantations, and Beauveria bassiana (Bals.) Vuill (Ascomycota: Hypocreales) being investigated as potential biocontrol agent against this pest. fungus B. can produce metabolites that affect biology survival. Here, we ability entomopathogenic to endophytically develop induce resistance hybrid. In greenhouse under semi-controlled conditions, group seedlings were sprayed with solution containing fungal spores bassiana. uninoculated inoculated infested invasa, their morphometric responses, gas exchange, chlorophyll indexes assessed. number leaves height plants was higher than those plants. mean CO2 assimilation rate (A) transpiration (E) for showed chl b contents. Compared plants, developed much fewer galls, while some only scar formations where deposited its eggs. These results indicated inoculating Eucalyptus promoted invasa. To best our knowledge, first study showing an promote
