Translocation and survival of trunk injected Beauveria bassiana (Hypocreales: Cordycipitaceae) in healthy date palm trees

Evaluation of Various Inoculation Methods on the Effect of Beauveria bassiana on the Plant Growth of Kiwi and on Halyomorpha halys Infestation: A Two-Year Field Study

“…In our study, the trunk inoculation application treatment (I) was much more efficient than all others; this effect was observed for the first time in kiwifruit cultivation. This is probably because endophytic EPFs act more directly when they inhibit tissues that support their faster movement and dispersal to the rest of the plant's biological organs [50]. Both applications, through injection on the trunk of kiwi trees (I) and on the root (R), are treatment methods from essential plant organs, through which juices and nutrients are moved.…”

“…Both applications, through injection on the trunk of kiwi trees (I) and on the root (R), are treatment methods from essential plant organs, through which juices and nutrients are moved. According to Hussain et al, 2024 [50], the plant tissues of the trunk are a pathway for the easier movement and dispersion of B. bassiana hyphae. Within the tree trunk, B. bassiana can move and colonize endophytically in parenchyma and vascular tissue [51], particularly in the petiole [52] in date palm Phoenix dactylifera (Acerales: Aceraceae).…”

Isolation and characterization of a native strain of the entomopathogenic fungus Beauveria bassiana for the control of the palm weevil Dynamis borassi (Coleoptera: Curculionidae) in the neotropics

“…Since D. borassi and R. palmarum have been recognized as pests of economic importance for the crops of Bactris gasipaes and Cocos nucifera (Bautista-Giraldo et al 2020 ; Gaviria et al 2021 ; Gutiérrez et al 2023 ), the results obtained with the Bv065 strain show great potential for its use in the field, where different dissemination strategies can be employed such as trunk applications (Güerri-Agulló et al 2010 ), passage traps for the inoculation of adults (Dembilio et al 2018 ), release of contaminated males (León Martínez et al 2019 ); where the control objective is the adults. Additionally, exploratory studies have shown the potential use of B. bassiana in endotherapy (i.e., trunk injection) for the control of weevil larvae inside the palms (Sutanto et al 2023 ; Husain et al 2024 ).…”
