“…Given that Rhynchophorus has a palm borer lifestyle, the damage is based on larvae survivorship in the host palm trunk coupled with late damage and infestation diagnosis [ 17 ]. Thus, understanding the insect’s behavior is important for the implementation of new control strategies, especially those derived from research on telemetry [ 37 ], semiochemical interference [ 38 , 39 , 40 , 41 ], new secondary metabolites and formulations [ 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ], early infestation detection [ 50 ], novel biopesticides [ 51 , 52 , 53 , 54 ], and natural enemies [ 55 , 56 ].…”

“…Among the entomopathogenic fungi, the Beauveria bassiana and Metharizium anisopliae are relevant for biological pest control of palm borers [ 104 , 105 ]. The fungi can induce mycosis in various niches, leading to epizootics [ 46 , 106 ]. Most of these fungi assemble in a complex of about 90 genera and 700 species [ 107 ] of soil inhabitant species responsible for approximately 80% of insect diseases occurring without propagule ingestion [ 108 , 109 ].…”

Perspectives for Synergic Blends of Attractive Sources in South American Palm Weevil Mass Trapping: Waiting for the Red Palm Weevil Brazil Invasion

Coupling several natural and synthetic lures with aggregation pheromones from the palm weevils Rhynchophorus palmarum and R. ferrugineus reveals a synergy that results in an increase in pest captures. The combined attraction of pure pheromones, ethyl acetate, and decaying sweet and starchy plant tissue increases the net total of mass-trapped weevils. The 2018 entrance of the red palm weevil (RPW) into South America has threatened palm-product income in Brazil and other neighboring countries. The presence of the new A1 quarantine pest necessitates the review of all available options for a sustainable mass-trapping, monitoring, and control strategy to ultimately target both weevils with the same device. The effective lure-blend set for the mass-trapping system will attract weevils in baiting and contaminating stations for entomopathogenic fungi that the same weevils will spread.

“…The endophytic relationship between entomopathogenic fungi and oil palms is an alternative to pest control decreasing the dependence of chemical insecticides. The entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin have been reported infecting the oil palm pests Rhynchophorus palmarum Linnaeus 16 and Rhynchophorus ferrugineus Olivier 17 (Coleoptera: Curculionidae). Although these fungi are found in Chrysomelid beetles in the field, 18,19 there are no studies on their use to control D. neivai .…”

BACKGROUND The potential of Beauveria bassiana and Metarhizium anisopliae isolates obtained from naturally infected oil palm pests was evaluated to control Demotispa neivai as an alternative for organophosphate insecticide use in oil palm crops in Latin America. Two B. bassiana (Bb‐0018 and Bb‐0025) and two M. anisopliae (Ma‐0002 and Ma‐0003) isolates were tested against D. neivai adults for hydrophobicity, virulence, survival, adhesion to host cuticle, and mortality in semi‐field conditions. RESULTS Concentration–mortality bioassays demonstrate that isolates had lethal effect on D. neivai adults with Bb‐0025 [median lethal concentration (LC50) = 3.45 × 107 conidia mL−1] and Bb‐0018 (LC50 = 3.75 × 107 conidia mL−1) being the most effective followed by Ma‐0003 (LC50 = 3.38 × 108 conidia mL−1) and Ma‐0002 (5.33 × 108 conidia mL−1). Adult survival was 99% without exposure to fungal isolates, decreasing to 21.65% in insects exposed to Ma‐0002, 19.41% with Ma‐0003, 20.13% with Bb‐0018, and 0.17% with Bb‐0025. Mortality of D. neivai adults caused by the entomopathogenic fungal isolates was similar in both laboratory and semi‐field conditions. Also, vegetative growth of the entomopathogenic fungal isolates was found in infected D. neivai adults in the field. CONCLUSION Our data suggest that the tested entomopathogenic fungal isolates are effective against D. neivai with potential to be used as biological control agents contributing to the decrease of the use of chemical insecticides to control this oil palm pest. © 2021 Society of Chemical Industry.

This study aimed to isolate and characterize a native strain of Beauveria bassiana, coded as Bv065, showcasing its potential as a biological control agent targeting the palm weevil Dynamis borassi. Originating from a naturally infected D. borassi specimen collected in southwestern Colombia, the fungus underwent molecular identification and was identified as B. bassiana, exhibiting high sequence similarity with known reference strains. The physiological characterization revealed that Bv065 thrived within a temperature range of 25 to 30 °C and a pH range of 6 to 9. Moreover, the key carbon sources that allow optimal growth of the strain were identified through metabolic profiling, including sucrose, D-mannose, and γ-amino-butyric acid. These findings offer strategic insights for scalability and formulation methodologies. Additionally, enzymatic analyses unveiled robust protease activity within Bv065, crucial for catalysing insect cuticle degradation and facilitating host penetration, thus accentuating its entomopathogenic potential. Subsequent evaluations exposed Bv065’s pathogenicity against D. borassi, causing significant mortality within nine days of exposure, albeit exhibiting limited effectiveness against Rhynchophorus palmarum. This study underscores the importance of understanding optimal growth conditions and metabolic preferences of B. bassiana strains for developing effective biopesticides. The findings suggest Bv065 as a promising candidate for integrated pest management strategies in neotropical regions, particularly for controlling palm weevil infestations in coconut and peach palm cultivation. Future research avenues include refining mass production methodologies, formulating novel delivery systems, and conducting comprehensive field efficacy trials to unlock the full potential of Bv065 in fostering sustainable pest management practices. Overall, this study contributes to the growing body of knowledge on entomopathogenic fungi and their pivotal role in biological control, offering nuanced perspectives on eco-friendly alternatives to conventional insecticidal interventions.
