Gutiérrez-Flores, L. López-Reyes, A. Mauricio-Gutiérrez, M. Carcaño-Montiel, E. Portillo-Manzano, L. Gómez-Velázquez
ABSTRACT Pathogenic fungi that cause defoliation in different pine species, including Pinus patula, have been reported. The most common practice for controlling these pathogens is the use of fungicides, which have adverse environmental consequences. The objective of this study was to evaluate an alternative for pathogen control without affecting the ecosystem. Bacteria with antifungal activity obtained

First report of Metarhizium anisopliae s.l. action on gastrointestinal ruminant nematodes in the free-living stage and its persistence in soil Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-05-09 Ially de Almeida Moura, Inês dos Santos Pereira, Raoni Andrade Pires, Ossival Lolato Ribeiro, Caio Márcio de Oliveira Monteiro, Leandro de Souza Rocha, Wendell Marcelo de Souza Perinotto
ABSTRACT The fungus Metarhizium anisopliae is one of the most studied biological control agents in parasite control programs, especially when aiming the control of arthropods. Yet, studies using this biological agent to control gastrointestinal nematodes in ruminants are scarce. The present study evaluated the efficacy of the entomopathogenic fungus Metarhizium anisopliae sensu lato (s.l.) formulated

Microbial volatilome in food safety. Current status and perspectives in the biocontrol of mycotoxigenic fungi and their metabolites Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-05-08 Zahoor Ul Hassan, Safa Oufensou, Randa Zeidan, Quirico Migheli, Samir Jaoua
ABSTRACT Fungal infection and mycotoxins contamination in food and feed products cause significant economic losses to the food and agricultural industry. Although the efficacy of synthetic fungicides is unquestionable, there are serious issues associated with their application in agriculture. Improper and/or prolonged application of these products may cause the emergence of resistant fungal populations

Host preference and development of Habrobracon hebetor on larvae of Arenipses sabella and Ephestia cautella Biocontrol Sci. Technol. (IF 1.4) Pub Date : 2023-05-08 Amany Nabeih Mansour
ABSTRACT Habrobracon hebetor Say (Hymenoptera: Braconidae) is an larval ectoparasitoid, mainly of pyralid moths. The almond moth, Ephestia cautella Walker and the greater date moth, Arenipses sabella Hampson are two economic pyralid pests of date palm that were found to be attacked by the parasitoid. Although parasitised larvae of A. sabella are often encountered in the field, no data were available
