BackgroundBiological control of insects is the current goal of modern researches to avoid using the harmful chemicals. Some fungi are capable of infecting and killing insects and, hence, are commonly known as entomopathogenic fungi (EPF). On the other hand, some insects can kill harmful fungal strains using their products such as peptides. Hence, t...

BackgroundIn this study, commercial bioinsecticides including entomopathogenic fungi, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, and Spinetoram active ingredient insecticide were evaluated against the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) larvae.Main bodyThe active ingredients were pr...

Subtilisin-like Pr1 proteases of insect-pathogenic fungi are a large family of extracellular cuticle-degrading enzymes that presumably determine a capability of hyphal invasion into insect hemocoel through normal cuticle infection, but remain poorly understood although often considered as virulence factors for genetic improvement of fungal potentia...

BackgroundThe fungus, Beauveria bassiana (Bals.) Vuil., is one of the most important entomopathogenic fungi (EPFs). Recently, its new role was discovered in nature, to be an endophyte in plants. It has been reported as an endophytic fungus in many monocotyledonous and dicotyledonous plants.Main bodyThe study was conducted to evaluate the ability of...

BackgroundStudying the ecology of biocontrol-agents is a prerequisite to effectively control medfly (Ceratitis capitata (Diptera: Tephritidae)) with entomopathogenic fungi. In this context, factors affecting the occurrence and distribution of medfly-associated entomopathogenic-fungi were studied. Soil samples (22) were collected from natural and cu...

Mosquitoes transmit many parasites and pathogens to humans that cause significant morbidity and mortality. As such, we are constantly looking for new methods to reduce mosquito populations, including the use of effective biological controls. Entomopathogenic fungi are excellent candidate biocontrol agents to control mosquitoes. Understanding the co...

BackgroundWhitefly, Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae), is one of the most harmful pests in greenhouses and in open fields.Main bodyThe present study aimed to assess in vitro virulence of 3 entomopathogenic fungal strains (EPFs) of Lecanicillium lecanii 3 (V-3), 4 (V-4), and 5 (V-5) against the whitefly, Bemisia tabaci (Genn.) (Hemipte...

BackgroundThe Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is the major insect pest of fruit production worldwide. Chemical control of this pest has induced the selection of resistant medflies populations and negative environmental impact. In addition, the use of pesticides has become an obstacle to the fresh agri...

Three new Ophiocordyceps species with superficial perithecia on Lepidoptera larvae are described: O. campes, O. longistromata, and O. phuwiangensis. Ophiocordyceps longistromata is characterized by long stromata and is closely related to O. campes based on morphological characters and phylogenetic position. Ophiocordyceps phuwiangensis is distingui...
Since its recent establishment in Hawaii, the coffee berry borer (CBB), Hypothenemus hampei (Coleoptera: Curculionidae), threatens yields, quality, and price of coffee production. A limited number of insecticides (primarily Beauveria bassiana) are used to control CBB with minimal disruption in this agroecosystem. We evaluated two insecticide spray ...
