Advances in research on autophagy in the maintenance of insect–microbe symbiosis

New Plant Protection, EarlyView.
Autophagy plays a dual regulatory role in insect–microbe symbiotic relationships. Beneficial symbiotic bacteria in insects participate in nutrient exchange via the TOR pathway, whereas pathogenic microbes induce immune defense through the AMPK pathway. Autophagy‐related genes regulate development and pathogen clearance during this process.

Mycoviruses infecting the endophytic and entomopathogenic fungus Tolypocladium cylindrosporum [PDF]

Virus Research, 2011
A mixed virus infection in a strain of the endophytic and entomopathogenic fungus Tolypocladium cylindrosporum was deduced from a study of the transmission to conidia of several double-stranded RNA (dsRNA) elements. The transmission rates of each dsRNA were different, and monosporic isolates harbouring different combinations of the original set of six ...

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Surface characteristics of the entomopathogenic fungus Beauveria (Cordyceps) bassiana [PDF]

Microbiology, 2007
Marked differences in surface characteristics were observed among three types of single-cell propagules produced by the entomopathogenic fungus Beauveria bassiana. Atomic force microscopy (AFM) revealed the presence of bundles or fascicles in aerial conidia absent from in vitro blastospores and submerged conidia.

Management of the Egyptian alfalfa weevil, Hypera brunneipennis (Boheman) (Coleoptera: Curculionidae), in the alfalfa, Medicago sativa L., using the entomopathogenic fungus, Beauveria bassiana (Balsamo) Vuillemin

Egyptian Journal of Biological Pest Control, 2019
Larval and adult populations of the Egyptian alfalfa weevil (EAW) Hypera brunneipennis (Boheman) (Coleoptera: Curculionidae) was monitored after application of the entomopathogenic fungus Beauveria bassiana in the alfalfa field (Medicago sativa L.) in ...

Susceptibility of adult female Aedes aegypti (Diptera: Culicidae) to the entomopathogenic fungus Metarhizium anisopliae is modified following blood feeding

Parasites & Vectors, 2011
Background The mosquito Aedes aegypti, vector of dengue fever, is a target for control by entomopathogenic fungi. Recent studies by our group have shown the susceptibility of adult A. aegypti to fungal infection by Metarhizium anisopliae.

Commercial Product Based on Metarhizium Anisopliae Affects Survival, Midgut Morphology, and Behavior in the Stingless Bee Scaptotrigona depilis (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
