BIOCHEMICAL STUDIES ON THE EFFECT OF Metarhizium anisopliae VAR acridum INFECTION IN THE DESERT LOCUST, Schistocerca gregaria FORSKAL [PDF]

Journal of Plant Protection and Pathology, 2009
Fifth instar nymphs of the desert locust Schistocerca gregaria Forskal were topically treated with 5µl of an oil-based spore suspension of the entomopathogenic fungus Metarhizium anisopliae var acridum. Haemolymph samples were collected from both control

Optimum Flight Height for the Control of Desert Locusts Using Unmanned Aerial Vehicles (UAV)

Drones, 2023
Desert locust is one of the most destructive migratory pest in the world. Current methods of control rely on conventional chemical insecticides during invasion.

Production of destruxins from Metarhizium spp. fungi in artificial medium and in endophytically colonized cowpea plants. [PDF]

PLoS ONE, 2014
Destruxins (DTXs) are cyclic depsipeptides produced by many Metarhizium isolates that have long been assumed to contribute to virulence of these entomopathogenic fungi.

MaNCP1, a C2H2 Zinc Finger Protein, Governs the Conidiation Pattern Shift through Regulating the Reductive Pathway for Nitric Oxide Synthesis in the Filamentous Fungus Metarhizium acridum

Microbiology Spectrum, 2022
Asexual sporulation is the most common reproduction mode of fungi. Most filamentous fungi have two conidiation patterns, normal conidiation and microcycle conidiation, which may be regulated by nutritional conditions.

Exposure ofMetarhizium acridummycelium to light induces tolerance to UV-B radiation [PDF]

FEMS Microbiology Letters, 2016
Metarhizium acridum is an entomopathogenic fungus commonly used as a bioinsecticide. The conidium is the fungal stage normally employed as field inoculum in biological control programs and must survive under field conditions such as high ultraviolet-B (UV-B) exposure.

Dose-dependent behavioural fever responses in desert locusts challenged with the entomopathogenic fungus Metarhizium acridum. [PDF]

Sci Rep, 2018
AbstractBehavioural fever is a common response to immune challenge in ectotherms and confers survival benefits. However, costs accrue rapidly as body temperature rises. Thus, the magnitude of adaptive fever responses might reflect the balance of costs and benefits.

Enhancing the Biocontrol Potential of the Entomopathogenic Fungus in Multiple Respects via the Overexpression of a Transcription Factor Gene MaSom1

Journal of Fungi, 2022
Entomopathogenic fungi play important roles in the control of populations of agricultural and disease vector pests in nature. The shortcomings of mycoinsecticides for pest management in the field cannot be completely overcome by improving single ...

Genetically altering the expression of neutral trehalase gene affects conidiospore thermotolerance of the entomopathogenic fungus Metarhizium acridum

BMC Microbiology, 2011
Background The entomopathogenic fungus Metarhizium acridum has been used as an important biocontrol agent instead of insecticides for controlling crop pests throughout the world.

Tryptamine accumulation caused by deletion of MrMao-1 in Metarhizium genome significantly enhances insecticidal virulence.

PLoS Genetics, 2020
Metarhizium is a group of insect-pathogenic fungi that can produce insecticidal metabolites, such as destruxins. Interestingly, the acridid-specific fungus Metarhizium acridum (MAC) can kill locusts faster than the generalist fungus Metarhizium robertsii

A Rapid Method for Measuring In Vitro Growth in Entomopathogenic Fungi

Insects, 2023
Quantifying the growth of entomopathogenic fungi is crucial for understanding their virulence and pathogenic potential. Traditional methods for determining growth, such as biomass determination or colony growth area, are time-consuming and quantitatively
