FIELD TRIALS WITH CERTAIN ENTOMOPATHOGENS AND INSECTICIDES AGAINST BERSEEM GRASSHOPPER Euprepocnemis plorans (CHARP.) (ORTOPTERA: ACRIDIDAE) [PDF]

Journal of Plant Protection and Pathology, 2015
Three field trials were conducted to evaluate three entomopathogens (Metarhizium acridum, Beauveria bassiana and Nosema locustae) and two chemical insecticides (Indoxacarb and Fipronil) against berseem grasshoppers Euprepocnemis plorans (Charp.). Results

A Mutant of Metarhizium anisopliae var. acridum with Enhanced Submerged Conidiation [PDF]

World Journal of Microbiology and Biotechnology, 2006
An insertional mutant of Metarhizium anisopliae is described with enhanced submerged conidiation. In a 500 ml submerged culture, this mutant produces a mean of 4.05 × 108 propagules  ml−1 from an inoculum of 1 × 106 conidia, where the parental strain accumulates only 3.75 × 104 propagules  ml−1.

Insecticide Use against Desert Locust in the Horn of Africa 2019–2021 Reveals a Pressing Need for Change

Agronomy, 2023
The desert locust upsurge in the Horn of Africa over 2019–2021 led to a total of 1.6 million ha being treated with broad-spectrum organophosphate and pyrethroid insecticides in Ethiopia and Kenya, while insect growth regulators and the entomopathogenic ...

Phenotypic variation and genomic variation in insect virulence traits reveal patterns of intraspecific diversity in a locust‐specific fungal pathogen

Journal of Evolutionary Biology, Volume 36, Issue 10, Page 1438-1454, October 2023., 2023
Exploring the intricate world of host–pathogen interactions, our study delves into the diverse landscape of Metarhizium acridum, a specialist fungal entomopathogen. By dissecting patterns of virulence, growth dynamics, and genomic variability across its geographic distribution, we unveil compelling evidence of intraspecific diversity.

NOVEL PESTECIDES FOR DESERT LOCUST Schistocerca gregaria (Forskal) CONTROL [PDF]

Journal of Plant Protection and Pathology, 2014
The effect of Abamectin and D-limonene was evaluated against desert locust nymphs under laboratory and field conditions, as well as the combined effect of both insecticides with the fungus Metarhizium anisopliae var.

The emerging role of septins in fungal pathogenesis

Cytoskeleton, Volume 80, Issue 7-8, Page 242-253, July-August 2023., 2023
Abstract Fungal pathogens undergo specific morphogenetic transitions in order to breach the outer surfaces of plants and invade the underlying host tissue. The ability to change cell shape and switch between non‐polarised and polarised growth habits is therefore critical to the lifestyle of plant pathogens.

Unearthing the plant–microbe quid pro quo in root associations with beneficial fungi

New Phytologist, Volume 234, Issue 6, Page 1967-1976, June 2022., 2022
Summary Mutualistic symbiotic associations between multicellular eukaryotes and their microbiota are driven by the exchange of nutrients in a quid pro quo manner. In the widespread arbuscular mycorrhizal (AM) symbiosis involving plant roots and Glomeromycotina fungi, the mycobiont is supplied with carbon through photosynthesis, which in return supplies

Can it be all more simple? Manufacturing aflatoxin biocontrol products using dry spores of atoxigenic isolates of Aspergillus flavus as active ingredients

Microbial Biotechnology, Volume 15, Issue 3, Page 901-914, March 2022., 2022
Atoxigenic strain‐based aflatoxin biocontrol product Aflasafe is normally manufactured by coating carrier sorghum grains with a suspension of freshly produced spores of the active ingredients mixed with a polymer and a dye. We describe a process by which spores were produced and dried in Nigeria and transported to Senegal for manufacturing 190 tons of ...

A novel effector, CsSp1, from Bipolaris sorokiniana, is essential for colonization in wheat and is also involved in triggering host immunity

Molecular Plant Pathology, Volume 23, Issue 2, Page 218-236, February 2022., 2022
CsSp1, a virulent effector in Bipolaris sorokiniana, also triggers immunity in plant cells. Abstract The hemibiotrophic pathogen Bipolaris sorokiniana causes root rot, leaf blotching, and black embryos in wheat and barley worldwide, resulting in significant yield and quality reductions.
