An Integrated Assessment Approach for Socio‐Economic Implications of the Desert Locust in Eastern Africa

Earth's Future, Volume 12, Issue 4, April 2024.
Abstract Desert locust (Schistocerca gregaria) infestations cause significant damage to crops and pastureland, impeding food security and livelihoods globally. In recent years, some East African countries have suffered severe desert locust outbreaks, causing significant harm to agriculture and local communities.

An updated and validated model for predicting the performance of a biological control agent for the oriental migratory locust

Pest Management Science, Volume 80, Issue 2, Page 442-451, February 2024.
The biopesticide performance model uses readily available satellite temperature data to accurately predicted the time it takes to kill a population of the oriental migratory locust. This model can be used to assess, at a fine scale, the appropriateness of biopesticides for controlling the oriental migratory locust.

Two‐speed genomes of Epichloe fungal pathogens show contrasting signatures of selection between species and across populations

Molecular Ecology, Volume 33, Issue 4, February 2024.
Abstract Antagonistic selection between pathogens and their hosts can drive rapid evolutionary change and leave distinct molecular footprints of past and ongoing selection in the genomes of the interacting species. Despite an increasing availability of tools able to identify signatures of selection, the genetic mechanisms underlying coevolutionary ...

UvHOS3‐mediated histone deacetylation is essential for virulence and negatively regulates ustilaginoidin biosynthesis in Ustilaginoidea virens

Molecular Plant Pathology, Volume 25, Issue 2, February 2024.
UvHOS3 in Ustilaginoidea virens controls histone deacetylation at H3K9, H3K18, H3K27 and H4K8 and positively regulates fungal growth and pathogenicity, but negatively modulates mycotoxin biosynthesis. Abstract Ustilaginoidea virens is the causal agent of rice false smut, which has recently become one of the most important rice diseases worldwide ...

Reduction in host-finding behaviour in fungus-infected mosquitoes is correlated with reduction in olfactory receptor neuron responsiveness

Malaria Journal, 2011
Background Chemical insecticides against mosquitoes are a major component of malaria control worldwide. Fungal entomopathogens formulated as biopesticides and applied as insecticide residual sprays could augment current control strategies and mitigate ...
