BackgroundThe fungus Beauveria bassiana is widely used for agronomical applications, mainly in biological control. B. bassiana uses chitinase enzymes to degrade chitin, a major chemical component found in insect exoskeletons and fungal cell walls ...

Nineteen Brassica accessions were screened for antibiosis resistance to Brevicoryne brassicae. Significant variation in resistance was identified. Detailed bioassays suggest that varietal effects upon aphid pre‐reproductive period conferred observed resistance.

Pareto-efficient biological pest control enable high efficacy at small costs [PDF]
Biological pest control is increasingly used in agriculture as a an alternative to traditional chemical pest control. In many cases, this involves a one-off or periodic release of entomopathogens.

Ecosystem services provided by spiders
ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.

Enhancement of Bacillus thuringiensis toxicity by feeding Spodoptera littoralis larvae with bacteria expressing immune suppressive dsRNA [PDF]
RNAi interference (RNAi) for insect pest control is often used to silence genes controlling vital functions, thus generating lethal phenotypes. Here, we propose a novel approach, based on the knockout of an immune gene by dsRNA-expressing bacteria as a ...

Host plants and experimental warming impact fitness and infection outcomes in a migratory butterfly
Host plant species interacted with temperature treatment to shape monarch survival and infection probabilities. Temperature modified the expected role of tropical milkweed, which did not confer OE resistance to monarchs under elevated temperatures.

Construction and performance of a novel capture-mark-release moth trap [PDF]
Mark-recapture studies can provide important information about moth movement as well as habitat preference across a landscape, but to date, such studies tend to be species-specific or require labor-intensive methodologies.

Glycoproteomics and Its Role in Understanding Bacterial O‐Linked Glycosylation
ABSTRACT Protein glycosylation is now recognized as a ubiquitous process observed in all domains of life. Within bacterial species, carbohydrates can be attached to multiple residues with glycosylation of serine, threonine, or tyrosine residues via their hydroxyl side chains referred to as O‐linked glycosylation.
