Exploring Costa Rica's fungal trends: Insights from digitized specimens

PLANTS, PEOPLE, PLANET, EarlyView.
Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

Occurrence and Pathogenicity of Indigenous Entomopathogenic Fungi Isolates to Fall Armyworm (Spodoptera frugiperda J. E. Smith) in Western Amhara, Ethiopia

Psyche: A Journal of Entomology
The fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) is widely recognized as an invasive lepidopteran pest in Africa. Adoption of synthetic pesticides remains an option for emergency control of the FAW, but their large-scale use by small-scale ...

Is the Insect Cuticle the only Entry Gate for Fungal Infection? Insights into Alternative Modes of Action of Entomopathogenic Fungi

Journal of Fungi, 2019
Entomopathogenic fungi are the only insect pathogens able to infect their host by adhesion to the surface and penetration through the cuticle. Although the possibility of fungal infection per os was described almost a century ago, there is an information

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]

, 2013
Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

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.

Monitoring spirodiclofen resistance in female Brevipalpus yothersi (Acari: Tenuipalpidae) from citrus orchards in Southeastern Brazil

Agricultural and Forest Entomology, EarlyView.
Spirodiclofen resistance levels in B. yothersi varied geographically across the Brazilian citrus belt, with higher resistance in the central region. Sublethal effects included reduced oviposition, increased non‐viable eggs and disrupted female reproduction.

How Do Group Size and Social Context Affect Per‐Capita Behavioral Responses in a Nasute Termite?

Entomologia Experimentalis et Applicata, EarlyView.
Group living is often assumed to increase individual behavioral activity in eusocial insects through social facilitation. Using controlled bioassays with the termite Nasutitermes corniger, we show that increasing group size instead reduces per‐capita behavioral frequency, consistent with greater behavioral specialization. While antennation and grooming

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Advances and Perspectives of the use of the entomopathogenic fungi beauveria bassiana and metarhizium anisopliae for the control of arthropod pests in poultry production

Brazilian Journal of Poultry Science, 2014
Global poultry production is plagued by a wide variety of arthropods. The problems associated with their chemical control have led to an increasing search for control alternatives, and entomopathogenic fungi seem to be a promising strategy.
