Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Landscape composition influences invertebrate herbivory on flowering forbs in semi-natural grasslands

Basic and Applied Ecology
Landscape-scale land use is important in driving species communities and interactions. However, despite increasing concerns regarding the ecological consequences of insect declines, our understanding of how the relative proportions of different land ...

Genetic Diversity Increases Insect Herbivory on Oak Saplings

PLoS ONE, 2012
A growing body of evidence from community genetics studies suggests that ecosystem functions supported by plant species richness can also be provided by genetic diversity within plant species. This is not yet true for the diversity-resistance relationship as it is still unclear whether damage by insect herbivores responds to genetic diversity in host ...

The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

Insect herbivory and plant adaptation in an early successional community*

Evolution, 2018
To address the role of insect herbivores in adaptation of plant populations and the persistence of selection through succession, we manipulated herbivory in a long-term field experiment. We suppressed insects in half of 16 plots over nine years and examined the genotypic structure and chemical defense of common dandelion (Taraxacum officinale), a ...

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Higher accumulation of mitragynine in Mitragyna speciosa (kratom) leaves affected by insect attack.

PLoS ONE
Kratom leaves are widely consumed by locals to increase their stamina for working longer hours in the field. However, insect damage to the leaves can lead to significant loss of leaf harvest. Despite this, there remains considerable uncertainty regarding

Influence of insect herbivory on plant competition

, 2023
Plant communities are influenced by many factors, such as soil properties, humidity, temperature, resource availability or competition and herbivory. This thesis summarizes current knowledge about insect herbivory and its impact on plant competition in ...

Insect pests in Brassica napus crops: toward ecologically optimized integrated pest management

Pest Management Science, EarlyView.
Ecologically optimized IPM: Integrating landscape, biological, and chemical strategies for enhanced pest management. Key findings: Optimizing canola IPM requires the deliberate alignment of habitat diversification, behavioral conditioning, and evolutionary processes.

Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

Pest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.
