The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Increased utilitarian value of invasive species in regions with long invasion history may limit public engagement for invasion control

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Positive perceptions of invasive species can hinder effective management, especially if management efforts that are rooted in scientific theories are misaligned with local ecological knowledge. We documented local ecological knowledge about land invasibility as predicted by invasion biology theories. Participants with greater local ecological knowledge

Body-size influence on defensive behavior of Amazonian moths: an ecophysiological approach

open access: yesBrazilian Journal of Biology
Ectotherm locomotion is restricted by low temperatures, and many species, such as some flying insects, need to achieve thermal thresholds before taking off. Body size influences heat exchange between an animal and the environment.

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

open access: yesPest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Soybean induced resistance to Spodoptera eridania herbivory

open access: yesPest Management Science, EarlyView.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

PCR‐based species identification tools for wireworms (Coleoptera: Elateridae) of economic importance in Canada

open access: yesPest Management Science, EarlyView.
Species‐specific PCR primers and PCR‐based assays were designed for the identification of 15 economically important and difficult to distinguish wireworm pests in Canada. PCR specificity testing and performance assessments confirm the accuracy of the assays.

Potential expanded pollinator distributions in North America under future climate

open access: yesEcological Solutions and Evidence
Pollinator species have declined globally during the last several decades due to a variety of factors, including habitat destruction and degradation, pesticides, disease and climate change.

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

open access: yesPest 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.

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

open access: yesPest 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.

Validation of a novel bioassay method for the evaluation of the activity of slow‐acting insecticides on tomato borer Phthorimaea absoluta

open access: yesPest Management Science, EarlyView.
Extended bioassays revealed that azadirachtin and spirotetramat show strong delayed effects against Phthorimaea absoluta, underestimated by the standard Insecticide Resistance Action Committee (IRAC) method 022 protocol. Incorporating long‐term exposures is essential to accurately assess slow‐acting insecticides and improve resistance management ...
