Effects of climate change on phenologies and distributions of bumble bees and the plants they visit

Ecosphere, 2016
Surveys of bumble bees and the plants they visit, carried out in 1974 near the Rocky Mountain Biological Laboratory in Colorado, were repeated in 2007, thus permitting the testing of hypotheses arising from observed climate change over the intervening 33‐

Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Comparison of seasonal viral prevalence supports honey bees as potential spring pathogen reservoirs for bumble bees

Ecosphere
Bee declines pose a serious risk to agricultural sustainability, wild plant diversity, and the commercial bee industry, generating local and global concerns about bee health. Parasites, including micro‐parasites and macro‐parasites, negatively impact bee

Using respiratory physiology techniques in assessments of pesticide effects on bees

Julius-Kühn-Archiv, 2018
The determination of sub-lethal effects of pesticides on beneficial insects is challenging topic because the vast number of different possible endpoints. Traditionally measured endpoints reflect the basic outcome but do not give any information about the

Bumble bee nest thermoregulation: a field study

Journal of Apicultural Research, 2023
Careful control of brood temperature is important for successful colony development in social insects. Six bumble bee colonies of six common Central European species (B. hypnorum, B. hortorum, B. argillaceus, B. pascuorum, B. humilis, B. sylvarum) were continuously monitored for several weeks.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Linking bacterial diversity to floral identity in the bumble bee pollen basket

Environmental DNA, 2021
Multitrophic interactions are ubiquitous in nature and form the basis of biodiversity. For example, bumble bees visit flowers to collect pollen, on which a variety of bacteria exist.
