Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Pest Management Science, EarlyView.Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Pest Management Science, EarlyView.Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

Influence of nano-polystyrene on cyfluthrin toxicity in honeybee Apis cerana cerana Fabricius
Ecotoxicology and Environmental SafetyPlastics and pesticides are commonly used and often coexist in the environment. As pollinating insects, honeybees are simultaneously exposed to both these toxins. However, there has been no study on the toxic effects of nano-polystyrene plastics (nanoPS)

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‐

Why honey is effective as a medicine. 2. The scientific explanation of its effects [PDF]
, 2001 The effectiveness of honey as a therapeutic agent has been unequivocally demonstrated in the literature reviewed in Part 1 of this article published in 1999, but the biochemical explanation of these effects is more hypothetical.

Sacbrood virus of the larval honey bee (Apis mellifera linnaeus) [PDF]
, 1964 Extracts of honey bee larvae suffering from sacbrood contained many isometric particles that were about 28 mμ in diameter. When the extracts or purified preparations of the particles were put into the food of healthy larvae, these developed sacbrood. The

Honey Bee and Bumble Bee Antiviral Defense [PDF]
Viruses, 2018 Bees are important plant pollinators in both natural and agricultural ecosystems. Managed and wild bees have experienced high average annual colony losses, population declines, and local extinctions in many geographic regions. Multiple factors, including virus infections, impact bee health and longevity.
