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.

Effect of Varroa destructor, Wounding and Varroa Homogenate on Gene Expression in Brood and Adult Honey Bees. [PDF]

PLoS ONE, 2017
Honey bee (Apis mellifera) gene expression related to immunity for hymenoptaecin (AmHym) and defensin-1 (AmDef-1), longevity for vitellogenin (AmVit2) and stem cell proliferation for poly U binding factor 68 kDa (AmPuf68) was compared following Varroa ...

Oldest Varroa tolerant honey bee population provides insight into the origins of the global decline of honey bees [PDF]

, 2017
The ecto-parasitic mite Varroa destructor has transformed the previously inconsequential Deformed Wing Virus (DWV) into the most important honey bee viral pathogen responsible for the death of millions of colonies worldwide.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Honey bee populations surviving Varroa destructor parasitism in Latin America and their mechanisms of resistance

Frontiers in Ecology and Evolution
The honey bee (Apis mellifera) parasitic mite, Varroa destructor, is considered one of the main causes of colony losses in European honey bee (EHB) populations around the world.

Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Evaluating Electric Harps and Muzzles to Mitigate the Impact of Vespa velutina nigrithorax at Beehives

Journal of Applied Entomology, Volume 150, Issue 3, Page 364-375, April 2026.
ABSTRACT The Asian hornet (Vespa velutina nigrithorax) poses a significant threat to the beekeeping industry. Using an experimental apiary of 36 hives, we simultaneously evaluated the effectiveness of two mitigation measures—muzzles and electric harps—in reducing the impact of Asian hornets on honey bee colonies.

Environmental DNA Methods for Detection of Varroa destructor in Honey Bee (Apis mellifera) Hives

Environmental DNA
The parasitic mite, Varroa destructor, is a worldwide problem for honey bees (Apis mellifera). The recent spread of this pest to Australia, which was one of the few varroa‐free honey bee populations remaining, highlights the importance of effective ...
