Bee cups 2.0: P-cups as single-use cages for honey bee (Hymenoptera: Apidae) experiments.

Honey bees and other pollinators face threats from pesticides, imperfect nutrition, and a diverse set of parasites and pathogens. Honey bees are also a research model for development, social behavior, microbiology, and aging. Tackling these questions requires a mix of in-hive and controlled laboratory experiments.

Somy evolution in the honey bee infecting trypanosomatid parasite Lotmaria passim.

Lotmaria passim is a ubiquitous trypanosomatid parasite of honey bees nestled within the medically important subfamily Leishmaniinae. Although this parasite is associated with honey bee colony losses, the original draft genome-which was completed before its differentiation from the closely related Crithidia mellificae-has remained the reference for this species despite lacking improvements from newer methodologies. Here, we report the updated sequencing, assembly, and annotation of the BRL-type (Bee Research Laboratory) strain (ATCC PRA-422) of Lotmaria passim.

Host-driven temperature dependence of Deformed wing virus infection in honey bee pupae.

The temperature dependence of infection reflects changes in performance of parasites and hosts. High temperatures often mitigate infection by favoring heat-tolerant hosts over heat-sensitive parasites. Honey bees exhibit endothermic thermoregulation-rare among insects-that can favor resistance to parasites.

Sunflower-Associated Reductions in Varroa Mite Infestation of Honey Bee Colonies.

Landscapes can affect parasite epidemiology in wild and agricultural animals. Honey bees are threatened by loss of floral resources and by parasites, principally the mite Varroa destructor and the viruses it vectors. Existing mite control relies heavily on chemical treatments that can adversely affect bees.

Multi-tiered analyses of honey bees that resist or succumb to parasitic mites and viruses.

Background: Varroa destructor mites, and the numerous viruses they vector to their honey bee hosts, are among the most serious threats to honey bee populations, causing mortality and morbidity to both the individual honey bee and colony, the negative effects of which convey to the pollination services provided by honey bees worldwide. Here we use a combination of targeted assays and deep RNA sequencing to determine host and microbial changes in resistant and susceptible honey bee lineages. We focus on three study sets.
