From consumption to excretion: Lithium concentrations in honey bees (Apis mellifera) after lithium chloride application and time-dependent effects on Varroa destructor.

Background: Owing to its systemic mode-of-action and ease of application, lithium chloride (LiCl) is an ideal varroacide for the control of Varroa destructor infestations in honey bee colonies. To better understand how LiCl functions within a colony, we screened different parts of honey bee anatomy for lithium accumulation. We wanted to elucidate the time-dependent effects of LiCl on V.

Mite non-reproduction is not a consequence of the brood removal behavior of varroa sensitive hygiene honey bee colonies ().

A sustainable solution to the global threat of the mite is the selection of varroa-resistant honey bee () colonies. Both "mite non-reproduction" (MNR) and "varroa sensitive hygiene" (VSH) appear to be promising selection traits for achieving the goal of a resistant honey bee. MNR describes colonies that have a high number of non-reproductive mites (no offspring, no males, or delayed development of mite offspring).

Sustained success of a Caprini postoperative venous thromboembolism prevention protocol over one decade.

Background: The objective of this study was to review the long-term efficacy of a post-operative venous thromboembolism (VTE) prevention program at our institution.

Methods: We performed a review of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data at our hospital from January 2008-December 2022. The primary outcome was risk-adjusted VTE events.

Lithium chloride treatments in free flying honey bee colonies: efficacy, brood survival, and within-colony distribution.

The efficacy of various lithium chloride (LiCl) applications in eradicating the parasitic mite Varroa destructor in honey bee colonies was investigated, with a specific focus on its impact on brood development. In broodless colonies (3 weeks post queen caging), the highest efficacy of 98% was achieved with a 9-day treatment of 2.5 kg of candy spiked with 50 mM LiCl.

Defined exposure of honey bee colonies to simulated radiofrequency electromagnetic fields (RF-EMF): Negative effects on the homing ability, but not on brood development or longevity.

Urbanization and the increasing use of wireless technologies lead to higher emission rates of radiofrequency electromagnetic fields (RF-EMF) in populated areas. This anthropogenic electromagnetic radiation is a form of environmental pollution and a potential stressor on bees or other flying insects. Cities often have a high density of wireless devices operating on microwave frequencies, which generate electromagnetic frequencies e.
