A Mathematical Analysis and Evaluation of Varroa mite Control Methods for a Mite-infested Honey bee Colony [PDF]

open access: yesarXiv, 2022
In this paper, we present a mathematical model for the interaction between honey bees and mites. The dynamics of a mite-infested honey bee colony and the evaluation of the commonly used mite-control strategies (traditional, mechanical and chemical) are studied.

Analysis of Energy Consumption in a Precision Beekeeping System [PDF]

open access: yes, 2020
Honey bees have been domesticated by humans for several thousand years and mainly provide honey and pollination, which is fundamental for plant reproduction. Nowadays, the work of beekeepers is constrained by external factors that stress their production (parasites and pesticides among others). Taking care of large numbers of beehives is time-consuming,
