Hygienic Behavior of Apis mellifera and Its Relationship with Varroa destructor Infestation and Honey Production in the Central Highlands of Ecuador

Abstract: The aim of this research was to analyze the relationship among hygienic behavior (HB), Varroa destructor infestation, and honey production in the central highlands of Ecuador. Overall, 75 honey bee colonies were evaluated before, during, and after production at three altitude levels (2600–2800, 2801–3000, and >3000 m.a.s.l.). The hygienic behavior percentage of the colonies was determined by the pin-killing method, and the colonies were classified into three groups: high HB (>85%), mid HB (60.1–85%), and… Show more

“…According to research in southwestern Ethiopia ( Shegaw et al, 2022 ) and the Tigray region ( Haftom et al, 2019 ), infection levels were higher during the wet season than during the dry season. Lower temperatures and higher humidity during the wet season that influenced the hygienic behavior of honey bees that is inversely correlated with the level of infestation may be the cause of the higher level of infection during this season ( Masaquiza et al, 2021 ). Similarly, the level of infection was also strongly correlated with the strength of the colony and the agroecology of the area where the colony was located, both in adult bees and in brood cells.…”

“…Being such highly polygenic, this behavior would be expected to be susceptible to external infl uences, but the investigations are scarce and the fi ndings non-consistent. Bigio et al [56] reported no great infl uence of environmental conditions on hygienic behavior, but a reverse relationship was reported between hygienic behavior expression and altitude [57], seasonal and environmental variations [58]. Hygienic behavior was not correlated with the colony strength [59] and was not affected by Nosema ceranae infection [60].…”
