“…personal observation). Other studies have shown that winter mortality rates in colonies with tracheal mites are generally higher in cold climates (Eischen, 1987;Otis and Scott-Dupree, 1992). Honeybees in a colony with a moderate infestation will have reduced capability to use their flight muscles to generate thoracic heat due to mites and associated debris blocking the prothoracic tracheae (Komeili and Ambrose, 1991).…”

-An assessment was made of tracheal mite susceptibility in honeybees pupated at a low temperature. Using a laboratory bioassay, an experiment was conducted to compare the performance of newly-emerged (callow) bees raised at 30 ºC with those raised at the more normal brood temperature of 34 ºC. The reduced temperature caused a delay of over 5 days in the emergence of the bees from the brood cells. The callow bees raised at 30 ºC had over twice the mite prevalence level. The fecundity of the mites in the tracheae was similar for both temperature conditions. Increased susceptibility to tracheal mites resulting from reduced brood temperature may help to explain the mortality, in the temperature-stressed late winter/early spring period, of colonies with a moderate mite infestation in autumn. Further work is required to identify the mechanism responsible for this increased susceptibility.Apis mellifera / Acarapis woodi / tracheal mite / brood temperature / susceptibility to infestation

“…For example, a lightly infested beehive shows low honey production and low pollination capacity (Eischen, 1987;Eischen et al, 1989;Otis and Scott-Dupree, 1992). A heavy load of A. woodi results in colony loss during winter (Eischen, 1987;Eischen et al, 1989;McMullan and Brown, 2009). Such damage is derived from injuries to individual bees, including nutritional loss, damage to tracheal Fig.…”

Effects of tracheal mite infestation on Japanese honey bee, <i>Apis cerana japonica</i>

The honey bee tracheal mite, Acarapis woodi (Acari: Tarsonemidae), is an endoparasite of honey bees. The mites feed on bee hemolymph in the tracheas of adult bees. Mite infestations cause serious damage to bee colonies. The distribution of these mites is now worldwide, from Europe to South and North America. The first recorded A. woodi infestation in the Japanese native honey bee, Apis cerana japonica, occurred in 2010. In a previous study, to determine the distribution of A. woodi in Japan, we sampled more than 350 colonies of A. cerana japonica. We found mite infestation from central to eastern Japan. On the other hand, Apis mellifera in Japan has not suffered serious mite damage. Here, to determine the effects of mite infestation on Japanese native honey bees, we investigated seasonal prevalence, mite load in the tracheal tube, and the relationship between mite prevalence and K-wing (disjointed wings). Similar to European honey bees, Japanese honey bees had a high prevalence of mite infestation in winter and a low prevalence in summer. The average mite load was about 21 or 22 mites (all stages) per trachea when all bees were infested by tracheal mites (100% mite prevalence). This mite load did not differ from that in A. mellifera. The K-wing rate was positively correlated with mite prevalence. Further comparative investigations focusing on the mechanisms of infestation will be needed to elucidate the differences in mite susceptibility between Japanese and European honey bees.

“…A. woodi sucks the haemolymph from honeybees (Pettis and Wilson 1996) and causes damage to both individuals (Bailey and Lee 1959;Eischen 1987;Liu 1990;Komeili and Ambrose 1991) and colonies (Eischen et al 1989;Bailey and Ball 1991;Otis and Scottdupree 1992). The most critical damage inflicted by tracheal mites on the honeybee colonies is colony death during winter (Clark 1991;McMullan and Brown 2009;Maeda 2016).…”

-This study evaluated the damage caused by the tracheal mite Acarapis woodi to colonies of the Japanese honeybee Apis cerana japonica , by investigating mite prevalence and colony death of the honeybees during winter. Honeybees of 114 colonies were sampled from October to December to detect mite prevalence. The colony death was monitored up to the end of April. The observed mortality due to mite infestation was compared with data from two previous studies about European honeybees. Under normal conditions in the absence of mites, 21 % of intact colonies died during the winter season. However, once the honeybee colonies were infested with A. woodi , the overwinter mortality was drastically increased. The mortality of Japanese honeybee colonies infested with the tracheal mites was higher than that reported historically in European honeybee colonies infested with the mites. Investigation of colony mortality at the apiary level showed that mortality was significantly higher in miteinfested than non-infested apiaries, but there were no significant differences related to the estimated winter air temperature. These results suggest that tracheal mite infestation seriously increases the overwinter mortality of Japanese honeybees.Asian honeybee / tracheal mite / colony death / overwinter mortality
