- Tropilaelaps infestation of honey bees
OverviewTop of page
This datasheet is about Tropilaelaps infestation of honey bees as defined by the OIE, i.e. an infestation of honey bees of the genus Apis caused by mites of the genus Tropilaelaps, including T. clareae, T. koenigerum, T. thaii and T. mercedesae (OIE, 2013b). The mites are ectoparasites of honey bee brood, and cannot survive for periods of more than a few days away from such brood (Anderson and Roberts, 2013). They kill bee larvae or impede their development by depriving them of nutrition (Defra, 2005; FERA, 2013), and can also spread pathogenic viruses (OIE, 2013b).
T. clareae was previously thought to be ubiquitous in Asia, but has now been found to be two species: following a genetic and morphological study, Anderson and Morgan (2007) redefined T. clareae as containing haplotypes that parasitise native Apis dorsata breviligula and introduced A. mellifera in the Philippines, and native A.dorsata binghami on Sulawesi Island in Indonesia. The new species T. mercedesae (previously mistaken for T. clareae) was defined as including haplotypes that parasitise native A. dorsata dorsata and introduced A. mellifera in mainland Asia and Indonesia (except Sulawesi), as does the already known species T. koenigerum. T. mercedesae and another new species, T. thaii, were also recorded as attacking A. laboriosa [A. dorsata laboriosa] in mountainous Himalayan regions.
Tropilaelaps infestation causes serious damage to apiculture throughout Asia, and although it has so far not spread much beyond Asia, it is considered serious enough, and likely enough to spread, to be a significant emerging threat to world apiculture (Anderson and Roberts, 2013).
Hosts/Species AffectedTop of page
T. clareae was first discovered on Apis mellifera in the Philippines (Delfinado and Baker, 1961), but the primary hosts of Tropilaelaps mites are presumed to be the ‘giant’ honeybees of Asia: Apis dorsata and A. laboriosa [A. dorsata laboriosa] (Anderson and Morgan, 2007).
T. clareae and T. mercedesaebetween them (formerly believed to be the single species T. clareae) are economically important pests of the introduced Western honey bee, Apis mellifera, throughout Asia (Anderson and Morgan (2007). Other host species include A. cerana and A. florea (Bailey and Ball, 1991; Schmid-Hempel, 1998), although according to Anderson and Roberts (2013), Tropilaelaps mites are only very occasionally found in colonies of these species and have only ever once been recorded as producing offspring there.
A. dorsata has been described at the ‘primary host’ of T. clareae (Laigo and Morse, 1968), but Tropilaelaps mites were able to switch to the western honeybee, A. mellifera (Delfinado and Baker, 1961; Anderson and Morgan, 2007) where infestations rapidly lead to colony death (Forsgren et al., 2008). This has led to the consideration that Tropilaelaps is more dangerous to A. mellifera than Varroa destructor (Forsgren et al., 2008).
T. mercedesae may infest as much as 90% of the brood in A. mellifera colonies, but much lower levels (3-6%) are reported in A. dorsata colonies, and A. dorsata and A. cerana workers show greater resistance than those of A. mellifera (Anderson and Roberts, 2013).
DistributionTop of page
T. clareae was first discovered on Apis mellifera in the Philippines (Delfinado and Baker, 1961), but Tropilaelaps are found throughout much of Asia (Anderson and Morgan, 2007) and infest a range of honeybee species (Bailey and Ball, 1991; Schmid-Hempel, 1998). Apart from a doubtful record from Kenya in the early 1990s, Tropilaelaps mites have not yet been found outside Asia and bordering areas (Anderson and Roberts, 2013). Glinski and Kostro (2001) mention T. clareae as being a problem in South Africa, but no other evidence of this is apparent.

DiagnosisTop of page
Early signs of infestation usually go unnoticed, but the growth in the mite population is rapid and leads to high hive mortality (OIE, 2013b).
Apis mellifera colonies show similar damage whether infested with Tropilaelaps or Varroa destructor. Brood mortality and a reduced adult life span of any bee that has survived the parasitized brood stage are indications of mite infestation. If a bee is infested during development, and survives to adulthood, it may be physically or physiologically damaged as an adult. Damage may include: shorter lifespan; lower body weight; and shrunken and deformed wings and legs. Deformed bees may be observed crawling at the hive entrance (Defra, 2005).
Other signs of infestation include irregular and poor brood patterns with patches of neglected brood and perforated cappings. When infestation is severe, losses of up to 50% of brood may be observed and there may be a smell of decaying pupal and larval remains (Defra, 2005).
Methods used in the detection of Varroa can be used to monitor for Tropilaelaps: regular collection and examination of floor debris and hive inserts; examination of bees and brood; and the use of a proprietary acaricide. It is relatively easy to distinguish Tropilaelaps from Varroa (especially with the aid of a magnifying glass): Tropilaelaps are smaller, elongated and fast-moving (Defra, 2005).
Anderson and Roberts (2013) provide information on how to identify mites by morphological examination (identification to the species level by this method can be difficult) and by molecular methods.
Disease CourseTop of page
EpidemiologyTop of page
Tropilaelaps mites have similar lifecycles and modes of parasitism to Varroa destructor, but with a shorter life cycle enabling populations to expand more quickly (Defra, 2005). The following description of the lifecycle is based on information provided in Defra's and FERA's’s factsheets on Tropilaelaps mites, which should be consulted for further information (Defra, 2005; FERA, 2013). The adults enter bee cells containing larvae, and reproduction takes place within sealed brood cells. Although the mites show a preference for reproducing in drone cells, they can also reproduce in worker cells. Females lay 3-4 eggs on mature bee larvae, 48 hours after capping, approximately 1 day apart.
After 12 hours, the eggs hatch and develop into protonymphs and deutonymphs before reaching adulthood. Hatched male and female mites feed on developing bee haemolymph and this deprives the bee of essential nourishment.
Egg laying to adulthood usually takes approximately 6 days (although different studies show considerable variation – Anderson and Roberts, 2013). Once emerged the adult mites and the original invading female mite exit the cell to search for new hosts. A single cell has been observed to hold 14 adult mites and 10 nymphal stages.
In contrast to Varroa, the mouthparts of Tropilaelaps cannot pierce the body wall of adult bees, so they depend on bee brood for food and cannot survive long in its absence.
Tropilaelaps mites are mobile and can easily move between bees and within a hive; however, they require adult bees to move between colonies and are therefore spread over longer distances via the natural processes of drifting, robbing and swarming (bees abandoning a severely infested hive may help to spread the mites). They can also be spread on equipment or via the usual practices of beekeepers. The main and most rapid means of spread is the movement of infested Apis mellifera colonies to new areas by beekeepers (Defra, 2005; FERA, 2013).
ImpactTop of page
Honeybee mites are major limiting factors in beekeeping, and Tropilaelaps can causes 50-100% loss of bee colonies (Hosamani et al., 2006). High infestations of A. mellifera brood often result in adult bees with deformed wings and reduced body weight; untreated infestations rapidly increase to high levels and invariably lead to the death of entire colonies (Anderson and Roberts, 2013). Honey bees are important to the agricultural and horticultural sectors as pollinators, so any disease causing decline in bee populations will have a significant impact on their role in these industries.
Dainat et al. (2009) investigated T. mercedesae as a vector of honeybee viruses. They sampled worker bees and T. mercedesae mites from three A. mellifera colonies exhibiting symptoms of deformed wing virus (DWV). They analysed samples for DWV, Black queen cell virus (BQCV), Sacbrood virus (SBV), Kashmir bee virus (KBV), Acute bee paralysis virus (ABPV) and Chronic bee paralysis virus (CBPV). Only DWV was found, but evidence indicated virus replication. The authors concluded that T. mercedesae may be a biological vector of DWV, indicating a route for virus spread in A. mellifera.
Bee decline caused by Tropilaelaps and other problems will have a significantly negative affect on pollination by bees. The value of pollination is estimated to exceed the value of products from beehives many-fold (Delaplane and Mayer, 2000).
The effect of Tropilaelaps infestations on honeybee health will also have a significant impact on the livelihood of beekeepers who rely on their industry for income.
Impact on habitats
Bee decline caused by Tropilaelaps and other problems will have a significant negative affect on pollination by bees in habitats where such pollination may be important.
Impact on biodiversity
Any decline in native bees due to infestation by Tropilaelaps would have a negative effect on bee biodiversity (Cuthbertson and Brown, 2009) (although so far the main negative impacts have been on A. mellifera in areas to which it has been introduced).
Disease TreatmentTop of page
Tropilaelaps mites can be killed by acaricides and the aim of control is to keep populations below economic threshold levels. These acaricides can be applied in feed, directly to adult bees, as fumigants, in contact strips or by evaporation (Defra, 2005). The efficacy of various acaricides, including formic acid, sulfur, fluvalinate and amitraz, has been investigated in a number of studies (e.g. Sharma et al., 2003; Arun et al., 2003; Rashid Mahmood et al., 2011; Yu et al., 2011; FERA, 2013).
Yu et al. (2011) investigated the effect of sublimed sulfur and acaricides on T. clareae and Varroa destructor. They reported that mites could be eliminated on combs or during the pupal stage, but not on adult bees.
The controlling effects of thymol and formic acid were investigated in a study at the Honeybee Research Institute in Islamabad, Pakistan (Rashid Mahmood et al., 2011). The results showed that formic acid killed a significantly higher number of mites compared to treatments with thymol. Further, the total honey production harvested from colonies treated with different acaricides remained the same.
Hosamani et al. (2007) studied various botanicals against T. clareae in Apis mellifera colonies. Garlic leaves, liquorice leaves and turmeric rhizomes were investigated. Garlic extract appeared to be most effective and caused 72% and 63% of dead mites in hive debris of brood frames, with and without bees, respectively.
Prevention and ControlTop of page
FERA (2013) recommends that beekeepers should monitor their hives for Tropilaelaps as part of their management routine, which is particularly important if hives are in high risk areas (i.e. around ports and container freight terminals).
One of the main ways in which Tropilaelaps is spread is by beekeepers; therefore good husbandry practices will help to prevent further spread. Trapping mites in brood combs so that they can be removed and destroyed is effective (Defra, 2005; FERA, 2013).
Tropilaelaps cannot survive outside sealed brood for more than a few days, or feed on adults, so creating breaks in the brood, for example by caging the queen, is an effective means of exploiting this aspect of the mite lifecycle by causing a break in it (Defra, 2005; FERA, 2013).
OIE’s Terrestrial Animal Health Code (OIE, 2013b) provides information on how to avoid the spread of Tropilaelaps through trade in bees, beekeeping equipment or bee products.
