| ecology, life history, and management of tropilaelaps mites. | parasitic mites are the major threat to the western honey bee, apis mellifera l. for much of the world, varroa destructor anderson & trueman single-handedly inflicts unsurmountable problems to a. mellifera beekeeping. however, a. mellifera in asia is also faced with another genus of destructive parasitic mite, tropilaelaps. the life history of these two parasitic mites is very similar, and both have the same food requirements (i.e., hemolymph of developing brood). hence, parasitism by tropilaela ... | 2017 | 28334185 |
| draft genome of the honey bee ectoparasitic mite, tropilaelaps mercedesae, is shaped by the parasitic life history. | the number of managed honey bee colonies has considerably decreased in many developed countries in recent years and ectoparasitic mites are considered as major threats to honey bee colonies and health. however, their general biology remains poorly understood. | 2017 | 28327890 |
| isoform-specific modulation of the chemical sensitivity of conserved trpa1 channel in the major honeybee ectoparasitic mite, tropilaelaps mercedesae. | we identified and characterized the trpa1 channel of tropilaelaps mercedesae (tmtrpa1), one of two major species of honeybee ectoparasitic mite. three tmtrpa1 isoforms with unique n-terminal sequences were activated by heat, and the isoform highly expressed in the mite's front legs, tmtrpa1b, was also activated by 27 plant-derived compounds including electrophiles. this suggests that the heat- and electrophile-dependent gating mechanisms as nocisensitive trpa1 channel are well conserved between ... | 0 | 27307515 |
| deformed wing virus associated with tropilaelaps mercedesae infesting european honey bees (apis mellifera). | mites in the genus tropilaelaps (acari: laelapidae) are ectoparasites of the brood of honey bees (apis spp.). different tropilaelaps subspecies were originally described from apis dorsata, but a host switch occurred to the western honey bee, apis mellifera, for which infestations can rapidly lead to colony death. tropilaelaps is hence considered more dangerous to a. mellifera than the parasitic mite varroa destructor. honey bees are also infected by many different viruses, some of them associate ... | 2009 | 18941909 |
| genetic and morphological variation of bee-parasitic tropilaelaps mites (acari: laelapidae): new and re-defined species. | mites in the genus tropilaelaps are parasites of social honeybees. two species, tropilaelaps clareae and t. koenigerum, have been recorded and their primary hosts are presumed to be the giant honeybees of asia, apis dorsata and a. laboriosa. the most common species, t. clareae, is also an economically important pest of the introduced western honeybee (a. mellifera) throughout asia and is considered an emerging threat to world apiculture. in the studies reported here, genetic (mtdna co-i and nucl ... | 2007 | 17828576 |
| the ectoparasitic mite tropilaelaps mercedesae reduces western honey bee, apismellifera, longevity and emergence weight, and promotes deformed wing virus infections. | historically an ectoparasite of the native giant honey bee apis dorsata, the mite tropilaelaps mercedesae has switched hosts to the introduced western honey bee apis mellifera throughout much of asia. few data regarding lethal and sub-lethal effects of t. mercedesae on a. mellifera exist, despite its similarity to the devastating mite varroa destructor. here we artificially infested worker brood of a. mellifera with t. mercedesae to investigate lethal (longevity) and sub-lethal (emergence weight ... | 2016 | 27126517 |
| bacterial communities associated with the ectoparasitic mites varroa destructor and tropilaelaps mercedesae of the honey bee (apis mellifera). | varroa and tropilaelaps mites have been reported as serious ectoparasites of the honey bee (apis mellifera). in this study, bacterial communities associated with varroa destructor and tropilaelaps mercedesae from northern thailand were determined, using both culture-dependent and culture-independent approaches. adult female mites were collected from apiaries in chiang mai and lampang provinces. culturable bacteria were isolated from individual mites. on average, we observed approximately 1340 an ... | 2017 | 29145627 |
| prevalence, intensity and associated factor analysis of tropilaelaps mercedesae infesting apis mellifera in china. | tropilaelaps mercedesae is a serious ectoparasite of apis mellifera in china. the aim of this study was to investigate the infestation rates and intensity of t. mercedesae in a. mellifera in china, and to explore the relative importance of climate, district, management practices and beekeeper characteristics that are assumed to be associated with the intensity of t. mercedesae. of the 410 participating apiaries, 379 apiaries were included in analyses of seasonal infestation rates and 352 apiarie ... | 2011 | 21590361 |
| chemical and cultural control of tropilaelaps mercedesae mites in honeybee (apis mellifera) colonies in northern thailand. | at least two parasitic mites have moved from asian species of honeybees to infest apis mellifera. of these two, varroa destructor is more widespread globally while tropilaelaps mercedesae has remained largely in asia. tropilaelaps mites are most problematic when a. mellifera is managed outside its native range in contact with asian species of apis. in areas where this occurs, beekeepers of a. mellifera treat aggressively for tropilaelaps and varroa is either outcompeted or is controlled as a res ... | 2017 | 29125881 |
| characterization of the copy number and variants of deformed wing virus (dwv) in the pairs of honey bee pupa and infesting varroa destructor or tropilaelaps mercedesae. | recent honey bee colony losses, particularly during the winter, have been shown to be associated with the presence of both ectoparasitic mites and deformed wing virus (dwv). whilst the role of varroa destructor mites as a viral vector is well established, the role of tropilaelaps mercedesae mites in viral transmission has not been fully investigated. in this study, we tested the effects that v. destructor and t. mercedesae infestation have on fluctuation of the dwv copy number and alteration of ... | 2017 | 28878743 |
| acute bee paralysis virus occurs in the asian honey bee apis cerana and parasitic mite tropilaelaps mercedesae. | viruses, and especially rna viruses, constantly change and adapt to new host species and vectors, posing a potential threat of new and reemerging infectious diseases. honey bee acute bee paralysis virus (abpv) and deformed wing virus (dwv) are two of the most common honey bee viruses found in european honey bees apis mellifera and have been implicated in worldwide varroa-associated bee colony losses. previous studies have shown that dwv has jumped hosts several times in history causing infection ... | 2017 | 29158015 |
| observations on the removal of brood inoculated with tropilaelaps mercedesae (acari: laelapidae) and the mite's reproductive success in apis mellifera colonies. | this study assessed the response of apis mellifera to brood deliberately infested with tropilaelaps mercedesae. the reproductive success of t. mercedesae in mite-inoculated and naturally infested brood was also compared. the presence of t. mercedesae inside brood cells significantly affected brood removal. thai a. mellifera removed 52.6 ± 8.2 % of the brood inoculated with t. mercedesae as compared to 17.2 ± 1.8 and 5.7 ± 1.1 % removal rates for the groups of brood with their cell cappings opene ... | 2014 | 23979656 |
