| occurrence and genetic analysis of picorna-like viruses infecting worker bees of apis mellifera l. populations in devon, south west england. | viruses of the european honeybee, apis mellifera l. are known to reside at low levels in colonies, typically showing no apparent signs of infection. using reverse transcription-pcr (rt-pcr), 23 apiaries in devon were screened for the presence of 6 honeybee viruses, with positive colonies being analysed for viral genetic diversity. ninety-seven percent of the colonies were positive for deformed wing virus (dwv), 29% were positive for acute bee paralysis virus (abpv) and 1.4% were positive for bot ... | 2008 | 18359042 |
| the occurrence of melissococcus plutonius in healthy colonies of apis mellifera and the efficacy of european foulbrood control measures. | european foulbrood (efb) persists in england and wales despite current treatment methods, all of which include feeding honey bee colonies with the antibiotic oxytetracycline (otc). a large-scale field experiment was conducted to monitor a husbandry-based method, using comb replacement (known as shook swarm), as a drug free efb control option. the understanding of efb epidemiology is limited, with little information on the presence of melissococcus plutonius in disease free colonies. additional s ... | 2010 | 20600088 |
| molecular epidemiology and population structure of the honey bee brood pathogen melissococcus plutonius. | melissococcus plutonius is the causative agent of european foulbrood (efb), which is a serious brood disease of the european honey bee (apis mellifera). efb remains a threat because of a poor understanding of disease epidemiology. we used a recently published multi-locus sequence typing method to characterise 206 m. plutonius isolates recovered from outbreaks in england and wales over the course of 2 years. we detected 15 different sequence types (sts), which were resolved by eburst and phylogen ... | 2014 | 24599072 |
| clustering, persistence and control of a pollinator brood disease: epidemiology of american foulbrood. | american foulbrood (afb), caused by paenibacillus larvae, is the most damaging bacterial brood disease of the honeybee (apis mellifera), causing colony deaths on all continents where honeybees are managed. afb has been a persistent problem in the uk for over 70 years, with a fluctuating number of cases discovered annually. once diseased colonies are identified, they are destroyed to reduce pathogen spread. we investigated the pattern of afb cases recorded over the period 1994 to 2012 using spati ... | 2014 | 24119163 |
| neonicotinoid concentrations in uk honey from 2013. | concentrations of the neonicotinoid insecticides clothianidin, thiamethoxam and imidacloprid were determined in honey collected in spring 2013 from a variety of locations in england. the honey was produced before the moratorium in the eu on the use of neonicotinoids in pollinator-attractive crops became effective. | 2016 | 26750092 |
| neonicotinoid concentrations in arable soils after seed treatment applications in preceding years. | concentrations of the neonicotinoid insecticides clothianidin, thiamethoxam and imidacloprid were determined in arable soils from a variety of locations in england. | 2014 | 24888990 |
