“…Anyway, few data are available on the infestation rate in backyard poultry farms. The red mite is almost ubiquitous and challenging to eradicate in rural or in ornamental breeding [15] due to the multitude of farmed species present, potential contacts with wild hosts, and un modern breeding structures, which provide more hiding places for mites. The presence and distribution of D. gallinae are not only greatly influenced by the conditions of the rearing environment but also by the efficiency of products and methods used for its control.…”

The poultry red mite Dermanyssus gallinae is the most important blood-sucking ectoparasite in egg-laying hen facilities. The aim of this study was to evaluate the in vitro acaricidal activity of different concentration of authorized (phoxim, ByeMite®, 500 mg/mL) and unauthorized (fipronil, Frontline® 250 mg/100 mL spray) molecules on 14 field isolates of D. gallinae collected from different ornamental poultry farms from different Italian regions. The sensitivity test was performed by contact exposure to four concentrations of each insecticide diluted at 1:5 (10,000-2000-400-80 ppm for phoxim, 500-100-20-4 ppm for fipronil) on a filter paper. The effectiveness of the treatment was significantly (p < 0.0001) associated with the dose of the pesticide used. Considering the mean lethality, phoxim has greater efficacy compared to fipronil (p < 0.001). A great variability of lethality rate was observed with the increase in fipronil dilution; conversely, for phoxim, some outliers were observed, particularly in one farm, suggesting the hypothesis that a certain degree of resistance in the mite population could occur possibly as a consequence of the continual contact with the molecule. This underlines the importance of the use of licensed products administered at correct dosages and the need for alternative molecules to avoid the onset of drug resistance phenomena.

“…Further information on red mite and its control in backyard flocks has been given by Kenyon 2 . Most of the mortality seen in adult chickens in small flocks is sporadic, but unexpected or increased mortality affecting several birds should always prompt consideration of whether notifiable disease may be involved, especially if accompanied by other suggestive clinical signs 3 …”

There is currently a very low risk of incursion of CSF virus to the UK, and this is being kept under review. BluetongueIn December, in Europe, there were 10 outbreaks of bluetongue virus (BTV) in Portugal.Currently the risk of BTV incursion to the UK remains low. Animals travelling to or from BTV-affected areas of Europe, and back to the UK, must be vaccinated against both BTV-8 and BTV-4. More information on the BTV situation in Europe can be found at https://bit.ly/34gzrhE. Further advice on how to spot and report BTV can be found at https:// bit.ly/3wy4scZFoot-and-mouth disease In December, the following FMD outbreaks were reported: serotype O in Jordan (three), Palestine (two) and Russia (one); and serotype unavailable in Palestine (one).

“…Ectoparasites, including mites and lice, are also common causes of illthrift. The blood‐sucking effects of red mite ( Dermanyssus gallinae ) and less commonly northern fowl mite ( Ornithonyssus sylviarum ) lead to anaemia and sometimes death, and these parasites require specific control measures 6 …”
