Dermanyssus gallinae is considered to be the most economically significant ectoparasite to affect egg-laying poultry in Europe. This mite can also act as a vector for a number of pathogens. The array of bacteria associated with D. gallinae mites could provide insight into the biology and population dynamics of arthropods, but at the present time little information is available. To understand th...

Dermanyssus gallinae is the most economically important ectoparasite of laying hens in Europe. Control of D. gallinae is already hampered by issues of pesticide resistance and product withdrawal and, with the prohibition of conventional cages in 2012 and the resulting switch to more structurally complex housing which favours red mite, the importance of managing this pest will increase. Integrat...

BACKGROUND Blood sucking mites are important avian ectoparasites which being found on bird species worldwide. Their presence are problematic for the producers either through potential direct effects on weight gain, egg production, sperm production in roosters or as nuisance pests on worker handle hens and eggs. The aim of this study was pointing out of the status of haematophagus mites. METHO...

Poultry red mite or Dermanyssus gallinae (De Geer, 1778) is the most significant poultry ectoparasite with regards to health and economy. It a widely accepted opinion that D. can only be suppressed, current annual expenditure of 60 eurocents per layer. However, research indicates controlled in other ways eradicated from production facilities farms, subsequent reinfestation prevented by implemen...

Tarım ve hayvancılık açısından risk oluşturan zararlılar, doğrudan ya da dolaylı olarak ekonomik kayıplara neden olmaktadır. Bununla birlikte bir kısım zararlı ise başta insan olmak üzere canlı sağlığını tehdit eden çeşitli hastalıkların vektörüdür. Dolayısıyla zararlılar ile mücadelede kimyasal yöntemlere alternatif stratejilerin geliştirilmesinde maternal kalıtılan üreme manipülatörü endosimb...

Although artificial feeding models for the poultry red mite (Dermanyssus gallinae) most frequently use biological membranes consisting of day-old chick skin, there are ethical considerations associated with the use of skin. The few studies reported in the literature that have investigated the use of synthetic membranes to feed D. gallinae in vitro have reported limited success. The current stud...

this study was aimed to determine abundance and body distribution of prm in laying hens of arak. a total of 1400 laying hens were randomly examined from january to june 2008. of those, 26 (92.86%) layer farms were found to be infested with dermanyssus gallinae (39.3%). there was significant association between prevalence and climatic conditions of the region. the most common predilection site o...

Control of the poultry red mite Dermanyssus gallinae is a challenge for organic as well as conventional egg producers. In organic agriculture, control should be attempted by mechanically acting substances (e.g. oils or diatomaceous earth), before acaricides are applied. Diatomaceous earth (DE) without acaricides was at least as effective as DE supplemented with pyrethrum or essential oils and a...
