Economic Damages

Technological solutions and environmental conditions have a significant impact on infestation intensity and the problems around D. gallinae control. Changes in keeping laying hens in EU, in terms of D. gallinae influence, have not led to the welfare of the layers. On the contrary, they have contributed to the spreading of disease, have worsened conditions for control and accentuated harmful consequences. Apart from the poultry, these changes have also had a negative impact on the welfare of humans, through a toxicological and zootonic risk, and economic damages. Conventional cages so far provide the most appropriate environment for D. gallinae control. Opportunities for improving, even solving the problem of D. gallinae control in egg production do exist, however they require a changing the entire approach hitherto.

The Impact

Abstract Poultry red mite (PRM), Dermanyssus gallinae, causes egg drop production, anemia and can be a vector in transmitting diseases. The PRM control mainly focuses on usage of the conventional chemical biocides. The objective of this study was to analyze the farmers’ perception regarding the impact, management and control of PRM in Macedonian layer farms. The data were collected with direct on-site visits using a unified questionnaire. In total, 29 poultry farms (28% of farms in the country), all with conventional cages, were part of this study. The data were analyzed by descriptive statistics, inferential statistics and Naïve Bayes Classifier technique. In 30% of the poultry farms the farmers had observed that the flock was infested with PRM. In total, 32 different treatments against PRM were reported from the farmers, and three of them were non-biocide treatments. The most used biocides (17% of the farms) were crude oil, Formalin, Neopitroid® and disinfectants. The highest agreement regarding biocides application among the farms (38%) was before the production starts. Most of the farmers applied biocides routinely, before the infestation is evident (75%). The median costs for PRM treatment were 175€ per flock, higher in the infested farms 493±677€ compared to non - infested 100±71€, p<0.05. None of the Macedonian farmers included in the study was using monitoring method for PRM infestation, contributing to poor data records. This study highlights the need of developing unified strategy for PRM control included in the Integrated Pest Management in poultry layer farms.

And Control

Dermanyssus gallinae (De Geer, 1778), poultry red mite or chicken mite, is haematophagous poultry ectoparasite. In poultry flocks small populations of chicken mite usually remain undetected. In order to supplement existing diagnostics we have investigated the method for its early detection. Investigation was carried out on 13 flocks, during two-year period, throughout Serbia and Montenegro. We have established that method for early detection of chicken mite can: improve the efficiency of existing diagnostic methods, that it is simple and reduces the period when parasites are hidden since it enables detection of small number of parasites before the population becomes visible. We recommend it to poultry farmers for regular control of the flock and control of the new flock, to veterinarians in poultry production as supplement to diagnostic methods: when suspecting the presence of Dermanyssosis in order to achieve early differential diagnostics, sampling of small number of chicken mite, monitoring the movement of the population and effect of the treatment, coming to conclusion regarding the effect of the disease control and as element of the forensic evaluation method. .

Worldwide Distribution

The poultry red mite (PRM), Dermanyssus gallinae, is a hematophagous ectoparasite of birds with worldwide distribution that causes economic losses in the egg-production sector of the poultry industry. Traditional control methods, mainly based on acaricides, have been only partially successful, and new vaccine-based interventions are required for the control of PRM. Vaccination with insect Akirin (AKR) and its homolog in ticks, Subolesin (SUB), have shown protective efficacy for the control of ectoparasite infestations and pathogen infection/transmission. The aim of this study was the identification of the akr gene from D. gallinae (Deg-akr), the production of the recombinant Deg-AKR protein, and evaluation of its efficacy as a vaccine candidate for the control of PRM. The anti-Deg-AKR serum IgY antibodies in hen sera and egg yolk were higher in vaccinated than control animals throughout the experiment. The results demonstrated the efficacy of the vaccination with Deg-AKR for the control of PRM by reducing mite oviposition by 42% following feeding on vaccinated hens. A negative correlation between the levels of serum anti-Deg-AKR IgY and mite oviposition was obtained. These results support Deg-AKR as a candidate protective antigen for the control of PRM population growth.

Synthetic Pesticides

Conventional pest management (the use of synthetic pesticides) is being increasingly hampered by issues of pest resistance, tighter legislation and greater consumer demand for food stuffs produced in an environmentally friendly manner. A growing body of research suggests that essential oils may be of use as an alternative to synthetic products in managing the poultry red mite (Dermanyssus gallinae), a serious pest of egg production systems for laying hens (Kim et al., 2004). It is necessary to ensure that any essential oil recommended as an acaricide against this pest does not taint the eggs produced from hens in poultry units in which the oil would be deployed. The aim of the current study was to test the hypotheses that thyme and pennyroyal essential oils, having been found to be effective as acaricides for D. gallinae in preceding work, would have no effect on the occurrence of taint in hens’ eggs.

Red mite (Dermanyssus gallinae; De Geer, 1778) is currently the most economically deleterious ectoparasite of layer hens in several countries (Chauve, 1998). D. gallinae is an obligatory haematophagous ectoparasite of both domestic and wild birds (Bruneau et al., 2001), only found on the host during darkness when obtaining a blood meal. The remaining part of its lifecycle is spent concealed deep in the house substructure, in cracks and crevices, with control typically implemented via chemical spraying. Mite exposure in laying hens generally results in irritation, restlessness, anaemia, and occasionally death and may subsequently lead to decreased egg production, poor shell integrity, blood staining and egg size reductions (Chauve, 1998; Cosoroaba, 2001). Natural exposure to mite-antigens during feeding activates humoral immunity of the fowl, in the form of immunoglobulin production. However, the magnitude of this serological response over a prolonged infestation period and at different mite population levels is unclear. Therefore the aim of this study was to determine the levels of anti-mite immunoglobulin present in egg yolks of laying hens in flocks infested with differing population levels of red mite over a period of 16 weeks.
