Sažetak
The poultry red mite Dermanyssus gallinae is a blood-feeding ectoparasite which poses a significant threat to the laying-hen industry worldwide, particularly in Europe ; it adversely affects production as well as hen health and welfare, both directly and also through its role as a disease vector. The economic importance of this pest has increased greatly for the poultry industry, and D. gallinae has emerged as an occupational hazard for poultry workers, since it commonly attacks humans. Although poultry production has moved from conventional cage systems towards a more welfare-oriented breeding system in many European countries, D. gallinae is becoming increasingly widespread, and its control is likely to become more difficult. The poultry industry still relies widely on chemical acaricides for control of red mite D. gallinae, but only a limited number of products registered and licensed for use against the pest is available on the market in the European Union. In addition to a product based on an old compound (phoxim), there is only a biopesticide, spinosad-based, and this is not on sale in all European countries. This means that farmers throughout Europe continue to tackle D. gallinae infestations using synthetic pesticides registered for use in agriculture or on other animals – both livestock and companion animals – which have not been approved specifically (amitraz, various pyrethroids) or have been banned for years by the EU (propoxur, dichlorvos and carbaryl). More recently, ‘miracle’ products containing unknown chemical molecules have begun to appear on the unofficial/illegal market and are being used by farmers. The lack of regulations related to products, and the use of unregulated, ‘home-made’ compounds for treating red mites have serious consequences for the poultry industry. The situation poses a threat to animal and human health because it favours the widely-attested development of acaricide-resistant D. gallinae populations, consequently leading to the reduced effectiveness of the chemical. If treatment is not effective and lasting, farmers tend to increase the dosage or to treat their animals more often. This exacerbates the appearance of resistant mites, and can favour the accumulation of chemical residues in the organs and tissues of poultry, as has already been registered in specific cases of chemical misuse/abuse in some European countries. Although some alternative control measures are beginning to penetrate the market (but most remain at the pre-commercial stage), acaricide resistance and the current lack of regulations, monitoring and hen welfare legislation will make future management of D. gallinae even more difficult in many EU countries. These issues are of great concern, and COST Action FA1404 on “Improving current understanding and research for sustainable control of the poultry red mite Dermanyssus gallinae (COREMI)”, is making every effort to promote research on novel acaricides and biological control, and to underline the pressing need for stricter surveillance/monitoring by EU Health Authorities who are urged to tackle the problem and to establish specific regulations. Numerous groups from research, public health, industry and poultry organizations throughout Europe have an interest in D. gallinae ; COREMI is strengthening the existing networks and fostering collaboration between EU countries in order to cooperate for the safeguard of human and animal health, and to protect the poultry industry.
