Dermanyssus gallinae or the poultry red mite is currently the most im- portant ectoparasite aff ecting egg-laying hens in several countries causing reduced poultry welfare, mortality and even allergic reactions in poultry farms workers. Its short life cycle, which in optimal conditions can be com- pleted within 7 days, and ability to survive in extreme circumstances with- out a blood meal up to 13 months, and the ability to infest new fl ock, makes it even more diffi cult to eradicate. Dermanyssus gallinae prevalence rates in diff erent European countries, including Serbia, can reach up to 80-90%. Also, the poultry red mite is responsible in vector transmission of several bacterial and viral avian diseases, including Salmonella spp, Chlamydia spp., Escherichia coli, Staphylococcus spp., Pasteurella multocida, Newcas- tle disease and Fowl poxvirus. Besides that, the poultry red mite can also transfer antimicrobial resistance genes by carrying pathogenic bacterial fl ora. Control of Dermanyssus gallinae can be divided into conventional and alternative methods. Conventional methods are mostly focused on pre- venting infestations and/or killing Dermanyssus gallinae, while alternative methods include the use of essential oils, vaccines, light, odors, predatory mites, fungi, nematodes and bacterial endosymbionts, and temperature in order to eliminate the poultry red mite. Nevertheless, this small ectopara- site still makes millions worth damage to global poultry industry.
