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.
