Abstract

The past decades of clinical practice in poultry farming are character-ized by inadequate control of one of the most important poultry ectopara-site, the red poultry mite (Dermanyssus gallinae). Therefore, the program for control of D. gallinae based exclusively ona physical mechanisms of action of acaricides has been developed in Serbia since 2012. By the beginning of 2017, a synergistic relationship between paraffi n and silicone oils was observed by our team, and its effi ciency in preventing the red poultry mite from respiring was examined. For laboratory examination the Petri dish and tin-box methods were used. Direct, full 1-minute exposure of adult mites to the recommended (15 and 20%) or even much lower concentration of the formulation resulted in 100% mortality aft er 24 hours. Subsequent 1-hour exposure (24 hours aft er application onto treated non-absorbent surface of adult mite) resulted in 100% mortality with the same concentrations. The long term eff ect depends on the surface quality. The concentrations of 15 and 20% provide 100% long-term eff ect aft er a 1-hour exposure period, and remains fully eff ective over the following 4-month period. In the following months (8 months), the formulation continues to work with a slightly lesser, however, still signifi cant eff ect. The formulation is most eff ective on a plastic surface, where the full eff ect is achieved with signifi cantly lower concentrations. The formulation has no eff ect on eggs; however, aft er the short development cycle is completed in the egg (2-6 days) and exit from the shell, the larva is immediately exposed to the eff ects of the formulation and eliminated. High effi ciency of the paraffi n and silicone oils formulation, which has been established in laboratory conditions, justifi es its use to the purpose of D. gallinae control in cages and equipment before fl ock settle-ment as well as in transport cages aft er cleaning and disinfection.
