An example of rational Dermanyssus gallinae control – Pulcap

Th e irrational control of Dermanyssus gallinae ectoparasites (De Geer, 1778) in intensive livestock can cause health problems, economic damage, and can also toxicologically harm the health of humans and the environ- ment. Formulation P 547/17 (Pulcap) is a new generation of inert matter (an oil). In Pulcap formulation and technology, the fulfi lment of rigorous criteria for rational control of D. gallinae were tested and present in this paper. Th ose criteria are the following: the safety of the preparation (i.e. the preparation is non-toxic); the feasibility of application of the preparation in facilities, for handling transport cages, on used cages and equipment, as well as in inhabited buildings; the method of application - the preparation is applied by spray method (external application). Th e aim of the application was also considered. It is to make the control eff ective, on the condition that eradication is feasible. Th en, the conditionality, which imply that the ap- plication of this preparation requires fulfi lling hygienic conditions, break of production in facilities, a certain temperature and professional approach to it. Th e effi cacy of the preparation is another important criterion. It implies that the clinical results of the application have been monitored in diff erent conditions at diff erent time intervals. It has been proven that there is no resistance to this preparation. Th e disadvantages of the preparations were also observed. It is the absence of prolonged action on absorbent surfaces, the delay in starting the egg bar and discharging, which increases contami- nation. Th e whole program / plan of long-term control has been developed. Th e cost-eff ectiveness of the product is the ratio of price and effi ciency on an annual level. Eradication is the most economical method of controlling D. gallinae, which relieved farmers from all further costs. Th ere is a great challenge for each type of D. gallinae control, especially the rational one. Reconsidering and further development of the approach of rational control is a way to improve the control of D. gallinae, which we want to encourage.
