Pristup eradikacije Demanyssus gallinae - primena inertnih jedinjenja i integralna zdravstvena zaštita živine

Abstract

The generally accepted approach to D. gallinae control is based on the control of infestations. The reduction of D. gallinae infection to an acceptable level and temporarily preventions is significant impact on the health status of livestock. However, the reduced number of D. gallinae continues to persist in the poultry environment and infestation is intensively increasing. It leaves the possibility of transmitting infectious and contagious diseases. In respect of suppression, the eradication approach completely eliminates D. gallinae. On this way the impact on the general health status of the flock vanish, and provide an important assumption in the control of infectious, especially infectious diseases (which it transmits), but also eliminates all other adverse effects. In laboratory conditions, biological efficiency and selection of inert compounds were determined. The previous experience of the practical application of SiO2 formulations confirmed the possibility of successful eradication in 8 cases (combined application of liquid and powder form). A new generation of inert compounds (P 547/17) shows a highest level of advanced properties compare with SiO2 formulations, especially high and long-lasting residual effects on non-absorbent surfaces. The layer that formed a 20% working emulsion on a metal substrate, in laboratory conditions, after 7 months exhibits efficiency of 92%, in an exposure of 1 hour. In clinical conditions, even after 6.5 months of the settlement of the flock, the presence of mites was not detected. Clinical tests of inert oils are still ongoing, but now it is already evident that they have a high potential for eradication of D. gallinae. The eradication of D. gallinae is not easy procedure, which can be performed at all times and in all conditions. Conditions for the eradication of D. gallinae with inert compounds are hygienic precaution of empty objects, adequate application of selected compounds, and then break in temperature conditions of mite activity. The program of D. gallinae control includes procedures for the preparation, implementation, eradication checks, and prevention of reinfestation.
