In poultry industry, the control of the red mite Dermanyssus gallinae primarily relies worldwide on acaricides; the most widely used are carbamates, followed by amidines, pyrethoids and organophosphorus. Despite their proved efficacy against D. gallinae, none of these compounds is specifically registered in Italy for use against red mites, except for the very recently labeled organophosphate and spinosad-based products; moreover, carbaryl is banned since 2007 by the UE. In the last few years, some acaricides have become worldwide less effective; thus, to control mite infestations farmers are keen to use chemicals at higher concentrations and more frequently. This improper use of acaricides to control D. gallinae could lead firstly to the development of acaricide-resistant D. gallinae populations, and, more importantly, to the accumulation of acaricides in chickens' organs, in tissues and in eggs.

Abstract
In poultry industry, the control of the red mite Dermanyssus gallinae primarily relies worldwide on acaricides; the most widely used are carbamates, followed by amidines, pyrethoids and organophosphorus. Despite their proved efficacy against D. gallinae, none of these compounds is specifically registered in Italy for use against red mites, except for the very recently labeled organophosphate and spinosad-based products; moreover, carbaryl is banned since 2007 by the UE. In the last few years, some acaricides have become worldwide less effective; thus, to control mite infestations farmers are keen to use chemicals at higher concentrations and more frequently. This improper use of acaricides to control D. gallinae could lead firstly to the development of acaricide-resistant D. gallinae populations, and, more importantly, to the accumulation of acaricides in chickens' organs, in tissues and in eggs. In the present contribution the authors summarize the situation on dermanyssosis control in Italy, their scientific experiences, and invite vets and farmers to better manage infestation in order to limit the consequences of misuse of chemicalsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
