The susceptibility of the poultry red mite,Dermanyssus gallinae (De Geer, 1778), to some acaricides under laboratory conditions

Abstract

Toxicity of 14 selected acaricides was tested for a laboratory strain of female D. gallinae. The most toxic were carbaryl (LC50 = 5.0 micrograms/m2), deltamethrin (LC50 = 7.8 micrograms/m2), bendiocarb (LC50 = 11.1 micrograms/m2), and permethrin (LC50 = 12.6 micrograms/m2). High level resistance to DDT in D. gallinae was recorded, with factors of resistance at LC50/LC90 reaching 57/73.

Evaluation of the poultry red mite, Dermanyssus gallinae (Acari: Dermanyssidae) susceptibility to some acaricides in field populations from Italy

“…Also, resistence to DDT, organophosphates or pyrethroids has been suspected in the former Czechoslovakia (Zeman and Zelezný 1985) and in Italy since in the 1980s (Genchi et al 1984). This study is the first report of tolerance to carbamate and pyrethroid in a field population of D. gallinae from Northern to Southern Italy.…”

“…Although the efficacy of several acaricides have been tested in vitro against D. gallinae using different techniques (Fletcher and Axtell 1991;Zeman and Zelezný 1985;Zeman 1987;Abo-Taka 1990;Beugnet et al 1997), none of them are specifically labelled for use against red mites. Moreover, some are unsuitable from a food safety point of view and for environmental reasons and some are now banned by the EU (such as carbamates).…”

In vitro efficacies of oils, silicas and plant preparations against the poultry red mite Dermanyssus gallinae

“…Several synthetic acaricide classes are widely used for mite control (organophosphates, pyrethroids, carbamates), but D. gallinae has developed resistance against some of these compounds (Zeman and Zelezny 1985;Beugnet et al 1997;Nordenfors et al 2001). In addition, some compounds are unsuitable for food safety and environmental reasons (Chauve 1998).…”

Understanding the biology and control of the poultry red miteDermanyssus gallinae: a review

“…PRM populations are known to be resistant to earlier generations of neurological pesticides, such as dichlorodiphenyltrichloroethane and the pyrethroids (Zeman & Železný, 1985;Beugnet et al, 1997). Dichlorodiphenyltrichloroethane is now banned for pesticidal control within the EU (UNEP-Chemicals, 2006) as it accumulates to high concentrations in food chains, persists in the fatty tissues of Figure 3.…”

“…Reports of PRM resistance to acaricidal drugs containing amitraz, carbaryl and permethrin (Zeman & Železný, 1985;Beugnet et al, 1997;Marangi et al, 2009), allied with genetic variation between red mite populations (Brännström et al, 2008;Potenza et al, 2009;Roy & Buronfosse, 2011), suggest there is an urgent requirement for research to uncover more specific control strategies. Detailed knowledge of D. gallinae biology and behaviour is comparatively underrepresented in the literature, given its commercial impact; this was estimated, for instance, in 2005 to cause an economic loss of €130 million per annum in Europe alone (Van Emous, 2005).…”
