Insecticide resistance in house flies from caged‐layer poultry facilities

Abstract

The frequency of resistance of eight strains of house flies, Musca domestica L., collected from caged‐layer poultry facilities across New York state, to nine insecticides (dimethoate, tetrachlorvinphos, permethrin, cyfluthrin, pyrethrins, methomyl, fipronil, spinosad and cyromazine) was measured relative to a laboratory susceptible strain. Percentage survival was evaluated at five diagnostic concentrations: susceptible strain LC99, 3 × LC99, 10 × LC99, 30 × LC99 and 100 × LC99. The highest levels of resistance were noted for tetrachlorvinphos, permethrin and cyfluthrin. There was substantial variation in the levels of resistance to the different insecticides from one facility to another, independent of their geographical location. There was very little cross‐resistance detected in these populations to either fipronil or spinosad. Overall, there was a good correlation between insecticide use histories and the levels of resistance. The apparent isolation of fly populations within poultry facilities suggests that there are good opportunities for the implementation of successful resistance management strategies at these facilities. Differences between these results and those of a resistance survey on New York dairy farms in 1987 are discussed. © 2000 Society of Chemical Industry

The nicotinic acetylcholine receptor subunit Mdα6 from Musca domestica is diversified via post‐transcriptional modification

“…The rspin strain is genetically similar to the aabys strain, except for the spinosad resistance locus on autosome 1 (Shono & Scott, 2003). Flies were maintained in the laboratory as previously described (Scott et al ., 2000).…”

The re‐emergence of the bed bug as a nuisance pest: implications of resistance to the pyrethroid insecticides

“…The control of bed bugs within poultry facilities is therefore particularly challenging (Axtell, 1999) and requires thorough cleaning of the facilities and associated equipment followed by insecticide application. Surprisingly to date there are no reports of pyrethroid resistance associated with bedbugs from poultry houses, in spite of reports of high levels of pyrethroid resistance in other pests that frequent these facilities such as filth flies (Scott et al , 2000), Northern fowl mites (Mullens et al , 2004), red poultry mites (Beugnet et al , 1997), fleas and lesser mealworms (Hamm et al , 2006; Lambkin & Furlong, 2011). This implies that poultry houses are unlikely to be the source of the current pyrethroid‐resistant bed bug haplotypes now being increasingly encountered in residential settings, although this has still to be confirmed by experimental testing.…”

Repellent, larvicidal and pupicidal properties of essential oils and their formulations against the housefly, Musca domestica

“…Among pesticides, organochlorines, organophosphates and, more recently, pyrethroids have been used for housefly control. However, houseflies can develop resistance to these pesticides (Scott et al , 2000; Shono & Scott, 2003; Srinivasan et al , 2008). Moreover, the excessive use of synthetic pesticides has resulted in enhanced pest resurgence, toxicological implications for human health and increased environmental pollution (Farnham, 1973).…”
