  abstract = {{B}ackground: {U}ltra-low volume ({ULV}) insecticidal aerosols dispensed from vehicle-mounted cold-foggers are widely considered the method of choice for control of {A}edes aegypti and {A}e. albopictus during outbreaks of dengue and chikungunya and, more recently, {Z}ika. {N}evertheless, their effectiveness has been poorly studied, particularly in {E}urope. {N}early all published studies of {ULV} efficacy are bio-assays based on the mortality of caged mosquitoes. {I}n our study we preferred to monitor the direct impact of treatments on the wild mosquito populations. {T}his study was undertaken to evaluate the efficiency of the two widely used space spraying methods to control {A}e. albopictus and {A}e. aegypti. {M}ethods: {W}e determined the susceptibility of local {A}e. albopictus to deltamethrin by two methods: topical application and the "{WHO} {T}ube {T}est". {W}e used ovitraps baited with hay infusion and adult traps ({B}-{G} {S}entinel) baited with a patented attractant to monitor the mosquitoes in four residential areas in {N}ice, southern {F}rance. {T}he impact of deltamethrin applied from vehicle-mounted {ULV} fogging-machines was assessed by comparing trap results in treated vs untreated areas for 5 days before and 5 days after treatment. {F}our trials were conducted at the maximum permitted application rate (1 g.ha-1). {W}e also made two small-scale tests of the impact of the same insecticide dispensed from a hand-held thermal fogger. {R}esults: {S}usceptibility to the insecticide was high but there was no discernable change in the oviposition rate or the catch of adult female mosquitoes, nor was there any change in the parous rate. {I}n contrast, hand-held thermal foggers were highly effective, with more than 90% reduction of both laid eggs and females. {C}onclusions: {W}e believe that direct monitoring of the wild mosquito populations gives a realistic assessment of the impact of treatments and suggest that the lack of efficacy is due to lack of interaction between the target mosquitoes and the {ULV} aerosol. {W}e discuss the factors that influence the effectiveness of both methods of spraying in the context of epidemic situations.},
