Insecticide resistance of house fly, Musca domestica (L.) from Argentina

The status of resistance to cyromazine, 2,2-dichlorovinyl dimethyl phosphate (DDVP), and permethrin relative to field populations of the house fly, Musca domestica L. from Argentinean poultry farms was studied. All the three studied populations (SV, Q, and C) showed resistant ratios (RRs) to cyromazine of 3.9, 10.98, and 62.5, respectively. We observed high levels of resistance toward the organophosphate DDVP and permethrin. The RRs to DDVP ranged from 45.4 to 62.5. No significant differences were found among the studied populations. All the house fly populations were permethrin-resistant, in comparison with the susceptible strain. Two of the analyzed populations (SV and Q) differed significantly in toxicity to the population C. This is the first evidence that house flies from Argentina showed a multi-resistance pattern. The implementation of an insecticide monitoring program on poultry farms of Argentina is needed to prevent field control failures. Furthermore, integrated control strategies are needed to delay detrimental development of insecticide resistance.
We thank the owners of the poultry farms where house flies were collected. The present work is part of the thesis of the student Gonzalo Roca Acevedo at the CAECE University. We thank Dr. Eduardo Zerba and Dra María Inés Picollo for helping us to perform this work at the CIPEIN. Technician Susana Segovia helped us to rear the different populations. The experiments in this work comply with the current laws of Argentina.
