- W601306772 abstract "Since 90's, bed bugs (Cimex lectularius) infestations are increasing all over the world. Upon 2008, in France, very rare informations and researches on bedbugs are investigated. The objectives of this thesis work were to organise and manage a research project (PHRC 09-API-01) with french research laboratories (Nice, Marseille, Toulon, Montpellier, Bobigny, Creteil). About entomological project, we describe 81 infestations and collected 2891 bed bugs. A bed bugs maintenance of laboratory colony has been established without any animals, only on an artificial membrane with human blood. About Infectious research, 339 bedbugs have been studies for their virological and bacteriological pathogens. In virology, with the molecular probes targeted for Flavivirus, Arenavirus, Hantavirus, Phlebovirus no postivity has been observed. In bacteriology, 32 bedbugs have been positive for a bacteria dispatched as follow: 29 bed bugs for Acinetobacter, 3 for Wolbachia, 3 for Ehrlichia and 2 for Coxiella. Resistance to insecticide has been evaluated for 192 apartments in Saint Ouen City (France-93). 534 bed bugs have been collected. A total of 564 bed bugs were collected in the infested units. Bioassays and DNA sequencing showed a high frequency of resistance to pyrethroids; all bed bugs tested (n= 124) had homozygous L925I kdr-like gene mutation. The high levels of pyrethroid resistance indicate that this phenomenon is already established and prompt the need to reevaluate the wide use of pyrethroids to control bed bugs in France. Genetic analysis of french bed bug populations are still ongoing. First steps for biomolecular markers validations are finish." @default.
