    Description: Les vecteurs des agents du paludisme ou de la leishmaniose, rencontrés lors de voyages dans les régions à climat chaud, s'ajoutant à la transmission par le moustique tigre (Aedes albopictus) des virus chikungunya et de la dengue dans le sud de la France, ont montré l'intérêt d'une réflexion approfondie sur la protection personnelle antivectorielle. En cas d'épidémie, nos concitoyens se protègent individuellement en se procurant sur le marché tout un arsenal de moyens où le meilleur côtoie le pire. Pour donner à chacun des informations sur l'efficacité et l'innocuité de ces moyens de protection, la Société de médecine des voyages et la Société française de parasitologie ont initié cette étude qui a pris la forme de « Recommandations de bonne pratique », en suivant le schéma élaboré par la Haute Autorité de santé. Cet ouvrage rassemble ainsi toutes les données pertinentes, validées et mises en forme pour être utilisées non seulement par les personnels de santé (médecins, pharmaciens, infirmiers), mais aussi par les agents touristiques ainsi que par les particuliers pour se protéger des nuisances et des maladies à vecteurs qui constituent de préoccupants problèmes de santé publique.

    Description: Stomoxys calcitrans is considered as a major pest of livestock worldwide. Insecticides have been extensively used to control this pest but resistance to these chemical compounds is now reported in many countries. Therefore, a more sustainable and efficient control is needed. Seven different types of blue screens, with reflectances around 460 nm, were tested during summer 2016 in southwestern France to evaluate their attractiveness and their specificity for stable flies. Height of the screen and orientation (east or west) of a blue screen were also considered. High levels of S. calcitrans captures were recorded during this study (from 141 to 7301 individuals per blue screen and per day) whereas the numbers of tabanids and pollinator insects remained extremely low (less than 10 individuals per screen and per day). No significant difference in attractiveness has been shown between the different types of blue screens. The lower half of the blue screens caught significantly more stable flies (70%) than the higher half (30%). The “east” side of the screen attracted 60% of stable flies but this was not significantly different from the west side. These results are highlighting the interest in these blue polyethylene screens for controlling stable flies in cattle farms, in comparison with more expensive blue fabrics.

    Description: The genus Haematobosca Bezzi, 1907 (Diptera: Muscidae) contains haematophagous flies of veterinary importance. A new fly species of this genus was recognised from northern Thailand based on morphological characters and described as Haematobosca aberrans Pont, Duvallet & Changbunjong, 2020. In the present study, the mitochondrial cytochrome c oxidase I (COI) gene was used to confirm the morphological identification of H. aberrans. In addition, landmark-based geometric morphometrics was used to determine sexual dimorphism. The molecular analysis was conducted with 10 COI sequences. The results showed that all sequences were 100% identical. The sequence was not highly similar to reference sequences from GenBank and did not match any identified species from Barcode of Life Data Systems (BOLD). Phylogenetic analysis clearly differentiated this species from other species within the subfamily Stomoxyinae. For geometric morphometric analysis, a total of 16 wing pictures were analysed using the landmark-based approach. The results showed significant differences in wing shape between males and females, with a cross-validated classification score of 100%. The allometric analysis showed that wing shape has no correlation with size. Therefore, the COI gene is effective in species identification of H. aberrans, and geometric morphometrics is also effective in determining sexual dimorphism.
