Environmental mutations in the Campo focus challenge elimination of sleeping sickness transmission in Cameroon

Medical and Veterinary Entomology, Volume 36, Issue 3, Page 260-268, September 2022., 2022
High densities of tsetse fly vectors of Human sleeping sickness and animal trypanosomoses are recorded in the transborder focus of Campo, South Cameroon. Around 20% of these flies are infected with trypanosome parasites, among which Trypanosoma brucei gambiense, the human parasite.

Genetic diversity and phylogenetic relationships of tsetse flies of the palpalis group in Congo Brazzaville based on mitochondrial cox1 gene sequences

Parasites & Vectors, 2020
Background Despite the morphological characterization established in the 1950s and 1960s, the identity of extant taxa that make up Glossina fuscipes (s.l.) in the Congo remains questionable. Previous claims of overlap between G.

Prospects for developing efficient targets for the xenomonitoring and control of Simulium damnosum s.l., the major vectors of onchocerciasis in Africa

Medical and Veterinary Entomology, Volume 36, Issue 3, Page 235-246, September 2022., 2022
Highlight 1: Our results revealed that smaller targets attract as many savanna S. damnosum than largest ones. Highlight 2: Horizontal oblongs targets are more attractive to savanna S. damnosum. Highlight 3: Horizontal oblong target baited with POCA blend collected highly number of savanna S. damnosum.

Instraspecific variations of wing and thorax size of Glossina palpalis palpalis (Robineau-Desvoidy, 1830) in the forest region of Côte d'Ivoire

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2000
Thorax and wing morphometry was studied in 497 Glossina palpalis palpalis caught on the outskirts of a village in the center-west of Côte d’Ivoire. Significant size differences were observed depending on the sex and season of catching.

Troubles de la reproduction dans un élevage en laboratoire de Glossana palpalis palpalis Robineau-Desvoidy (Diptera : Glossinidae)

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1995
Les troubles de la reproduction ont été utilisés comme paramètre pour l'évaluation de la baisse de fécondité d'une colonie de G. p. palpalis. Les résultats ont montré que l'avortement représentait la forme la plus courante des troubles de la fonction de ...
