Aedes albopictus is a mosquito originating from Asia, which has extended its range worldwide the last decades. It competent vector for several arboviruses. was first described in La Réunion (an island of South West part Indian Ocean) 1913. Since then, it become dominant species and serious threat to public health, especially during two arboviruses outbreaks dengue (1977) chikungunya (2005–2006). Despite pest status, data on biology this are scarce, population present Ocean (IO), never been...
Chikungunya virus (CHIKV) has long been considered to be transmitted humans by the human-biting mosquito Aedes aegypti, especially in Africa. However, recent outbreak of CHIKV involved another vector, albopictus, and serological data literature suggest that several species domestic or human-related vertebrates can contaminated this virus. role Ae. albopictus mosquitoes as potential enzootic vectors for not yet evaluated. Here we investigate feeding resting behaviors an area where a epidemic...
The Anopheles midgut hosts diverse bacterial communities and represents a complex ecosystem. Several evidences indicate that mosquito microbiota interferes with malaria parasite transmission. However, the composition of salivary glands ovaries, two other biologically important tissues, has not been described so far. In this study, we investigated dynamics in tissues from emerging mosquitoes until 8 days after blood meal containing Plasmodium falciparum gametocytes temporal colonization...
In West Africa, lineage splitting between the M and S molecular forms of major Afro‐tropical malaria mosquito, Anopheles gambiae (Diptera: Culicidae), is thought to be driven by ecological divergence, occurring mainly at larval stage. Here, we present evidence for habitat segregation two in around irrigated rice fields located within humid savannahs western Burkina Faso. Longitudinal sampling adult mosquitoes emerging from a range breeding sites distributed along transect extending heart...
Disruptive selection mediated by predation on aquatic immature stages has been proposed as a major force driving ecological divergence and fostering speciation between the M S molecular forms of African malaria mosquito, Anopheles gambiae. In dry savannahs West Africa where both co-occur, form thrives in temporary pools filled with rainwater, whereas preferentially breeds permanent freshwater habitats predator pressure is higher. Here, we explored proximal mechanisms which may contribute to...
The development of Plasmodium falciparum within the Anopheles gambiae mosquito relies on complex vector-parasite interactions, however resident midgut microbiota also plays an important role in mediating parasite infection. In natural conditions, microbial flora is diverse, composed commensal and symbiotic bacteria. We report here isolation culturable bacteria from mosquitoes collected field Cameroon their identification based 16S rRNA gene sequencing. next measured effect selected bacterial...

Sicyopterus lagocephalus post-larvae migrating in Mascarene Archipelago rivers, La Réunion Island, provide an important food source to local populations and fishing activity has a socioeconomic impact. Improved knowledge of the life traits characterisation post-larval stages should enable better understanding physiological changes triggering migratory behaviour. It would also help explain recruitment processes managers implement conservation measures for stock management. is amphidromous...

Here, we explored behavioural responses to presence predator wild populations M S molecular forms An. that typically breed permanent (e.g., rice field paddies) temporary road ruts) water collections.Larvae used these experiments were obtained from eggs laid...
Many zoonotic infectious diseases have emerged and re-emerged over the last two decades. There has been a significant increase in vector-borne due to climate variations that lead environmental changes favoring development adaptation of vectors. This study was carried out improve knowledge ecology mosquito vectors involved transmission Rift Valley fever virus (RVFV) Senegal. An entomological survey conducted three Senegalese agro-systems, Senegal River Delta (SRD), (SRV) Ferlo, during rainy...

African animal trypanosomosis (AAT) was one of the main disease-related constraints to development intensive livestock production systems in Niayes region Senegal, a 30 km wide strip land along coast between Dakar and Saint-Louis. To overcome this constraint, Government Senegal initiated an area-wide integrated pest management programme combining chemical control tactics with sterile insect technique eradicate population tsetse fly Glossina palpalis gambiensis Vanderplank, 1949 (Diptera,...
Tsetse flies transmit trypanosomes that cause human and African animal trypanosomosis, a debilitating disease of humans (sleeping sickness) livestock (nagana). An area-wide integrated pest management campaign against Glossina palpalis gambiensis has been implemented in Senegal since 2010 includes sterile insect technique (SIT) component. The SIT can only be successful when the males are destined for release have flight ability, survival competitiveness as close possible to their wild male...
Abstract Explaining how and why reproductive isolation evolves determining which forms of have the largest impact on process population divergence are major goals in study speciation. By studying recent adaptive radiations incompletely isolated taxa, it is possible to identify barriers involved at early before other confounding emerge after speciation complete. Sibling species Anopheles gambiae complex offer opportunities provide insights into mechanisms. Here, we studied patterns among...
The application of the sterile insect technique (SIT) requires mass-production males good biological quality. size project area will in most cases determine whether it is more cost effective to produce flies locally (and invest a mass-rearing facility) or import from facility that located another country. This study aimed at assessing effect long distance transport male Glossina palpalis gambiensis pupae on adult fly yield. were produced Centre International de Recherche-Développement sur...
African horse sickness (AHS) is an equine disease endemic to Senegal. The virus (AHSV) transmitted the mammalian hosts by midges of Culicoides Latreille genus.
