Host age variation is a striking source of heterogeneity that can shape the evolution and transmission dynamic pathogens. Compared with vertebrate systems, our understanding impact host on invertebrate–pathogen interactions remains limited. We examined influence mosquito key life-history traits driving human malaria transmission. Females Anopheles coluzzii , major vector, belonging to three classes (4-, 8- 12-day-old), were experimentally infected Plasmodium falciparum field isolates. Our...
The ecological context in which mosquitoes and malaria parasites interact has received little attention, compared to the genetic molecular aspects of transmission. Plant nectar fruits are important for nutritional ecology vectors, but how natural diversity plant-derived sugar sources affects mosquito competence is unclear. To test this, we infected Anopheles coluzzi, an African vector, with sympatric field isolates Plasmodium falciparum, using direct membrane feeding assays. Through a series...
Background Twenty-seven villages were selected in southwest Burkina Faso to implement new vector control strategies addition long lasting insecticidal nets (LLINs) through a Randomized Controlled Trial (RCT). We conducted entomological surveys the during dry cold season (January 2017), hot (March 2017) and rainy (June describe malaria vectors bionomics, insecticide resistance transmission prior this trial. Methods carried out hourly catches (from 17:00 09:00) inside outside 4 houses each...
In the fight against malaria, transmission blocking interventions (TBIs) such as vaccines or drugs, are promising approaches to complement conventional tools. They aim prevent infection of vectors and thereby reduce subsequent exposure a human population infectious mosquitoes. The effectiveness these has been shown depend on initial intensity in mosquitoes, often measured mean number oocysts resulting from an blood meal absence intervention. mosquitoes exposed high infection, current TBI...

A survey study was carried out around two large cities in Burkina Faso to contribute the understanding of situation local milk production and processing. Twenty-two dairy farms associated with nine processing units were selected for study. Two separate questionnaires used investigate prerequisites animal interviews from August October 2006. Meanwhile, 110 samples individual cows, 22 farm tank analyzed. Results show that daily yield 1 ‑ 2 L per cow sedentary traditional 4 semi‑intensive...
Inflammation is the supreme biological response to illness. In Hauts-Bassins region, in traditional medicine, all parts of Cassia sieberiana and Piliostigma thonningii are used treat hepatitis inflammation.

Abstract Background Mosquitoes (Diptera: Culicidae) can have a significant negative impact on human health. The urbanization of natural environments and their conversion for agricultural use, as well population growth, may affect mosquito populations increase the risk emerging or re-emerging mosquito-borne diseases. We report variety number adult mosquitoes found in four with varying degrees (rural, urban, rice fields, forest) located savannah zone West Africa. Methods were collected from...

Understanding the factors that account for male mating competitiveness is critical to development of sterile insect technique (SIT). Here, effects partial sterilization with 90 Gy radiation on sexual Anopheles coluzzii allowed mate in different ratios untreated males have been assessed. Moreover, was compared between one versus two days contact females.Sterile and four six age were released large cages (~1.75 sq m) females similar at following males: virgin females: 100:100:100, 300:100:100,...
This study explored the metabolic adjustments prompted by a switch between rainy and dry season conditions in African malaria mosquitoes Anopheles gambiae (M S molecular forms) arabiensis. Mosquitoes were reared contrasted experimental reflecting environmental variation Burkina Faso. Thirty-five metabolites (including sugars, polyols, amino acids) monitored newly emerged males females, their ecdysteroid titers determined. Metabolomic signatures remarkably similar across species, when...
The success of the sterile insect technique depends, among other things, on continuous releases sexually competitive males within target area. Several factors (including high rearing density and physical manipulation, such as larvae pupae separation) can influence quality produced in mass-rearing facilities. different steps mass production laboratory may modify behaviour mosquitoes, directly or through loss natural characters a result adaptation to lab rearing, lead competitiveness male...
Abstract Mosquito-borne viruses represent a threat to human health worldwide. This taxonomically-diverse group includes numerous that recurrently spread into new regions. Thus, periodic surveillance of the arbovirus diversity in given region can help optimizing diagnosis arboviral infections. Nevertheless, such screenings are rarely carried out, especially low-income countries. Consequently, case investigation is often limited fraction diversity. situation probably results undiagnosed cases....
The success of the sterile insect technique relies, among other things, on continuous release over flooding numbers sexually competitive males into target area. To produce sufficiently large quantities males, rearing protocols need to be optimized including development and validation a standardized egg quantification method. Batches 1000 freshly laid eggs collected from standard cages were counted, gently dried under laboratory conditions (27 ± 1 °C, 75 5 % RH) combined so that 1000–8000...
Background In view of widespread pyrethroid resistance in malaria vectors Africa, two long-lasting insecticidal nets (LLINs) incorporated with a synergist, piperonyl butoxide (PBO), DawaPlus 3.0 (deltamethrin + PBO the roof panel; deltamethrin alone side panels) and 4.0 all panels), were evaluated an experimental hut trial rice growing irrigated area Burkina Faso. Efficacy was tested against free-flying vector, Anopheles gambiae s.l., high involving L1014F kdr CYP6P3P450 mechanisms....

Entomological surveillance of lymphatic filariasis and malaria infections play an important role in the decision-making national programs to control, or eliminate these both diseases. In areas where diseases prevalence is low, a large number mosquitoes need be sampled determine vectors infection rate. To do this, efficient mosquito collection methods must used. This study part this framework, assess appropriate for xenomonitoring coexistence context with Burkina Faso. Mosquito collections...
