Malaria vector control relies on toxicity of insecticides used in long lasting insecticide treated nets and indoor residual spraying. This is despite evidence that sub-lethal insecticides reduce human-vector contact and malaria transmission. The impact of sub-lethal insecticides on host seeking and blood feeding of mosquitoes was measured. Taxis boxes distinguished between repellency and attrac...

Commercially available wood-fiber pots used to collect resting mosquitoes were modified to improve sampling efficiency. The modified traps, called the Centers for Disease Control and Prevention resting traps, collected 16.0 and 5.2 times more adult Culex pipiens and Cx. tarsalis than the conventional wood-fiber pots. The resting trap increases the mean number of resting mosquitoes collected per...

The impact of optimal temperature, osmotic pressure, and diet viscosity on the number of mosquitoes (Anopheles stephensi) feeding through a membrane, and on the size of the blood meal, was evaluated. An increase in diet viscosity decreased the number of imbibing mosquitoes, reduced the size of the ingested meal, and resulted in a slower rate of weight loss after feeding. The possible effect of ...

UNLABELLED Controlled human malaria infection (CHMI) is a powerful method for assessing the efficacy of anti-malaria vaccines and drugs targeting pre-erythrocytic and erythrocytic stages of the parasite. CHMI has heretofore required the bites of 5 Plasmodium falciparum (Pf) sporozoite (SPZ)-infected mosquitoes to reliably induce Pf malaria. We reported that CHMI using the bites of 3 PfSPZ-infec...

BACKGROUND Buruli ulcer, the third mycobacterial disease after tuberculosis and leprosy, is caused by the environmental mycobacterium M. ulcerans. There is at present no clear understanding of the exact mode(s) of transmission of M. ulcerans. Populations affected by Buruli ulcer are those living close to humid and swampy zones. The disease is associated with the creation or the extension of swa...

Malaria is a vector-borne disease transmitted by Anopheles mosquitoes, in particular gambiae s.l. To identify malaria vectors and establish link between the presence of prevalence, study was carried out 7 localities Kara region: Lassa-Bas, Sarakawa, Kpindi Kozah prefecture Siou, Défalé, Ténéga Broukou Doufelgou prefecture. Two indicators were evaluated including prevalence rate as well consulta...

BACKGROUND In 2010, 2012, 2013 and 2014 dengue outbreaks have been reported in Dar es Salaam, Tanzania. However, there is no comprehensive data on the risk of transmission of dengue in the country. The objective of this study was to assess the risk of transmission of dengue in Dar es Salaam during the 2014 epidemic. METHODOLOGY/PRINCIPAL FINDINGS This cross-sectional study was conducted in Da...

This work is devoted to analyzing an impulsive control synthesis maintain the self-sustainability of Wolbachia among Aedes Aegypti mosquitoes. The present paper provides a fractional order invasive model. Through fixed point theory, this derives existence and uniqueness results for proposed Also, we performed global Mittag-Leffler stability analysis via Linear Matrix Inequality theory Lyapunov ...

there was a statistically significant difference in the number of oocysts, developed in anopheles stephensi which had fed on mice infected with chloroquine resistant strains (ny 151./2b and. p.y. nigeriensis) and treated with 1 or 10 mg/kg chloroquine phosphate, when compared with the mosquitoes fed on saline injected control animals infected with the same lines. there was no significant differ...

Novel strategies are required to control mosquitoes and the pathogens they transmit. One attractive approach involves maternally inherited endosymbiotic Wolbachia bacteria. After artificial infection with Wolbachia, many mosquitoes become refractory to infection and transmission of diverse pathogens. We evaluated the effects of Wolbachia (wAlbB strain) on infection, dissemination and transmissi...
