The aim of this study was to analyse esterase activity levels at different ages during the life-span of adult Anopheles funestus Giles in order to better understand the complex biological processes in this species.

Bio-efficacy of new long-lasting insecticide-treated bed nets against Anopheles funestus and Anopheles gambiae from central and northern Mozambique

The study shows evidence of considerable heterogeneity in both insecticide susceptibility and the level of bio-efficacy of commonly available types of LLINs against wild A. funestus and A. gambiae from Balama, Mocuba and Milange districts, located in north and centre of Mozambique.

Humans frequently exposed to a range of non-human primate malaria parasite species through the bites of Anopheles dirus mosquitoes in South-central Vietnam

Reference:

In this study we analysed the species composition of malarial sporozoites infecting the salivary glands of Anopheles dirus in order to determine their potential role as bridge vectors of Plasmodium parasites from monkeys to humans.

Knockdown resistance (kdr) mutations in Indian Anopheles culicifacies populations

June 24, 2015 - 15:40 -- Open Access

This vector is resistant to DDT in most parts of the country with indication of emerging resistance to pyrethroids. Since knockdown resistance (kdr) is known to confer cross-resistance between DDT and pyrethroids owing to a common target site of action, knowledge of prevalence of knockdown resistance (kdr) alleles is important from insecticide resistance management point of view.

Not Open Access | Anti-CD81 but not anti-SR-BI blocks Plasmodium falciparum liver infection in a humanized mouse model

Lander Foquet, Cornelus C. Hermsen, Lieven Verhoye, Geert-Jan van Gemert, Riccardo Cortese, Alfredo Nicosia, Robert W. Sauerwein, Geert Leroux-Roels and Philip Meuleman
Reference:

These observations confirm the role of CD81 in liver-stage malaria and question that of SR-BI. CD81 might be a valuable drug target for the prevention of malaria.

Plasmodium falciparum in the southeastern Atlantic forest: a challenge to the bromeliad-malaria paradigm?

These results show that P. falciparum actively circulates, in higher proportion than P. vivax, among Anopheles mosquitoes of fragments of the southeastern Brazilian Atlantic forest.

Airport malaria: report of four cases in Tunisia

This indicates the need to consider malaria while examining airport employees or people living near international airports presenting with fever of unknown origin. It also stresses the need for effective spraying of aircrafts coming from malarious areas.

Not Open Access | Data from: Whole genome sequencing reveals absence of recent gene-flow and separate demographic histories for Anopheles punctulatus mosquitoes in Papua New Guinea

Our analysis of more than 50 Mb of orthologous DNA sequences revealed no evidence of contemporary gene flow among these mosquitoes. In addition, investigation of the demography of two of the Anopheles punctulatus species revealed distinct population histories.

Not Open Access | Editorial Commentary: Ivermectin as a Complementary Strategy to Kill Mosquitoes and Stop Malaria Transmission?

Clin Infect Dis. (2015) 60 (3): 366-368.

Thus, a systemic endectocidal drug like ivermectin, which can be given to both humans and animals and is toxic to Anopheles mosquitoes when they take a blood meal from a host that has recently received it, provides an intriguing opportunity to kill the remaining mosquitoes that avoid or survive our existing vector control interventions

NOT Open Access | Antiviral immunity of Anopheles gambiae is highly compartmentalized, with distinct roles for RNA interference and gut microbiota

We compare them with the responses of the post-midgut systemic compartment, which is the site of the subsequent disseminated viral infection. Normal viral infection of the midgut requires bacterial flora and is inhibited by the activities of immune deficiency (Imd), JAK/STAT, and Leu-rich repeat immune factors.
