Stability of the Virome in Lab- and Field-Collected Aedes albopictus Mosquitoes across Different Developmental Stages and Possible Core Viruses in the Publicly Available Virome Data of Aedes Mosquitoes KU Leuven

Chenyan Shi, Lu Zhao, Evans Atoni, Weifeng Zeng, Xiaomin Hu, Jelle Matthijnssens, Zhiming Yuan, Han Xia
Aedes mosquitoes can efficiently transmit many pathogenic arboviruses, placing a great burden on public health worldwide. In addition, they also carry a number of insect-specific viruses (ISVs), and it was recently suggested that some of these ISVs might form a stable species-specific "core virome" in mosquito populations. However, little is known about such a core virome in laboratory colonies and if it is present across different developmental ...

Past and future spread of the arbovirus vectors Aedes aegypti and Aedes albopictus Institute of Tropical Medicine

The global population at risk from mosquito-borne diseases-including dengue, yellow fever, chikungunya and Zika-is expanding in concert with changes in the distribution of two key vectors: Aedes aegypti and Aedes albopictus. The distribution of these species is largely driven by both human movement and the presence of suitable climate. Using statistical mapping techniques, we show that human movement patterns explain the spread of both ...

STtech: sampling and transport techniques for Aedes eggs during a sampling campaign in a low-resource setting Institute of Tropical Medicine

Container-breeding Aedes spp. (Diptera: Culicidae) mosquitoes can be surveilled at low cost using ovitraps. Hence, this method is a preferred monitoring approach of dengue vectors in low-resource settings. The ovitraps consist of a cup filled with water and an oviposition substrate for female mosquitoes. The attractiveness of the substrates for female mosquitoes can greatly differ due to differences in texture, color, and smell of the ...

Cost of intensive routine control and incremental cost of insecticide-treated curtain deployment in a setting with low Aedes aegypti infestation Institute of Tropical Medicine Ghent University

INTRODUCTION: Information regarding the cost of implementing insecticide-treated curtains (ITCs) is scarce. Therefore, we evaluated the ITC implementation cost, in addition to the costs of intensive conventional routine activities of the Aedes control program in the city of Guantanamo, Cuba.

METHODS: A cost-analysis study was conducted from the perspective of the Aedes control program, nested in an ITC effectiveness trial, during ...

No effect of insecticide treated curtain deployment on Aedes infestation in a cluster randomized trial in a setting of low dengue transmission in Guantanamo, Cuba Ghent University Institute of Tropical Medicine

Maria Eugenia Toledo, Veerle Vanlerberghe, Isora Lambert, Domingo Montada, Alberto Baly, Patrick Van Der Stuyft
Objective & Methodology : The current study evaluated the effectiveness and cost-effectiveness of Insecticide Treated Curtain (ITC) deployment for reducing dengue vector infestation levels in the Cuban context with intensive routine control activities. A cluster randomized controlled trial took place in Guantanamo city, east Cuba. Twelve neighborhoods (about 500 households each) were selected among the ones with the highest Aedes infestation ...

Differential Transmission of Antiviral Drug-Resistant Chikungunya Viruses by Aedes Mosquitoes KU Leuven

Leen Delang, Pei-Shi Yen, Thomas Vallet, Marie Vazeille, Marco Vignuzzi, Anna-Bella Failloux
The chikungunya virus (CHIKV) is transmitted by female Aedes aegypti and Aedes albopictus mosquitoes, mostly present in (sub)tropical regions. No antivirals are available to treat CHIKV infections. If antiviral drugs are proven efficient to treat CHIKV-infected patients, it will be pivotal to determine whether drug-resistant viruses can be transmitted from one human to another by their mosquito vectors. We orally infected Aedes aegypti ...

The global distribution of the arbovirus vectors Aedes aegypti and Ae. albopictus

Moritz U G Kraemer, Marianne E Sinka, Kirsten A Duda, Adrian Q N Mylne, Freya M Shearer, Christopher M Barker, Chester G Moore, Roberta G Carvalho, Giovanini E Coelho, Wim Van Bortel, et al.

Dengue and chikungunya are increasing global public health concerns due to their rapid geographical spread and increasing disease burden. Knowledge of the contemporary distribution of their shared vectors, Aedes aegypti and Aedes albopictus remains incomplete and is complicated by an ongoing range expansion fuelled by increased global trade and travel. Mapping the global distribution of these vectors and the geographical determinants of their ...

Modelling seasonal dynamics, population stability, and pest control in Aedes japonicus japonicus (Diptera Culicidae) Institute of Tropical Medicine

Andreas Wieser, Friederike Reuss, Aidin Niamir, Ruth Müller, Robert B O'Hara, Markus Pfenninger

BACKGROUND: The invasive temperate mosquito Aedes japonicus japonicus is a potential vector for various infectious diseases and therefore a target of vector control measures. Even though established in Germany, it is unclear whether the species has already reached its full distribution potential. The possible range of the species, its annual population dynamics, the success of vector control measures and future expansions due to climate ...
