Arboviruses and the challenge to establish systemic and persistent infections in competent mosquito vectors : the interaction with the RNAi mechanism [PDF]

open access: yes, 2019
Arboviruses are capable to establish long-term persistent infections in mosquitoes that do not affect significantly the physiology of the insect vectors. Arbovirus infections are controlled by the RNAi machinery via the production of viral siRNAs and the

Potency of agarose gel‐supported lipid bilayers for electrophysiologic analysis of channel pores formed by Bacillus thuringiensis insecticidal proteins

open access: yesThe FEBS Journal, EarlyView.
Agarose gel‐supported lipid bilayers constructed at the interface between the lipid solution and the recording solution are useful for measuring channel currents through different types of toxin pores. In this system, the lipid bilayers can be easily reconstructed even after the bilayer is disrupted, and measurements of toxin pores could be repeated ...

Emergência de Aedes albopictus em recipientes artificiais

open access: yesRevista de Saúde Pública
OBJETIVO: Estimar o potencial de emergência média diária de adultos fêmeas de Aedes albopictus, espécie que, embora não tenha sido incriminada, até o momento, como vetora de dengue no Brasil, é muito próxima de Aedes aegypti.

A notorious vector-borne disease: Dengue fever, its evolution as public health threat

open access: yesJournal of Family Medicine and Primary Care, 2019
Dengue fever, the most notorious of vector borne diseases is under global resurgence. Incidence has increased 30 fold with global expansion. It is thus imperative to review the origin, history and current epidemiology of dengue, its transmission, factors

Automatic Detection of Aedes aegypti Breeding Grounds Based on Deep Networks with Spatio-Temporal Consistency [PDF]

open access: yesarXiv, 2020
Every year, the Aedes aegypti mosquito infects millions of people with diseases such as dengue, zika, chikungunya, and urban yellow fever. The main form to combat these diseases is to avoid mosquito reproduction by searching for and eliminating the potential mosquito breeding grounds. In this work, we introduce a comprehensive dataset of aerial videos,

INSECT LIFE AND LETTERS: THE STUDIES OF HANNS HEINZ EWERS AND OTTO AND ROSE HECHT

open access: yesGerman Life and Letters, EarlyView.
ABSTRACT This article argues that vast histories of war and displacement in the twentieth century are connected to the small and almost unnoticeable lives of insects, and that philology has much to gain from paying attention to insect worlds. We examine two case studies: the work of the German entomologist Otto Hecht and his wife, Rose Caro Hecht, and ...

The Role of Temperature in Transmission of Zoonotic Arboviruses

open access: yesViruses, 2019
We reviewed the literature on the role of temperature in transmission of zoonotic arboviruses. Vector competence is affected by both direct and indirect effects of temperature, and generally increases with increasing temperature, but results may vary by ...

On the use of the sterile insect technique or the incompatible insect technique to reduce or eliminate mosquito populations [PDF]

open access: yesarXiv, 2018
Vector control is critical to limit the circulation of vector-borne diseases like chikungunya, dengue or zika which have become important issues around the world. Among them the Sterile Insect Technique (SIT) and the Incompatible Insect Technique (IIT) recently aroused a renewed interest.

Monotonicity properties arising in a simple model of Wolbachia invasion for wild mosquito populations [PDF]

open access: yesarXiv, 2020
In this paper, we propose a simplified bidimensional Wolbachia infestation model in a population of Aedes aegypti mosquitoes, preserving the main features associated with the biology of this species that can be found in higher-dimensional models.
