Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

Insect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Full‐length transcriptome profiling of true bug mitochondrial genomes reveals the unique transcriptional regulation during insect evolution

Insect Science, EarlyView.
The mitogenome was transcribed into complete primary polycistrons on both strands. The heteropteran mitochondrial transcription termination factor (HmTTF) functions as a bidirectional attenuator rather than a terminator, and co‐evolution of HmTTF and the binding sites was observed.

A LUTA HUMANA CONTRA O Aedes aegypti

Cadernos de Pesquisa, 2013
No Brasil, a partir dos anos 60, as mudanças demográficas geradas por intenso êxodo rural resultaram em crescimento desordenado das cidades. Dois fatores que podem ter colaborado com essa desorganização são a falta de abastecimento de água, que obriga a ...

WASTE PICKER’S BEHAVIOUR ON DHF AND IT’S CORRELATION WITH THE PRESENCE OF AEDES AEGYPTI LARVA

Jurnal Ners, 2017
Introduction: Dengue Haemorhagic Fever is an endemic disease caused by dengue virus with Aedes aegypti as the vector. Most of waste pickers in waste goods pool refuse fogging, 3M programme and abatization, so that DHF outbreak occurs in that area every ...

Perturbed cholesterol and vesicular trafficking associated with dengue blocking in Wolbachia-infected Aedes aegypti cells [PDF]

, 2017
Wolbachia are intracellular maternally inherited bacteria that can spread through insect populations and block virus transmission by mosquitoes, providing an important approach to dengue control.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Aedes aegypti and Aedes albopictus (Diptera: Culicidae): coexistence and susceptibility to temephos, in municipalities with occurrence of dengue and differentiated characteristics of urbanization

Revista da Sociedade Brasileira de Medicina Tropical, 2011
INTRODUCTION: The aim of the present study was to verify the coexistence between Aedes aegypti and Aedes albopictus populations in municipalities of the States of Paraná and Santa Catarina with different urbanization profiles where dengue occurs and ...

From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

Coloration Technology, EarlyView.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this
