Millions of Genetically Modified Mosquitoes Could Be Released in Florida

Scientists could release millions of genetically modified mosquitoes in the Florida Keys in an attempt to kill off insects that spread the diseases dengue and chikungunya—if their proposal wins regulatory approval. The male mosquitoes, created by British biotech firm Oxitec, are engineered to keep their partners from producing offspring when they mate in the wild, the Sun Sentinel reports. The number of mosquitoes capable of spreading the diseases would be reduced if enough wild mosquitoes mate with the genetically modified population. “This is essentially using a mosquito as a drug to cure disease,” Michael Doyle, executive director of the Florida Keys Mosquito Control District, told the Sun Sentinel. Despite the benefits of reducing incidences of dengue and chikungunya, two viral diseases that cause a number of uncomfortable conditions, many are wary about releasing genetically modified organisms into the wild. More than 130,000 people have signed a Change.org petition opposing the release of the mosquitoes in the Florida Keys. [Sun Sentinel]

Abstract Aedes (Stegomyia) aegypti is a cosmopolitan species that transmits arbovirus of medical importance as dengue, Zika, and chikungunya. The main strategy employed for the control of this mosquito is the use of larvicidal agents. However, the overuse of synthetic chemical larvicides has led to an increase in resistant insects, making management difficult. Therefore, the use of botanical insecticide-based nanosystems as an alternative to the use of synthetic agents for the control of Ae. aegypti has gained more considerable attention in the last years, mainly due to the advantages of nanostructured delivery sy...

va MM, Gomes CES Abstract The Dengue, Zika and Chikungunya viruses have been spreading in tropical regions, causing epidemics with high morbidity rates and fatal cases. The aim of this study was to assess the diversity and abundance of culicid species and the presence of arboviruses in mosquitoes, at the epicenter of an epidemic outbreak that occurred in people living near an urban Atlantic Forest park. Mosquitoes were captured with a Shannon trap between 2 and 6 pm in seven months of 2019. The Chikungunya virus was investigated according to the protocol described by Lanciotti (2007). The most abundant species wer...

Abstract Aedes aegypti is the vector of important diseases like dengue, zika, chikungunya, and yellow fever. Vector control is pivotal in combating the spread of these mosquito-borne illnesses. Photoactivable larvicide curcumin obtained from Curcuma longa Linnaeus has shown high potential for Ae. aegypti larvae control. However, the toxicity of this photosensitizer (PS) might jeopardize non-target aquatic organisms. The aim of this study was to evaluate the toxicity of this PS to Daphnia magna and Danio rerio, besides assessing its mode of action through larvae biochemical and histological studies. Three PS formul...

(University of Colorado Anschutz Medical Campus) In a new study, researchers from the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus call attention to the emergence of mosquito-borne viral outbreaks in West Africa, such as dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses.

Beuret Identification and characterization of viral genomes in vectors including ticks and mosquitoes positive for pathogens of great public health concern using metagenomic next generation sequencing (mNGS) has challenges. One such challenge is the ability to efficiently recover viral RNA which is typically dependent on sample processing. We evaluated the quantitative effect of six different extraction methods in recovering viral RNA in vectors using negative tick homogenates spiked with serial dilutions of tick-borne encephalitis virus (TBEV) and surrogate Langat virus (LGTV). Evaluation was performed using qPCR and...

by Doug E. Brackney, Maria A. Correa, Duncan W. Cozens Macroautophagy is an evolutionarily conserved cellular process critical for maintaining cellular homeostasis. It can additionally function as an innate immune response to viral infection as has been demonstrated for a number of arthropod-borne (arbo-) viruses. Arboviruses are maintained in a trans mission cycle between vertebrate hosts and invertebrate vectors yet the majority of studies assessing autophagy-arbovirus interactions have been limited to the mammalian host. Therefore we evaluated the role of autophagy during arbovirus infection of the invertebrate vector ...

Conclusions/SignificanceThis study showed the ubiquitous distribution and abundance ofAe.polynesiensis on the three islands and demonstrated that local populations were able to transmit CHIKV. Combined with the presence and expansion ofAe.aegypti on the main island of Wallis, these data highlight the risk of transmission of arboviral diseases in the territory of Wallis and Futuna and provide relevant information for entomological surveillance and vector control programs.

Abstract Arboviruses transmitted by Aedes mosquitoes are a growing global concern; however, there remain large gaps in surveillance of both arboviruses and their vectors in West Africa. We reviewed over 50 years of data including outbreak reports, peer-reviewed literature, and prior data compilations describing Zika, dengue, and chikungunya, and their vectors in West Africa. Large outbreaks of dengue, Zika, and chikungunya have recently occurred in the region with over 27,000 cases of Aedes-borne disease documented since 2007. Recent arboviral outbreaks have become more concentrated in urban areas, and Aedes albop...

Abstract Aedes aegypti is the main mosquito vector of dengue, zika, chikungunya, and yellow fever diseases. The low effectiveness of vector control options is mainly related to the increased insect's resistance and to the toxicity of products used for non-target organisms. The development of new environmentally friendly and safer products is imperative. Technical cashew nut shell liquid (tCNSL), mostly composed by cardanol (C), is an abundant by-product of the cashew (Anacardium occidentale L.) production chain, available at low cost, and with proven larvicidal activity. However, chemical modifications in both tCN...
