New study explores the chemistry and alarming history of fast-acting insecticide

A new study in the Journal of the American Chemical Society explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide.

New solution can limit spread of wild-released gene drives to target populations

By altering the heritability of certain traits, gene drive technologies have the potential to spread desired genes through wild populations.

Computational analysis identifies key uncertainties for models of mosquito distribution in the U.S.

A computational analysis has identified key regions in the United States where model-based predictions of mosquito species distribution could be improved. Andrew Monaghan of the University of Colorado Boulder and colleagues present these findings in PLOS Computational Biology.

Stanford study finds genetic similarities among species that use sound waves to navigate

Insect-eating bats navigate effortlessly in the dark and dolphins and killer whales gobble up prey in murky waters thanks in part to specific changes in a set of 18 genes involved in the development of the cochlear ganglion -- a group of nerves that transmit sound from the ear to the brain, according to a study by researchers at Stanford University.

Study brings new understanding in the battle against mosquito-borne diseases

In two recent studies, including one published Oct. 1 in Trends in Parasitology, medical entomologist Riley Tedrow found that malaria-carrying mosquitoes in Madagascar, an African island nation, feed on the blood of humans and other mammals more frequently than assumed, which increases opportunities for disease transmission.

New leishmaniasis look-alike parasitic infection reported

A new study published online in the journal Emerging Infectious Diseases describes the appearance of a new protozoan infection carried by insects which causes symptoms that mimic the disease called visceral leishmaniasis, caused by a different parasite.

Study: Transmission of protozoan parasite may cause leishmaniasis-like symptoms in people

A new study published this week online in Emerging Infectious Diseases suggests that transmission of a protozoan parasite from insects may also cause leishmaniasis-like symptoms in people

Brazilian researchers identify new species of parasite in fatal case of visceral leishmaniasis

Brazilian researchers believe they have identified in patients treated at the University Hospital (HU) in Aracaju, state of Sergipe, a new species of parasite that can cause a disease similar to visceral leishmaniasis but is resistant to the treatments currently available.

Closely spaced habitats are more likely to be used by mosquitoes to lay eggs

Patches of standing water that are close together are more likely to be used by mosquitoes to lay eggs in than patches that are farther apart, according to a new study from the University of Georgia. The findings, recently published in Oecologia, have implications for human and animal health.

Molecular changes are linked with adverse events following treatment of lymphatic filariasis

The Global Program to Eliminate Lymphatic Filariasis delivers mass drug administration to 500 million people each year, and adverse events are common following treatment. Now, researchers have reported in PLOS Neglected Tropical Diseases that certain changes in gene expression are associated with these adverse events.

Brain-infecting virus has spread across the US at record rates this year

Health officials have announced over the weekend that more people have been infected with or died from the EEE virus, making 2019 the worst year yet for recorded cases.

Mutations in specific protein make dengue virus resistant to vaccines and therapeutics

Dengue virus infects about 400 million people annually around the world, with a high prevalence in tropical and sub-tropical regions.

Invasive mosquitoes plunge deeper into California

Two invasive species of mosquitoes that can carry Zika, dengue, yellow fever and other dangerous viruses are spreading in California — and have been found as far north as Sacramento and Placer counties.

A single dose of yellow fever vaccine does not offer long-term immunity to children

Yellow fever is a viral infection spread by various species of mosquito and is rife in 34 countries in Africa and 13 in Latin America.

Concerns over GM mosquitoes released in Brazil

A field experiment that released genetically modified mosquitoes in Brazil to control natural populations of the insect may have had unintended consequences.

Low blood iron levels increase risk of Dengue

The more anemic you are, the more likely it is that you could spread dengue fever because mosquitoes feeding on your blood have a greater chance of picking up the virus. This was reported by a new study published in the journal Nature Microbiology on September 16, 2019.

Clinically undetectable Plasmodium relapse infections may still pose a threat

Nonhuman primates with clinically undetectable Plasmodium relapse infections still harbor parasitic gametocytes that may be infectious to mosquitoes, according to a study published September 19 in the open-access journal PLOS Pathogens by F. Eun-Hyung Lee and Mary R. Galinski of Emory University, Tracey J. Lamb of the University of Utah, and colleagues.

Dengue fever is endemic in places where iron deficiency is more common

Mosquitoes are more likely to acquire the dengue virus when they feed on blood with low levels of iron, researchers report in the 16 September issue of Nature Microbiology.

West Nile Virus samples found 10 miles apart came from different places, NAU scientist finds

After sequencing more than 400 different genomes of the West Nile Virus, an NAU scientist discovered the two reports of West Nile Virus in Coconino County came from two different places. One migrated north from the Phoenix area. The other is a bit more of a mystery.
