Did the Malaria Parasite First Evolve in the Insect Vector or the Vertebrate Host?


By John P. Roche Malaria is a terrible problem, killing nearly half a million people per year, mostly in sub-Saharan Africa. This serious disease is caused by a protozoan parasite of the genus Plasmodium, which is spread to humans by mosquitoes of the genus Anopheles. In the Anopheles mosquito, the life cycle of the parasite […]

Anopheles Mosquitoes as Vectors of Malaria in East Africa: Bed Nets and Beyond

Anopheles gambiae

By John P. Roche Malaria is a devastating disease, with almost two hundred million cases and half a million deaths per year worldwide. The World Health Organization estimates that the rate of mortality from malaria has decreased 47% since the year 2000, and the reduction in the rate of mortality has been even more impressive […]

New Research May Lead to Breathalyzer Test for Malaria


According to the World Health Organization, more than 500,000 people die each year from malaria, a disease that is transmitted by mosquitoes in the genus Anopheles. In addition to the half a million deaths, about 200 million people are infected annually. Now researchers at Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian […]

OUP Supporting World Malaria Day by Highlighting Top Articles


World Malaria Day is Saturday, April 25, 2015 The World Health Organization (WHO) estimates that 584,000 people died in 2013 from malaria, a preventable and curable disease transmitted to people through the bites of infected Anopheles mosquitoes. Nearly half of the world’s population is at risk, but the most common victims are women and children […]

Tom Turpin Talks about Louse Dislodgers, Malaria and Powdered Wigs


Dr. Tom Turpin, a professor of entomology at Purdue University, was recently interviewed by a local TV station about insect myths and how they originated. In the following video, he discusses the entomological origins of “louse dislodgers” (otherwise known as back-scratchers), perfume (used to purify air in order to protect people from malaria), and powdered […]

Bacterium May Make Mosquitoes Less Susceptible to Dengue and Malaria


Just like those of humans, insect guts are full of microbes, and the microbiota can influence the insect’s ability to transmit diseases. A study published in PLOS Pathogens reports that a bacterium isolated from the gut of an Aedes mosquito can reduce infection of mosquitoes by malaria parasites and dengue virus. The bacterium can also […]

Mosquitoes Modified to Create Only Male Offspring Could Help Eradicate Malaria


Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. In a study published in the journal Nature Communications, scientists from Imperial College London have tested a new genetic method that distorts the sex ratio of Anopheles gambiae mosquitoes, the main transmitters of the malaria parasite, […]

New Device Detects Malaria Cheaply and Accurately


Malaria researchers at Case Western University have developed a portable malaria detector called the Rapid Assessment of Malaria device, or “RAM” for short, that uses lasers and magnets to detect malaria. Malaria parasites release iron into the blood. When a blood sample is inserted into the device, the lasers and magnets can show whether iron […]

At Least Eight U.S. Presidents had Malaria


In the U.S. today is Presidents Day, a national holiday originally intended to celebrate the birthday of George Washington, but later expanded to include honoring Abraham Lincoln and other presidents. While most people today associate malaria with developing countries — and indeed, most cases do occur in sub-Saharan Africa — the disease was quite common […]

Five Things You Never Knew about U.S. Navy Entomology


By Lt. Jen Wright and Lt. Hanayo Arimoto 1. Wait, the United States Navy has entomologists? Yes, they do! The image of an entomologist dressed in camouflage and armed with a butterfly net may seem absurd (and it is a bit of a stretch), but there are in fact 38 entomologists currently serving on active […]
