Global malaria prevention and control programs depend almost exclusively on the use of long-lasting insecticidal nets (LLINs), manufactured with materials into which insecticide is incorporated or bound in some fashion to the fibers. They are meant to provide personal protection against malaria by serving as a physical barrier between human and vector and by repelling… Continue reading Durability of long-lasting insecticidal nets (LLINs) in Ethiopia
Studies of the fine-scale spatial epidemiology of malaria consistently identify malaria hotspots, comprising clusters of homesteads at high transmission intensity. These hotspots sustain transmission, and may be targeted by malaria-control programs. Here we describe the spatial relationship between the location of Anopheles larval sites and human malaria infection in a cohort study of 642 children,… Continue reading Wind direction and proximity to larval sites determines malaria risk in Kilifi District in Kenya.
Malaria vectors have spread southward expansion by 4.7 kilometers (nearly 3 miles) every year, and risen 6.5 meters (21.3 feet) in elevation each year. That’s further and faster than previous estimates which reported that across the board, terrestrial species were moving poleward by 1.7 kilometers (1.05 miles) a year and upslope by 1.1 meters (3.6 feet)… Continue reading Malaria Vectors Expanding Their Territory Almost 5 Km Annually
Las chinches de cama han vivido en nuestras casas durante miles de años. Este pequeño insecto hemíptero es un ectoparásito que se alimenta de sangre humana y de otros animales como aves de corral, murciélagos o roedores. Hay dos especies que afectan a humanos: Cimex lectularius, más cosmopolita, y C. hemipterus más frecuente en trópicos… Continue reading ¿Por qué han regresado los chinches de cama y cómo los podemos combatir?
A fascinating interview with Ronald Sherman, M.D., M.Sc., DTM&H regarding the use of fly maggots as therapy for specific condition recently published in Entomology Today provides an interesting glance at this fascinating and seldom used tool. The full report can be found at: Entomological Medicine: How One Scientist is Working to Bring Maggot Therapy Into… Continue reading The return of Myiasis?

Anyone who’s ever felt the subtle sting of a mosquito bite and delivered a sharp slap to the affected area has probably wondered: How are mosquitoes so good at hunting down humans? The moment we step outside, it seems, they arrive en masse, ready to suck nutrient-rich blood from their next victim. Researchers used gene-editing technology in an attempt to… Continue reading How mosquitoes find a victim.
On this three-week course, you’ll examine the rise of insecticide resistant mosquitoes and the resultant need for a new approach in the world’s fight against malaria. https://www.futurelearn.com/courses/the-resistant-mosquito-staying-ahead-of-the-game-in-the-fight-against-malaria
The global burden of dengue is high, but poorly quantified and likely under-reported. Almost three million disability-adjusted life-years (DALYs) were lost to dengue in 2017: an over 100% increase since 1990 Using the methods of the Global Burden of Diseases, Injuries and Risk Factors study, Zeng et al. characterized the dengue burden in 195 countries… Continue reading Global, regional, and national dengue burden from 1990 to 2017
Much has been said about the reduction of insect populations. The lack of insects on a windshield or flying around artificial light at night leaves many to believe that the “insect apocalypse” is happening. If so, a significant reduction of pollinators could spell disaster. A look at insects may have been evolving to avoid artificial… Continue reading Is the “insect apocalypse” happening?
