Is the “insect apocalypse” happening?

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?

New malaria vector could bring malaria back to Africa

Scientists say an invasive mosquito species was likely responsible for a large outbreak of malaria in Ethiopia earlier this year By MARIA CHENG AP Scientists say an invasive mosquito species was likely responsible for a large malaria outbreak in Ethiopia earlier this year, a finding that experts called a worrying sign that progress against the disease is… Continue reading New malaria vector could bring malaria back to Africa

About the Mosquito

Here’s a short video loaded with information about mosquitoes. The language is a bit off, but the information presented is very good.

A fascinating look at insect flight

Flying is a complicated event that can be translated as physics in motion. And it gets exponentially more complicated for tiny insects. A fascinating look at how one particular group of insects manages to take flight is provided in: https://www.nature.com/articles/d41586-022-00144-0

The rise of mosquito-borne diseases.

According to the United Nations, since 2007, more people globally were living in cities than at any other time in history. In Africa, projections show that by 2030 the urban population will rise to 824 million – an increase of almost 25 percent compared with today and by 2035, more people on the continent will be… Continue reading The rise of mosquito-borne diseases.

Multi-insecticide resistant malaria vectors in the field remain susceptible to malathion, despite the presence of Ace1 point mutations

Insecticide resistance in mosquitoes threatens the success of malaria vector control. Identifying the underlying mechanisms enables optimization of strategies. The molecular mechanisms of insecticide resistance in three mosquito field populations from southern Côte d’Ivoire was investigated. https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1009963

Benin, Uganda and Rwanda eliminate human African trypanosomiasis as a public health problem

Human African trypanosomiasis (HAT), otherwise known as sleeping sickness, is a life-threatening disease that afflicts poor rural populations. Carried by tsetse flies, the disease has long been a curse for communities in West, Central and East Africa, where two different variants of the disease were rife. Now, countries and communities are fighting back with vigour… Continue reading Benin, Uganda and Rwanda eliminate human African trypanosomiasis as a public health problem

Insecticide treated bed nets contribute to resistance in bed bug populations

The use of insecticidal bed nets (IBNs) to prevent mosquito bites in malaria-endemic communities can result in resistance developing in secondary pests like bed bugs, according to research published in Parasites and Vectors. Decreased efficacy against bed bugs and other non-mosquito pests may result in misuse of both mosquito adulticides and bed nets, hampering efforts to stop… Continue reading Insecticide treated bed nets contribute to resistance in bed bug populations

Enfermedades infecciosas empeoran debido al cambio climático

Más del 58 por ciento de las enfermedades humanas causadas por patógenos, como el dengue, la hepatitis, la neumonía, la malaria y el zika se han visto agravadas por el cambio climático, según un estudio publicado el 8 de agosto en Nature Climate Change. Los hallazgos se producen en momentos que muchas regiones del mundo atraviesan sequías y olas de… Continue reading Enfermedades infecciosas empeoran debido al cambio climático
