Victorian microslide of the head and antennae of a mosquito (Corethra plumicornis) by Ruichard Sutur. Mosquitos transmit diseases such as malaria, viral encephalitis, yellow fever, and filariasis. Malaria is a major health problem in Africa, Asia, India & South America. Malaria causes a severe fever & can lead to sometimes fatal complications affecting the liver, brain & blood. Preventative measures against mosquitoes are important, as the malaria parasites are developing resistance to anti-malarial drugs. Measures include using mosquito nets, protective clothing, insecticides & release of sterile males. Magnification: 10x.
