(ZEGV), Zika virus, as well as Plasmodium gallinaceum and Plasmodium lophurae. This mosquito also mechanically transmits some veterinary diseases. In 1952 Fenner et al., found it transmitting the myxoma virus between rabbits and in 2001 Chihota et al., the lumpy skin disease virus between cattle. The yellow fever mosquito can contribute to the spread of reticular cell sarcoma among Syrian hamsters. Bite prevention methods The Centers for Disease Control and Prevention traveler's page on preventing dengue fever suggests using mosquito repellents that contain DEET (N, N-diethylmetatoluamide, 20% to 30%). It also suggests: Although Aedes aegypti mosquitoes most commonly feed at dusk and dawn, indoors, in shady areas, or when the weather is cloudy, "they can bite and spread infection all year long and at any time of day." Once a week, scrub off eggs sticking to wet containers, seal and/or discard them. The mosquitoes prefer to breed in areas of stagnant water, such as flower vases, uncovered barrels, buckets, and discarded tires, but the most dangerous areas are wet shower floors and toilet tanks, as they allow the mosquitos to breed in the residence. Research has shown that certain chemicals emanating from bacteria in water containers stimulate the female mosquitoes to lay their eggs. They are particularly motivated to lay eggs in water containers that have the correct amounts of specific fatty acids associated with bacteria involved in the degradation of leaves and other organic matter in water. The chemicals associated with the microbial stew are far more stimulating to discerning female mosquitoes than plain or filtered water in which the bacteria once lived. Wear long-sleeved clothing and long pants when outdoors during the day and evening. Use mosquito netting over the bed if the bedroom is not air conditioned or screened, and for additional protection, treat the mosquito netting with the insecticide permethrin. Insect repellents containing DEET (particularly concentrated products) or p-menthane-3,8-diol (from lemon eucalyptus) were effective in repelling Ae. aegypti mosquitoes, while others were less effective or ineffective in a scientific study. The Centers for Disease Control and Prevention article on "Protection against Mosquitoes, Ticks, & Other Arthropods" notes that "Studies suggest that concentrations of DEET above approximately 50% do not offer a marked increase in protection time against mosquitoes; DEET efficacy tends to plateau at a concentration of approximately 50%". Other insect repellents recommended by the CDC include Picaridin (KBR 3023/icaridin), IR3535, and 2-undecanone. Population control efforts
