Saliva
for mosquitoes to get food in the blood, it must avoid breastfeeding physiological responses. Like all insects, mosquitoes, blood is an effective mechanism to prevent blood clotting system with a mixture of saliva secreted proteins of them. Mosquito saliva affect the contraction of the blood vessels, blood coagulation, platelet aggregation, angiogenesis, and immune and inflammatory create universal saliva arthropod hematophagous. At least one antic lotting of antiplatelet and substance of vasodilators saliva of mosquitoes also contains enzymes that help in feeding sugar and antibiotics to control bacterial growth in sugar composition of mosquito saliva. relatively simple, as it usually is less than 20 prominent protein. Despite significant advances in the knowledge of these molecules and their role successfully in blood feeding recently, scientists still can not work for more than half of the molecules found in arthropod saliva of the program. development trends of drug antic lotting such as coagulation inhibitors and dilators capillary that may be beneficial for heart disease and stroke,
it is now well known that feeding ticks, sandflies and recently. mosquitoes will have the ability to adjust. The response of the immune system of the animal (host) where they eat. The presence of this activity in vector saliva. Reflection of the inherent nature of overlapping and interconnected host hemostasis and inflammation. The immune response and the real needs of the protected area to prevent them from interfering with feeding success. Mechanism for alteration of mosquito saliva-induced immune response is unclear. However, the data has become an increasingly convinced that such effects occur, and first described in the salivary factors that directly inhibits TNF-A release. But no antigen was histamine secretion from activated cells. Trial by Cross et al (1994) demonstrated the integration of Ae aegypti mosquito saliva into naïve cultures led to the suppression of interleukin (IL) -2 and IFN-Y production while. cytokines IL-4 and IL-5 are affected by mosquito saliva. The proliferation of cells in response to IL-2 can be reduced significantly by pre-treatment of cells with SGE respectively activated splenocytes isolated from mice fed upon by both Ae. Aegypti and Cx pipiens mosquitoes produce a significantly higher level of IL-4 and IL-10 together with the production of suppressing IFN-Y unexpected changes in the expression of cytokines is. observed in splenocytes to 10 days after the mosquito introduce natural feeding of mosquitoes can. Has a strong, sustainable and systemic immune responses of
T. Cell populations are sensitive to pluck suppression of mosquito saliva showed a mortality increase and decrease in the division. Parallel operation by Wasserman and colleagues (2004) demonstrated that T- and B-cell proliferation was inhibited in a dose-dependent manner at concentrations as low as 1/7 of saliva in a single mosquito Depinay and (. 2005) found that the suppression of T cell responses specific antibody mediated by mosquito saliva and dependent cells and IL-10 expression,
a recent study showed mosquito saliva can also decrease the expression of interferon -α /. β at the beginning of a mosquito-borne viral infection of the participation of interferons (IFN) in recovering from a viral infection has been demonstrated in vivo by treatment. Prevention of disease and the effects of administration of IFN reaction or IFN, and recent research suggests that mosquito saliva exacerbates West Nile virus infected mosquitoes transmit the virus, as well as others.

egg development and digestion in blood
female mosquitoes using two different food sources. They need sugar for energy, which is taken from sources such as nectar, and they need blood as a source of protein for egg development. The bite is risky and may be difficult to find a mosquito host blood as much as possible when they have a chance, but it creates another problem.
When the mosquito drinking sugar solution is applied to the crop. Plants can release sugar in the stomach that is desired. At the same time, the stomach is not full of sugar solution which will prevent mosquito blood meals are likely if
the blood is directed straight into the stomach of the mosquito. In species that feed on the blood of mammals or birds hosts with hypertension, the selection of a mosquito feeds on the blood pressure in the gut fill quickly. If instead Tbiug feeding one of the apartheid order to catch the turkey and mosquitoes can not withdraw it until the pressure is dilated bowel rest and mosquitoes die. Mosquitoes are not harmed The mosquitoes will be withdrawn and a filling fills up the stomach lining to shed peritrophic membrane that surrounds the blood membrane which makes blood separated from the other in the stomach. However, as with any other insect species that survive on a purely liquid diet induces many Hemiptera notably mosquitoes, many adults are fractional excretion of water an unpleasant, even while they eat. As long as they are not disturbed, allow mosquitoes to continue feeding until they have accumulated a diet filled with solid foods. As a result, mosquitoes comprising the blood can continue to absorb blood sugar, even when the food is digested slowly over several days. When the blood in the stomach, the stomach of a woman protein synthesis. Degrading enzymes, proteins, amino acids independently. These are used as building blocks for the synthesis of egg yolk proteins
in Anopheles stephensi Liston trypsin activity is restricted entirely to the left after gastric no trypsin activity occurs before eating blood. However, the increase in activity up to 30 hours after eating. It '
