Sensitization mechanism antenna effect

The mechanism for sensitized luminescence using the antenna effect is shown schematically in Fig. 2. 

The exact mechanism is still a matter for debate, but most repellent chemicals are thought to work by interfering with the mosquito s homing system. A mosquito s antennae contain a number of chemical receptors which are sensitive to different compounds, such as COg and octenol exhaled by animals (see p381) and lactic acid, which naturally evaporates from the skin of warm-blooded animals. The receptors allow the mosquitoes to follow these emissions back to their source, and hence home in on their prey. However, when a repellent is applied to the skin, it evaporates and masks these scents. Thus, the mosquito is effectively blinded . More recent research has shown that...
