Page 7 The Shoreline June, 1999 Mosquito Questions Answered History: The Asian Tiger mosquito was brought to the U.S. breeding in a load of used tires shipped fronn Japan in the 1980's. Once established in the U.S. the Asian Tiger quickly spread throughout the southeast and central states. It has become our most common pest mosquito species. The Asian Tiger is not easily controlled. Spraying is ineffective as the adult mosquito hides under leaves where pesticide droplets can't reach her. Source reduction and larvaciding are the only effective management tools. Mosquito dunks, or granules (available at hardware stores) placed in breeding places will kill the larva before they can become biting adults. Removing breeding opportunities is the best and least expensive method of control. She bites anytime, day or night and lays her eggs just above the waterline in artificial or natural containers. Eggs are not harmed by dry or cold weather and when wetted by rainfall will soon hatch. Even a teaspoon of water can harbor hundreds of larvae. Undergoing complete metamorphosis, the larvae have four instars then pupate before emerging as adults. Description: The Asian Tiger \s about 1/8 inch in length. Its coloration is black with white banding on the legs and body. A distinct silver-white stripe runs down the Asian Tiger's head and back. These unique patterns identify the Tiger from other species. Disease Risl: The Asian Tiger is shown in lab research to harbor many viruses & filaria (ie; canine heartworm). In the U.S. there is concern that the Asian Tiger will become competent of transmitting encephalitis and play a part in the importing of dengue fever. How to Defeat the Asian Tiger: The Asian mosquito doesn't fly far from its breeding place. If adults are found, water-filled containers must be nearby. The best way to control this mosquito is Source Reduction: eliminate containers that hold water.
