Transcript of Tiger Mosquitoes
The Asian Tiger Mosquito first entered the United States from shipments of used tires from Southern Asia in the mid-1980s. Those shipments were to counties in California. The used tires contained many Asian Tiger Mosquito eggs. The people of California learned this when Tiger Mosquitoes were spotted in the same counties where the shipments were dropped off. They were recently introduced during the summer of 2001, from containerized shipments from China of the plant known as Lucky Bamboo. They were found to contain Tiger Mosquitoes. They were found during an inspection by officers on arrival at Los Angeles, California. The mosquitoes laid their eggs inside the Lucky Bamboo. They were introduced because the U.S had ordered Lucky Bamboo from China and the Mosquitoes were on board with the Bamboo. They started spreading from California throughout the U.S. Since they were introduced twice, they were able to increase their own population in the U.S. They can be found today in coast lands, forests, wetlands, urban areas, and inside tree holes. Distribution By: Afzal, Ivan, and Vernon Tiger Mosquitoes Resources Adults are known as Asian Tiger Mosquitoes because of their patterns on their black bodies with white stripes. Also, there is a single white stripe down their back. They are called Asian Tiger Mosquitoes because they are native to northern and southern Asia. Their body length is about 5 mm(1/8 in.) to 1 in. long. The are classified as invertebrates because they do not have backbones. Tiger mosquitoes are small, fragile insects with slender bodies, one pair of narrow wings, and three pairs of long legs. Females have a long and slender proboscis, which is used to bite and draw blood of animals. Males feed of of nectar from plants. The adult Tiger Mosquito flight range is very small. (Aedes Albopictus) Effects on People and Animals People and animals interact with the species because Tiger Mosquitoes suck the blood out of them. Sometimes, this can cause rashes and the bite can be very irritating because the bite will be itchy. The more you scratch it, it will become worse. The consequences for humans and animals are, if the Tiger Mosquito that has bitten you and it's a vector of a disease, you can receive that disease. Some of the diseases they spread are the West Nile Virus, Yellow Fever, and Malaria. Description Effects on Ecosystem Changes that have observed in the ecosystem since Tiger Mosquitoes have been introduced are decrease of the animals that live there due to the spread of diseases and there was a new food source for small animals. People who live around the area are affected the same way animals are affected. Tiger Mosquitoes are animals that are and bad to the environment. Tiger mosquitoes are good for the ecosystem, because they're a great food source for small animals like birds, bats, frogs, toads, fish, salamanders, and other insects. They affect other animals in the ecosystem, because they spread diseases which can kill other animals. Domestic animals like dogs, farm animals like horses, are majorly affected by Tiger Mosquitoes. Issues for the Future The Life Stages of a Tiger Mosquito The Asian Tiger Mosquito has four stages throughout its life cycle. The four stages are egg, larva, pupa and adult. The first three stages occur in water or the adaptive climate the egg was laid in. The adult is the free flying insect that feeds on humans, other animals, and the nectar of plants. Reasons for Success Tiger Mosquitoes were successful in their new environment because they didn't have any competitors in the food chain. Since no animal ate them, they were able to reproduce quickly before they had predators. This is how they have been able to survive ever since they have been introduced. When they were first introduced, they didn't play a role with it's ecosystem until the were added to the food chain. It took time for them to adapt and gain natural predators. When they were first introduced they reproduced enough to keep their species alive. They were also successful in their environment because they were able to adapt to the environment and climates really fast. Physical Control: Recently there are new traps being developed. One of the latest traps invented is the scent trap. These traps produce a smell similar to a human body in an upward air current. This attracts the Tiger Mosquitoes. Then they are lured to the scent. At last, the Tiger Mosquitoes die when they are captured. Another type of physical control is Mosquito repellant. You must be cautious where you spray it. It works because they give off chemicals that Tiger Mosquitoes avoid. The repellant keeps them away and if they get too close they die. Preventative Control: Other attempts to stop the growth and spread of the Tiger Mosquitoes are, several countries in South America have inspected embargoes on used tire importations, in an attempt to prevent mosquitoes to spread. They clean the tires to make sure there are no eggs. Other countries in Asia, Europe, and Australia also do this to their shipments. The trade off to these options are that they can be expensive and you are making the Tiger Mosquitoes closer to extinction. When they are extinct, some animals might not be able to find food.
