The Panda Ant is a most unusual species with a lovely appearance. They look like ants but actually they belong to the wasp(黄蜂)family. The differences between the two sexes of the species are also very pronounced in both appearance and behavior. When fully grown, the male, possibly attaining a length of approximately 0. 8 centimeters, is several times larger than the female. Cute as panda ants may look, they are dangerous and capable of knocking out an animal much larger than they are with a few stings(刺).
Panda ants primarily depend on flowers sweet liquid as their food. The female panda ant often lays its eggs in a bee or wasp nest. When the young ones. hatch, they will eat their pupa(蛹)hosts.
So although a female panda ant lays approximately 2, 000 eggs a year, a considerable amount of eggs to support their survival, this species is still on the edge of dying out.
This species was first discovered in the coastal region of Central Chile in 1938.
Today, they are likely to be found in dry desert and sandy areas such as Southwestern United States and parts of Mexico.
A. It's a new fashion to raise panda ants as pets.
B. The name comes from their colors as pandas.
C. Yet young panda ants are meat-eaters.
D. No one believes the panda ant is the relative of bees.
E. Besides, the males are active at night while the females opposite.
F. Unfortunately, many panda ants are eaten for their bright colors.
G. Then little attention was given to it until recently.
Asthma(哮喘) is a long-lasting breathing disease that affects millions of Americans, many of whom are children. People who get asthma will suffer from lack of breath, difficulty in breathing or coughing--which are caused by the tightening of the muscles in airways. Untreated asthma can lead to poor lung function and death, but asthma can also be effectively controlled with proper treatments.
Research is discovering genes that contribute to the development of asthma. This development has pointed researchers to the role of indoor and outdoor pollution as environmental factors that contribute to the increased occurrence of asthma.
The Indoor Pollution
Indoor pollution has increased with the developments in building materials and in heating and air conditioning systems. In addition to poisonous gases that come from paint, other materials like dust and perfumes used in household products such as washing powder are recycled continuously through the house, winter and summer.
Unlike the days before central heating or before whole-house air conditioning, these materials and chemicals cannot get out of modern homes. Most often, they cause breathing problems in the members of the family with the least-developed autoimmune(自身免疫的) systems. Proper venting (通风) and use of environmentally-friendly building materials and carpeting can help reduce the presence of these chemicals.
The Out door pollution
Researchers have also established outdoor pollution's role as a probable cause of asthma. Asthma has been proven to result from some fuel products. Smog and the small matters carried by it have been recognized as a factor which leads to asthma since the 19th century when London saw more and more diseases in the industrial population. Industrial pollutants and other chemicals which are produced in water treatment and open treated water like that found in the swimming pools also contribute to increased cases of asthma as well as other illnesses.
Those most affected by the increase of industrial and environmental pollution are children. Although much has been done to control the levels of pollution in the US, there still remains much to do as it is a worldwide phenomenon. Until an international effort can be made to limit carbon emissions, the occurrence of environmental asthma will probably continue to increase.
