Honey Bee Losses Still a Problem in US(2/2)
Dictation & Translation:
One finding was that beekeepers who found no dead adult bees were more likely to have the most severe losses. Also, a virus called I.A.P.V., is really Israeli acute paralysis virus, with was present in almost half the colonies studied. But researchers say they do not know if this virus causes the a colony to collapse. They say the lack of affected bees to examine makes it difficult to know exactly what the new disorder is.
一项发现表明,没有找到死亡工蜂的养蜂人很可能是损失最严重的。同时,一种名为IAPV的以色列急性瘫痪病毒存在于近半数被研究的蜂群中。但是研究者称,他们不知道是否是这种病毒引起蜂群的崩塌。他们认为由于缺乏受影响蜜蜂的研究,使其难以诊断新紊乱的确切原因。
Losses in honey bee populations can result from a number of causes. A big problem, for example, is the vireo varroa mite, a deadly parasite. And experts keep looking for other answers for the current situation.
蜜蜂数量的减少可能由多种原因造成。例如,一大问题就是瓦螨,一种致死寄生虫。同时,专家仍在继续寻找现状的其他原因。
Scientists at the University of Virginia recently reported that air pollution may prevent bees from finding flowers to pollinate. They think ozone in the air is keeping bees and other pollinators from smelling the flowers. Bees feed on nectar and pollen from flowers.
佛吉尼亚大学科学家最近报道称空气污染可能阻碍蜜蜂找到花朵以授粉。他们认为,空气中的臭氧使得蜜蜂和其他授粉昆虫无法嗅到花朵。蜜蜂以花朵的花蜜和花粉为食。
Jose Fuentes and his team at Virginia studied how far the scent of the flowers travels with the wind. Before the 1800s, they say, it was more than 1,200 meters. Now, the scent can travel only about 300 meters at best. Their study is in the journal Atmospheric Environment.
Jose Fuentes和他的团队在佛吉尼亚研究花香可以随风飘到多远。他们说,在19世纪前,距离是1200米,而现在,花香只能飘散最多约300米。这一研究发表在《大气环境杂志》中。
