描写蜜蜂的作文英语篇一:

Honeybees are in danger worldwide.

Their homes -- known as "colonies" -- are suffering from what scientists call colony Collapse Disorder.

Scientists have linked the disorder to infections from harmful microorganisms and pesticides -- products meant to kill other insects.

Researchers also have blamed a sharp drop in the honeybee population to loss of the bees' natural habitat.

Polish researchers are working on ways to save honeybees. One of the diseases that affect honeybee colonies in Poland is nosemosis, also called nosema. It is a common fungi-based disease that affects adult bees.

Aneta Ptaszynska is a researcher with Maria Curie-Sklodowska University.

"Infected worker bees live for a very short time in the summer, about eight to 12 days, while they normally live 36 days. So the productivity of the whole bee family decreases and bees also have problems with passing (the) winter..."

Scientists believe some pesticides weaken the bees' natural resistance against disease. This makes it difficult for them to fight parasitic organisms. After eating food or drinking water containing pesticides, the bees begin to act strangely and soon die.

Scientists believe nosema is one of the main reasons the number of bees has dropped by 50 percent in Poland over the past 15 years.

Polish scientists say they have found a natural substance in flowers that is more than 90 percent effective in saving bees. They have created a drug from it. The drug is now being tested.

Scientists are warning that insecticides designed to kill mosquitoes carrying the Zika virus can also harm bees. They say such products should be used in affected areas only when it is dark -- after bees are asleep. And they say only chemicals that kill the mosquito larvae should be used.

Michael Steinkampf is a beekeeper.

"This particular strain is very toxic to mosquito larva but when it's put in the water it doesn't hurt the bees at all."

全球蜜蜂面临危机。

蜜蜂的家园—“蜂群”正遭受着一种名为“蜂群崩溃综合症”的疾病。

科学家们认为,蜂群崩溃综合症与有害微生物及杀虫剂污染有关。

研究者们也认为蜜蜂栖息地缩小是蜜蜂数量锐减的原因。

波兰研究人员正努力拯救蜜蜂。孢子虫病是影响波兰蜂群的一大疾病。这是一种常见的危害成年蜂的真菌类疾病。

阿内塔·帕特司纳斯卡是居里夫人大学的研究人员。

“夏季,被感染的工蜂存活的时间较短,大约为8到12天,而正常情况下可以存活36天。因此,整个蜂群的产量会骤降,而蜜蜂也很难熬过冬天。”

科学家们认为,有些杀虫剂削弱了蜜蜂的疾病抵抗力。因此,蜜蜂很难抵抗寄生物感染。蜜蜂接触含有杀虫剂的食物或水源后,行为开始出现反常,随后死亡。

科学家们表示,过去15年里,波兰蜜蜂数量下降了50%,而孢子虫病是主因。

波兰科学家表示,他们在花朵中发现一种自然物质,该物质挽救蜜蜂的有效率高达90%。他们还借此研制出一种新的杀虫剂。目前该类药品正在检测中。

科学家们警告称,某些杀虫剂虽可杀死携带寨卡病毒的蚊虫,但同样也会伤害蜜蜂。他们表示,此类产品只能等天黑蜜蜂们睡着后在疫区使用。他们表示,应该只使用能够杀害蚊虫幼体的杀虫剂。

迈克尔·斯泰因康福是一名蜂农。

“这种特殊杀虫剂对蚊虫幼体来说是剧毒,但把它放在水中后就不会对蜜蜂造成伤害了。”
