From VOA Learning English, this is the Agriculture Report.

New studies have found that a chemical commonly used to fight plant disease is harming honeybees. Experts say the chemical may be partly to blame for the widespread loss of honeybees in the United States.

The insects are important to farmers. When a honeybee lands on a flower in plant, pollen sticks to its legs. When the bee lands on another flower, some of the pollen falls off and fertilizes the second plant.

The act of pollination is responsible for many fruits, vegetables, nuts and other crops. Yet about 30 percent of honeybees in the United States and other areas have died in recent years.

Dennis VanEngelsdorp is a researcher at the University of Maryland. He wants to learn why so many bees are dying.

"The number of colonies that die every winter has been one in three. So on average 30 percent of the colonies have died every winter over the last six winters. And that's an astronomical number."

His research team examined the pollen grain that honeybees carried to their homes. They found that the pollen contained high levels of 35 different pesticides, chemicals use to protect plants. They also found that bees eating some fungicides of biological organisms became infected with a deadly micro-organism called Nosema.

Yet fungicides are necessary to use for agricultural purposes in the United States. Mike Leggett studies pesticide for the pest management industry group -- CropLife America.

"Fungicides are used, and have been used, pretty broadly, for centuries, for protection of plants from plant disease."

He says that many of the pesticide found in the pollen examined by Dennis VanEngelsdorp actually protect bees from Nosema.

Maryland farmer and beekeeper Keith Ohlinger has watched many of his bees die every winter. Mr Ohlinger thinks widespread bee death is result of several things happening at once. But he does not feel sure that pesticides are a part of the problem.

"What I felt it was, was a compilation of a lot of little things. I didn't feel that there was probably one smoking gun. But there's a division there, some people feel that it is just one thing. Maybe I'm just not educated enough, I don't know, but my view is, if you can take a bath in it, it's probably safe. And I don't know many of the things that they're putting out right now that anybody would come out of a bath in for any length of time and go, ‘Wow, that was great, I feel much better!'"

Honeybees are important to agriculture. This makes the search for an answer to their death especially urgent for Mr VanEngelsdorp's team.

As he knows, one in every three bites of food we eat is somehow pollinated by honeybees.

And that's the Agriculture Report from VOA Learning English.

這里是美國(guó)之音慢速英語(yǔ)農(nóng)業(yè)報(bào)道。

New studies have found that a chemical commonly used to fight plant disease is harming honeybees. Experts say the chemical may be partly to blame for the widespread loss of honeybees in the United States.

新的研究發(fā)現(xiàn),通常用來(lái)對(duì)抗作物病害的化學(xué)品會(huì)傷害蜜蜂。專(zhuān)家們表示,化學(xué)品可能是美國(guó)蜜蜂大范圍死亡的部分原因。

The insects are important to farmers. When a honeybee lands on a flower in plant, pollen sticks to its legs. When the bee lands on another flower, some of the pollen falls off and fertilizes the second plant.

蜜蜂對(duì)農(nóng)民們來(lái)說(shuō)非常重要。當(dāng)蜜蜂落在作物的花上時(shí),花粉粘到它們的腿上。當(dāng)這只蜜蜂落到另一朵花上時(shí),一些花粉掉落,給這第二株作物授粉。

The act of pollination is responsible for many fruits, vegetables, nuts and other crops. Yet about 30 percent of honeybees in the United States and other areas have died in recent years.

授粉行為發(fā)生在很多水果、蔬菜、堅(jiān)果和其它作物身上。然而近年來(lái),美國(guó)和其它地方有大約30%的蜜蜂死了。

Dennis VanEngelsdorp is a researcher at the University of Maryland. He wants to learn why so many bees are dying.

丹尼斯·范恩格斯德多普(Dennis VanEngelsdorp)是馬里蘭大學(xué)的一名研究人員。他想要搞明白為什么這么多蜜蜂死亡。

"The number of colonies that die every winter has been one in three. So on average 30 percent of the colonies have died every winter over the last six winters. And that's an astronomical number."

他說(shuō),“每年冬天都有1/3的蜂群死亡。過(guò)去六年,每年冬天平均有30%的蜂群死亡。這是個(gè)天文數(shù)字。”

His research team examined the pollen grain that honeybees carried to their homes. They found that the pollen contained high levels of 35 different pesticides, chemicals use to protect plants. They also found that bees eating some fungicides of biological organisms became infected with a deadly micro-organism called Nosema.

他的研究小組檢查了蜜蜂帶回蜂巢的花粉粒。他們發(fā)現(xiàn),花粉含有35種不同的用于保護(hù)作物的農(nóng)藥和化學(xué)品,且含量特別高。他們還發(fā)現(xiàn),蜜蜂吃了一些生物體殺菌劑,感染上被稱(chēng)為微孢子蟲(chóng)的致命微生物菌。

Yet fungicides are necessary to use for agricultural purposes in the United States. Mike Leggett studies pesticide for the pest management industry group -- CropLife America.

然而殺菌劑在美國(guó)農(nóng)業(yè)用途的應(yīng)用是非常必要的。邁克·萊格特(Mike Leggett)在蟲(chóng)害管理行業(yè)機(jī)構(gòu)--美國(guó)作物生命協(xié)會(huì)研究農(nóng)藥。

"Fungicides are used, and have been used, pretty broadly, for centuries, for protection of plants from plant disease."

他說(shuō),“幾個(gè)世紀(jì)以來(lái),殺菌劑在防止植物受病害方面應(yīng)用得相當(dāng)廣泛。”

He says that many of the pesticide found in the pollen examined by Dennis VanEngelsdorp actually protect bees from Nosema.

他表示,許多范恩格斯德多普檢測(cè)的花粉中發(fā)現(xiàn)的農(nóng)藥實(shí)際上可以防止蜜蜂感染微孢子蟲(chóng)。

Maryland farmer and beekeeper Keith Ohlinger has watched many of his bees die every winter. Mr Ohlinger thinks widespread bee death is result of several things happening at once. But he does not feel sure that pesticides are a part of the problem.

馬里蘭州的農(nóng)民和養(yǎng)蜂人基思·歐靈格(Keith Ohlinger)每年冬天都看到自己很多蜜蜂死亡。歐靈格先生認(rèn)為蜜蜂大范圍死亡是幾大因素同時(shí)作用的結(jié)果。但他不認(rèn)為農(nóng)藥是問(wèn)題的一部分。

"What I felt it was, was a compilation of a lot of little things. I didn't feel that there was probably one smoking gun. But there's a division there, some people feel that it is just one thing. Maybe I'm just not educated enough, I don't know, but my view is, if you can take a bath in it, it's probably safe. And I don't know many of the things that they're putting out right now that anybody would come out of a bath in for any length of time and go, ‘Wow, that was great, I feel much better!'"

他說(shuō),“我認(rèn)為它是很多小東西匯集而成。我不認(rèn)為有確鑿證據(jù)。但目前有分歧,一些人認(rèn)為只有一個(gè)原因。也許是我沒(méi)受到足夠的教育,我也不知道這些。但是我的觀點(diǎn)是,如果你能在里面游泳,它可能就是安全的。而我不知道他們目前推出的很多東西,會(huì)不會(huì)有人進(jìn)去游足夠長(zhǎng)時(shí)間,然后出來(lái)說(shuō),‘哇,很好,我感覺(jué)好多了。’”

Honeybees are important to agriculture. This makes the search for an answer to their death especially urgent for Mr VanEngelsdorp's team.

蜜蜂對(duì)農(nóng)業(yè)非常重要。這使得尋找它們死亡的答案對(duì)范恩格斯德多普的團(tuán)隊(duì)來(lái)說(shuō)非常迫切。

As he knows, one in every three bites of food we eat is somehow pollinated by honeybees.

如他所知,我們所食用的1/3的食品某種程度上是由蜜蜂授粉。
