WASHINGTON - Wild bees and the flowers they pollinate are disappearing together in Britain and the Netherlands, researchers reported on Thursday.
世界80%以上的杏仁树都生长在加利福尼亚,为了给它们授粉,大约7000个种植户租用了全美国230万个商用蜂房中的140万个蜂房。
More than 80% of the world’s almonds are grown in California and, to pollinate them, the 7, 000 or so growers hire about 1.4m of America’s 2.3m commercial hives.

摘要本文研究了为小蜜蜂授粉的蜜蜂种类,以及它们的生长和衰退规律。
This article deals with the species of bees pollinating Amomum compactum, along with the laws governing their growth and decline.
今天,大约有20,000种蜜蜂被确认为授粉者,它们促进了地球上大多数开花植物(约有235,000种)的健康和安乐。
Today, some 20, 000 species of bees are recognised pollinators, contributing to the health and wellbeing of the majority of the 235, 000 species of flowering plants on the planet.
这些勤劳的小昆虫是世界上最大的授粉者,在它们为蜂巢收集花蜜的过程中,带着花粉尘掠过一个又一个花朵。
These industrious little insects are the world's greatest pollinators, carrying a dusting of pollen from flower to flower as they gather nectar for their hives.
第一个诱使动物替它们串花授粉的并不是开花植物。
Flowering plants were not the first to seduce animals into spreading their pollen for them.
它们为动物提供食物,还能为植物授粉。
这两种文化通常无法象它们应该的那样交叉授粉,尽管可能有的特别机会。
These two cultures are generally failing to cross-pollinate like they should, despite potentially extraordinary opportunities.
欧洲蜜蜂早在四百年前就输入了美洲大陆,自从上世纪五十年代这些蜜蜂被驯化为授粉工具之后,人们就开始用车装载着它们沿着高速公路来回奔波。
The European honeybee, first imported to the Colonies some 400 years ago, has been the domesticated pollinator workhorse in the U.S. since people began trucking them up and down highways in the 1950s.
如果这些植物是“表亲”或者“血亲”的话,它们会以相同的速率成熟,因为这是“成熟缓慢的植物增进交叉授粉机会”的一个方法。
If the plants are "Cousins" or "siblings," they'd likely mature at the same rate because it's a way for "slowly maturing plants to improve their chances of cross-pollination."
蜜蜂看不见红色,但它们可以看见其它鲜艳的颜色。红色花卉通常依靠鸟类、蝴蝶、蝙蝠和风媒进行授粉,而不是靠蜜蜂。
Bees can't see the color red, but they can see all other bright colors. Red flowers are usually pollinated by birds, butterflies, bats, and wind, rather than bees.

授粉就是由蜜蜂将花粉从一个花朵转移到另一个花朵上,如此帮助它们生长成为另一个同类的花朵。
Pollination is the transfer by bees of a pollen from a flower to another flower thus helping them grow into another same kind of a flower.
他可以实现它们间的杂交授粉。
大部分蟑螂喜欢更为传统的户外昆虫生活,它们可以帮助回收腐烂植被,帮植物授粉,甚至在一些情况下还会捕食害虫。
Most roaches prefer a more conventional insect life outdoors, where they help to recycle decaying vegetation, pollinate plants, and in some cases even prey on more harmful insects.
它们保持正常的自花授粉繁殖。
一提起蜜蜂,人们很容易想起它们在田间飞来飞去、勤劳地进行授粉的画面。
When bees are mentioned, people would easily relate them to be the hard-working creature who always fly in the field busying transferring pollen.
