展开1全部　　蜜蜂其实对农业生产不是太重要,比如我们的主食是风媒传粉的,小麦,玉米,水稻都是如此;我们的蔬菜主要是茎叶为主,瓜果豆类也有很多是自花授粉的;其三,蜜蜂的位置可以被其他昆虫所替代,蛾子,蝴蝶,食蚜蝇啥的可以来填充空缺.事实也基本如此,蜜蜂不会影响到生活必需品,但是必定会影响到很多我们熟悉的东西.1.生产成本,实际上,人工授粉的成本远比蜜蜂自然授粉的要高,至少,苹果,梨,桃子这些水果还是需要蜜蜂的,另外,葫芦科的单性的花朵更是需要蜜蜂.所以,人工授粉是可以解决问题,只是要花钱,人工成本低廉的时代已经过去了.2.我相信蜜蜂可以被替代,但是替代的过程会很长.毕竟,花朵和昆虫的匹配是数百万年演化的结果,低效率的花朵终究会淘汰的,所以,花朵依然是花朵.也许,火龙果就成了大宗水果了,食蜜鼠是它们主要的传粉者.3.不经过授粉也能结果的水果也在培育过程中,比如香蕉,这个完全可以自行结果,而部分品种的火龙果可以自花授粉了.所以,农业生产似乎并不依赖于蜜蜂.这样看来,倒是那些依赖蜜蜂传粉的野生植物面临更大的风险,但是一对一的情况比较少,所以我相信整个植物界还是会运行下去的.只是我们的餐桌上少了点蜂蜜.

　　In fact, the bees for agricultural proction is not too important, such as our staple food is anemophily, wheat, corn and rice are so; our vegetable is mainly stems and leaves, fruits and beans, there is also a lot of self pollination of bees; third, the position can be replaced by other insects, moths, butterflies, can to fill the vacancy of syrphids. What facts are basically the same, the bees do not affect the necessities of life, but it can affect many things we are familiar with the proction cost of.1., in fact, the cost of artificial pollination than natural bee pollinated by high, at least, apple, pear, peach and fruit still need these bees the simplicity of the Cucurbitaceae, flowers is the need for artificial pollination bees. So, it can solve the problem, only to spend money, low labor costs, the time has passed.2. I believe that bees can be replaced, but instead The process will be very long. After all, flowers and insects is millions of years of evolution, so the low efficiency will be eliminated, the flowers, flowers are still flowers. Perhaps, pitaya became the bulk of the fruit, the honey rat is their main pollinators.3. without pollination can result in fruit also in the process of cultivation, such as banana, the results can be completely, and some varieties of Pitaya can be self pollinated. Therefore, agricultural proction does not seem to depend on bees. It seems that it is the wild plant relies on bee pollination on more risk, but less of a situation so I believe the whole plant will still run down. But we have little honey on the table.
