For a start, they're important in plant reproduction because they transfer pollen from one part of the plant to another and from one plant to another plant. Bees are particularly important in the pollination of many plants and trees, including fruit trees, and other insects, such as butterflies and beetles, may perform a similar function. 00:00:38,000 And insects are helpful to us in other ways too. For centuries, people have known how to make silk from the cocoon of the silkworm. 00:00:46,360 Then there are bees, and as well as producing honey, which used to be one of the only sweeteners in the past, they also produce wax, which has all sorts of uses in the home. 00:00:58,600 Some insects also kill other insects which destroy plants, like the beetle known as the ladybug, which eats harmful insects like greenfly and other aphids. 00:01:10,360 And they're important to humans in another way. There are already over a thousand species of insects which are used as food by people in different parts of the world, and there's a growing interest by nutritionists in this area. 00:01:25,900 On the other hand, many insects are certainly harmful. A swarm of insects such as locusts can completely destroy a farmer's crops in minutes. But it's not just in agriculture that they're a problem. Moths can eat so many holes in clothing that it's completely destroyed, and termites can eat away at wooden furniture and turn it into a heap of dust. 00:01:51,360 Then, of course, there are other problems. One of the reasons why insects are regarded with such distrust by the general population is because everyone nowadays knows of their ability to transmit disease. 00:02:04,660 In some cases, the insect actually needs a human host to carry out its life cycle, as with the Anopheles mosquito. 00:02:14,180 And then, although no one welcomes being bitten or stung by an insect, some people are particularly at risk when this happens because they suffer from an allergy of some kind, meaning that what would be a minor inconvenience for most people can even be life-threatening for them. 00:02:35,740 So in spite of the benefits they may bring, people have always tried to control the spread of insects, and huge industries have grown up to try to achieve this. There are various different ways by which insects can be controlled. One is by mechanical control, that is, using tools, machines, or similar devices. So for example, when gardeners or farmers use a spade or a plow to turn over the soil, this exposes those insects living in the soil to the air and means that they can be caught and eaten by birds, which benefits everyone, except for the insects who get eaten, of course. When people want to protect themselves from insects, in many parts of the world, they put nets over the windows of their houses, and the same method is used to protect people sleeping in their beds. 00:03:29,210 Then there's chemical control. This is where the big manufacturers make their money. There are various types of chemical control of insects. One is repellents, things which don't actually kill the insect but influence its behavior. They encourage the insect to stay away from you instead of landing on your skin. There are lots of different types, both natural and synthetic, and they come in different forms, such as creams and sprays. More recently, there's been a lot of interest in another type of control, biological control. 00:04:05,400 If you want to get rid of an insect by using biological control, you have to identify another creature that's the enemy of the insect in nature. So for example, a pest that was eating farmers' crops in the US was destroyed by a wasp deliberately imported from China. 00:04:25,180 Another method of insect control, which is receiving a lot of attention at present, is what's called breeding management. This involves making it impossible for the insects to reproduce and spread. In the case of insects like mosquitoes that need still water to lay their eggs, this can be achieved by proper drainage systems. 00:04:46,640 Other insects breed in areas where there is plenty of waste. So again, if this can be properly managed and cleared regularly, the insects will be unable to breed. 00:04:56,740 So those are the main means of insect control. Now finally, I'd like to look at- 00:05:05,960 That is the end of part four. You now have one minute to check your answers to part four. ## 题目与答案 ### 31.
