So far, estimates of the total number of extant species, including those not yet known to the scientific community, range from 2 million to 50 million. The latest research shows that adult modern insects are relatively small, about 600 They range in size from 1 mm cactus to 1 cm long stick insects (the heaviest recorded insect is g The giant Shiva of Oz, but other potential candidates include the giant beetle goliathus. Although no one can be sure which insect is really the heaviest, the study of insects (from Latin insects, meaning "cut into parts") is called Entomology, from Greek, which means "cut into sections.".

economy, which is a very conservative estimate John Losey, an associate professor of Entomology at Cornell University, who published the study in the current issue of Bioscience, said: "most insects tirelessly perform functions that improve our environment and lifestyle, and scientists are just beginning to understand these functions." The Xerces invertebrate conservation society in Portland, Oregon, has more than a million named insects, and possibly the same number of unidentified insects that make them the most abundant form of life on earth. The study focused on four special services provided by insects and what the cost would be if the insects disappeared: nutritious wildlife researchers looked at the annual cost of watching or hunting wild animals and how dependent they were on the food value of insects: billion dollars (billion euros of pest control insects often prey on other insects) and researchers looked at pests The amount of damage, if their predators disappear, the value of the damage: billion dollars (billion euro pollination researchers observed the value of insect free crops (excluding the value of crops pollinated by domesticated bees: 3 billion dollars (if not including dung beetles, 1 billion euro dung burial, the manure on grazing land will attract more flies and parasites, farmers must control To control these parasites, and dung beetles help to return nutrients to the soil without them, farmers will have to spend more on the value of fertilizer: million dollars (million euros) the study focused only on wild insects and did not calculate the value of commercially produced insect products, such as honey and silk Lawrence Abrahamson, who also thinks the $100 million (1 billion euro) figure is conservative, said: "most people feel sick when they think about insects, they think about mosquitoes and flies, and they don't realize that everything in life is affected by insects in some way.".

在拍苍蝇或压扁虫子之前要三思而后行：一项新的研究表明昆虫每年对美国经济的贡献超过亿美元（十亿欧元），在你拍苍蝇或压扁虫子之前要三思而后行：一项新的研究称，昆虫每年对美国经济的贡献超过亿美元（十亿欧元），这是一个非常保守的估计，主持这项研究的康奈尔大学昆虫学副教授约翰·洛西（john losey）在本期《生物科学》杂志上发表了这项研究，他说：“大多数昆虫不知疲倦地执行着改善我们环境和生活方式的功能，而科学家们才刚刚开始了解这些功能。”位于俄勒冈州波特兰市的xerces无脊椎动物保护协会有超过一百万种被命名的昆虫，并且可能有相同数量的未被确认的昆虫使它们成为地球上最丰富的生命形式。这项研究集中在昆虫提供的四种特殊服务上，以及如果昆虫消失的话，代价是什么：营养野生动物研究人员调查了每年观察或捕猎野生动物的花费，以及这些动物对昆虫的食物价值的依赖程度：亿美元（十亿欧元的虫害控制昆虫经常捕食其他昆虫研究人员观察害虫造成的损害量，如果它们的捕食者消失，将造成的损失价值：亿美元（十亿欧元授粉研究人员观察了无虫作物的价值（不包括由驯养蜜蜂授粉的作物价值：30亿美元（如果不包括粪甲虫，则为10亿欧元的粪葬，放牧地上的粪肥会吸引更多的苍蝇和寄生虫，农民必须控制这些寄生虫，而且粪甲虫有助于在没有它们的情况下将养分返回土壤，农民将不得不在肥料价值上花更多的钱：百万美元（百万欧元）这项研究只关注野生昆虫，没有计算商业化生产的昆虫产品的价值，比如蜂蜜和丝绸，纽约州立大学的昆虫学家劳伦斯·阿布拉罕森（lawrence abrahamson）也认为亿美元（10亿欧元）的数字是保守的他说：“大多数人想到昆虫就会感到恶心，想到蚊子和苍蝇，他们没有意识到生活中的一切都会以某种方式受到昆虫的影响。

满分英语范文3：有关介绍昆虫用处

You know, there are more insect species on earth than any other species of life, which is hard to imagine, but among all the animal species on earth, there are millions of insects that can live on an acre of land. Scientists have found more than a million species of insects, and they think that maybe 10 times the number has not been named. They are divided into orders, or queens The largest order is beetles (Coleoptera), with different families and different species.

In fact, one out of every four animals on earth is a beetle. Scientists estimate that the world is ants and the other is termites, which means that "social insects" may account for an incredible proportion of the total biomass of animals on this planet. Insects eat more plants than all other creatures on the planet, and they are also very much involved in the decomposition of plant and animal matter Important, without them, we would have a world full of dead plants and animals.

In addition to all this, insects are the main source of food for many other animals. Insects are incredibly adaptable creatures that have evolved to survive successfully in most environments on earth, including deserts and even Antarctica - the only place where insects are rarely found is in the ocean, Insects vary tremendously in size, shape and behavior, but they all share common characteristics.
