《昆虫记》这本书使我十分着迷，读了它我才知道，原来昆虫世界有这么多的奥秘，我知道了：凌晨，蝉是怎样脱壳；屎壳螂是如何滚粪球的；蚂蚁是怎样去吃蚜虫的分泌物。还弄清了：“螟蛉之子”是错误的，蜂抓青虫不是当成自己的儿子养，而是为自己的后代安排食物。第一次读《昆虫记》，不知怎么的它就吸引了我。这是一部描述昆虫们生育、劳作、狩猎与死亡的科普书，平实的文字，清新自然；幽默的叙述，惹人捧腹……人性化的虫子们翩然登场，多么奇异、有趣的故事啊！法布尔的《昆虫记》，让我没有梦幻感，那些具体而详细的文字，不时让我感觉到放大镜、潮湿、星辰，还有虫子气味的存在，仿佛置身于现场一样。被我忽视太久了的昆虫的身影，及它们嚣张的鸣叫，一下子聚拢过来，我屏住呼吸，然后，凭它们穿透了我心灵的幽暗。是法布尔，让我看到了昆虫跟我们人类在生与死，劳动与掠夺等许多问题上都有着惊人的相似。《昆虫记》不是作家创造出来的世界，它不同于小说，它们是最基本的事实！是法布尔生活的每一天每一夜，是独自的，安静的，几乎与世隔绝的寂寞与艰辛。我仰起了头，这一刻，我非常想仰起我的头，像仰望星空一样，来对待昆虫们存在的奥秘。它使我第一次进入了一个生动的昆虫世界。于是，我接着往下看《昆虫记》。接着往下看，《昆虫记》是一个个有趣的故事：“螳螂是一种十分凶残的动物，然而在它刚刚拥有生命的初期，也会牺牲在个头儿最小的蚂蚁的魔爪下。”蜘蛛织网，“即使用了圆规、尺子之类的工具，也没有一个设计家能画出一个比这更规范的网来”，丰富的故事情节使我浮想联翩。看着看着，这些虫子们渐渐地清晰起来，我思考着：如果我们环境保护，不环境污染，这些虫子是不是还会在呢？现在的环境恶化，又是不是在以后还会有呢？我仔细地想了一想这彼此之间的关系，这一次的阅读，《昆虫记》为我打开了一扇全新的门。当我继续阅读《昆虫记》时，我看到法布尔细致入微地观察毛虫的旅行，我看到他不顾危险捕捉黄蜂，我看到他大胆假设、谨慎实验、反复推敲实验过程与数据，一步一步推断高鼻蜂毒针的作用时间与效果，萤的捕食过程，捕蝇蜂处理猎物的方法，孔雀蛾的远距离联络……一次实验失败了，他收集数据、分析原因，转身又设计下一次。严谨的实验方法，大胆的质疑精神，勤勉的作风。这一次，我感觉到了 “科学精神”及其博大精深的内涵。昆虫学家法布尔以人性关照虫性，千辛万苦写出传世巨著《昆虫记》，为人间留下一座富含知识、趣味、美感和思想的散文宝藏。它行文生动活泼，语调轻松诙谐，充满了盎然的情趣。在作者的笔下，杨柳天牛像个吝啬鬼，身穿一件似乎“缺了布料”的短身燕尾礼服；小甲虫“为它的后代作出无私的奉献，为儿女操碎了心”；而被毒蜘蛛咬伤的小麻雀，也会“愉快地进食，如果我们喂食动作慢了，他甚至会像婴儿般哭闹”。多么可爱的小生灵！难怪鲁迅把《昆虫记》奉为“讲昆虫生活”的楷模。我叹服法布尔为探索大自然付出的精神，让我感受到了昆虫与环境息息相关，又让我感受到了作者的独具匠心和细微的观察。《昆虫记》让我眼界开阔了，看待问题的角度不一样了，理解问题的深度也将超越以往。我觉得《昆虫记》是值得一生阅读的好书，我想无论是谁，只要认真地阅读一下《昆虫记》，读出滋味，读出感想，一定可以知道的更多。

昆虫的营养价值：昆虫是人类向自然界摄取蛋白质的途径之一，据记载：从古时，在人民生活困难的时候，就主要使用昆虫。目前在世界贫穷的国家：如非洲，尼泊尔，埃塞俄比亚等均以昆虫和草根为生，昆虫已成为他们的重要摄取脂肪，蛋白质的途径。从营养价值来看，昆虫含有丰富的蛋白质，干虫体的含量高达百分之30～百分之70而且由20多种重要氨基酸组成，含有人体与动物无法合成的8种必需氨基酸和儿童必须的2种氨基酸，干的蝉含有百分之72，蚂蚁含百分之42，黄蜂含百分之81蟋蟀含百分之65，并且昆虫还含有丰富的脂肪，糖类，矿物质，维生素，水。其脂肪中百分之85为软脂肪和不饱和脂肪酸，所以易被人体所吸收。丰富的食用昆虫资源：由于昆虫数量多，繁殖多，可以在残酷的环境下生存，所以即使大量捕捉也很难造成生态破坏，并且很多国家的养虫业很发达。我国蚕业，蝗虫资源都很丰富，并且有些地方也有使用它们的习惯。我国曾多次向外国出口蝗虫，蚕蛹等～～～～国外也以开办：苍蝇工厂，蚯蚓工厂等，利用其产卵多，生命力强等特点向大众提供大量蛋白质。全世界约有3000种昆虫可以食用，我国约有800种。由于昆虫的食物转换率高，食用3kg植物蛋白可以换1kg昆虫蛋白，而牛需要8kg植物蛋白才可以换1kg动物蛋白，羊则10kg植物蛋白才可以换1kg动物蛋白所以因为昆虫繁殖快，数量多，生命力强等特点，昆虫业有很好的发展前景。使用昆虫的利用情况：在现实社会中，昆虫不仅还可以用作食物，还可以用做医药，许多药如：僵蚕，九香虫，蝉蜕，龙凤，冬虫夏草等既是可以治疗某些疾病，还可以对人生体进行滋补。在古代，昆虫就在人们的食谱上曾有过重要的地位，至今，很多国家还保留着这些习惯。墨西哥的外号叫“昆虫之乡”，有370多种昆虫可以作为佳肴，列入品牌的有60多种，所以墨西哥每年因这个原因吸引了世界很多游客。利用昆虫或其他产品为原料作为饮料：蜂蜜在很多人群众多很流行，老人小孩都很爱喝，在爱喝的同时还可以对胃和其他器官进行护理。我国在3000多年前就有养蜂的习惯，并且一直流传到现在，蜜蜂也是授粉昆虫，所以对农业也有很好的促进。我国不仅是养蜂，食用蜂蜜最多的国家，也是饲养蜂蜜最多的国家，大约拥有600多万箱蜂群。而且在国内外也有很多人提取蜂毒来治疗人体的风湿等疾病。所以，发展昆虫业是很好的一项事业。

法布尔懂得了两件事。第一件，偷鸟蛋是件残忍的事。第二件，鸟兽同人类一样，它们各自都有各自的名字，各自的尊严。于是，他开始把田野上的，森林中的各种动物都当成了自己的朋友。在野外建立一个试验室。假装帮助同伴，偷取现成的东西。蝉的视力在地上很好，在地下很弱，几乎全靠触觉。螳螂常常半身直起，立在太阳灼烧的青草上，态度很庄严，宽阔的、轻纱般的薄翼，如面膜似的拖曳着，前腿形状如臂，伸向半空，好像是在祈祷……那种貌似真诚的态度是骗人的，高举着的似乎是在祈祷的手臂，其实是最可怕的利刃，无论什么东西经过它的身边，它便立刻原形毕露，用它的凶器加以捕杀。它真是凶猛如饿虎，残忍如妖魔，它是专食活的动物的。看来，在它温柔的面纱下，隐藏着十分吓人的杀气。猛禽只是外表凶悍。但是真正具有胆识的勇气的人是小小的蚱蜢。在遇到危险时，它的胆量是过人的。放到透明的钟罩里细细欣赏。不懂你说的什么！法布尔把他们装到一个纸袋里，带到很远的地方，但他们还是飞回来了。雌性的萤不怎么引人注意，它对于飞行的快乐，却是一无所知的。真的有些可怜，它不能完全懂得世界上还有自由飞行这种快乐可以享受。它终身都处于幼虫的状态，也就是说处于一种不完全的形状，似乎永远也长不大。小斑纹蟀是啥？意大利蟋蟀的外壳不是黑色的，它的体型不那样粗笨。金步甲与朗格多克蝎。小飞蝇将卵产在隧蜂的蜜中，将这个家洗劫一空，抢夺得最好的食物，化蛆成蛹，第一代的隧蜂幼虫就都死了。蝎子为卵胎生。你有几个地方是错别字，以至于我不知道是什么。答案就这么多了。

研究昆虫控制的文章Athenix and Monsanto Announce Collaboration on Research for Insect ControlRESEARCH TRIANGLE PARK， NC and ST LOUIS， June 20 /PRNewswire-FirstCall/ -- Athenix C and Monsanto Company today announced they have entered into a three-year research collaboration for insect control on a key class of insects that affects a number of Monsanto's major crops of Financial terms of the agreement were not "We are pleased to work with the market leader in crop genetics to bring our technical capabilities to commercialization，" said Mike Koziel， chief executive officer for A "Working with Monsanto to discover novel genes for controlling insect pests increases options for farmers and allows Athenix to demonstrate the power of its integrated discovery platforms for new biotech traits，" said Nick Duck， vice president of research at A Athenix will apply its expertise in microbial screening and genomics to facilitate gene discovery intended to help protect crops such as cotton， soybeans and corn against a common class of insects known as H Hemipteran insects include Lygus， a pest of cotton， and stinkbug， a pest of "This collaboration will work to offer an essential benefit to our farmer customers by providing insect protection in crops such as corn， cotton and soybeans against the piercing and sucking Insect tolerant crops allow growers to spray less pesticide， making their operations more efficient and at the same time stewarding the environment，" said Robert T Fraley， PD， Monsanto executive vice president and chief technology "We're excited to collaborate with Athenix to help broaden grower's options for insect " About Athenix: Athenix is a leading biotechnology company that develops novel products and technologies for agricultural and industrial applications， including biofuels and Athenix has established an outstanding intellectual property portfolio and market access ability around enhanced plants， microbes， genes， enzymes， and processes with emphasis on two major markets: 1) novel agricultural traits for growers such as insect resistance， nematode resistance， herbicide tolerance， and their use for the crop production industry; and 2) the discovery of genes and proteins for use in the sustainable chemical industry with a focus on biofuels like ethanol and other natural Biological control of locusts New weapons for old enemiesDuring the 1988 desert locust plague， swarms crossed the Atlantic from Mauritania to the Caribbean， flying 5 000 kilometres in 10 Scientists were stumped because migrating swarms normally come down to rest every But locusts can’t swim， so how could it be? It turned out that the swarms were coming down at sea – on any ships they could find， but also in the water The first ones in all drowned but their corpses made rafts for the other ones to rest Since the dawn of agriculture more than 10 000 years ago mankind has had to deal with a resourceful and fearless enemy， Schistocerca gregaria， the desert Normally loners， every so often these natives of the deserts from West Africa to India turn into vast， voracious swarms that leave hunger and poverty behind them wherever they Throughout history， farmers and governments have made attempts to repel the bands and swarms of locusts by collecting insects， creating noise， making smoke and burying and burning the But all of this had little With swarms sometimes extending for hundreds of kilometres， and containing billions of individuals， they conquered by sheer force of Health concernsIt has long puzzled humans where these animals came from and where they Only in the mid-20th century was it realized that the light brown solitary desert-dwelling insect was the same species as the red and yellow locusts of the Only when its biology was understood and chemical pesticides and aerial spraying became available a few decades ago， could efforts be made to control the But large-scale pesticide use also raised real concerns for human health and the On the seventh-floor Emergency Centre for Locust Operations (ECLO) at FAO Headquarters in Rome， Keith Cressman， FAO's locust forecaster， checks current environmental conditions and locust population data from the three computer screens on his The last big locust upsurge ended early in 2005 and the current alert level is green or The experts at FAO’s ECLO are readying to fight the next round in the age-old battle against locusts – wherever and whenever that may “The next time，” says Cressman， “we’ll fight with new tools” New bio-control agents Recent advances in biological control research， coupled with improved surveillance and intelligence， could make a big difference when the next round in the battle is Such products could make it possible to sharply reduce the amount of chemical pesticides One promising avenue is research currently under way at the International Centre for Insect Physiology and Ecology (ICIPE) in N An ICIPE team headed by a Zanzibar-born chemical ecologist， Ahmed Hassanali， has identified and synthesized a specific locust pheromone， or chemical signal， that can be used against young locusts with devastating Phenylacetonitrile， or PAN for short， normally governs swarming behaviour in adult males who also use it to warn other males to leave them in peace while they But， Hassanali found it has startlingly different results on juvenile wingless locusts， known as Hopper bandsJust as adult locusts form swarms， hoppers will， given the right conditions， stop behaving as individuals and line up in marauding bands up to 5 kilometres They are only slightly less voracious than adults， who eat their own weight of food every In three separate field trials – the most recent in Sudan last year – Hassanali’s team showed that even minute doses of PAN could stop hopper bands dead in their tracks and make them break PAN caused the insects to resume solitary Confused and disoriented， some lost their appetite altogether， while others turned cannibal and ate one Any survivors were easy prey for What makes PAN particularly attractive is that the dose needed is only a fraction – typically less than 10 millilitres per hectare – of the quantities of chemical or biological This translates into substantially lower costs – 50 cents per hectare as opposed to US$12 for chemical pesticides and $15-20 for other bio-control That is clearly a major consideration in the countries in the front line – many of them among the world’s Green Muscle A different， but also highly effective biological approach is Green Muscle ®， a bio-pesticide developed by the International Institute for Tropical Agriculture’s biological control centre in Cotonou， Benin， and manufactured in South A Green Muscle ® contains spores of the naturally occurring fungus Metarhizium anisopliae acridum， which germinate on the skin of locusts and penetrate through their The fungus then destroys the locust's tissues from the This is definitely not good news for locusts， but the fungus has no effect on other life A product similar to Green Muscle ® is already successfully used in Australia， but the latter's introduction in Africa and Asia is being slowed by several These include a need for further large-scale trials， official approval of the product in several countries， and a relatively short shelf-life in its normal ready-to-spray liquid One drawback is that it takes days to kill the It is also relatively expensive and large-scale production would need to be A solution would be to store the product in powder form and dilute it just before Hassanali’s team has also shown that， if used in combination with a small amount of PAN， only a quarter of the normal dose of Green Muscle ® is Insect Growth RegulatorsAlso being readied for the modern locust fighter’s armoury is a class of products known as Insect Growth Regulators， or IGRs， which influence the ability of hoppers to moult and grow They have no direct toxic effects on IGRs are effective for several weeks after application and can be used in so-called barrier In this method only narrow swathes of the product are applied， perpendicular to the direction of the marching hopper Only 10 percent of the amount used in blanket treatment is After marching over one or two barriers the hoppers absorb enough product to die while As with PAN and Green Muscle ®， however， IGRs need to be aimed at locusts at an early stage in their lives， before they take to the That， in turn， requires an advanced level of surveillance and intelligence-gathering to make sure that any locust concentrations are nipped in the eLocust2Although back at ECLO Keith Cressman has satellites， computers and mathematical models at his disposal， the weak link in the chain has been the time it takes to get good information from the The mobile ground teams whose job it is to keep tabs on locust populations have to work in some of the world’s remotest， hottest and sometimes (for environmental and security reasons) most hostile A week or more might go by before a report from， say， the central Sahara， reached Cressman’s By that time the locusts – “They don’t need visas，” he says – would quite likely have moved to another country or continent This will soon change Field teams are now being issued with special hand-held devices to record vital locust and environmental data and relay them back to their own headquarters and on to Rome in real Developed by the French Space Agency CNES， the eLocust2 device is able to bounce the information off communications satellites and have the data arrive in the National Locust Control Centre in the affected country a few minutes later， from where they are passed on to Cressman for In case of unusually heavy hopper concentrations， immediate action can be taken to make sure that the locusts never grow old enough to Back to the fieldWriting in Science magazine， locust expert Martin Enserink gave the following graphic description of a locust population gone out of control:“On a beautiful November morning (in Morocco) it’s clear， even from afar， that something’s terribly wrong with the trees around this tiny They are covered with a pinkish-red gloss， as if their leaves were changing "As you get closer， the hue becomes a wriggling mass; a giant cap of insects on every tree， devouring the tiny Get closer still and you’ll hear a soft drizzle: the steady stream of locust droppings falling to the ” Such nightmare visions， and locust plagues with them， may one day be a thing of the
