الحشرات المتعددة
الحشرات طائفة (أو صف) من حيوانات لافقارية في مصلحة مفصليات الأرجل، تعتبر التصنيف الأكثر انتشارا والأوسع في مصلحة مفصليات الأرجل. تشكل الحشرات المجموعة الأكثر تنوعا من الكائنات الحية على سطح الأرض فهي تشتمل ما يكثر عن مليون نوع تم وصفها -أي أكثر من 1/2 جميع الكائنات الحية[2][3]- حيث يُقدّر عدد الفصائل الغير مصنفة بقرابة 30 مليونا، أي أنها تشكل أكثر من 90% من غير مشابه أنواع الحياة على الأرض.[4] تتواجد الحشرات في كل البيئات إلى حد ماً، لكن عدداً ضئيلاً منها قد تعَود على الحياة في البيئة المائية، أي نوع المساكن التي تتحكم فيه طائفة أخرى من مفصليات الأرجل وهي القشريات. هناك ما يقارب 5,000 نوع من اليعاسيب، 2,000 نوع من السراعيف (فرس النبي)، 20,000 نوع من الجنادب، 170,000 فصيلة من الفراش والعث، 120,000 نوع من الذباب، 82,000 نوع من البق الحقيقي، 360,000 فصيلة من الخنافس، و110,000 فصائل من النحل، الدبابير، والنمل؛ تمّ وصفها حتى هذه اللحظة. يُقدّر عدد الفصائل كلها المعروفة والغير معروفة ما بين المليونين إلى خمسين مليون، لكن الدراسات الجديدة تفترض عددا أدنى من ذلك يتراوح ما بين ستة إلى عشرة ملايين نوع.[2][5][6] يتراوح كمية الحشرات الجديدة البالغة من 0.139 ميليمترات (0.00547 إنشات) كما في اليراعة، إلى 55.5 سنتيمترات (21.9 إنشات) في الحشرة العصوية.[7] إن أثقل فصيلة حشرات تمّ إعتمادها يوما كانت الويتا العملاقة، وقد وصلت واحدة من العينات في وزنها 70 غراما (2½ أوقية)، ومن المنافسين الآخرين خنافس جالوت أو الخنافس العملاقة وغيرها من أشكال الخنافس الكبير جدا، سوى أنه ما زال من غير المؤكد أي نوع هو الأثقل وزنا.[7] تسمّى دراسة الحشرات "معرفة الحشرات" (بالإنكليزية: Entomology) المشتقة من الكلمة اليونانية "εντομον" والتي تعني كذلك "التقطيع إلى أقسام”

تاريخ الحشرات
الحشرات من أول الحيوانات التي ظهرت فوق سطح الأرض منذ نحو 435 مليون سنة وهي بذلك تعتبر أولى الحيوانات الطائرة فقد ظهرت قبل الزواحف المجنحة بنحو 204 مليون سنة. إن رابطة الحشرات بالمجموعات الأخرى من الحيوانات توجد غير جلية، وكانت تصنّف عادة بأنها من ذوي قرابة الديدان الألفية والمئوية، لكن بعض الدلائل أظهرت حديثا أنها أكثر قربا إلى القشريات من طائفة كثيرات الأرجل (أم أربع وأربعين وأقرباؤها) حيث تتشارك معها في سلف مشترك، وهكذا يمكن القول أنه استنادا لتلك النظرية فإن الحشرات بالإضافة للأنواع المتغايرة من القشريات تشكل فرعا حيويّا.[10] يُخطئ العديد من العامّة إجمالا حيث يعتقدون أن بعض أشكال المفصليات الأخرى من شاكلة الديدان المئوية، الديدان الألفية، العناكب، والعقارب هي من الحشرات بما أن شكل جسمها الخارجي متماثل، فجميعها لديها هيكل خارجي ملتحم ببعضه (وأيضاً الوضع فيما يتعلق للأنواع الأخرى من المفصليات)، سوى أنه نحو فحصها عن قرب تبدو إشارات الاختلاف الجلية وأبرزها أن تلك الأشكال لا لديها ستة أرجل كما الحشرات البالغة.[11] إن تاريخ أعراق المفصليات ما زال حتى اليوم موضوع جدل ونقاش بين العلماء. وفي عام 2008 قام الباحثون في جامعة توفتس الواقعة قرب بوسطن بالولايات المتحدة الامريكية، قاموا بكشف النقاب سادّا يعتقدون أنه أقدم أحفور لحشرة طائرة في العالم، وهي عينة تصل من السن 300 مليون سنة، أي ترجع للعصر الفحمي الحديدي.[12]

Multiple insects
Insects A variety (or row) of vertebrate animals in the interest of arthropods, is the most widespread and widespread classification in the interest of arthropods. Insects form the most diverse group of living organisms on the earth's surface. They include more than one million species described - more than 1/2 of all living organisms [2] [3] - where the number of uncultivated species is estimated at approximately 30 million, More than 90% of species are not similar to life on Earth. [4] Insects exist in all environments to a certain extent, but only a small number may return to life in the aquatic environment, the type of dwellings controlled by another range of arthropods, crustaceans. There are approximately 5,000 species of dragonflies, 2,000 species of hippopotamus, 20,000 species of grasshoppers, 170,000 species of bedding and moths, 120,000 species of flies, 82,000 species of real bugs, 360,000 species of beetles, 110,000 species of bees , Wasps, and ants; have been described so far. The number of known and unknown species is estimated at between two million and fifty million, but new studies assume a minimum of six to ten million species. [5] [6] The number of new insects of 0.139 millimeters (0.00547 inches) as in larvae ranges from 55.5 centimeters (21.9 inches) in the bony insect. [7] One of the samples was weighing 70 grams (2 أوق ounces), and the other competitors were beetles, giant beetles and other very large beetles, but it was still uncertain what kind it was. Heavier than weight. [7] The study of insects is called Entomology, derived from the Greek word εντομον, which also means "cutting into sections"

History of Insects
Insects from the first animals that appeared on the surface of the earth about 435 million years ago, which is considered the first flying animals appeared before the reptiles winged by 204 million years. The association of insects with other groups of animals is not clear, and they are usually classified as close to the Millennium and Centennial Worms, but some evidence has recently shown that they are closer to crustaceans than forty-four (and forty-one) relatives, According to this theory, insects as well as heterogeneous species of crustaceans constitute a vital branch. [10] Many others mistakenly believe that some other arthropods, such as centipede worms, worms, spiders, and scorpions, are insects because their outer bodies are symmetrical, all of which have an external structure that is intertwined (as is the case with other arthropods) However, as they are closely examined, the signs of apparent difference appear, most notably that these shapes do not have six legs as adult insects. [11] The history of the races of the arthropods is still the subject of controversy and debate among scientists. In 2008, researchers at Tufts University, near Boston, United States, unveiled what they believed to be the oldest fossils of an aircraft bug in the world, a sample of 300 million years old, dating back to the Iron Age. [12]

An ethnic historical tree of arthropods and their relatives
Leg hexagons (insects, tail stump, thoracic silverfish, conical brain)
Crustaceans (crabs, prawns, equinoxes)
Many feet are slim
Millennium Worms (Millennium Worm)
Centennial worms (one hundred or forty-four)

Anthropobacteria (spiders, scorpions and their relatives)
Widespread wing (sea scorpions: extinct)
Sword tail (Hippocampal carcinoma)
Marine Antibodies (Spiders)
Trilobites (extinct)
The oldest fossils are apparently due to an insect that was found in sediments dating to the Devonian era. The fossils reached 396 million years ago and were called the "Rani Stone" [13] in the nearby village of Rainey, which was found nearby; By the Latin name "Rhyniognatha hirsti". This type of insect has a two-part lower jaw, a phenomenon that appears to be winged insects. It is assumed that wings to insects evolved and developed at this stage, meaning that winged insects appeared earlier than this, probably in the Selorian era. [1]
The origin of the evolution of aeronautic ability to insects remains unclear, since the oldest known winged insects at present seem to have been a skilled pilot, meaning that flight evolved long before this. The few extinct insect species had an extra pair of fins attached to the first section of the chest, which made the number of pairs of wings three, and to date there is no evidence to support the saying that insects were a successful group of animals before they develop and look wings. [14]
The heterogeneous levels of insects in the late Iron Age and the Permian period included many levels still alive today, as well as the various species. During that period, some dragonfly-like species sold wings of 55 to 70 centimeters (22-28 inches) Making it larger than any insect species today. This magnitude is assumed to be due to the high oxygen content of the weather, which allowed increased breathing efficiency to match the day; it is believed that the absence of other forms of invertebrates was another reason for these insects to grow and thrive.
Most of the existing insect levels evolved during the Permian period, which began about 270 million years ago. Many of the first groups of insects were extinct during the extinction of the Permian-SnowThe largest mass extinction occurred on earth, about 252 million years ago. [15] During the Cretaceous period, the level of winged avian influenza has emerged, but has since been relatively different from that of the Earth's age during the Cinozo era. A number of other successful insect groups have evolved in conjunction with the development of flowering plants, a clear picture of shared progress, that is, when a living creature develops after another creature develops its survival. [16] Many species of insects developed during the Cenozoic period, and often well-preserved species are found in fossilized samples from the amber. The quality of these samples is comparable to that of the current species. The study of fossil insects is called "paleoentomology". Diseases caused by insects Insects and rodents cause many infectious diseases, which may lead to human death and from these diseases (typhoid - food poisoning, jaundice, rat bite fever, meningitis, cholera, pustules, dysentery, plague, child diarrhea and yellow fever. Dozens of what is harmful and this causes great damage to investment First insects and their types: - It remains from the insects what is useful and what is harmful and we will talk no less about harmful insects and how to combat them A - Insects from the inside: - Can differentiate between insect and arthropods because of Body parts are divided into three sections (head, chest, main body or abdomen) on the head. The parts of the mouth remain a life partner of the sensors. The eyes are sensitive organs that are used to touch, smell, and the eyes are either minor or complex. The brain has a nerve cord that goes beyond the lower part of the body with Glands in each section and the food that takes the insect enters into a place where it can store and adjust the gantry. The kidneys get rid of the waste that looks from the back of the body and the blood system is slight as there is walking from the blood vessels. Blood moves freely within the body and keeps moving by beating the heart. Body parts and B - How to fly insects: - Since insects do not have an internal structure of the bones in their wings. The way they fly is not the same as bird birds and bats. The muscles that occupy the wings are connected. This is similar to kayaking in a water boat and the wings' wings can be very slow, such as some butterflies (five per minute) or about 1,000 in the body. Second like Small flies and zero mites can stay in a single bird nesting in the nectar of a flower such as a humming bird, dragon flies and similar to what is in flight and can fly back also rises and falls faster and faster known insect is the Australian dragon fly and can reach speeds of 58 km / h C - the sight of insects: - is of a special type In the simple eye located in the larvae not only benefit between the differentiation between light and darkness The two complex and wide eyes are very effective for the differentiation of the movement and consists of several isolated lenses (one called a corner) and conical shape and each one of them can You see a section of the thing that looks at the mechanism, the result is a confused image of a bit cut like the Muzayek, but with the presence of these many lenses, the insect can see less movement and if you tried once to catch a fly between your hands, you know no doubt how fast eyesight. Insects that prey on their prey, such as dragonflies, may have about 30,000 monkeys in each compound eye. The eggs of the insect are inside two tubes of eggs, leading to the path of the egg. The egg moves in the tube, storing a number of food and then getting it from the male in the process of mating. It is not very similar in shape or external body. The external insect's hard body is composed of a dead cornea called the chitin. The insect builds from the waste produced by its body and supports the body as a structure, protects the insect and prevents dryness of the water without which the insect dies. Some insects can inhabit the hottest and driest parts of the earth where other animals can not live and die. D - Breathing in insects: - Insects do not resemble the human that no wind breathes the same as the reader, but when it breathes into the wind and oxygen into the tissues of the body through the pattern of overlapping tubes of the name (Tharki) and this Altraqi replace the arteries and the stubble The basic aerobic and larynx pass through the body in a ladder with small branches, respectively, such as twigs of a tree reaching the organs that take the oxygen and the air enters the thorn through a group of pores. On both sides of the body and some insects can store the wind in special bags. Carefully we can watch kind of Pulse in her stomach when you breathe and in hot weather conditions dry places close fulfilled pores do not lose the insect water body. Underwater Breathing: - Insect the water insects in two ways, some of them climb to the surface of water water bug or water beetle ascend to the surface of the water and carry with it a bubble of air to stick to the body when the plunge and many insect larvae have a breathing tube pushing the surface of the water to reach the wind and mosquito larvae on the surface The water is through its respiratory tube. The insect is from the inside. The insect is divided into three sections: the head, the chest, the main body or the abdomen. On the head, the parts of the mouth remain the life partner of the probes or the butterflies
