|Insects are insectivores of the insect species. From the arthropods, the insect has a fixed external cover, an external structure, a divided body, common legs, and usually the adult vertebrates, the only invertebrates that fly. The adult insect body is usually divided into three parts The head, chest, abdomen, head, three pairs of oral parts, one pair of composite eyes, three simple eyes (Ocellus), one pair of common sensory antennas, the chest divided into three parts, each pair of Legs, owns a couple m The skeletons, and the posterior molar, are associated with mating, and the outer structure consists of a solid called chitin.

Insects breathe through a complex network of airways (trachea) that are open to the outside through a series of small openings, The digestive system consists of the muscular intestines found in the chewing insects, which are not present in the absorbent insects. The simple circulatory system consists of the tubular heart, which pumps the blood forward in the head, spreads through the tissues and returns to the heart. The larvae breathe through the outer gills  General characteristics of insects Insects may be the most successful group among all animals, because of their many species and individuals, their adaptability, and their wide distribution, where wild animals predominate Currently, there are about one million species. This represents about three-quarters of the types of animals described. Insectologists estimate that the actual number of species of living insects can be up to 5-10 million. The species with the largest number of varieties, , Such as the beetle, and algeria hospitals Such as: ants, bees, wasps, and winged wings, such as real flies.  Benefits of Insecticides The importance of insects in pollinating plants can not be limited. Honeybee is one of the most important pollinators, Pollutes approximately 80% of pollination in the United States. Pollination positively affects crop productivity by about $ 20 billion a year, including fruits, vegetables, and many nuts.  Natural and biological control depends on nature's balance on parasitic activities Predators, and most of them species of impurity The researchers use this concept in biological control, and have been successful in many programs.  Importance in Nature Insects play many important roles in nature. They help bacteria, fungi and other living organisms analyze organic matter and form For example, the decomposition of the carcass, caused mainly by bacteria by fly larvae or bedding, is accelerated and the activities of these larvae that consume bacteria are followed by moth and beetle activities that analyze hair and feathers. They feed The insect pests prey on food or timber crops, whether in the field or in storage, and microorganisms transmit infections to crops, animals and humans, using pest control technologies such as: applied science for agricultural insects and forestry, Veterinary, and urban insectology.
