Insects
Insects fall into biology - in terms of classification - under the kingdom of animals, and they belong to a group called arthropods, meaning that they do not have a spine or any type of bone to support their bodies, but rather they have soft bodies covered by relatively solid scales, which are arthropods, and their bodies In general, it consists of three parts: the head, chest, and abdomen, and it often has three pairs of legs on either side of its body. Insects are one of the most diverse and widespread groups of living organisms, and this feature of wide spread is due to several characteristics that insects possess, the most important of which is their enormous ability to adapt in all environments and continents (except for the frozen continent), and to this day nearly a million species have been discovered and classified. Between beetles, grasshoppers, bees, wasps, bedding, moths, flies, dragonflies, mantises and others, the total number of insects on Earth (known and not yet known) ranges from five to ten million species, which may take a long time to be discovered all of them.

The relationship of insects to humans
Scientifically, insects are classified into hundreds and thousands of species according to their anatomy, appearance, and their adaptation to their environment, but for the ordinary non-specialist person, it is possible to classify these organisms between insects harmful to humans, insects useful to him, insects that do not affect him, and in fact insects (as a species) Complete) do not harm the environment; Because it is a natural part of the ecosystem and plays a role in its balance, its damages are equal to its benefits to the environment, and if all insects disappear from the earth, the environment will change radically and many other organisms will disappear. However, man is interested in combating certain types of insects because of their negative effects on Economy and health.

The person who works in agriculture is often interested in the impact of insects on his life more than others, for several reasons, the most important of which is that insects multiply more in agricultural areas, which makes them both share the same environment, and therefore he needs to study its effect on it in many ways, the first of which is its effect on his agricultural production He works with him throughout the year, and here the harmful insects are considered the position of the pest for him, because their presence can damage the entire crop in a very short time, such as if a swarm of locusts attack the fields, or small insects destroy the plant by parasitizing and devouring it, and from Here, combating them becomes a basic necessity to maintain agricultural production. In fact, some studies estimate that insects consume or destroy 10% of agricultural crops in advanced industrialized countries, and about 25% in developing countries. Insects may sometimes be the cause of the transmission of dangerous diseases that affect human health, and may lead to the death of large numbers of people, and then it becomes a very dangerous pest.



Peaceful insects
Peaceful insects are those species that do not cause harm to humans or their food, and they may be beneficial to the environment and important to them, or they may simply not have any effect on human beings. Insects are creatures that contribute to the natural balance of ecosystems. Although they have major negative effects on plants and agricultural crops, they also play a fundamental role in nature.



The cycle of natural elements
Insects help complete the natural cycle of chemicals, as they work to saturate the soil with oxygen, retain rainwater, and help to turn the soil more than earthworms themselves (by digging burrows to live in or bury their eggs in), and they also contribute to increasing the distribution of nutrients. - Like minerals and others - in the environment. In addition to that, insects prevent the accumulation of large quantities of animal waste and manure, as they work to break it up and analyze it by the fungi and bacteria that spread them, and if it were not for this activity, the majority of agricultural lands and open prairies would have become covered with livestock and other animal manure, and in fact, some farmers import In Australia and the United States, dung beetles from East Africa help to eliminate the waste from their herds. شركة رش مبيدات بالخبر

Transfer of pollen grains
One of the most important natural functions that beneficial insects perform for humans is spreading pollen grains and transferring them between flowers, and the necessity for that lies in pollinating and multiplying plants and spreading in nature, as many fruit trees need these insects to produce their fruits, including oranges, apples, plums, strawberries and pears, And grapes. Many types of insects contribute substantially to the transport of pollen, the most prominent of which are bees, wasps, butterflies, moths and flies. Insects may also pollinate M....
