A historical overview of locusts
History and locusts:
He called Arabs (locusts) because it just ground are both and pasture Virkha barren do not plant them and transplant an old enmity of man as long as threatened economics and disarmament sustenance from his mouth and came to all spent very diligently in planting and plowing and spread because of famine in many parts of the land stretching from China to West Africa and from Europe to Central Africa, and was known in this regard big raids since three thousand years on North Africa and the two thousand years ago in China, except in Cyrenaica other raids thousand years ago recorded by us Bedouins.
And insect locusts known since antiquity discovered carved on the effects of Iraq, Mexico, and the effects of the ancient Egyptians fees. The ancients believed that the migration of locusts from the wrath of the gods can not be overcome, but the gods, where he was strongly believe that the time that the gods are able to yard planting so-called locusts (Snhm) in the sense devouring a word Hiroglovih.
Fees locusts and inscriptions written on many graves are conceived locusts which feeds on wheat plant as a painting on the walls of Karnak cemetery locusts devoured chrome, as well as the inscription on the walls of Thebes cemetery (in Egypt) have to stop the locusts on papyrus.
The Phoenicians fancy in insect locusts stones shiny-like porcelain in a beautiful coordinated forms of inscription, and the resistance in those times by their habits Baltaaoiv and make offerings to the gods to ward off the threat or action Tmaatm the form of contracts for men and women because they believe that bring them closer to the gods Victspon satisfaction is Phippad thereby harming all farms .
Perhaps Machohd inscribed on the walls of some of the effects Drawing man tracking Jaradah which indicates that they have resorted to resist their own hands is dependent on magic and spells. Also engraved on the lamps suggests that the ancient reached a burning fire and locusts was his way to take annihilated likely that the Assyrians and Babylonians had also reached to the study of locust numbers where we find inscriptions in the hedgehog locusts devouring insects.
Locusts time of the prophets:
Books mentioned in the era of Moses, peace be upon him that the locusts came down the country's territory with the east wind coming in and solving all boundaries and eat all the dates, leaving nothing in the green grass and all of its territory.
As mentioned that Yahya peace be upon him what appeared to call people saw him in a dress of coarse lint wrapped himself in a leather strap and fast more days and fed locusts and wild honey and calls on people to repent and prepared.
He is now the prophets ring Muhammad peace be upon him analyzes eat to express in an interview with Sheriff: Analyze your blood, liver, spleen, Mattan fish and locusts, and perhaps it is recommended to express eating food of high nutritional value they need, where the latest scientific tests proved that the locusts enters the configured value phosphorus compounds Vital known also has a value of protein and fatty substances ratios Furthermore Alflavin and riboflavin (vitamin B).
Locusts in the Qur'an:
As mentioned in the Bible cited by the Koran model expressing the widespread broadband, which rises from the ground and Vyagmurha Agsheha which is not bounded by capacity, but it does in the range. Where Allah says in Sura Moon: (Khhaa sight out of graves like locusts diffuse) and a curse and a punishment for the arrogant Allah says in Surah norms: (We sent them the flood, locusts, lice, frogs and blood verses hinges arrogant and they were folk criminals) the great truth of God.
Locusts when Bedouins:
Roy Arab poets and writers and their Mahdthohm lot about locusts and a lot of beliefs about it they supposed that the locusts arises from the sea as it was unable to cross from one side to the other of the breadth and that those seen to some extent that the raids locusts on the Arab countries had been carried out across the Arabian Gulf or across the Red Sea as they the first to indicate that the raid this insect is not continuous and annual rainfall is an important factor for the occurrence of the breed.
One of the best that was written Tomb author of the book Nihayat as he wrote: The Bedouin said about the life of the insect cycle, describing the locusts (Surat) any Badt when he came out of the eggs is (Aldby) and come out Duda closer to whiteness If zero and black and white lines colored in which he ( pool) if annexation wing it (shoulders) If the wings appeared and became red to Ghubra is the mob and so while riding Vemuj runoffs in some, if looked at in color and free yellowish differed in color is (Alkhivan) If male yellowed and blackened female then called locusts.
And locusts driven by the President to meet him Kalaskar, that flew ole whole sequence obedient and if ole inn inn Association, and locusts which almost ten Titans a face mare, and kind Phil and neck ox and issued a lion and the belly of a scorpion and suites eagle and thigh camel and a man ostrich alive and guilt.
His tract Ibn Fadlallah age of Damascus also said deceased in 1348 AD: The two types of locusts, one said to him knight who fly through the air often and the other a guy who relegated If Farragut days spring Medicine land a good soft dig Boznabha holes and put the eggs and bury and fly Vtfnyha birds and free if The squint hatchling buried appeared like little creeping things, on the face of the earth, As for the description Maihdth locust damage and famines have said Sobh TFB: that in seventy-seven hundred HJ afternoon Baham great lobster unheard parable, and spread from Mecca to Syria and bone Bmoran even eat the trees and timber The doors of houses and Maousel him from dyes, cloth, blocked the eyes of the water for fear that spoil and filled him the city and closed markets and applied the doors of shops and blocked energies and doors and attending people for Friday prayers consecrated them all and Trami on Khatib on the podium until his job for the engagement and also drag people even came out of the mosque Ikhbon it faded to the knees and the Entente of frequent Magtl him until he became the people of the country to smell the tar to cover the smell (Mayalm Lord soldiers, but it is) believed Bedouins that the cure of many diseases, including tuberculosis and tells him Ali ibn Sina (that wholesome locusts to distill urine and vaporizes him from hemorrhoids, which suites for his roasted and eaten sting Scorpio) has mastered the Arabs in preparation for Msttaba Moklhm praising advantage Anath full of eggs and they Atshehadouna Alabl burning trees to shelter near the hamlets and then sell it in the market after preparing an agent or a number.
Attention to resist the locusts:
Thus we see that since the foot and locusts always been guardians interest in different eras they took each capable recruits to work in annihilated but underdevelopment rebels gain more penalty, and higher order issued on July 16, 1891 in Egypt allows the men Administration evoke all able to work on locusts resistance. And burn the land where whitening locusts and hoeing cultivated land. The resistance has now become international. All countries threatened been stripped raids locusts of colors and creeds and worked cooperating to eliminate the locusts, and held its first agreements signed for this purpose in Rome on 31 October 1, 1920 and Angala If we consider this agreement will continue until the present day, including hold meetings, conferences, especially after taking body significant in the Food and Agriculture Organization of the United Nations, its current role in this regard.
The economic importance of the Desert Locust:
The most important types of desert locust:
The world's hundreds of species of locusts and the locust hoppers and the advantage that helps configured to withstand harsh natural conditions, Valvm strong rodent and insect feeding on the various types of plants is covered with thick whipped, and her ability to fly long distances in large groups.
There are many kinds of locusts in the world, including:
Desert Locust Schiutoaercn gragarin (peraknl) which is the most important type for the Near East.
Marrakech locusts Docieataurue mnroccanus (thunb) porsknl that appears in Europe, North Africa and some Middle East and Central Asia regions.
Lacustn migratoria migrants locust (Linneaus) different forms that live in some regions of Africa, Asia, China and the situation there is scattered in some parts of the UK.
Red locusts Nomdeacriesapteefaroiats (servillo) and lives in South Africa, Congo, Tngeniqa and around.
Brown locusts known as Locustann pardsllna (walkor) and living areas of South Africa.
Italian locusts Culliptumus sp and take some regions of southern Europe and western Asia is home to him.
Type Sehaiteceroa paranersis (Burn) which is one of the most important pests in Central America and similar type S.canoelata some regions of South America.
Locust trees Anacridium which is far from the regions of Africa, Asia and proliferate in some cases to the point of resistance and require this kind of well-known UK locusts and dense condition appears in some of the years-party Tabuk, Al-Jawf.
The seriousness of the Desert Locust:
Desert Locust is the most types of locusts dangerous for our country and the country's many other it threatens the agricultural wealth of more than one and sixty countries, representing a wide swath quarters, stretching from Morocco to India and from the coast of the Mediterranean Sea to the equator and the estimated area of this area about 11 million square miles, most of the territory of the desert and live 1/8 the world's population in this vast expanse breed this kind of locusts and spread and spread Aihd of any obstacles whether the limits of mountains or sailors.
The desert locust is an enemy that can not be for a person to feel safe voracious even disappeared for a period of short or long it constantly exists, even in small numbers to Ailtvt them, but these few numbers quickly Matzdad to be large swarms that often we see here in the Kingdom of Saudi Arabia and many other countries.
The danger of locusts in many factors, including:
First, the speed of printing locust is aligned with the surrounding environmental conditions:
As is well known, the desert locust does not only where there is soil moisture and vegetation and as always we saw the periods of the existence of desert locusts are in the same time periods of rainfall. If what I said rain and I said soil moisture in the whereabouts and reproduction of desert locusts, that prevents eggs from hatching and thereby reducing the number of locusts.
To address this situation, the Desert Locust resort to change the nature of a well-known nature of the rapid multiplication lot number to another state are less active case transforms from phase to phase immigrant solitary and thus can be kept as type in difficult periods for him.
That any unilateral condition of the desert locust, a condition used by the insect to counter the environmental conditions is maintained even as type of extinction During this case, the shape and behavior and temperament locusts completely changed from what is known as the phase-Muhajir, Masajie mentioned in detail later.
Second, the proliferation and spread of desert locusts speed:
As previously mentioned, the Desert Locust solitary but it is a case to address environmental inappropriate to multiply and spread the circumstances. If I can find the appropriate environmental conditions, especially rainfall that helps the eggs to hatch blocks and create vegetative environment needed to feed the locusts upon the locust numbers gradually increasing and becoming qualities and Tabaúah of unilateral case to migratory status.
To give an idea of the extent of this increase, the pair of desert locust immigrant usually lays 3-5 eggs a block of at least the number of eggs in each block for any produce 50 eggs from each female lobster 150-250 in the first generation and result in a second-generation 4-6 thousand locusts In the third generation 100-150 thousand locusts, and so what we realized that the average per squadron contains tens of millions of locusts, it can estimate the numerical increase in locust through not long. To implement this ideal in practice, we recall that in the period 1964-1966 and the application of this ideal in practice, we recall that the locust attack during the period from 1954 to 1962 has been uneven deeply offensive and focus and breadth of his emigration to the countries of the Middle East and East Africa and the Arabian Peninsula and, in particular, was the readiness of all States region superior and effective to reduce the severity and inventory damages in a narrower field and began the year 1961-1962 stillness period during which any swarms immigrant did not appear to these areas and has observed that the desert areas of rainfall fell on rates usual and limited presence in the some countries locusts are constantly on the lobster solitary and very limited numbers. Did not pose any danger mentions that appeared for the appropriate environmental conditions in 1967, where in many concentrated swarms appeared number in a large number of different regions and countries, and notes that it's just that locust numbers increase in the area and be appropriate air environment, the total insects begin to migrate from places proliferated to other places where you may away from the breeding places of thousands of kilometers and thus widening the scope of the injury and increasingly dangerous locusts.
Third, the ability of locusts on the rapid movement:
Desert insects of rapid movement active insects even as he is in the process nymph that have not yet growth and private suites that help locusts to fly completed Although the nymphs in the first age to be relatively slow movement, where the first phase will be limited movement in places his appearance, but the nymphs in stages these creeps quickly so it is in the last age creeps for a distance of about 5 kilometers a day and notes that are clearly in a lot of resistance areas where often the region show of nymphs in the early age so that the area look like a completely free of injury and then suddenly appear with large sets of advanced nymphs Age often coming from areas not reached the resistance operations and private mountain community.
For full insect swarms, the ability to fly long distances known and often seen swarms crossing the Red Sea from Africa to the Arabian Peninsula has some of India, Pakistan or Turkey up north.
Occurs aviation squadrons during the day until after sunset, in some cases, and then settle down swarms on the ground during the night and then continue its flight and the rate of aviation between 10 and 15 miles per hour on average and pay to immigration and affects the various factors, the most important of the heat and the sun, wind and power factors and physiological but causes This migration is not fully known, but it is not known in order to search for food often left swarms or passed on green areas and went with the wind to areas may be less greenery and drier.
Fourth: The damage caused by the Desert Locust:
Also lies the seriousness of the Desert Locust in Hrahth micro feeding on anything green, If you do not find something green, they do not even mature or the bark of fruit leaves of trees, although there are plants favored by desert locusts from other such motifs plants, but if he did not find it feeds on what happenstance of other plants.
And eat insects locust weight per day, or one that swarm of locusts, which contains millions of locusts eat daily tons of green food, which depends upon the animal and human nutrition. Causing famine and loss of many people in the Middle Ages.
It is difficult in many cases to assess and evaluate what caused one of the pests in agricultural crops from damage and if this is affordable to some extent in the case of some pests and plant diseases, it is difficult to a great extent in the case of the scourge of locusts where to fly and move and live on different plants and pastures.
However, the international statistics indicate bone losses to crops caused by this insect .. amounted to losses arising from the locust damage in the period between 1925 and 1934 more than one thousand million dollars with an average of one hundred million dollars a year, and estimated damage was revealed cultivation and groves fruit in Morocco during the 1954/1955 season as a result of the invasion of desert locust about $ 15 million.
More importantly, the cash value is the loss in human food and cattle from agricultural crops. The research proved that the locust eat per day equivalent weight, if we know that a small squadron occupies an area of no more than eight square miles containing approximately one thousand million locusts could calculate the amount of food that Ilthmha such a small squadron (average individual weight of the full locust growth around Algramen).
In Kenya in 1954 as the number of swarms that raided by about fifty squadron as weighing about 10,000 tons, she was eating about 100 thousand tons per day of plants if they are left of these swarms and that for several weeks and did not resist the equivalent of what produces a crop of 250, the amount of what they eat thousand tons of corn.
In the mid-Tanganyika in Africa and Cameroon lot of people perished of starvation as a result of the serious injuries suffered by food crops wiped out by the locusts since fifty years.
In Ethiopia, the Desert Locust in 1950 came to about three hundred thousand of the production of grain crops, more than enough to feed a million people for a whole year.
Senegal also suffered the greatest west, and India and Pakistan, the Middle maximum, and even most vulnerable nations to invade a lot of desert locust swarms devastating attack either in the near or distant era.
We recall that the raid desert locusts that occurred in 1914 Vallven Adrkoha remember how it led to the elimination of thousands of palm trees and vast areas rich green pastures and agriculture in many parts of the Arabian Peninsula and around so that you do not to Nkhalha list only after the passage of years. Palm Imad Bedouin food and a livelihood, and in those exposed conquest citrus groves in Palestine and around the badly damaged difficult appreciation Suffice it to say that his invasion of locusts in this not only by eating leaves and fruit, but the charges tree bark. And hit the cultivation of
