Grasshopper

 

The Life of Animals | Grasshopper | No coherent distinction between taxonomic species of locusts and grasshoppers, the basis for the definition of a species swarm form under appropriate intervals. In English, the term "locust" is used for the grasshopper species which are morphologically and behavioral change the movement, the formation of clouds that grow immature stages called bands hopper. Charles Valentine Riley and Norman Criddle were also involved in the development of understanding and control locusts. Research at Oxford University has discovered a swarm behavior is a response to overcrowding. This causes the locust to change color, eat much more, and much easier to raise.

Locusts in the Bible and the Qur'an, one of the biblical plagues of Egypt, where locusts ate all the crops of Egypt. In an article published in the January 30, 2009 edition of the AAAS Science Journal, Anstey, Rogers, et al. demonstrated when locusts are, their nervous systems release serotonin so attracted to each other, a prerequisite for swarming. Swarms of locusts have short antennae or antennas and auditory organs in the abdomen (posterior segment of the body). From winged adults fly in swarms, locusts may be carried by the wind hundreds of miles from their spawning grounds, landing devour all vegetation. The migratory locust (Locusta migratoria) from Europe to China, and even small swarms may cover several square miles, and weigh thousands of tons.

The largest known swarm covered 513,000 km ², comprising about 12.5 trillion insects and a weight of 27.5 million tonnes. A biological pesticide for the control of locusts in Africa has been tested by a multinational team in 1997. Dried fungal spores sprayed in breeding areas Metarhizium species pierce the locust exoskeleton on germination and penetration of the body cavity, causing death. The fungus is spread by insects and insect persists in the region, making repeated treatments unnecessary.

The extinction of the Rocky Mountain locust is a source of wonder. The international agenda is LUBILOSA promote non-chemical methods of control to find lobster. Different cultures around the world eat insects. Even Islamic law and Jewish food, eating other insects grasshoppers to eat after the ban, particularly as food for the hungry poor.

Cicada nymphs suck xylem sap of several species of trees, including oak, cypress, willow, ash and maple. Most cicadas go through a life cycle that lasts from two to five years. A predator with a shorter life cycle of at least two years with cicadas reliability of assault In Greek mythology, Tithonus eventually turns into a cicada after obtaining immortality but not eternal youth, by Zeus.

The cicada has represented insouciance from classical antiquity. Jean de La Fontaine began his collection of fables Les Fables de La Fontaine with the story La Cigale and the Ant (The Cicada and the Ant) based on one of Aesop's fables: in it the cicada spends the summer singing, the ant stores away, and went without food when the weather turns sour. In Japan, the cicada is associated with the summer season. The songs of the cicadas are often used in movies and television for the Japanese scene takes place in the summer.

Month Javanese version called Pranata cycle cicadas mangsa used as an indicator of the onset of the dry season (April-May). On the Run From now, cicadas play an important role in the books. romanticizes the insect as a creature that sings until it dies. In Tuscany, the Italian word for the cicada (Cicada) is a euphemism for "vagina", used by children (the usage is equivalent to "Fanny" in English / Australian English). In 2004, "cicada" ranked 6th in Merriam-Webster word of the year.
