The ideal in locust control is preventive and proactive methods that disrupt the environment as little as possible, to make agricultural production more secure. [19] As experimental models [ edit ]

Locusts are the swarming phase of certain species of short-horned grasshoppers in the family Acrididae. These insects are usually solitary, but under certain circumstances become more abundant and change their behaviour and habits, becoming gregarious.

Oriental Literature, Applied to the Illustration of the Sacred Scriptures – especially with reference to antiquties, traditions, and manners (etc.). Longman, Hurst. p.213. Many species of army ants are widely considered to be keystone species [25] due to their important ecological role as arthropod predators [26] and due to their large number of vertebrate and invertebrate associates that rely on army ant colonies for nutrition or protection. [27] [28] [29] During their hunt, many surface-raiding army ants are accompanied by various birds, such as antbirds, thrushes, ovenbirds and wrens, which devour the insects that are flushed out by the ants, a behavior known as kleptoparasitism. [30] [31] A wide variety of arthropods including staphylinid beetles, histerid beetles, spiders, silverfish, isopods, and mites also follow colonies. [32] While some guests follow the colony emigrations on foot, [33] [34] [29] many others are phoretically transported, for example by attaching themseles on army ant workers such as the histerid beetle Nymphister kronaueri. [35] The Neotropical army ant Eciton burchellii has an estimated 350 to 500 animal associates, the most of any one species known to science. [29] Taxonomy [ edit ]

PMID 18460311.Determined movement away from the current home range - In other words, if it looks like a migration, it probably is a migration. Migrating insects move with a mission, making persistent progress away from their existing range and toward a new one. Brattström O, Bensch S, Wassenaar LI, Hobson KA, Åkesson S. Understanding the migration ecology of European red admirals Vanessa atalanta using stable isotopes. Ecography. 2008;33:720–9. A biological pesticide to control locusts was tested across Africa by a multinational team in 1997. [54] Dried fungal spores of a Metarhizium acridum sprayed in breeding areas pierce the locust exoskeleton on germination and invade the body cavity, causing death. [55] The fungus is passed from insect to insect and persists in the area, making repeated treatments unnecessary. [56] This approach to locust control was used in Tanzania in 2009 to treat around 10,000 hectares in the Iku-Katavi National Park infested with adult locusts. The outbreak was contained without harm to the local elephants, hippopotamuses, and giraffes. [46] No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions. In English, the term "locust" is used for grasshopper species that change morphologically and behaviourally on crowding, forming swarms that develop from bands of immature stages called hoppers. The change is referred to in the technical literature as "density-dependent phenotypic plasticity". a b c d Dingle, Hugh (1996). Migration: The Biology of Life on the Move.
