6. Locusts - a messenger of hunger

Asian or migratory locust (Locusta migratoria). Every inhabitant associated with the green world of plants and animals living on them has seen locusts. Remember the story "The Green Filly"? This is one of the 2 life forms of locust - solitary. A harmless green filly. Is it so?

Locusts are large insects, 3-6 cm long, resembling grasshoppers. A distinctive feature is the presence of a curved sharp keel on the pronotum, powerful jaws. The front wings of the locust are dense with brownish-brown spots, the rear wings are delicate transparent with a yellowish, sometimes greenish tint. Depending on the amount of food and the state of the external environment, the adult locust can lead a solitary lifestyle (green filly) or gregarious (brownish individuals). In the solitary phase, locusts practically do not harm plants.

Why are locusts dangerous?

Locusts are omnivorous pests with the highest feeding activity in the early morning and evening hours, when there is no heat peak. During the gregarious period of life, the locust forms huge swarms (bands) of adults from the united aggregations of larvae. One gregarious individual eats 200-500 g of plants with different densities of vegetative and generative organs (leaves, flowers, young branches, stems, fruits).

The locust devours everything on its way. A swarm of locusts is capable of simultaneously occupying from 2.0 to 20.0 and more thousand hectares of land and flying, feeding on the way, up to 300, and with a favorable wind and up to 1000 km per day, leaving bare ground with separately sticking out remnants of woody shoots and stems plants.

The gregarious way of life of the locust can last for several years, gradually dying out and moving again to a solitary form of existence. The interval between epiphytoties is on average 10-12 years.

Locust control methods

Agrotechnical

  • In areas prone to locust attack, a late digging of the summer cottage or adjacent area is necessary.
  • In early autumn digging, spring deep harrowing is recommended, which contributes to damage to nests (egg-pods) with pest eggs.
  • Unused areas should be tinned to prevent egg-laying and egg-laying by female locusts.

Chemical

  • With a large accumulation of locust larvae in certain areas, it is treated with chemicals Decis-extra, Karate, Confidor, Image, which lasts up to 30 days.
  • Systemic insecticide Clotiamet-VDG provides plant protection against locust for up to 3 weeks.
  • Insecticide Gladiator-EC is good at killing larvae and adult locusts. Doses of the drug vary with the age of the locust.
  • Damilin is a long-acting insecticide.

In general, all chemicals can be used against locusts as against the Colorado potato beetle.
