Locust Tiddi Dal Attack
What are Locust or Tiddi Dal?
The Locusts are the world’s oldest migratory pest.
Let’s just start from the beginning.
Locusts are large herbivorous insects that, owing to their ability to form dense and highly mobile swarms, can be serious agricultural pests.
They are species of short-horned grasshoppers that periodically form large populations in dense migratory communities, in which individuals vary from those living separately in many characteristics.
Desert locusts are a variety of grasshoppers and can fly up to 150 km daily on their way to eating anything!
As their population is rapidly growing up they become unstable and therefore the proximity to human civilizations increases leading to attacks.
Locusts migrate only during the day and in the direction of wind, and are popular for feasting on all kinds of plants and standing crops.
What is the difference between a locust and a grasshopper?
Locusts and grasshoppers are the same in appearance, but locusts may live in two separate (solitary and gregarious) states of behavior, while most grasshoppers do not.
Locusts act as individuals when the population density is small, just like grasshoppers.
However, when locust density is high, individuals undergo physiological and behavioral changes, known as phase polyphenism, forming bands of nymphs or adult swarms gregariously behaving.
They differ from ordinary grasshoppers in their ability to alter (gregarize) behavior and to form swarms which can migrate over long distances.
There is no taxonomic distinction between species of locust and of grasshopper.
Swarming activity is a response to overpopulation.
The desert shrub (Schistocerca gregaria) is the most devastating of all species of locust.
When desert locusts meet, serotonin is released by their nervous systems which causes them to attract each other, a prerequisite for swarming.
Desert Locusts live in desolate areas between West Africa and India during quiet times.

Three pests, the Italian Locust, the Moroccan Locust, and the Asian Migratory Locust, are threatening food security and livelihood in the Caucasus and Central Asia (CCA), as well as in neighboring areas of northern Afghanistan and the Southern Russian Federation.
Locusts have a high capacity to multiply, form communities, migrate over fairly wide distances (they can travel up to 150 km per day).
If ecological conditions are favorable, they can rapidly multiply and, in three months, increase some 20 times.
Original gregarious hopper bands are known as “outbreaks.”
The phenomenon is known as a “upsurge” as these join in larger groups.
Continuing agglomerations of upsurges at regional level that derive from a variety of entirely different breeding sites are known as “pests.”
Locusts need moist, sandy soil to lay eggs and fresh vegetation in order to develop hoppers into adults.India and other parts of the world: Locust attack
