Introduction-
locust are the crop eating insects belong to the family of grasshopper. i.e family ;Acrididae .the life cycle passes through the three stage Egg,nymph,and the adult stages.they are differ in many more colour. the solitary phase has shorter wings, longer legs, and naarrow pronotium. these are consider as the danger pest because even very small one square locust swarm(Schistocerca grregria) can eat the same amount of food in one day as about 35000 people.the desert locust is consider as the most danger paste because the ability of swarms to fly rapidly across grate distance. it has two to five generations per year.locust swarms are typically in motion can cover a vast distance some species may travel 81 miles(around 130.35 kilometers) or more a day. they can stay on the air for long period off time ,regularly taking non stop trips across the seas.
Control measure for the pest-
while talking about the control measure for the pest we can adopt different measure;
1. Biological measure
while talking about the biological measure one duck can eat more then 200 locust swarm.as they are not dangerous to the animal and human beings.beside that these insect are of canibal structure if we managed to interact with at least two neighbours the insect can not reproduce
2.physical measure
while talking about the physical measure we can use the different instrument for its control foe example using bigger mosquito net in nursery ,playing a sound can also some how manage to remove the insect more ever due to the canibalism activity they are not going to stay at the particular place for longer time..
3.chemical measure
while talking about the chemical measure we cam to clouding spray with the insecticides fibornial spray as they act on the nervous system of these insect. one spray eventually stopping the insect from fee
