In a research, scientists from Australia have found that practice of overgrazing not only affects the land and cattle adversely but also invites locusts by manifold.

The scientists suggest that many locusts avoid the grasses full of nutrition and prefer less nutrient grass. Therefore, if overgrazing is controlled, it could lead to many benefits including the drop in the possibility of locust plagues.

"Some locusts thrive on vegetation grown in degraded soils, our research fits well with long-term sustainability goals for managing land and, in particular, the production of sheep", told Arianne Cease, a Biologist from Sydney University. She added that there is a significant improvement in the growth of Sheep if they feed on vegetation grown in well nutrient soils.

Cease has earlier worked on the Mongolian locust found in North-East China; she told that overgrazing indirectly encourages the locusts' outbreak, as the plants are left with very less amount of nitrogen.

After heavy grazing, there is a little amount of organic nitrogen left on top of soil. Thus, the plants growing on such soil offer as high-carbohydrate and low protein diet and researches have confirmed that locusts are at their best when take low-protein diet.

The main focus area of Cease's study now is to find the relation between land use and quality of vegetation and its effect on the locusts in Australia.
