Just the mention of locusts can strike fear into the heart of a farmer. Locust plagues wreak havoc on crops and have been the cause of millions of people going hungry. This book examines the life of a locust and what happens to cause a swarm to form. Locust swarms can contain trillions of insects and cover hundreds of miles of land, so locust control is essential to countries dependent on crops. This book offers both historical and scientific information on locusts and impresses just how detrimental these creatures can be.

Pay attention to these insects on the move locusts! Usually, locusts live alone. When there is lots of food, the locust population grows. But when the weather turns dry and grasses die, the locusts are forced to live close together, and they go through amazing changes. Their colors become brighter, and their eyes become larger. They fly off in great swarms searching for food. Millions of locusts might land in a farmer's field and have a feast. When nothing green is left, the swarm flies off again. After they finally run out of food, the locusts separate and change again. In this exciting book, you can learn what makes locusts similar to and different from other insects. Close-up photographs and diagrams reveal extraordinary details about locusts' bodies, both inside and out. This book contains hands-on activities that help you understand how far locusts jump and how they make sounds. Learn more about this member of nature's fascinating Insect World!

In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.
