Beskrivelse

Agricultural insect pests will destroy fruits, vegetables and the plants on which they develop. The size, shape, features and other characteristics of these bugs help people to identify them. The colour of an agricultural insect pest, such as the green body and yellow stripe on the striped cucumber beetle, often gives its identity away. Different features separate some pests from others. For example, the green apple aphid has mouthparts designed to pierce and suck out juices. This aphid has recognizable cornicles that resemble two tailpipes sticking out of the rear of its abdomen. The shape of a bug's body is a great clue to what it may be. Brown marmonated stinkbugs have a body shaped like a shield, for example. This insect pest infests fruits and vegetables. Most insect pests will typically be a certain size. Sowbugs are problematic when they invade a greenhouse. These pests are usually three-quarters of an inch in length. The book will also be useful to those who are preparing for competitive examinations conducted by various Central and State Government Agencies for recruitment. Every attempt has been made to provide necessary information from the point of view of students of Agricultural Entomology, which is not available in other books.
