Migration and Meteorology


Book Description

Migrant insect pests represent a constant threat to crops and to health in many parts of the world. In Africa alone, over $100 million is spent annually on the control of a half dozen species of locust. One of the key problems in combating migrant pests is that the insect can disappear for months at a time and reappear with catastrophic effect. With the aid of aircraft and radar, it has been possible to map the movements of migrant pests. The research in this book, carried out on an international scale, has shown that migrant pests can travel longer distances than previously suspected and that their movements are related to the dynamics of the winds and weather systems. These findings throw new light on the flight behavior of the insects as well as on the ecological and evolutionary aspects of flight migration and suggest new options for controlling pests, especially locusts and grasshoppers. In surveying the achievements in this area, the author provides the biologist with an introduction to the relevant aspects of meteorology.




Weather and Desert Locusts


Book Description

"FAO and the World Meteorological Organization (WMO) collaboration on Desert Locust started in 1951. This publication is mainly intended to be used as a general reference guide for use by staff of National Locust Control Centres (NLCCs) and National Meteorological and Hydrological Services (NMHSs) of locust-affected countries. It may also be useful for anyone wanting to know more about Desert Locust and associated meteorological phenomena. The publication contains basic information on the biology and behaviour of Desert Locust, a history of locust events, weather factors that influence locust development and how to use weather information"--Publisher's description.







Monitoring of Desert Locust in Africa and Asia


Book Description

This book deals with the topic on remote sensing monitoring of desert locust in Africa and Asia. Remote sensing monitoring of the occurrence and damage of desert locust is conducted by integrating cutting-edge technologies and methods in cross-disciplinary fields in remote sensing science, geographic information science, agronomy, plant protection, agricultural meteorology, mathematics, and computer science. The main contents include spatio-temporal data analysis and processing, desert locust breeding areas monitoring, pest migration path analysis and damage monitoring. Moreover, a desert locust remote sensing monitoring system is constructed and applied in the region of Africa and Asia countries. This book not only provides technical reference for remote sensing monitoring and application of desert locust but also serves as a research reference for scholars and graduate students engaged in agricultural remote sensing, agricultural information technology, plant protection and other related field. It will help to improve remote sensing monitoring and application of desert locust.




Insect Migration


Book Description

A comprehensive account of insect migration in its ecological and evolutionary context.







New Strategies in Locust Control


Book Description

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.
