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.

Insect pests are becoming a problem of ever-more biblical proportions. This new textbook collates a series of selected papers that attempt to address various fundamental components of area-wide insect pest control. Of special interest are the numerous papers on pilot and operational programs that pay special attention to practical problems encountered during program implementation. It’s a compilation of more than 60 papers authored by experts from more than 30 countries.

A devastating desert locust upsurge has spread across parts of the Near East, the Greater Horn of Africa and South West Asia in 2020–2021, posing risks to livelihoods and food security in the region. FAO's intervention has been to curb the spread of desert locust, safeguarding livelihoods and providing recovery, and coordinating and preparing the rapid surge support. This report showcases the second phase of the real-time evaluation, in which the following issues have been investigated: i) country level results from case studies; ii) management and operational processes; and iii) extent to which lessons from countries and regions are transferred to other contexts. Six priority areas emerged from this process: i) country level training and capacity development; ii) national locust control and architecture; iii) procurement; iv) pesticide management; v) livelihoods support; and vi) innovation and learning.
