Helmut van Emden & Richard Harrington 
Aphids as Crop Pests 

Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Helmut van Emden is Emeritus Professor of Horticulture at the University of Reading, UK. He has researched on aphids for over 50 years and has wide international experience, including in the tropics.

Richard Harrington retired in 2015 as Head of the Rothamsted Insect Survey, with which he worked for 36 years on aphid monitoring and forecasting. He led the EU project ‘EXAMINE’ (Exploitation of Aphid Monitoring In Europe) which brought together colleagues involved in aphid monitoring throughout Europe and beyond.
