The second edition takes into account developments in Integrated Pest Management (IPM) in the decade since the handbook was first published.
The handbook includes 300 new photographs, chapters on the biology and lifecycles of pests, parasitic and predatory insect controls and an enlarged section describing beneficial pathogens.
There are chapters on cropping systems and biological control in perspective. Entomologist Helyer is Fargro's field based biological control expert.
Fargro technical director Paul Sopp said: "The timing of the revision of the book could not have been better following the introduction of the Sustainable Use Directive at the beginning of 2014.
The book is available from Fargro at £41.95 (inc p&p).
