The BIOCAT database of introductions of insect biological control agents for the control of insect pests was updated to the end of 2010 to include 6158 introductions, using 2384 different insect biological control agents against 588 pest species in 148 countries. Of the introductions, 2007 (32.6 %) led to establishment, and 620 (10.1 %) resulted in satisfactory control being reported against 172 (29.3 %) different pest species. The number of introductions has decreased each decade since the 1970s, but in the same period a higher proportion of introductions became established and contributed to successful control of target pests, and the number of countries implementing classical biological control increased. These positive trends reflect the greater research effort now made to optimize the chances of successful outcomes and increased confidence in classical biological control as a viable pest management strategy against a backdrop of a risk-averse culture that has developed in some key countries in recent years.
