Maintaining access to safe and healthy food for a rapidly growing world population is a major challenge for the
21st century. Greenhouse cropping systems offer a great opportunity to this challenge. Biological pest control
has become the most important pillar in Integrated Pest Management (IPM) to achieve this goal. Unfortunately,
the availability of natural enemies in Saudi Arabia are subjected to regulations and delivery times are long.
This hinders adequate response to pests and to the quality of natural enemies. The mean pests in greenhouse
crops in Saudi Arabia are identified as Tuta absoluta, Thrips, Whiteflies, Aphids, Spider mites and Russet
mites. During field trips around Riyadh several potential natural enemies against these pests were identified
which include Orius sp., two species of the genus Coccinella and Chrysoperla sp.
