The simple paired-treatment experiments are used to determine whether yield losses occur at a naturally occurring level of pest intensity. Such experiments are carried out in a single field over which the pest intensity is often assumed to be of the same order of magnitude between replicate treatments. Multiple treatment experiments take the paired treatment approach one stage further by increasing the number of treatments, with each treatment representing a different intensity of pest insects. A multiple treatment yield loss experiment involves a more complex experimental design, the principles of which are pertinent to many aspects of field trials methodology in pest management.
