Interpretive Summary: Presented here is a protocol to determine the number of thrips and minute pirate bug predators in crops over multiple dates in field experiments. Also illustrated is how to determine the efficacy of management tactics against thrips and evaluate the benefits of predation by minute pirate bugs. These techniques will be helpful for extension and research personnel.

Technical Abstract: The western flower thrips, Frankliniella occidentalis, is a polyphagous pest that has been spread worldwide. Minute pirate bugs are the most important worldwide predators of thrips. Flower samples taken at least weekly are needed to understand predator-prey dynamics. A sampling protocol for the flowers of fruiting vegetables and companion plants to estimate the densities of individual thrips and minute pirate bug species are demonstrated. Representative data illustrates how the protocol is used to determine the efficacy of management tactics over time and how to evaluate the benefits of predation by minute pirate bugs. The sampling protocol is similarly adaptable to sampling thrips and minute pirate bugs in other plant species hosts.
