<p> Molecular gut-content analysis is an established and increasingly important approach for tracking arthropod predation in the field. Previously, it is difficult to know what hemipteran generalist predators consume because there are no pieces of prey in their gut that could be identified following dissection. However, DNA of the prey item is present in a predator's gut for a certain amount of time. In order to relate the proportion of predator individuals found to contain pest DNA to the number of pests eaten over a given time period, it is necessary to determine how long pest DNA can be detected after predation has occurred. Studies were done to explore consumption of <i>Geocoris </i> and <i>Nabis</i> with green peach aphids and Colorado potato beetles.</p>
