Transient vectors (those that do not reproduce on the disease-affected crop) can cause difficulties in assessing potential crop losses to disease. A probability model is presented that relates density of transient vectors (over time) to disease incidence in the crop at harvest. The application of the model is illustrated with reference to Bemisia tabaci (Gennadius), an insect that vectors infectious virus yellow in lettuce in the Imperial Valley of California.
