Mediterranean Fruit Fly (Diptera: Tephritidae): Distance/Response Curves to Trimedlure to Measure Trapping Efficiency

Abstract

The probability of capture of male Mediterranean fruit flies, Ceratitis capitata (Wiedemann), by trimedlure in a trap is described by an exponential curve derived with a good fit from 22 replications at each of six different distances. Not all males are responsive on any one day. There is a high probability of capture of nearby males which decreases rapidly to only a few percent at 240 m (800 ft).
