Technical Abstract: The Asian Citrus psyllid, Diaphorina citri, as a vector of the bacteria causing citrus greening, is considered one of the most important citrus pests globally. While surveillance of these insects if critical for effective disease surveillance and management, trapping of these insects is limited to inefficient non-specific methods. A better understanding of the visual system of these insects could provide the basis for enhanced sensitivity by surveillance traps. Using electroretinograms, the spectral sensitivities of male and female citrus psyllids were determined. Regions of maximal sensitivity were matched by theoretical pigment absorption curves to determine the composition of photopigments present. These data in conjunction with behavioral studies can provide the basis for more effective surveillance traps.
