Interpretive Summary:

Technical Abstract: Several psyllid species such as the pear psyllid have different seasonal form characterized by different wing shape and length. Longer wing length in insects may enhance dispersal capacity, while at the same time decreasing reproductive capacity. Preliminary observations have been made of different seasonal forms, however, they have not been well documented. Asian citrus psyllids were obtained from citrus orchards from monthly aspirator collections in Alachua and Collier Co. and weekly from suction traps in Collier Co. High resolution digital photographs were obtained using a Keyence observation system with a high performance zoom lens. Using computer software, seven measurements from the wings and tibia were obtained. Principal component analysis of the measurement data was conducted to examine the effect of time of year. Additionally, location with respect to groves and height of suction trap were considered.
