Scouting Citrus for Pests - Page 29
Psyllids or jumping plant lice belong to a family (psyllidae) of aphid-like insects. However, they are different from aphids by the presence of jumping legs, the absence of cornicles, presence of eggs and winged males in all generations. Like aphids they inhabit young flush, secreting honeydew and causing leaf distortion. However, psyllid adults are stronger fliers than aphids and can survive longer without fresh flush. Asian citrus psylla was first reported in Florida in June, 1998. It can transmit “greening disease” caused by a phloem-limited bacteria. Greening is the most serious disease of citrus in Asia but has not yet been reported in the U.S.
