I have a mature Navel Orange tree, and a mature Tangelo tree. The Tangelo tree has what looks like the Asian Citrus psyllid on the new green growth leaves. I would like to have someone from the UC Agricultural Extension have a look at my tree. The mature Navel Orange tree has brown spotted old leaf's..  
These are my beautiful old trees that I do not want to loose or to have it spred to other Citrus growers in my neighborhood. My next door neighbor lost both her Mature Navel Orange and her lemon tree last year. We did not have knowledge of this pest until I heard broadcasted on my radio today.

Hi Raciel, If you live in California and think you have Asian citrus psyllid on your tangelo tree, please call the California Food and Agriculture (CDFA) Exotic Pest Hotline at (800) 491-1899. Pictures of the Asian citrus psyllids and its life stages are on the UC ANR website at
