ENTOMOLOGY SECTION
Compiled by Susan E. Halbert, Ph.D.

For the month of September, there were 278 samples consisting of 6,291+ specimens. In October, there were 292 samples consisting of 8,569+ specimens. Some of the samples processed are listed below:

ORNAMENTALS, PALMS AND WOODY PLANTS: Eucalyptus cinerea (silver-dollar eucalyptus)-- psyllids: Large numbers of psyllid eggs and 1st instar nymphs were found on cut eucalyptus foliage from California at a flower wholesale business in Orlando (Orange County; E99-2585; Terrence D. Williams; 22 September 1999). The eggs, which are tiny and might otherwise have been overlooked, were noticed because anthocorid predators (minute pirate bugs) also were found on the plants. California has several species of psyllids that are pests on eucalyptus, but so far, none occur in Florida. A biological control program has been implemented recently in California against the blue gum psyllid, Ctenarytaina eucalypti (Maskell). While this may be preferable to pesticides for California producers, incomplete control may increase the risk that eucalyptus psyllids could be introduced accidentally into Florida (Dr. Susan E. Halbert).

Murraya paniculata (orange-jessamine, orange-jasmine, Chinese box)-- Diaphorina citri Kuwayama, Asian citrus psyllid: Moderate infestations were found at a discount store in Lake Mary (Seminole County; E99-2360; Leslie J. Wilbur and Amanda D. Mattison; 27 August 1999) and at nurseries in Bradenton (Manatee County; E99-2676; Jennifer A. Lee; 29 September 1999) and Auburndale (Polk County; E99-2814; Stephen A.
