I did numerous searches in the Google database to find a list of hosts
for Psiloptera spp., and have brought together my findings below.
You'll note that the three lists don't overlap all that much, which is
somewhat of a mystery to me. I have determined that this beetle is a
problem on tamarisk and eucalyptus trees, and thus is of concern
during importation of those (see the report cited in the third list).
Host plants of West-Palearctic Buprestidae
ACACIA: Psiloptera catenulata, Psiloptera arabica?
POINCIANA: Psiloptera catenulata
PUNICA: Psiloptera catenulata
TAMARIX: Psiloptera catenulata
ZYGOPHYLLUM: Psiloptera mimosae
Woody Ornamental Plants And Their Insect Pests
Psiloptera drummondi: Acacia berlandieri, Prosopis glandulosa, Carya
illinoensis, Ulmus parvifolia
Risk Assessment of Importation into the United States of Unprocessed
Eucalyptus Logs and Chips from South America (page 31)
P. hirtomaculata: Eucalyptus tereticomis, E. tessellaris, E. torreliana
P. pardalis: Eucalyptus spp., Pinus tropicalis, Casuarina spp., citrus trees
To find these lists, I used the following keywords in the Google database:
pest OR pests
host OR hosts
plant OR plants
Then I condensed down the lists that were given me to get just the
information on Psiloptera spp., including searching within reports and
databases of species information.
Please let me know if I can help further on this or any other question!
