Abstract During a nationwide survey, 88 320 plants from eight
cut-flower species at 345 sites located in 13 districts in New Zealand were
examined for arthropods and molluscs from December 1994 to June 1995. One
hundred and eighty-six new arthropod and mollusc records were found on the
eight cut-flower species and 114 of these were considered to be potential
primary pests. Most new records were for calla (Zantedeschia spp.) (92)
and 50 of these were potential primary pests including 10 species of thrips.
Western flower thrips (Frankliniella occidentalis) was found in Auckland
on calla, rose (Rosa spp.), carnation (Dianthus caryophyllus L.),
and chrysanthemum (Chrysanthemum x morifolium). Twospotted spider
mite (Tetranychus urticae) was a significant potential pest of cymbidium
(Cymbidium spp.), carnation, gypsophila (Gypsophila spp.), and
rose. Onion thrips (Thrips tabaci) was a significant potential pest of
calla and New Zealand flower thrips (Thrips obscuratus) was a
significant potential pest on calla and rose. The oleander scale
(Aspidiotus nerii) was found at half the cymbidium sites
surveyed.
