Draft IRA Report: table grapes from Chile Pest Common name Neoterius mystax (Blanchard) [Coleoptera: Bostrichidae] Otiorhynchus sulcatus (Fabricius) [Coleoptera: Curculionidae] Pantomorus ruizi (Brèthes) [Coleoptera: Curculionidae] Platyapistes glaucus Farhaeus [Coleoptera: Curculionidae] Platyapistes venustus (Erichson) [Coleoptera: Curculionidae] Diptera (flies) Ceratitis capitata (Wiedemann) [Diptera: Tephritidae] Associated with table grape cluster (yes/no) Comment Reference Consider pest further? (yes/no) Fence borer No An opportunistic borer pest of vines. Found in Vine weevil; black vine weevil Alfalfa root weevil trunks and branches. Yes Larvae feed on small roots in the soil. Adults feed on foliage, as well as any portion of the inflorescence. O. sulcatus can cause damage to grapes by feeding on the pedicels and cluster stems. No Adult feeds on foliage, larvae are of a subterranean habit. Gonzalez, 1983 No CABI, 2002; Phillips, 1981 Yes (WA only) SAG, 2002 No Weevil No Associated with leaves and buds. Gonzalez, 1983 No Green weevil No Associated with leaves and buds. Gonzalez, 1983 No Mediterranean fruit fly Hemiptera (aphids, leafhoppers, mealybugs, scales, true bugs) Yes Chile is considered a pest free area for this pest but it could be associated with the pathway if it became established. Highly polyphagous. Causes damage to a wide range of unrelated fruit, primarily through oviposition into the fruit where larvae feed internally. Hancock et al., 2000 Yes Page 22
Draft IRA Report: table grapes from Chile Pest Common name Aphis fabae Scopoli [Hemiptera: Aphididae] Aphis illinoisensis Shimer [Hemiptera: Aphididae] Balclutha aridula (Linnaeus) [Hemiptera: Cicadellidae] Icerya palmeri Riley-How [Hemiptera: Margarodidae] Associated with table grape cluster (yes/no) Comment Reference Consider pest further? (yes/no) Black bean aphid Yes Young colonies consist of matt black aphids on young shoots, older colonies spread over most of aerial parts of the plant. Grapevine aphid Yes Damages young shoots, leaves. When Ballica leafhopper Margarodes scale populations are high, some may feed on fruit clusters, causing some berries to drop. No Little is known about this species. Other species of leafhopper found on grapes feed on leaves. Heavily damaged leaves lose their green colour, dry up and may fall off the vine. Leafhopper production of honeydew can result in spotting of fruit. Overwinter as adults, and are found on newly emerged grape leaves. Adults and nymphs feed on leaves by puncturing leaf cells and sucking out nutrients. Unknown Little information is available on this species. In general, Margarodidae live on a wide variety of hosts, especially woody plants. Damage to the plant is caused by sap depletion, introduction of toxins and the production of honeydew hindering photosynthesis. Blackman & Eastop, 1984 Pfeiffer & Schultz, 1986 Yes Yes USDA, 2002 No Morales, 1991 Yes Leptoglossus chilensis (Spin.) Brown Chilean No Little information is available on the biology of this Fasulo & Stansly, No Page 23
