Insect pest species of Eucalyptus in Gibraltar

Four invasive eucalypt-feeding insects, native to Australia, are recorded from Gibraltar for the first time: the gall-forming wasps Ophelimus maskelli (Ashmead) and Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae), the lerp-forming psyllid Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae), and the bronze bug Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae), whilst the status of two Eucalyptus longhorned borers, Phoracantha recurva Newman and P. semipunctata (Fabricius) (Coleoptera: Cerambycidae), is summarised. The former five species have been found on the red-gum tree Eucalyptus camaldulensis Dehnh., growing in the urban environment in Gibraltar. The potential impact of these invasive species is discussed.

Exotic bark- and wood-boring Coleoptera in the United States: recent establishments and interceptions

Summary data are given for the 25 new species of exotic bark- and wood-boring Coleoptera first reported in the continental United States between 1985 and 2005, including 2 Buprestidae (Agrilus planipennis and Agrilus prionurus), 5 Cerambycidae (Anoplophora glabripennis, Callidiellum rufipenne, Phoracantha recurva, Sybra alternans, and Tetrops praeusta), and 18 Scolytidae (Ambrosiodmus lewisi, Euwallacea fornicatus, Hylastes opacus, Hylurgops palliatus, Hylurgus ligniperda, Orthotomicus erosus, Phloeosinus armatus, Pityogenes bidentatus, Scolytus schevyrewi, Tomicus piniperda, Xyleborinus alni, Xyleborus atratus, Xyleborus glabratus, Xyleborus pelliculosus, Xyleborus pfeilii, Xyleborus seriatus, Xyleborus similis, and Xylosandrus mutilatus). In addition, summary interception data are presented for the wood-associated beetles in the families Bostrichidae, Buprestidae, Cerambycidae, Curculionidae, Lyctidae, Platypodidae, and Scolytidae, based on the USDA Animal and Plant Health Inspection Service "Port Information Network" database for plant pests intercepted at US ports of entry from 1985 to 2000. Wood-associated insects were most often intercepted on crating, followed by dunnage and pallets. The five imported products most often associated with these 8341 interceptions were tiles, machinery, marble, steel, and ironware. A significantly higher proportion of the most frequently intercepted true bark beetles have become established in the United States compared with the less frequently intercepted species.

The immature stages of Phoracantha recurva Newman, 1842 and Phoracantha semipunctata Fabricius, 1775 (Coleoptera, Cerambycidae) and a key to larvae of these species

The description of the last instar larva and pupa of Phoracantha recurva Newman, 1842 and the redescription of the immature stages of Phoracantha semipunctata Fabricius, 1775 showing new characters of possible diagnostic value are presented in this work. A key of identification of both species based on these characters is also given.

Insect pests of eucalypts in California: implications of managing invasive species

For the first 150 years following their introduction, eucalypts planted in the California landscape were free of both insect pests and diseases. In the last 15 years, numerous herbivorous insect species have been introduced accidentally into the State and have caused significant damage to the trees. Several of these species, e.g. Phoracantha semipunctata (Fabricius), Phoracantha recurva Newman (Coleoptera: Cerambycidae) and Gonipterus scutellatus Gyllenhal (Coleoptera: Curculionidae), have also been introduced into other parts of the world where eucalypts are grown, whereas others, e.g. Glycaspsis brimblecombei Moore (Hemiptera: Spondyliaspidae) and Eucalyptolyma maideni Froggatt (Hemiptera: Spondyliaspidae), are currently restricted to California and Australia. Research programmes have provided management solutions to individual pest problems, but as more pest species are introduced, these solutions must be integrated across broad geographic, horticultural, and economic scales, in a systems approach.
