Common names: Eucalyptus longhorned borer, Australian Eucalyptus Longhorn beetle, Phoracantha semipunctata is an invasive, longhorn, beetle pest species of many species of Eucalyptus, especially E. globulus and E. viminalis It probably was introduced to New Zealand from Australia in the 1870s in railway sleepers. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control.

Many residents of California find the growth form, evergreen foliage, floral show, and other horticultural qualities such as drought tolerance highly desirable attributes of eucalyptus trees. This involved felling 40 trees each of jarrah (Eucalyptus marginata) and marri (Corymbia Consequently, insect pests and diseases associated with growing plants were not introduced with living trees.

The Eucalyptus longhorned borer Phoracantha semipunctataFabricius is an endemic Cerambycid beetle to the Northern Jarrah Forest (NJF) of south-western Australia that attacks stressed trees. EPPO, 2020. NATURAL HISTORY AND BEHAVIOR OF P. semipunctata Phoracantha semipunctata, a native of Australia, was first detected in southern California in 1984, where it continues to be a serious pest of Eucalyptus (Scriven et al., 1986; Paine et al., 1995). Brazilian Journal of Biology, 62(4B), 853-860. doi: 10.1590/S1519-69842002000500015, Orousset J, 1984. These beetles may also wander into houses by mistake as "accidental invaders." CABI/EPPO, 2007.

DOI:10.1017/S0007485300041225. Although described from specimens collected in Italy, the encyrtid egg parasitoid Avetianella longoi, is native to Australia and has been widely distributed around the world. It is a vital part of the enviromemt in Australia however in California, USA, it has been classified as an invasive pest species of eucalyptus originating from Australia.

It currently occurs throughout Califor- nia wherever eucalyptus trees grow. When these trees experience prolonged dry periods, they undergo drought stress and this makes them susceptible to attack by these beetles. El-Yousfi M, 1982. Journal of Economic Entomology, 96:370-376. Entomologist's Monthly Magazine. This parasitoid is unable to kill eggs of P. recurva as effectively as it has killed eggs of P. semipunctata even though these two beetles are very closely related. Patterns of host utilization by two parasitoids (Hymenoptera : Braconidae) of the eucalyptus longhorned borer (Coleoptera : Cerambycidae). The cambial layer contains the phloem (food conducting tissues; old phloem becomes bark) and xylem (water conducting tissues; old xylem becomes wood). : Platygasteridae) egg parasitoid of Phoracantha semipunctata (Col.: Cerambycidae), in Morocco.

Annals of the Entomological Society of America, 88:666-671. Biology and host relations of Avetianella longoi. A parasitoid egg is then laid next to the paralyzed host and upon hatching the parasitoid larva feeds on the eucalyptus longhorn borer beetle larva eventually killing it. The two species are easily separated by the patterns on the wing covers (elytra) that lie across the backs of the beetles. 79. Moore KM, 1963. Exarate (i.e. PQR database. The eucalyptus longhorned borer (Phoracantha spp.) However, exfoliating bark and dropped leaves can rapidly create flammable fuel loads under trees or on house roofs, sudden limb drop can damage property and injure people, and invasive growth habits of some species are problems associated with these common urban forest trees in California. College of Natural and Agricultural Sciences. Biological control in IPM systems in Africa. In: EPPO Global database, Paris, France: EPPO. The Problem: Phorocantha beetles are attracted to freshly cut eucalyptus wood, dying limbs, and trees suffering from stress, especially lack of water. The parasitoids pupate inside the host tunnels and upon completion of development they emerge from host trees to commence mating and host searching. Mating behavior of the Eucalyptus longhorned borer (Coleoptera: Cerambycidae) and the adaptive significance of long 'horns'. Phoracantha semipunctata [on eucalypts] in southwestern Spain. are native to Australia and New Guinea. © 2020 Regents of the University of California. Also, viable eggs can be laid on sprayed areas before the pesticide can kill the female beetles. This insecticide is injected directly into the tree’s vascular system and is released quickly to help kill insects already inside the vascular system. Resumen de la campaña de colocación de arboles cebo.). Suitability of the eggs of two species of eucalyptus longhorned borers (Phoracantha recurva and P. semipunctata) as hosts for the encyrtid parasitoid Avetianella longoi. One of these, Syngaster lepidus has been become established and parasitizes around 27% of Phorocantha larvae. The body is shiny dark reddish-brown, and a yellowish band extends across the upper half of the elytra (the hardened forewings) with one yellow spot and a prominent spine at the end. Female parasitoids lay eggs inside the eggs of P. semipunctata and parasitoid larvae consume the contents of beetle eggs killing them. It would appear that another parasitoid species from Australia that is specific to the eggs of P. recurva is needed to provide effective biological control of this pest.

Entomophaga, 33(3):381-382, Gonzalez Tirado L, 1986. Nouvelle Revue d'Entomologie, 1(3):322. The antennae of the females are approximately the same length as the body; those of the males are somewhat longer and heavier, with spines on segments 3-8. Living Eucalyptus trees are not easily protected by pesticides, as the beetles' behaviour limits their exposure to the chemicals; the beetles hide during the day under loose bark and do not feed on leaves or bark. There is a yellowish brown area in middle of the elytra, and a yellowish brown patch near the tip. The ICRs are applicable to Timber with and without bark. Bybee LF, 2003. In: Neuenschwander P, Borgemeister C, Langewald J, eds. Elongate-oval, spindle-shaped, yellowish, 2.5-3.0 mm long, laid in groups of 30-40 in a single layer. Eucalyptus saligna, E. globulus, E. nitens, E. viminalis, and E. diversicolor are highly susceptible to Eucalyptus longhorned borer in Freshly cut trap logs, treated with pesticide, are placed in woodlots to attract adult beetles.

Eucalyptus Longhorned Borers Recommended Steps to Control Eucalyptus Long-horned Borers If caught early enough, immediately apply Multi-Insect Killer Tree Injection Kit to the tree. They are characterized by prominent long antennae, an obvious feature that is characteristic of cerambycid or long horn beetles. Two closely related species of longhorned borers (family Ceramby- cidae) attack eucalyptus in California. 156 (1), 51-57.
