PEST NOTES Publication 7425 University of California Statewide Integrated Pest Management Program Agriculture and Natural Resources September 2009 Two closely related species of longhorned borer beetles (family Cerambycidae) attack eucalyptus trees in California. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. Luhring KA, Paine TD, Millar JG, Hanks LM, 2000. The effect of host size on the sex ratio of Syngaster lepidus, a parasitoid of Eucalyptus longhorned borers (Phoracantha spp.). 1) was introduced into southern California in the 1980s and rapidly became a pest. The Situation: Approximately 90 of the more than 700 species in the tree genus Eucalyptus have been introduced into North America over the last 150 years. Appearance of Phoracantha semipunctata.

This insecticide is injected directly into the tree’s vascular system and is released quickly to help kill insects already inside the vascular system. Phoracantha semipunctata (eucalyptus longhorned borer); larvae and larval galleries in Eucalyptus grandis. Cadahia D, 1980. Extensive damage to the cambial layer "ring barks" or girdles trees and the destruction of phloem and xylem means infested trees can no longer move water and nutrients from the roots to the leaves. Comparison of the abundance, life cycle and oviposition preference between Phoracantha semipunctata F. and P. recurva Newman, two xylophagous pests in Moroccan eucalypts. DOI:10.1017/S0007485300041225. The parasitoid can complete around six generations for every beetle generation, and by preventing the hatching of eggs, damage to eucalyptus trees by boring beetle larvae has been greatly reduced. Way M J, Cammell M E, Paiva M R, 1992. It provides excellent biological control of P. semipunctata in some areas (Hanks et al., 1995a; Paine and Millar, 2002), but may contribute to the replacement of P. semipunctata by P. recurva in areas where both species have been introduced (Luhring et al., 2000). When several references are cited, they may give conflicting information on the status. The major damage these beetles cause to eucalyptus is done by feeding beetle larvae.

Interestingly, the very effective control of P. semipunctata by A. longoi has reduced competition with P. recurva and this lack of competition and ineffective attacks on eggs has allowed P. recurva to emerge as a more serious pest of eucalyptus than it previously was. Joyce AL, Millar JG, Paine TD, Hanks LM, 2002. Photo about Eucalyptus long-horned beetle isolated on the white background. The eucalyptus longhorned borer (ELB) was first identified in California in 1984 and has since killed thousands of eucalyptus trees. Europe - insect pests on eucalyptus. Evaluation of cold temperatures and density as mortality factors of the eucalyptus longhorned borer (Coleoptera: Cerambycidae) in California. The longhorn beetles (Cerambycidae; also known as long-horned or longicorns) are a large family of beetles, with over 26,000 species described, slightly more than half from the Eastern Hemisphere. Mechanisms of resistance in Eucalyptus against larvae of the eucalyptus longhorned borer (Coleoptera: Cerambycidae). Once the cambial layer of the tree is reached the majority of the feeding occurs here. 82 (3), 425-432. Anon., 1981. Trees with this type of extensive feeding damage often die. CABI/EPPO, 2007. The two species are easily separated by the patterns on the wing covers (elytra) that lie across the backs of the beetles. [Distribution map]. It currently occurs throughout Califor- nia wherever eucalyptus trees grow. CABI Compendium: Status as determined by CABI editor. The parasitoid Platystasius transversus was obtained from eggs of P. semipunctata in Morocco (Fraval and Haddan, 1988). Consequently, insect pests and diseases associated with growing plants were not introduced with living trees.

Wallingford, UK: CABI, Map 272 (2nd Revision). 376:55, Fraval A, Haddan M, 1988. Drought stress is exacerbated in many areas of California because many eucalyptus trees are growing in unmanaged or minimally managed environments with no supplemental irrigation. 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. Direction des Eaux et des Forêts, Rabat, Morocco. en el Suroeste español. Museum set specimen. The ovipositor is moved around in the tunnel until the beetle larvae is detected. The parasitoids pupate inside the host tunnels and upon completion of development they emerge from host trees to commence mating and host searching. Annales de l'Institut National de Recherches Forestières de Tunisie, 2:1-37. More information about modern web browsers can be found at http://browsehappy.com/. Hanks LM, Paine TD, Millar JG, Campbell CD, Schuch UK, 1999. In its native country, Australia, P. semipunctata occurs throughout Eucalyptus forests, but its damage is usually restricted to dead and dying trees. Host species preference and larval performance in the wood-boring beetle Phoracantha semipunctata F. Oecologia, 95(1):22-29. While you have misidentified this Longhorn Borer Beetle, you did get the family correct. Phoracantha semipunctata, the Australian Eucalyptus longhorn, is a species of beetle in the family Cerambycidae, its common name is the eucalyptus longhorned borer.

Phoracantha semipunctata in south-western Spain: control and damage. : Platygasteridae) egg parasitoid of Phoracantha semipunctata (Col.: Cerambycidae), in Morocco. Eucalyptus L'Héritier (Myrtaceae: Leptospermoideae) species are native to the Austro‐Malaysian region, but have been widely planted in temperate and subtropical regions around the world. Hanks LM, Millar JG, Paine TD, Wang Qiao, Paine EO, 2001. Perforator of eucalyptus in the south-east of Spain. CABI/EPPO, 1998. Selection of the appropriate tree species for each zone is the main preventive measure (Gonzalez Tirado, 1986; El-Yousfi, 1989). Consequently, insect pests and diseases associated with growing plants were not introduced with living trees. There are also some species less likely to be attacked by the Eucalyptus Longhorned Borer. The cambial layer is the only "living" part of the tree. Female beetles lay their eggs on the sprayed logs which are replaced every 2 weeks with fresh ones. Two prominent borer pests in the Brisbane area are the eucalyptus longhorned borer (Phoracantha semipunctata) and the Poinciana borer (Agrianome spinicollis). Eucalyptus trees are attacked by several other types of insects, including eucalyptus longhorned borers, several psyllids, and more innocuous species such as the lemongum gall wasp (Epichrysocharis burwellii).

As the tree grows it constantly renews phloem and xylem tissues, and only the new xylem and phloem transport water and nutrients. Biological Control, 19(2):95-104; 36 … P. semipunctata has become established in virtually all regions of the world in which eucalypts have been planted. The longhorn Phoracantha semipunctata: to be feared in eucalyptus plantations. 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). Martinez Egea JM, 1982. The population dynamics, distribution and biology of P. semipunctata in its native habitat are poorly understood. Entomologia Experimentalis et Applicata, 74(2):185-194. The elytra (wingcases) are yellow-brown, with 2 vaguely connected spots per wing and a thick black band crossing both at the posterior end. In its native Australia, eucalyptus longhorned borer is a minor pest that primarily attacks dead eucalyptus trees and downed limbs. Body size influences mating success of the Eucalyptus longhorned borer (Coleoptera: Cerambycidae). 27 (6), 1418-1424. Paine TD, Hanks LM, Millar JG, Paine EO, 2000. Wallingford, UK: CAB International. Biological control of defoliating and phloem- or wood-feeding insects in commercial forestry in Southern Africa. It has been estimated that up to 90% of P. semipunctata eggs that are laid under bark on eucalyptus trees are killed by A. longoi. Distribution Maps of Plant Pests, No.June. Recommended preventive measures are concerned with managing the forest in such a way that trees are kept in good health. Exp. In 1995, approximately ten years after the introduction of P. semipunctata, a second cerambycid species, Phoracantha recurva, was found in southern California (Los Angeles, Riverside, and San Bernardino Counties) attacking eucalyptus. This encyrtid egg parasitoid from Australia, was imported into California in 1992, and was established in this state by 1993. In a number of countries where euca- lyptus has been introduced, however, the beetle has even- tually followed and become a devastating pest that attacks apparently healthy trees. The destructive Phoracantha beetle and its control. Bulletin of Entomological Research, 92(2):147-151; 38 ref. Boleti^acute~n de la Estacio^acute~n Central de Ecologi^acute~a, 11(22):57-69; [5 col. Research: University of California scientists have conducted a very successful biological control program against P. semipunctatawith parasitic wasps that are very specific to this pest beetle.
