History of Introduction and SpreadTop of page
Risk of IntroductionTop of page
Hosts/Species AffectedTop of page
X. perforans is widely distributed and very common. It attacks hundreds of host plant species in many plant families in forests and plantations(Browne, 1961; Schedl, 1963; Gray and Wylie, 1974), and has been intercepted in Japan and elsewhere from imported timber of many species and families (e.g. Ohno et al., 1987, 1988, 1989; Ohno, 1990). Its wide host range, coupled with its tolerance of a considerable range of climatic conditions, makes it a potential pest in forest plantations. It is normally found in dying, dead and newly-felled trees, and usually infests material of a moderate to large size. Given the great range of host trees attacked, and the differences between geographical areas, it is not possible to distinguish 'main host' trees from 'other host' trees. It may be expected that almost any crop, plantation or ornamental tree in a particular area can be attacked. The list that is given here is a small selection of hosts only.

Means of Movement and DispersalTop of page
Both adults and larvae of X. perforans are dependent on the growth of the fungus on the walls of the gallery system in the wood for their food. The fungus is transmitted by the female in a mycangium. In X. perforans, this most probably consists of mandibular pouches, as in related species, including X. volvulus (Francke-Grosmann, 1966; Beaver, 1989). 'Contamination ' of the mycangia by the spores of pathogenic fungi is possible. Spores of pathogenic fungi can also be transported on the cuticle of the beetle, although their chance of survival there is much less than in the mycangial pouch. No specific studies have been made on fungi associated with X. perforans.

Prevention and ControlTop of page
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. Pesticides should always be used in a lawful manner, consistent with the product's label.
When Xyleborus species are detected in plant material in areas outside the present range of the species, it is necessary to immediately destroy all of the infested material. When they are detected in traps, plant material in the vicinity of the trap should be actively inspected, with special attention directed towards imported woody products such as crating, dunnage and lumber milling scraps. If an active infestation is detected, control using insecticides is possible but is of limited effectiveness. Chemical control is not generally effective because the adult beetles bore deep into the host material. However, Jose and Thankamony (2005) found that a mixture of carbaryl and quinalphos was highly effective (99%) against infestation of rubber trees by Xyleborus perforans and X. similis, when swabbed weekly on the beetle-infested region of the bark. Jagginavar and Naik (2005) also report on the management of X. perforans in pomegranate orchards using insecticide mixtures. The following insecticides were used against the ambrosia beetle, Euwallacea fornicatus, which is destructive to tea: fenvalerate, deltamethrin, quinalphos and cypermethrin (Muraleedhaan, 1995). Selvasundaram et al. (2001) found that lambda-cyhalothrin 2.5 EC was more effective in reducing E. fornicatus populations than fenvalerate. Jose et al. (1989) suggest the use of solutions of boric acid and borax, which have both fungicidal and some insecticidal action, to protect stored wood. These insecticides may also be effective against other ambrosia beetles, but the concealed habitats in which these species feed and reproduce, the difficulties and high costs of insecticide application, and environmental concerns all limit the effectiveness of chemical control. The use of the parasitoid, Phymastichus xylebori, which attacks the adult beetle, has been suggested by LaSalle (1995). However, it seems unlikely that this would be practical or effective. In logging areas, prompt removal of the felled timber from the area will reduce attacks, and rapid conversion to seasoned, sawn timber will reduce the depth of such attacks as have occurred (Roberts, 1987). It should be noted that debarking may increase the susceptibility to attack (Supriana et al., 1978). X. perforans normally forms part of a complex of bark and ambrosia beetle species attacking felled trees, and control measures need to be directed against all species at the same time (Beaver, 2000).
