and Bain, J. 215. For most of its history, the Asian longhorned beetle occupied a small, largely unremarkable niche in the forests of China, Korea and Japan. The exotic longhorn beetle Arhopalus tristisis a pest of pines, particularly those damaged by fire, and a major export quarantine issue in New Zealand. Fig. Journal of Chemical Ecology 27 :1091-1103. Monitoring of A. tristis (and other wood-boring and bark beetles) can be conducted using Lindgren funnel traps with lures of alpha-pinene and ethanol (Brockerhoff et al 2006). Bradbury, P.M. 1998: The effects of the burnt pine longhorn beetle and wood- staining fungi on fire damaged Pinus radiata in Canterbury. , and could be useful for monitoring, for example to determine the beginning and end of the flight period, or to estimate population levels. The beetles emerge in the ratio of about two females to three males about 50 days after the fully grown larvae cut the exit holes. Key trees in these habitats include Douglas-fir, ponderosa pine, lodgepole pine, spruce, fir, hemlock, tamarack or larch, white-cedar, and sometimes aspen. Black spruce (Picea mariana (Mill. Each female can lay up to about 1000 eggs. and jack pine (Pinus banksiana Lamb.) Concentrated egg–laying results in large numbers of larvae and rapid deterioration of logs What is … Arhopalus tristis, Burnt pine longhorn beetle. Europe and Northern Asia; Africa; South and South-East Asia; Australasian - Oceanian; Description. Under crowded conditions later larval stages may enter the sapwood but, in the absence of competition, the cambial region is preferred. Because Monochamus beetles are known vector insects of pine wood nematodes in Korea and burnt pine trees can be used as oviposition habitats for Monochamus beetles, we investigated changes in the spatial (among fire severity classes) and temporal (between years) … It is arguably more elusive with than the riparian brush rabbit. 2001: Arhopalus tristis (F.) (Coleoptera: Cerambycidae). Although they cause no damage, this is a major problem because export timber must be free of live insects, and so far A. tristis does not occur in North America, Japan, and anywhere in the Southern Hemisphere other than New Zealand.

Insect: Arhopalus tristis (F.) (Coleoptera: Cerambycidae) (=Arhopalus ferus (Mulsant)) Arhopalus tristis does not usually cause much damage in the forest because infestations are normally limited to dead trees and woody debris. This behaviour often leads to them becoming hitchhikers on imported cargo or vessels. During flights which occur only at dusk and through the early part of the night, adults may travel more than 3 km to attractive hosts, such as fire-damaged trees. Burnt pine longhorn beetle, also known as burnt pine longicorn, is a pest of plantation forestry, particularly pine (Pinus spp.). Bibliography Fig. Areas surrounding yards where export timber is stockpiled before shipment should be kept free of A. tristis sources such as reject logs, log dockings, slabs, and dead or dying pines, especially those affected by fire. Actinograph recordings of caged individuals showed that males and females were most active from dusk to midnight. The roles of parasites, predators, and entomophagous fungi in New Zealand have not been examined in detail. Whether this applies to males to the same degree is still unclear. The majority of individuals complete their life cycle in one year but in one study about a third took two years. He manomano ngā hua ka whānau mai, he manomano ngā torongū ka oreore mai, me te aha, ka tere tonu te pōpopo haere o ngā poro rākau. Distribution   During the period when beetles are active, the window of opportunity for recovery of logs without sapstain may be as short as six weeks after a fire. New Zealand Forestry 43 : 28-31. New Zealand Forest Service, Forest and Timber Insects in New Zealand No. There is evidence that female beetles are attracted by pine volatiles from wood and bark, particularly from burnt trees or sawn timber. Hosking (1978). Pūtoi Order Coleoptera Whānau Family Cerambycidae Show in English Te Reo Te Rahi. Log exports to the USA in particular were in jeopardy recently because of such biosecurity issues. does not usually cause much damage in the forest because infestations are normally limited to dead trees and woody debris. It is also present in an isolated population of pine that is surrounded by prairie in the Cypress Hills area of southwestern Saskatchewan, which was likely infested in the early 1980s. 6 - Close-up of rear of larva, showing the two blackish projections by which the species can be identified. Furthermore, sapstain fungi, which are vectored by the beetles, reduce the value of any salvaged wood (Fig. Such traps are highly attractive to A. tristis , and could be useful for monitoring, for example to determine the beginning and end of the flight period, or to estimate population levels. Larvae feed in the inner bark of dead pine trees and logs, especially those killed by fire. A few species are serious pests. There is evidence that female beetles are attracted by pine volatiles from wood and bark, particularly from burnt trees or sawn timber. 7).Where larvae are numerous, the outer 50 mm of sapwood may be severely damaged six months after attack. Habitat: This beetle is native to China, Japan, Korea, and the Isle of Hainan and an accidental immigrant in North America. Larvae hatch in about 10 days and bore towards the inner phloem and cambium. Nō Ūropi. Fig. 1977: Arhopalus ferus (Coleoptera: Cerambycidae); its biology in New Zealand.
