Notes on Taxonomy and NomenclatureTop of page
This insect was first described in 1758 by Linnaeus as Cerambyx sutor and was later placed in the genus Monochamus.
DescriptionTop of page
Detailed descriptions of the life stages of M. sutor are provided by Cherepanov (1990).
The eggs are white, matte, becoming brownish with time, elongate, slightly curved, rounded at poles, overall length 3.8 mm, width 0.8 mm.
The larvae are white, opaque legless grubs, averaging 35-40 mm in length when mature. The head capsule is amber in colour, with well developed, black chewing mouthparts. Overall, the body length of mature larvae is 40-50 mm; the width of the head is 4.1-4.7 mm.
The pupae are moderately elongate, white, opaque and cylindrical. They are exarate, with antennae, legs and wings free from the body. The abdomen is elongate, gradually tapering to a posterior tip.
The overall body length of the adult is 15-26 mm. The body is moderately elongate with head not broader than the pronotum. Head and pronotum have a deep median longitudinal groove with deep uneven punctuation and dense or sparse grey or brownish hairs. The antennae are 2.5 times the length of the body on males and less than 1.5 times the length of the body for females. The eyes are deeply faceted, broadly emarginated, with the upper ocular lobes close to each other. The distance between the ocular lobes is less than the interspace between the antennal bases. The scutellum is whitish-yellow and the prothorax has a pair of projections. The elytra have several irregular, faint, bronze or gold coloured markings. Females are slightly larger than males.
DistributionTop of page
M. sutor is found throughout the conifer forests of Eurasia from the Atlantic Coast east to the Pacific (Cherepanov, 1990).
Official surveys have been carried out regularly in Denmark since 2000. None of the pre-surveillance records reported in Bílý and Mehl (1989) or Althoff and Danilevsky (1997), or later transient interceptions have led to the establishment of Monochamus species. It is therefore concluded that Monochamus species are not known to occur in Denmark (Danish Plant Directorate, 2010).

Risk of IntroductionTop of page
Adult Monochamus beetles are strong fliers. However, the normal flying distance for Monochamus adults in forests is fairly short. In the case of Monochamus alternatus, an important vector of pinewood nematode in China and Japan, most adults fly less than 200 m, although some individuals have been known to fly up to 3.3 km (Kobayashi et al., 1984; USDA APHIS, 1999).
All life stages of M. sutor can be transported over long distances via international trade in unprocessed logs. The larvae and pupae can survive in lumber cut from infested logs and can develop into adults. Lumber, wooden crating, pallets and dunnage used in international trade are therefore potential sources of introduction of M. sutor and other species of Monochamus. According to data available from APHIS, insects identified as Monochamus spp. were intercepted over 250 times at ports of entry in the USA between 1985 and 1998. A single adult M. sutor was intercepted from wooden crating arriving at the airport in Curitiba, Brazil, from Italy (ET Iede, EMBRAPA, Parana, Brazil, personal communication, 2001). In 1998, more than 100,000 m³ of larch was imported from Russia to Austria. This material contained several species of longhorned beetles including M. sutor (Krehan and Holzschuh, 1999).
M. sutor is a known vector of a Eurasian pinewood nematode, Bursaphelenchus mucronatus (Tomminen et al., 1989; Schroeder and Magnusson, 1992). Infection occurs during adult maturation feeding and oviposition when the nematode larvae emerge from the spiracles of beetles, drop onto the twigs and penetrate the woody tissue through the feeding wounds (Speight and Wainhouse, 1989). Damage caused by this nematode in the forests of Europe and Asia is minimal and similar to that caused by the pinewood nematode (Bursaphelenchus xylophilus) in North America. However, when B. xylophilus was introduced into Asia, it became a devastating pathogen (Kulinich and Orlinski, 1998). B. mucronatus must therefore be regarded as having the potential to become a devastating pathogen of North American conifers. Three other nematodes, Parasitorhabditis welchi, Bursaphelenchus sutoricus and Cryptaphelenchus sutoricus, are reported to be associated with M. sutor in the Republic of Georgia (Devdariani, 1974).
HabitatTop of page
Within its native distribution, M. sutor generally confines its attacks to stressed or recently killed trees and freshly cut logs or windthrow. In Siberia, mass breeding occurs in forests damaged by wildfire or defoliated by the Siberian silkworm, Dendrolimus sibiricus, and in recently felled trees (Cherepanov, 1990).

Hosts/Species AffectedTop of page
M. sutor attacks species of fir (Abies), spruce (Picea), pine (Pinus) and larch (Larix) across its geographic range. In Europe, Abies alba, Picea abies and Pinus sylvestris are attacked (Hellrigl, 1971; Bakke and Kvamme, 1992; Schroeder et al., 1999). In China, reported hosts are Larix gmelinii, Pinus sylvestris var. mongolica and Betula platyphylla (Zhang et al.,1993; Li et al., 1988). In Siberia and the Russian Far East, M. sutor is reported from Abies holophylla, A. nephrolepis, A. sibirica, Larix gmelinii, L. sibirica, Picea koraiensis, P. jezoensis, P. obovata, Pinus sylvestris and P. sibirica (USDA Forest Service, 1991).

Growth StagesTop of page
SymptomsTop of page
Symptoms associated with infestations of M. sutor are not specific and are more or less typical of all species of Monochamus.
Infested trees contain narrow slits in the bark indicative of oviposition sites, boring tunnels in the cambium and wood filled with frass, which superficially resemble straw or coarse wood shavings, and adult exit holes that are round to slightly oval in shape.
Adult maturation feeding consists of the removal of bark from the shoots of host trees. The shoots eventually die leaving dead tips with reddish-brown foliage on the trees. The shoots may eventually break, giving the trees a pruned appearance.

Biology and EcologyTop of page
Life History and Habits
The genus Monochamus is comprised of 150 known species distributed across Asia, Africa, Europe and North America (USDA APHIS, 1999). Twenty-four species of Monochamus have been recorded from China and about 10 species are native to North America (Furniss and Carolin, 1977; Drooz, 1985; USDA APHIS, 1999). All species indigenous to the temperate regions attack various species of Pinaceae and confine their attacks to trees that are stressed or recently killed by bark beetles, lightning, disease or climatic and site-related factors. Some species can be damaging to windthrow or recently felled pulpwood or sawlogs. Several African species of Monochamus are pests of tropical broadleaf trees and some (e.g. M. scabiosus) have a tendency to attack healthy trees (Browne, 1968).
In Siberia, M. sutor has a 2-year life cycle. Adult flight occurs between June and mid-September. After the adults emerge from host trees, they feed on the bark and phloem of twigs in the crowns of conifers. The damaged shoots often break off, giving the trees a pruned appearance. Adults are attracted to weakened, dying or recently dead trees or logs to mate and lay eggs (Cherepanov, 1990).
Females deposit about 50 eggs, in groups of 1-6 eggs, in niches cut into the bark of host trees (USDA Forest Service, 1991). In northern China, trees are suitable for attack from the trunk base to within 3.3-4.6 m from the top for trees 13-23 m in height (Zhang et al., 1993). During the first year, the larvae feed under the bark. They later bore into the wood, constructing oval galleries, where they overwinter as second-instar larvae. During the second year, the larvae continue to feed and bore deeper into the wood. The larvae have five instars. Mature larvae form pupal cells near the bark surface, where they spend the second winter as pupae. Adult emergence occurs in the following spring (USDA Forest Service, 1991).

Economic ImpactTop of page
M. sutor is a member of an important wood-boring group of Cerambycidae. These insects damage the wood of weakened, recently dead and downed conifers, causing degradation and loss of structural integrity of lumber. In some areas they often attack conifers killed by bark beetles, fire or weakened by defoliating insects. Moreover, if logs are stored in the forest or at the sawmill for prolonged periods before processing, they are subject to attack by species of Monochamus.
This longhorned beetle is a commonly occurring insect across much of its natural range. Attack densities can be extremely heavy in down material, with up to 100 eggs deposited per metre of log surface (Bistimmungensüben an Insekten, 2002). In northern China, M. sutor is one of the most prevalent stem-infesting insects in burned over areas (Zhang et al., 1993). In the Baikal region of Asian Russia, M. sutor is an important pest of harvested logs. In one study, between 10 and 80% of the larch in a timber yard was found to be infested by M. sutor. Another report indicates that this insect destroyed a large volume of timber during the construction of the Bratsk Reservior (USDA Forest Service, 1991).
Environmental ImpactTop of page
In its native habitat, and in the absence of a pathogenic species of pinewood nematode, the environmental impact of M. sutor, by itself, is probably beneficial. It is part of a complex of insects that play a role in the decomposition of dead conifer wood.
Detection and InspectionTop of page
Look for larval galleries, granular frass and various life stages of the insect in unprocessed logs, lumber, wooden crating, pallets and dunnage. The presence of round or slightly oval exit holes in logs or wood in use is an indication that adults of the genus Monochamus may have emerged from this material.
Similarities to Other Species/ConditionsTop of page
Adults tend to be similar in appearance to other palaearctic species of Monochamus. Examination of adults by a taxonomist with expertise in the family Cerambycidae is necessary for sound species identification, especially if specimens are found outside of its known geographic range.
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.
Recommended cultural measures for the management of various species of Monochamus emphasize the prevention of attacks. These measures include avoiding storage of recently felled sawtimber and pulpwood in forested areas during the adult flight period, which is usually from May to September; prompt salvage and utilization of windthrow and/or trees killed by bark beetles, lightning or disease and storage of logs under a water spray at sawmill sites (Furniss and Carolin, 1977; Drooz, 1985).
No chemical control methods are available for M. sutor.
Heat treatment at 60 or 70°C for 1 hour kills all stages of Monochamus urussovii. This could be accomplished in a kiln or with steam or hot-water treatment (USDA APHIS, 1991). This treatment should be effective for all species of Monochamus and could be applied to wood products destined for export.
Some species of Monochamus are attracted to host volatiles and are known to come to traps baited with alpha pinene.
Some field monitoring of Monochamus species has been done using traps baited with host attractants. In China, traps baited with alpha pinene have been used to determine whether local populations of Monochamus alternatus are infected with pinewood nematode.
Integrated Pest Management
Integrated pest management of longhorned beetles of the genus Monochamus emphasizes the prevention of attacks (see Cultural Control). In Mexico, avoiding the planting of pine on poor growing sites is recommended to prevent attacks by Monochamus clamator rubigineus (Cibrián Tovar et al., 1995).
