This species is considered the most serious scolytid pest of pines in Europe. It is believed that four species of pines native to Florida might be susceptible to attack by Tomicus Liu, M.; Zhang, Z.; Liu, X.; Yao, J.; Du, T.; Ma, Y.; Shi, L. Discriminant Analysis of the Damage Degree Caused by Pine Shoot Beetle to Yunnan Pine Using UAV-Based Hyperspectral Images. In this study, a framework is proposed for identifying the severity of damage caused by, This is an open access article distributed under the, Note that from the first issue of 2016, MDPI journals use article numbers instead of page numbers. The adult pine shoot beetle eats growing shoots on pine trees, which can kill the shoot and branch. Damage may resemble that sometimes caused by Ips spp. During “maturation feeding,” young beetles tunnel into the center of pine shoots (usually of the current year's growth), causing stunted and distorted growth in host trees. Photograph by USDA. APHIS, in consultation with the National Plant Board, considers pine shoot beetle to be a minor pest that can be controlled locally, given its slow spread and the minimal damage it causes. Tomicus piniperda adults are brown to black, 3.5 to 4.8 mm long, and somewhat resemble individuals of Dendroctonus (southern pine beetle and black turpentine beetle) in general appearance, but the funicle of the antenna is composed of six antennomeres. Unmanned aerial vehicle (UAV)-based hyperspectral imaging is an effective technique for forest health surveying and monitoring. Photograph by Scott Bauer, USDA. Instead, the beetles harbor pinewood nematodes (tiny worms) that cause pine wilt. (pine tip moths), so shoot damage should be examined carefully (Thomas et al., 2006). An adult Tomicus piniperda (Linnaeus), a pine shoot beetle. Look for 2 to 3 mm circular exit and entrance holes created by the adults near the broken ends of the shoots. The larvae soon emerge and feed in separate galleries 2.5 to 10 cm Mountain pine beetle (MPB) is an insect native to the forests of western North America and is also known as the Black Hills beetle or the Rocky Mountain pine beetle. Because Tomicus piniperda occurs about as far south in the Old World as the latitude of Florida, it is considered a potential threat to at least some of the pine species intensively cultivated in Florida, as well as pine species in other states. Myelophilus piniperda) is in the same family as bark beetles and resemble bark beetles in appearance with their cylindrical shape. and any shoot damage should be carefully examined. Find support for a specific problem on the support section of our website. Pine shoot beetles are native to Europe and Asia where they cause Figure 7. Princeton, NJ: Princeton University Press.

Bulletin of Entomological Research 31: 247-251. Author to whom correspondence should be addressed. In this study, a framework is proposed for identifying the severity of damage caused by Tomicus spp. Tomicus piniperda can be distinguished from other members of the genus by the smooth second elytral interval on the declivity. Photograph by Gyorgy Csoka, Hungary Forest Research Institute, www.forestryimages.org. or by pine tip moths (Rhyacionia spp.) The new generation emerges through the bark and attacks new shoots on pine trees of all ages. Symptoms of attack include dieback, yellowing, and especially dead, bored-out shoots littering the ground under infested trees (USDA 1972). The pine shoot beetle. These individuals then move back into the trunks to construct new galleries and to lay a second batch of eggs. Pines (genus Pinus) are the main hosts for the beetle. PINE BARK BEETLE Pine Bark Beetles are small reddish to dark brown beetles about 1/4 to 1/2 of an inch long. Liu, Mengying; Zhang, Zhonghe; Liu, Xuelian; Yao, Jun; Du, Ting; Ma, Yunqiang; Shi, Lei. Figure 9. How could it get here? The females excavate galleries, 10 to 25 cm long, under the bark to lay their eggs with the galleries more numerous on the sides of logs and trees warmed by The statements, opinions and data contained in the journals are solely Economic Impacts. According to Hanson (1940), the worst damage caused by the beetle is the tip feeding: "This destruction of the growing points causes various forms of malformation ... and results in great reduction of the value of the crop." A bark beetle (. Pine shoot beetle can cause severe decline in the health of the trees in certain species of pine, Scots pine and Red pine in particular, and in some cases, kill trees when high populations exist, which reduces property values, and results in property owners having to pay for the removal of dead tree hazards. and The beetles damage the new growth by burrowing up to 10 cm into the pith. In May or June, larvae pupate at the end of their feeding galleries. In October, the adults move into the soil or the base of pine trees to overwinter. The adult beetles prefer to colonize freshly cut stumps and slash but can attack stressed living trees. Photograph by Bruce Smith, USDA AHPIS PPQ, www.forestryimages.org. A predatory beetle, Thanasimus formicarius Linnaeus, can eat several pine shoot beetles daily. Please let us know what you think of our products and services. Adult feeding damage caused by Tomicus piniperda (Linnaeus), a pine shoot beetle, showing browned flags from about 12 feet away. In addition, first and second year shoots droop and become yellow or red in early summer (Humphreys and Allen 1998). While adults can overwinter in shoots in warmer climates, they must move under the bark at the base of trees or the soil in colder weather. Biologically, this species of bark beetle is considered to be a secondary pest of pine and not able to successfully attack healthy trees. In Great Britain there is usually only one generation per year; in warmer countries there may be two generations annually. At any life stage, from egg to adult, the pine shoot beetle might be hiding in wood or wooden packaging material. the sun (Humphreys and Allen 1998). piniperda, based primarily on resin flow and bark characteristics: Forest resources that may be threatened include Christmas trees, pine landscape/nursery products, and pine timber. Studies by the Canadian Forest Service confirms that the pine shoot beetle completes one generation per year in that region and the northern United States. There apparently is no practical chemical control for this pest. Figure 8. Originating in Europe, North Africa and Asia, pine shoot beetles are a fearsome pest found in over 14 American states. and any shoot damage should be carefully examined. A quarantine on the movement of host trees from infested states exists, both from states that are not infested and between infested and non-infested of areas of states where the pine shoot beetle is established. However, it is a quarantine pest in nursery and Christmas tree production. or by pine tip moths (Rhyacionia spp.) They were detected in Ontario in 1993 and in Quebec in 1998.

European Pine Shoot Moth (EPSM) A shepherd's crook symptom or distorted tips of pine trees are indications of possible damage from European Pine Shoot Moth, Rhyacionia buoliana (Denis & Schiffermuller). 1972. Some pathogens also can cause dieback of new shoots such as Diplodia tip blight. Damage to pine shoots could be from pine shoot beetle, but a number of moths tunnel in pine shoots as caterpillars including Zimmerman pine moth and European pine shoot moth. White Pine Weevil Control Tips Attacks white pines, spruces More common in pure plantings Adults emerge in early spring when T > 50 F (as early as March in PA), Treat in early spring when adults emerge with borer pesticide Photograph by Steve Passoa, USDA AHPIS PPQ, www.forestryimages.org. Young adults are brownish black in colour and become darker over time. Damage to pine trees can affect many industries in Canada, including Christmas tree farms, saw log, and pulpwood industries. Loblolly pine is the most important commercial species with a growing volume in Florida of almost 675 million cubic feet. Most species are attacked, but only the non-native Scotch pine (Pinus sylvestris) seems to suffer badly. Figures were gathered from federal, state, and industry sources. The beetle prefers larger standing trees in which to lay eggs (at least 12 cm in diameter). Symptoms of attack include dieback, yellowing, and especially dead, bored-out shoots littering the ground under infested trees (USDA 1972). or by pine tip moths (Rhyacioniaspp.) Feeding by the Pine shoot beetle If you are in the Pine Shoot Beetle Compliance Program and need to apply a cover spray for pine shoot beetle, get ready, especially if you are in southern Lower Michigan. Chapter Eight: Stem and Twig Damagers- Common Pine Shoot Beetle. The damage may resemble what is sometimes caused by pine tip moths, so damage should be carefully examined. CONTROL: There apparently is no practical chemical conb"ol for this pest. Figure 1. Photograph by Gyorgy Csoka, Hungary Forest Research Institute, www.forestryimages.org. Infested shoots shrivel, begin to turn yellow, then red, and finally break near the entry hole dug by the beetle. or by pine tip moths (Rhyacioniaspp.) Tomicus piniperda (Linnaeus), a pine shoot beetle native to Europe, was first discovered in the United States in July 1992 in a Christmas tree plantation in Ohio. It attacks both the trunks and growing shoots of pines, especially Scotch pine, Pinus sylvestris L. In Europe, it occasionally attacks spruce (Abies sp.) Photograph by Robert A. Haack, USDA Forest Service, www.forestryimages.org. Figure 12. are important forestry pests that wreak havoc on pine trees and pose a threat to ecological stability.The pests are difficult to find because they can remain hidden in trees for long periods. Often they are waiting on the fallen pine trees and begin feeding on bark beetles as they land.

Pine Shoot Beetle, Tomicus piniperda (Linnaeus) (Insecta: Coleoptera: Curculionidae: Scolytinae) 3 After laying eggs in the galleries, the adults emerge and then die. Symptoms of attack include dieback, yellowing, and especially dead, bored-out shoots littering the ground under infested trees (USDA 1972). Due to the rapid removal of dead trees in the landscape, this beetle is not a common landscape pest. The beetle is found in numerous countries worldwide, including: Africa: Algeria, Canary Islands, China (northeast), Europe: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Finland, France, Germany, Great Britain, Greece, Hungary, Italy, Madeira, Netherlands, Norway, Poland, Portugal, Rumania, Russia, Slovakia, Spain, Sweden, Switzerland. "Discriminant Analysis of the Damage Degree Caused by Pine Shoot Beetle to Yunnan Pine Using UAV-Based Hyperspectral Images" Forests 11, no. Pine shoot beetle can cause damage in weak and dying trees, where reproduction and immature stages of pine shoot beetle occur, and in the new growth of healthy trees. The most significant damage occurs during the insect maturing period from July to October.

In addition, first and second year shoots droop and become yellow or red in early summer (Humphreys and Allen 1998). Thankfully, we have some environmental factors to boost our resistance, namely, the northern Great Plains itself. The common pine shoot beetle Tomicus piniperda (syn. Generally, pine beetles leave healthy trees alone. 12: 1258. After laying eggs in the galleries, the adult emerge and then die. Overwintering adults begin flights during March in the Great Lakes area, when daily maximum temperatures reach 10 to 12°C and the daily mean temperature is 7 to 8°C. Humphreys N, Allen E. (1998). • Shoots damaged by the pine shoot beetle will have 2-cm to 10-cm tunnels and may have circular entrance holes near the broken end (Fig. APHIS, in consultation with the National Plant Board, considers pine shoot beetle to be a minor pest that can be controlled locally, given its slow spread and the minimal damage it causes. Pine shoot beetle (PSB, Tomicus piniperda) is a pest of pines in Africa, Asia, and Europe. Trees may be destroyed by the tip feeding, or by the feeding in the trunk, or by attack of other insects caused by the stress. White line at bottom of image is 1 mm long. Pine beetles of all kinds – including the Western, Southern and mountain pine beetle – attack weak trees.

Work with your local arborist to create a long-term plant health care plan. Figure 2. Damage may look similar to damage caused by Ips spp. Close up of damage to pine tree by Tomicus piniperda (Linnaeus), a pine shoot beetle, showing infested tip. Still other insects, like the pine shoot beetle, may cause infested trees to be regulated by state or federal restrictions on shipping. This kind of damage would be especially severe in Christmas tree plantations, where tree form is the primary consideration, as "...the injuries caused by [Tomicus] are of a permanent character and the record of the insect's attack is indelibly stamped on the tree..." (Hanson 1937). Development from egg to adult requires about three months, with adults of the new generation beginning to emerge in June. The new adults are sexually immature and move into the tree crown to feed on the growing tips throughout the summer. A predatory beetle, Thanasimus formicarius Linnaeus, can eat several pine shoot beetles daily. Thomas, M.C. Photograph by Steve Passoa, USDA AHPIS PPQ, www.forestryimages.org.

Galleries created by Tomicus piniperda (Linnaeus), a pine shoot beetle. It especially attacks weakened, stressed, or dying trees, but will also attack and kill apparently healthy trees. The pine shoot beetle is present in Ontario, Quebec and New Brunswick. This species overwinters as an adult, either in hollowed twigs or in galleries at the base of the tree, emerging as early as February in warm localities to construct brood galleries at the base of the tree trunk. Though they prefer live trees Damage may resemble that sometimes caused by Ips spp. Snow pack adds insulation in many areas of Canada and the more northern United States (Humphreys and Allen 1998). The PSB and associated fungi can cause the quality of timber to deteriorate, resulting in negative implications for industries relying on high quality wood. Trees of all ages can be attacked, but dying, stressed (by drought, needle loss… The adults can fly for several kilometers to obtain a suitable host. It has recently been reported by Hui (1991) as a severe pest of Pinus yunnanensis L. in the Kunming Region of China, where it killed many apparently healthy trees and "...caused great economic losses.". This flow chart is intended to help Christmas tree growers, landscapers and MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. In Canada, it is established in the Great Lakes regions of Ontario and Quebec (Humphreys and Allen 1998, USDA 2010). Damage may resemble that sometimes caused by Ips spp. Cranshaw, W. (2004). If this beetle came into the country, it could bring other unwanted diseases with it, like pitch pine canker.
