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). The beetle prefers larger standing trees in which to lay eggs (at least 12 cm in diameter). Galleries created by Tomicus piniperda (Linnaeus), a pine shoot beetle. A predatory beetle, Thanasimus formicarius Linnaeus, can eat several pine shoot beetles daily. Originating in Europe, North Africa and Asia, pine shoot beetles are a fearsome pest found in over 14 American states. those of the individual authors and contributors and not of the publisher and the editor(s). Monitoring: Look for damaged shoots on Scotch pine in mid- to late-summer, when adults are feeding on live trees. Close up of damage to pine tree by Tomicus piniperda (Linnaeus), a pine shoot beetle, showing infested tip. The adults are black or … Cultural practices used in Europe include precise timing of cutting operations and the debarking of cut timber. or by pine tip moths (Rhyacioniaspp.) Figure 9. MPB primarily develop in pines such as lodgepole, ponderosa, Scotch and limber pines, … The common pine shoot beetle Tomicus piniperda (syn. Though, if their population is high, they may attack healthy ones as well. • 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. The pine shoot beetle. Feeding by the An adult Tomicus piniperda (Linnaeus), a pine shoot beetle, also showing boring damage to pine shoot. Tomicus piniperda (common pine shoot beetle) is a bark beetle native throughout Europe, northwestern Africa, and northern Asia. Hanson S. 1940. They are closely monitored and some regions have been placed under quarantine, perhaps because in Europe, the pest causes severe damage to several pine species. The PSB and associated fungi can cause the quality of timber to deteriorate, resulting in negative implications for industries relying on high quality wood. This flow chart is intended to help Christmas tree growers, landscapers and Damage has been reported in areas where pine plantations exist. It is believed that four species of pines native to Florida might be susceptible to attack by Tomicus Tomicus piniperda can be distinguished from other members of the genus by the smooth second elytral interval on the declivity. Other conifers (for example spruce, larch, fir, Douglas-fir) have also been attacked, but the beetle does not prefer them and only attacks them when little else is leftFootnote 1, Footnote 2.

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. 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 Symptoms of attack include dieback, yellowing, and especially dead, bored-out shoots littering the ground under infested trees (USDA 1972). Thanasimus formicarius disperse just before the flight of their prey (Tomicus piniperda and Tomicus minor as well as other bark beetles) or during, or just after. Biologically, this species of bark beetle is considered to be a secondary pest of pine and not able to successfully attack healthy trees. Forests 2020, 11, 1258. 2020; 11(12):1258. 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. Though they prefer live trees The adults of this second brood usually emerge late in the summer. White line at bottom of image is 1 mm long. Figure 8. The best time to spray will be right around 450-500 growing degree days base 50 . Look for 2 to 3 mm circular exit and entrance holes created by the adults near the broken ends of the shoots. Cranshaw, W. (2004). Figure 2. MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Both Thanasimus formicarius and the bark beetles are attracted to monoterpenes from the damaged areas of the fallen trees. Photograph by Scott Bauer, USDA. Damage may resemble that sometimes caused by Ips spp. Because pine shoot beetles can feed on any pine, they have the potential to cause billions of dollars in damage if they reach Western forests. 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. Figure 10. Figure 11. Due to the rapid removal of dead trees in the landscape, this beetle is not a common landscape pest. 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." 2020. 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. or by pine tip moths (Rhyacioniaspp.) Adult feeding damage caused by Tomicus piniperda (Linnaeus), a pine shoot beetle, showing browned flags from about 12 feet away. 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. or by pine tip moths (Rhyacionia spp.) 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. The larvae soon emerge and feed in separate galleries 2.5 to 10 cm Author to whom correspondence should be addressed. Chapter Eight: Stem and Twig Damagers- Common Pine Shoot Beetle. They were detected in Ontario in 1993 and in Quebec in 1998. Still other insects, like the pine shoot beetle, may cause infested trees to be regulated by state or federal restrictions on shipping.

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. 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. Some pathogens also can cause dieback of new shoots such as Diplodia tip blight. USDA. Unmanned aerial vehicle (UAV)-based hyperspectral imaging is an effective technique for forest health surveying and monitoring. Myelophilus piniperda) is in the same family as bark beetles and resemble bark beetles in appearance with their cylindrical shape. or by pine tip moths (Rhyacionia spp.) Damage to the shoots is usually limited to the upper third ot the crown. Unmanned aerial vehicle (UAV)-based hyperspectral imaging is an effective technique for forest health surveying and monitoring. Young adults are brownish black in colour and become darker over time. 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. Forests. An adult Tomicus piniperda (Linnaeus), a pine shoot beetle. They are able to fly, reside in trees and can be found at many altitudes around the world. These individuals then move back into the trunks to construct new galleries and to lay a second batch of eggs. Most species are attacked, but only the non-native Scotch pine (Pinus sylvestris) seems to suffer badly. An adult Tomicus piniperda (Linnaeus), a pine shoot beetle.
