fter a long, hot summer, fall is finally here, offering hope of rain and some cooler temperatures. Keep in mind that fall is the time to plant. The temperature relief has significantly stimulated the work environment for landscapers, both local and out of state, and market activity is picking up conclusive to the digging and shipping season being upon us. The summer trade shows proved promising for spring orders, as well as producing a good number of requests for bid submissions. Along with winter shows being just around the corner, the Mid-States Horticultural Expo will follow closely along, at the newly scheduled date of January 28–29 in Louisville, Kentucky. This show offers a wonderful opportunity to secure late orders and orders from garden centers that must stock inventory for spring and summer sales. Our economic concerns continue to grow, and questions continue to mount as new laws governing small businesses are elaborated upon in Congress. We all have an obligation to our profession to stay informed and write to our congressional representatives, explaining our position as American ag-based businessmen and women and to voice our opinions and concerns as business owners and employers. Adolf Hitler once said, “What luck for leaders that men do not think.” We must be educated and prepared for what lies ahead and do what we can to hold our position.

THE CAMPHOR SHOT BORER… Tennessee’s New Invasive Ambrosia Beetle A PEST WITH POTENTIAL TO AFFECT OUR NURSERY AND LANDSCAPE INDUSTRIES By Jason Oliver, Nadeer Youssef and Joshua Basham, Tennessee State University, Otis L.

FALL 2010
The
camphor shot borer (Xylosandrus mutilatus [Blandford]) (CSB) was first detected in the United States in Oktibbeha County, Mississippi, in 1999 and is known to occur in Alabama, Florida, Tennessee and Texas. A native to Asia, the CSB probably entered the U.S. by transport in some type of wood product, similar to other ambrosia beetle introductions. Nursery stock and firewood are other potential routes for CSB movement. The CSB was first detected in Wayne County, Tennessee on April 25, 2008, and in Dickson County on May 5, 2008. During follow-up trap studies in 2009, the CSB was recovered in Coffee, Hardin, Hickman, Macon, McNairy, Montgomery, Perry, Putnam, Shelby and Williamson counties. The borer was found in Davidson County during spring 2010. We discovered the CSB attacking sweet bay magnolia at the Otis L. Floyd Nursery Research Center on April 15, 2010, which is the first report of CSB in Warren County.
CSB plant susceptibility The CSB is a member of the genus Xylosandrus, which is notorious for its nursery-attacking species. The other Xylosandrus species found in Middle Tennessee include the granulate ambrosia beetle (formerly Asian ambrosia beetle) (X. crassiusculus) and the black stem borer (X. germanus). Granulate ambrosia beetle and black stem borer frequently damage nursery crops in Middle Tennessee and have proven difficult to manage. It is unclear at this time if the CSB will become problematic for Tennessee nursery growers. CSB has many reported plant hosts (see Table 1). Sweetgum appears to be highly susceptible to attacks. In Alabama and Mississippi, CSB attacks occurred on stressed plants with crown dieback, herbicide injury, growing in poorly drained soil, nursery containers, damage from prescribed burns or deliberate trunk
girdling by researchers. Any condition that stresses plants could make them susceptible to CSB attack, including attacks by other ambrosia beetles. Many ambrosia beetle species are attracted to ethanol (i.e., drinking alcohol), which is often used to bait ambrosia beetle traps. Researchers believe ethanol is released when trees undergo stress. CSB was first detected at the Nursery Research Center attacking sweet bay magnolia that had been deliberately injected with ethanol, and the borer was also found attacking other ethanol-injected tree species in early May (Table 1), which suggests this species is attracted to stressed trees.
CSB biology The biology of the CSB is similar to other ambrosia beetles. Female borers fly to new hosts and bore into the trunk, creating a “shot hole” on the surface (Photo 1e). Unlike the granulate and black stem borer, which often bore straight into the trunk, the CSB usually bores a short horizontal tunnel and then creates a long (0.4" to 1.6") vertical tunnel (Photo 1f). The chambers formed by these tunnels are also called “galleries.” Adult borers inoculate the chamber with ambrosia fungi, which serves as food for the female and her developing progeny. New borers develop from egg to adult in about five to six weeks. Males typically die in the gallery, while females may remain in the gallery to over-winter or emerge and begin attacking new plants. In Mississippi, CSB flight began in March, was high from April to June (peaking in April), had a second smaller peak in August, and ended in September. In Tennessee, based on timing of CSB attacks in spring 2010, we know CSB definitely flies in April and May.
Identifying CSB tree attacks Symptoms of CSB attacks are similar to those of other ambrosia beetles and may include wilting and branch dieback.
Camphor shot borer images showing: (1a) adult borer side profile; (1b) side profile with thorax and abdomen measurements; (1c) adult borer top view; (1d) adult boring into a tree; (1e) gallery entrance size; (1f) an infested branch cut in half, revealing a short horizontal entrance and a long vertical gallery; (1g) inserting a 5/64" drill bit into a gallery entrance (the black ring has been added for visual reference and is not an identifying mark associated with the camphor shot borer); and (1h) gallery opening with borer blocking the entrance with its abdomen tip.
The CSB is one of the largest ambrosia beetles in North America; therefore it produces a large shot hole (0.078"). A 5/64" drill bit will fit into the entrance of a CSB gallery and is a quick way to check for approximate hole-size in the field (Photo 1g). The next largest drill bit size (i.e., 3/32") did not fit into the CSB galleries we checked. The CSB is not reported to produce toothpick-like strands of frass from the trunk, which are commonly seen with granulate ambrosia beetle and black stem borer. The tree may also have sap stains from the site of attack, and the gallery inside the tree may have dark stains from the ambrosia fungi. CSB will often plug the entrance hole with their body, possibly to defend developing larvae from natural enemies (Photo 1h). Although CSB is a large ambrosia beetle, it prefers to attack small-diameter tree branches (0.79" or less) and higher on the tree (above 1.6'). The trees we have seen attacked at the Nursery Research Center have been hit at about chest height. The preference of CSB for smaller-diameter stems increases the concern that CSB could be a pest of both nursery and landscape trees. It is also conceivable that CSB may be attacking the branch tips of larger forest and landscape trees, but this has not been proven. When scouting nursery stock for new CSB galleries, especially susceptible hosts like sweetgum, you should focus your search on smaller branches near chest-level height.
Identifying CSB To determine if CSB is attacking your trees, use a knife to carefully whittle the beetle from the gallery. Lopping the branch near the gallery entrance may facilitate CSB extraction with a knife. Unlike other ambrosia beetles, adult female CSB have an unusually squashed abdomen (Photos 1a–c). The borer’s abdomen is shorter in length than the thorax (Photo 1b). Depending on your eyesight, the compressed abdomen can be seen without the aid of a hand lens. Members of the genus Xylosandrus, like CSB, have a gap between the base of the front pair of legs, which can be viewed with a microscope (take the borer to your county Extension office for assistance).

The camphor shot borer, like other Xylosandrus species, has a broad host range, which undoubtedly includes more plant species than listed in this table.
b
Some of these plant species may not occur in the U.S. However, other plants in the same genus or family that do occur in the U.S. could be susceptible to the camphor shot borer.
c
Plants labeled with ‘TN’ were attacked by CSB at the Nursery Research Center. These plants were injected with ethanol, and therefore, may not be normal CSB hosts. However, CSB is willing to attack them following ethanol injection.

for an ambrosia beetle, has a compressed abdomen, black color and a gap between the base of the front legs, it is most likely CSB.
CSB management It is presently unknown if insecticides will effectively manage CSB. Few treatments are likely to be effective after CSB have entered the tree. Preventative sprays may provide some benefit. Permethrin has been the most effective treatment for other problem ambrosia beetles, but it has not been tested against CSB. Spray treatments should be thoroughly applied to the upper trunk and branches where CSB prefers to attack. Destruction of plants shortly after infestations are detected may reduce future CSB emergence at the nursery site. However, the CSB can reportedly fly about one to two miles per year, so local destruction of infested plants may have little effect at preventing attacks from surrounding areas. Destruction of infested plant materials, however, is important for preventing the human-assisted spread of CSB with nursery and landscape materials. C

(Above) Photo 2. ‘Munchkin’ matures to a medium-size shrub (3' high and 4-1/2' wide).
The
U.S. National Arboretum recently released two new oakleaf hydrangea cultivars. ‘Ruby Slippers’ and ‘Munchkin’ are the first releases of the hydrangea-improvement program at the U.S. National Arboretum’s McMinnville (Tennessee) worksite, which is located at the Tennessee State University Otis Floyd Nursery Crop Research Center. Both cultivars are well suited for use as specimen plants, in mass plantings or in the shrub border. Because of their small size, they are particularly useful in small residential landscapes. ‘Ruby Slippers’ originated from a controlled hybridization between ‘Pee Wee’ and ‘Snow Queen’. In 7 years, it has grown to 3-1/2' high and 5' wide. In early summer, ‘Ruby Slippers’ is covered with 9" long inflorescences that are held upright above the foliage. Flowers open white, but quickly turn pale pink and then deepen to rose. ‘Munchkin’ originated from openpollinated seed of ‘Sikes Dwarf’. In 9 years, it has grown to 3' high and 4-1/2' wide. In early summer, ‘Munchkin’ produces abundant, 6-1/2" long inflorescences that are held upright above the foliage. Flowers open white and gradually turn medium pink. Both cultivars are hardy in USDA zones 5 to 8 and can be grown in full sun or light shade. Plants are readily propagated in the nursery from softwood cuttings using 4000 ppm IBA, with rooting occurring within four to six weeks. Prior to their release, ‘Ruby Slippers’ and ‘Munchkin’ were both evaluated by cooperators in Alabama, Florida, Georgia, Illinois, Kentucky, Maryland, Mississippi, Missouri, New Jersey, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and Washington. Plants were distributed to cooperating nurseries for evaluation in 2006 and 2007, and for stock increase in 2008. The U.S. National Arboretum does not have stock plants of ‘Ruby Slippers’ or ‘Munchkin’ available for general distribution, but can provide a limited number of cuttings to interested propagating nurseries. The U.S. National Arboretum can also provide a list of propagating nurseries offering these plants for sale. Requests for this list should be addressed to: Dr. Sandra Reed, U.S. National Arboretum, 472 Cadillac Lane, McMinnville, TN 37110, or sandra.reed@ ars.usda.gov. Supplies of both cultivars are very limited at this time, but should increase in the next year or so. C

Meet Amy Fulcher, Nursery Crop Specialist Coming Soon to the University of Tennessee!
H
ello, Tennessee! I have recently been hired as a faculty member in the Department of Plant Sciences in the Sustainable Ornamental Plant Production and Landscape Management position at the University of Tennessee. My official start date is November 1, 2010. For the past 20 years, I have worked in some segment of the green industry, holding positions in retail, nursery and greenhouse operations, and even a part-time stint in urban forestry. Most of my professional experience has been with the Cooperative Extension Service in Kentucky. Since 2002, I have been an Extension Associate for Nursery Crops, focusing on woody plant production, which is my main area of expertise. When I arrive in Knoxville, I am looking forward to getting to know the members of the industry, better understanding the issues and constraints the Tennessee green industry is facing, and then developing and securing funding for an Extension and applied-research program that addresses those
issues. I enjoy working collaboratively and hope to work with UT Extension Specialists, as well as professionals researching nursery crop issues in Tennessee and throughout the Southeast. Learning about the Extension needs of Tennessee’s green industry will be one of my biggest priorities. From my years of experience, I have developed a fairly broad-based applied-research program. For instance, I have investigated (among others) compost and alternative substrates for container production, pot-in-pot production, host-plant resistance to diseases and insects and developing irrigation technology that can reduce water consumption without sacrificing plant growth or crop quality. These projects developed from my interaction with growers and a common philosophy of working together to solve an industry challenge. Probably the most important thing to know about me is that I enjoy working with plants, but I enjoy helping growers with their plant problems even more! C
