Lilac (Ash) Borer Pupal Skins Extrude from Trunk
Lilac (Ash) Borer Pupal skins extrude from trunk Name and Description—Podosesia syringae (Harris) [Lepidoptera: Sesiidae] Adult lilac (ash) borers are moths that vary in color from brown to yel- low to orange. They have clear wings with a span of about 1-1 1/8 inches (26-28 mm) and appear wasp-like (fig. 1). Larvae are about 1 inch (2.5 cm) long and are white with brown heads (fig. 2). Hosts—Ash and lilac Life Cycle—There is one generation per year. Mature borer larvae over- winter in tunnels under the bark. Adult moths emerge from March through June to lay eggs on the bark of host trees. The larvae bore into trunks and branches of the sapwood of trees during the summer. Galleries can be up to 6 inches (15 cm) long. Figure 1. Adult ash borer. Photo: Daniel Herms, Ohio State University, Bugwood.org. Damage—The mining of the larvae causes branch dieback (fig. 3). It can also lead to broken branches. The leaves on affected branches turn brown as the branch dies. Extensive mining can also lead to tree death. Entrances to lar- val mines often appear as sunken or cankered areas on the bark of the trunk or branch. Dark, moist sawdust can be found around the Figure 2. Ash borer larva. Photo: James Solomon, USDA Forest gallery entrance (fig. 4). Pupal Service, Bugwood.org. skin remaining in the bark is often also observed (fig. 5). Management—Avoid damaging trees—maintaining trees in good health reduces their susceptibil- ity to attack. There are chemical sprays that are highly effective at Figure 3.

By 2009, mortality of green, white, and black ash exceeded 99%, and ash seed production and regeneration had ceased. This left an orphaned cohort of saplings too small to be infested, the fate of which may depend on the ability of natural enemies to regulate EAB populations at low densities.

Emerald Ash Borer [Agrilus Planipennis (Fairmaire)] Lori R
Published by Utah State University Extension and Utah Plant Pest Diagnostic Laboratory ENT-171-14-PR August 2014 Emerald Ash Borer [Agrilus planipennis (Fairmaire)] Lori R. Spears, CAPS Coordinator • Ryan S. Davis, Arthropod Diagnostician • Ricardo A. Ramirez, Entomologist Do You Know? • The Emerald Ash Borer (EAB) is a recent invasive pest, and is considered to be one of the most destructive forest insects to ever invade the U.S. • EAB adults are very good fliers, but new infestations are primarily caused by people moving wood from infested areas. • New infestations are difficult to detect and damage may not be obvious for years. However, by then it may be too late – an EAB infestation is nearly always fatal to the tree. • EAB has not yet been reported in Utah. To help prevent the spread of EAB, avoid transporting Fig. 1. Emerald ash borer adult feeding on an ash leaf.1 firewood across county and state lines. merald ash borer (Order: Coleoptera: Family EBuprestidae) (EAB) (Figs. 1-2) is an exotic, invasive wood-boring insect that specializes on true ash species (Fraxinus spp.). EAB is native to parts of China, Korea, Japan, Taiwan, and small areas of Russia and Mongolia. EAB was first discovered in North America in June 2002 near Detroit, Michigan and Windsor, Ontario, and is thought to have arrived to North America via infested wood packing material. Evidence suggests that EAB is generally established in an area for several years before Fig. 2. Adults have a copper red or purple abdomen.2 it is detected. Since arriving in North America, EAB has been found in more than 20 mid-western and eastern a flattened body, and an iridescent purple abdomen states, killing tens of millions of ash trees.
