Ambrosia beetles include well-known invasive pests, but most species established 19 in non-native areas do not cause any significant impact. Here we report the recent invasion and 20 rapid spread of Ambrosiodmus minor in the Southeastern US. 21 Methods: We used a combination of a multi-year survey, literature data on fungal symbionts 22 from the beetle mycangia and in vitro bioassays of fungal competition, and extensive field 23 observations of wood colonization patterns. 24 Results. In less than seven years, A. minor abundance has increased many-fold in Florida. The 25 beetle is associated with an aggressive wood-rot fungus Flavodon ambrosius. Joint colonization 26 of wood by A. minor and F. ambrosius results in extensive white rot (lignin removal). The 27 invasion of this symbiosis may impact an ecosystem function previously considered not 28 influenced by non-native ambrosia beetles: wood decay. We suggest monitoring of the impact of 29 this invasion on native wood-inhabiting organisms, biomass degradation and the carbon cycle 30 throughout the region. -

Purdue University Name of Student: Department of Entomology Sean Tormoehlen Undergraduate Capstone Project Summary Name of Mentor: Dr. Matthew Ginzel Project Title: Seasonal flight activity of scolytine beetles associated with black walnut Introduction: Black walnut (Juglans nigra) is an important hardwood species in the Eastern United States because of its role in the environment and the contributions it makes to the economy. Black walnut trees help to reduce soil erosion and they provide a rich food source for a variety of wildlife including birds and squirrels. They are also known to produce juglone, an allelochemical, which suppresses growth of plants around the tree and alters fauna (Virginia Cooperative Extension). Black walnut is an important economical resource because of its desirable wood qualities and nut production. It is used in a wide variety of wood products including furniture, veneer, plywood panels, and gunstocks. These products bring in $21.4 million into Indiana’s economy annually and $325 million through annual U.S. exports. It is projected that the estimated value of black walnut in its native range is $569 billion (USFS 2002). Black Walnut trees are currently being challenged by thousand cankers disease. This disease is caused by a fungus, (Geosmithia morbida), that is associated with the walnut twig beetle (Pityophthorus juglandis). The main symptoms of thousand cankers disease are small cankers underneath the bark, on branches and the trunk, entry holes from the walnut twig beetle, and branch death (USDA Forest Service, 2013). Infection occurs when an adult walnut twig beetle emerges from a symptomatic tree and flies to a new black walnut tree where it bores into the bark introducing the fungus. -

Vectors of Dutch Elm Disease in Northern Europe

Kreutzwaldi 5, 51006 Tartu, Estonia; [email protected] (A.A.); [email protected] (R.D.) 2 Ilmar Süda FIE, Rõõmu tee 12-5, 50705 Tartu, Estonia; [email protected] * Correspondence: [email protected] Simple Summary: Dutch elm disease (DED) has been killing elms for more than a century in northern Europe; the trees’ health status has worsened substantially in recent decades. Elm bark beetles Scolytus spp. are vectors of DED. Our aim was to estimate the distribution range of elm bark beetles and to detect potential new vectors of DED agents in northern Europe. Beetles were caught with bottle traps and manually. Then DNA from each specimen was extracted and analysed by the third generation sequencing method. DED agents were detected on the following bark beetles for Europe: Scolytus scolytus,S. triarmatus, S. multistriatus, S. laevis, and on new vectors: Xyleborus dispar and Xyleborinus saxesenii. The spread of Scolytus triarmatus, S. multistriatus and Xyleborinus saxesenii has been remarkable for the last two decades, and S. triarmatus and X. saxesenii are relatively recent newcomers in the northern Baltics. The problem is that the more vectoring beetles there are, the faster spread of Dutch elm disease from tree to tree. Abstract: Potential Dutch elm disease vector beetle species were caught with pheromone bottle traps and handpicked in 2019: in total, seven species and 261 specimens were collected. -

DACS-P-01675 Florida Department of Agriculture and Consumer Services, Division of Plant Industry Charles H. Bronson, Commissioner of Agriculture Another Asian Ambrosia Bettle Established in Florida (Coleoptera: Curculionidae: Scolytinae: Xyleborini) Katherine E. Okins, [email protected], Cooperative Agricultural Pest Survey, Florida Department of Agriculture & Consumer Services, Division of Plant Industry Michael C. Thomas, [email protected], Taxonomic Entomologist, Florida Department of Agriculture and Consumer Services, Division of Plant Industry INTRODUCTION: The ambrosia beetle Xyleborinus andrewesi (Blandford) was recently collected in Ft. Myers, Lee County, Florida. Over 30 beetles were reared from a branch section taken from a sugar apple (Annona squamosa L.) tree. Xyleborinus andrewesi is widely distributed throughout the Old World tropics (Browne 1961). It is not native to the New World, but has been reported from Hawaii (Cognato and Rubinoff 2008), Cuba (Bright and Skidmore 2002), and Jamaica (Wood and Bright 1992). Surveying is needed to further assess establishment of X. andrewesi in Florida. Also reared from the same wood were two cerambycids (Leptostylopsis terraecolor (Horn) and Leptostylus transversus (Gyllenhal in Schoenherr) (both native species)) and four other scolytines (Xylosandrus crassiusculus (Motschulsky) and Xyleborinus saxesenii (Ratzeburg) (both introduced Asian species)), Xyleborus affinis Eichhoff and Hypothenemus squamosus (Hopkins) (both native species). IDENTIFICATION: Xyleborinus andrewesi is a small, reddish-dark brown, elongate-cylindrical beetle about 2 mm long. It is easily distinguished from the two other Florida species of Xyleborinus by the subacuminate elytra and rows of numerous strong, acuminate tubercles on the first and third interstriae (Fig. 1). BIOLOGY: Beetles lay eggs in newly felled green timber (Stebbing 1914), or in damaged or dying trees (Schedl 1962). -

Attracted to Avocado, Lychee, and Essential Oil Lures
Diversity of Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) Attracted to Avocado, Lychee, and Essential Oil Lures Paul E. Kendra1*, Jorge S. Sanchez1, Wayne S. Montgomery1, Jerome Niogret1, and Katherine E. Okins2 1USDA-ARS, Subtropical Horticulture Research Station, Miami, FL USA 2Florida Department of Agriculture and Consumer Services, DPI, CAPS, Gainesville, FL USA Field trapping studies conducted in Alachua and Marion Counties, Florida, for the redbay ambrosia beetle (Xyleborus glabratus) captured numerous non-target ambrosia beetles, providing information on species diversity and relative abundance. Traps (Lindgren funnels and sticky panels) baited with essential oil lures (manuka and phoebe) or freshly-cut bolts of avocado and lychee wood attracted 17 species of Scolytinae, including 5 species of Xyleborus. Xyleborus glabratus comprised 75% of the captures in a mixed pine-oak-swampbay forest with advanced stages of laurel wilt. The table below summarizes the species caught, representing four tribes within the Scolytinae subfamily, and their respective numbers captured over a three-month period (October-December 2009). Photos of most species are presented.
