January 2009 Newsletter For Alumni and Friends Gassmann Hired as New Corn Entomologist I joined the Department of Entomol- ogy at Iowa State University in Janu- ary 2008. This was not the easiest time of year to leave sunny Tucson, Arizona where I had been working as an Assis- tant Research Scientist in the University of Arizona’s Department of Entomol- ogy. Despite the cold, however, I am delighted to be in Iowa again. I was born and raised in Dubuque County, where my family has deep roots. Vis- its to the farms of relatives and family friends filled much of my early years and gave me a strong affinity toward Iowa agriculture.

Lewis, a former research leader with the USDA- ARS and current Chair of entomology, was recently elected Fellow of the Entomological Society of America. Les is a recognized national and international leader in research on diseases of insect pests of corn, and on multi- trophic relationships between insects, insect pathogens, ben- eficial insects, and plants. His work to define relationships of insect pathogens, macrobiological control organisms, and chemical insecticides contributed significantly to the field of integrated pest management. This work included the definition of a unique tritrophic relationship with Beauveria bassiana, the corn plant, and the European corn borer.

Corylus avellana, simple sequence repeats, SSRs, DNA fi ngerprinting, genetic diversity ABSTRACT. Three microsatellite-enriched libraries of the european hazelnut (Corylus avellana L.) were constructed: library A for CA repeats, library B for GA repeats, and library C for GAA repeats. Twenty-fi ve primer pairs amplifi ed easy-to-score single loci and were used to investigate polymorphism among 20 C. avellana genotypes and to evaluate cross-species amplifi cation in seven Corylus L. species. Microsatellite alleles were estimated by fl uorescent capillary electrophoresis fragment sizing. The number of alleles per locus ranged from 2 to 12 (average = 7.16) in C. avellana and from 5 to 22 overall (average = 13.32). With the exception of CAC-B110, di-nucleotide SSRs were characterized by a relatively large number of alleles per locus (≥5), high average observed and expected heterozygosity (Ho and He > 0.6), and a high mean polymorphic information content (PIC ≥ 0.6) in C. avellana. In contrast, tri-nucleotide microsatellites were more homozygous (Ho = 0.4 on average) and less informative than di-nucleotide simple sequence repeats (SSRs) as indicated by a lower mean number of alleles per locus (4.5), He (0.59), and PIC (0.54).

  • The Effects of Winter Moth Defoliation on Forest Growth and Production Inferred from Satellite Imagery and Dendrochronology
    The effects of winter moth defoliation on forest growth and production inferred from satellite imagery and dendrochronology Erin Gleeson, Rhodes College 2000 North Parkway, TN 38112 Co-authors: Christopher Neill and Greg Fiske Woods Hole Research Center 149 Woods Hole Road, Falmouth, MA 02540 Gleeson 1 Abstract Forest disturbances are events that can cause change in the structure and composition of a forest ecosystem. Insect outbreaks may be a consequence of climate change, and could create unexpected dynamics in nature. Recently, and invasive pest from Europe, called the winter moth, has invaded Massachusetts and most of New England. The winter moth causes widespread defoliation by stripping the leaves off of all deciduous trees. I attempted to use remote sensing satellite data from MODIS, to classify sites that had experienced heavy defoliation and sites that had experienced little to no defoliation. Then, by looking at radial increment growth in tree cores, I created estimates of forest biomass growth, which I used as a model to try and study the effects of winter moth defoliation on greater areas of land. I found that defoliation from the winter moth has a large effect on tree ring width and overall tree growth because of how time period (pre and post winter moth) at each treatment affected ring width increment. The winter moth also reduced carbon storage in southeastern Massachusetts by around 51%. Clearly there are serious implications for an insect outbreak like this one, and measures, such as biological control by releasing natural parasitic enemies of the winter moth are being utilized. Climate change and a shift towards warmer global temperatures are predicted to increase the spread and severity of winter moth defoliation, and it is important that we think about future studies, and how we can control the reintroduction and spread of invasive insects that cause so much harm to ecosystem services and native ecosystem dynamics.

Accurate estimates of forest biomass are essential for several purposes, ranging from carbon accounting and ecological applications to sustainable forest management. There are, however, critical steps for mapping aboveground forest biomass (AGB) based on optical satellite data with an acceptable degree of accuracy, such as selecting the proper statistical modeling method and deriving spectral information from imagery, at known field locations. We compare nine modeling techniques including parametric, semiparametric, and nonparametric methods for remotely estimating AGB based on various spectral variables derived from Landsat 8 Operational Land Imager (OLI).

Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, 119071 Moscow, Russia; [email protected] (A.O.B.); [email protected] (M.J.O.-B.) * Correspondence: [email protected] Abstract: Emerald ash borer (EAB), Agrilus planipennis, native to East Asia, is an invasive pest of ash in North America and European Russia. This quarantine species is a threat to ash trees all over Europe. Survey in ten provinces of European Russia in 2019–2020 showed that EAB had spread faster and farther than was previously thought. The new infested sites were first detected in St. Petersburg (110–120 km from the EU border: Estonia, Finland) and Astrakhan Province (50 km from the Kazakhstan border). The current range of EAB in Europe includes Luhansk Province of Ukraine and 18 provinces of Russia: Astrakhan, Belgorod, Bryansk, Kaluga, Kursk, Lipetsk, Moscow, Orel, Ryazan, Smolensk, St. Petersburg, Tambov, Tula, Tver, Vladimir, Volgograd, Voronezh, and Yaroslavl. Within these, only seven quarantine phytosanitary zones in five provinces are declared by the National Plant Protection Organization of Russia. EAB was not found in the regions along the Middle Volga: Mari El, Chuvash and Tatarstan republics, Nizhny Novgorod, Samara and Saratov Citation: Volkovitsh, M.G.; provinces. The infested sites in St. Petersburg and in the Lower Volga basin are range enclaves Bie´nkowski,A.O.; separated from the core invasion range by 470 and 370 km, correspondingly.
