June 2016 1 THINGS to DO / THINGS to THINK ABOUT THIS MONTH Spring/early summer is here and the 2016 growing season is well underway. The predictable unpredictability of the weather has brought the typical challenges that we face on an annual basis. Hopefully the majority of you are untouched or unaffected by the quirky weather that has been observed. Hopefully you’ve gotten some of the rain that has fallen across the Prairies. To combat or counteract the unpredictability of the weather, welcome to another ever-so-predictable edition of Hort Snacks. The content isn’t always predictable, but the arrival of it is. In this edition, you’ll notice a theme. And that theme is largely creepy/crawly. The season of insect wildlife is upon us, and to prepare you (and perhaps some of your customers) for identifying and dealing with some of those pests, you’ll find some caterpillar-related resources. That doesn’t mean that there aren’t more things out there, but this is a start. Otherwise, please take a moment to look at the various bits and pieces that might be of interest to you. Regardless, we wish you all the best for your growing season. Stay in touch.

  • Feeding Rates of Warblers in Spring
    Condor85:139-150 G The Cooper Omithologd Society 1983 FEEDING RATES OF WARBLERS IN SPRING JEAN W. GRABER AND RICHARD R. GRABER ABSTRACT.-Populations of migrant warblers were correlated with populations of lepidopterous larvae in spring in a heavily forested area of southern Illinois. The birds appeared to feed entirely on these larvae, mostly taken from oaks. Estimates of grosscalorie intake indicated a positive energy balance for warblers in an area with larval biomass of 0.70 g per m3, and a negative balance in an area with biomass of 0.02 g per m3. Warblers chose either the smaller size classes (under 15 mm) of larvae, or the smaller species (especially leafrollers) out of proportion to their availability, but the birds’ positive energy balance was de- pendent upon an irruption of geometrids. Lepidopterous larvae constituted 75- 98% of the available foliage invertebrates, and other groupswere insufficient alone to support migrant populations. Larvae were about 80% water, and warblers ingested 1.2-1.7 times their own weight in larvae per day in order to attain gross caloric intake of 14.8-19.0 kcal per bird-day. Warblers in an area with insufficient food resourcesingested 7.2 kcal/day, and their behavior was consistent with a goal of energy conservation. Among the problems faced by migrants after principal study to make the observations re- a flight is that of finding adequatefood supplies ported here. to continue the migration, particularly as the landing area may be completely unknown to STUDY AREAS the birds. In Illinois the only measurementsof Our study area with extensive forest habitat migrant populationsin forest habitat have been was in Shawnee National Forest in southern those of Twomey (1945) and Calef (1953) who Illinois (88”3O’W, 37”28’N): mature upland found four to eight times more birds in elm- oak-hickory, and upland forest edge in Pope maple forest at the peak of migration in May County (57.2% forested).

  • Impacts of Native and Non-Native Plants on Urban Insect Communities: Are Native Plants Better Than Non-Natives?
    Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives? by Carl Scott Clem A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Key Words: native plants, non-native plants, caterpillars, natural enemies, associational interactions, congeneric plants Copyright 2015 by Carl Scott Clem Approved by David Held, Chair, Associate Professor: Department of Entomology and Plant Pathology Charles Ray, Research Fellow: Department of Entomology and Plant Pathology Debbie Folkerts, Assistant Professor: Department of Biological Sciences Robert Boyd, Professor: Department of Biological Sciences Abstract With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled with replacement of native plants by alien ornamental plants such as crepe myrtle, Bradford pear, and Japanese maple. Two projects were conducted for this thesis. The purpose of the first project (Chapter 2) was to conduct an analysis of existing larval Lepidoptera and Symphyta hostplant records in the southeastern United States, comparing their species richness on common native and alien woody plants. We found that, in most cases, native plants support more species of eruciform larvae compared to aliens. Alien congener plant species (those in the same genus as native species) supported more species of larvae than alien, non-congeners. Most of the larvae that feed on alien plants are generalist species. However, most of the specialist species feeding on alien plants use congeners of native plants, providing evidence of a spillover, or false spillover, effect.

  • Species on the Menu of a Generalist
    Molecular Ecology (2009) 18, 2532–2542 doi: 10.1111/j.1365-294X.2009.04184.x SpeciesBlackwell Publishing Ltd on the menu of a generalist predator, the eastern red bat (Lasiurus borealis): using a molecular approach to detect arthropod prey ELIZABETH L. CLARE,* ERIN E. FRASER,† HEATHER E. BRAID*, M. BROCK FENTON† and PAUL D. N. HEBERT* *Department of Integrative Biology, University of Guelph, Guelph, ON, Canada N1G2W1, †Department of Biology, University of Western Ontario, London, ON, Canada N6A 5B7 Abstract One of the most difficult interactions to observe in nature is the relationship between a predator and its prey. When direct observations are impossible, we rely on morphological classification of prey remains, although this is particularly challenging among generalist predators whose faeces contain mixed and degraded prey fragments. In this investigation, we used a poly- merase chain reaction and sequence-based technique to identify prey fragments in the guano of the generalist insectivore, the eastern red bat (Lasiurus borealis), and evaluate several hypotheses about prey selection and prey defences. The interaction between bats and insects is of significant evolutionary interest because of the adaptive nature of insect hearing against echolocation. However, measuring the successes of predator tactics or particular prey defences is limited because we cannot normally identify these digested prey fragments beyond order or family. Using a molecular approach, we recovered sequences from 89% of the fragments tested, and through comparison to a reference database of sequences, we were able to identify 127 different species of prey. Our results indicate that despite the robust jaws of L. borealis, most prey taxa were softer-bodied Lepidoptera.

    Final Technical Report Award: DE-FG02-06ER64232 Recipient: The Board of Regents of the University of Wisconsin System Project title: Impact of elevated CO2 and O3 on insect-mediated ecosystem processes in a northern deciduous forest Project PI: Richard L. Lindroth Date: Nov. 20, 2011 Project dates: July 1, 2006 – June 30, 2009, with no-cost extension through December 2010 Distribution limitation notices None Executive summary Rising concentrations of atmospheric CO2 and O3 are altering the structure and function of forest ecosystems. Herbivorous insects are the major consumers in temperate deciduous forests, with the capacity to dramatically alter tree growth (via outbreaks), forest community composition and ecosystem dynamics (e.g., nutrient cycling). Until recently, however, experimental quantification of the impacts of CO2 and O3 on canopy herbivore communities and rates of defoliation and nutrient flux has not been addressed. This research, conducted at the Aspen FACE (Free Air CO2 Enrichment) facility in northern Wisconsin, U.S.A., evaluated the independent and interactive effects of CO2 and O3 on 1) the abundance and diversity of forest canopy insect communities, and 2) rates of insect herbivory and transfer of material (leaf greenfall and insect frass) from the canopy to the forest floor. Results of studies of individual insects revealed that elevated CO2 and O3 influence the performance of individual species of damaging insect pests, but the magnitude of impact is influenced by both insect species and their host tree species. Censuses of canopy insects showed that some species were positively affected, some negatively affected, and some not affected by elevated CO2 and O3.
