The Great Lakes Entomologist

(excerpt)

Tiphia vernalis Rohwer is native to China, Japan, and Korea where it is an external parasite of Popillia spp. (King 1931). It was released into the United States from China and Korea during the mid-1920s through early 30s (Fleming 1968). After it became established in the United States, releases were made from domestic sources beginning in 1931 (King et al. 1951). Tiphia vernalis was released into Ohio sporadically during 1936-1953 (King et al.1951). Tiphia vernalis has been reported parasitizing Popillia spp. (P. quadriguttata (Fabricius) in Korea; P. chinensis (Frivaldsky) and P. formosana (Arrow) in China; and P. japonica ...

Second Location For Two Rare Odonata In Ohio, Nannothemis Bella And Ladona Julia, (Odonata: Libellulidae) Discovered At Singer Lake Bog, Summit County, Ohio., Robert C. Glotzhober, Eric Chapman

The Great Lakes Entomologist

Previously the dragonflies (Odonata, Libellulidae) Ladona julia and Nannothemis bella were known in Ohio from only one extant population each: L. julia from extreme northwest Ohio in Williams County and N. bella from west-central Ohio in Champaign County. During the summer of 2000 populations of each of these species were found in close proximity to each other at Singer Lake, a wetlands complex in southern Summit County in northeastern Ohio. This new location is also home to a population of another rare Ohio dragonfly, Dorocordulia libera (Odonata, Corduliidae) that was discovered during 1999. The Singer Lake wetlands are proving to ...

Commentary On Ametropus Species (Ephemeroptera: Ametropodidae) In North America, W. P. McCafferty 2018 Purdue University

Commentary On Ametropus Species (Ephemeroptera: Ametropodidae) In North America, W. P. Mccafferty

The Great Lakes Entomologist

Ametropus albrighti is shown to be a junior subjective synonym of A. neavei, n. syn. Ametropus neavei sensu lato demonstrates stable structural characteristics with respect to male genitalia and larval morphology, whereas degree of maculation and therefore abdominal patterning varies both among populations and within populations. Ametropus ammophilus is distinctive, and the two North American species are apparently allopatric based on known distributions, which are reviewed.

Loss of biodiversity and degradation of ecosystem services from agricultural lands remain important challenges in the United States despite decades of spending on natural resource management. To date, conservation investment has emphasized engineering practices or vegetative strategies centered on monocultural plantings of nonnative plants, largely excluding native species from cropland. In a catchment-scale experiment, we quantified the multiple effects of integrating strips of native prairie species amid corn and soybean crops, with prairie strips arranged to arrest run-off on slopes. Replacing 10% of cropland with prairie strips increased biodiversity and ecosystem services with minimal impacts on crop production. Compared with ...


Producing Food, Feed And Energy: How Can Agriculture Do It All?, Emily Heaton, Lisa Schulte-Moore, Matt Helmers, Matt Liebman 2018 Iowa State University

Producing Food, Feed And Energy: How Can Agriculture Do It All?, Emily Heaton, Lisa Schulte-Moore, Matt Helmers, Matt Liebman

Matthew J. Helmers

Sustainable intensification of agricultural systems has been suggested—in addition to reducing waste and changing consumption habits—as a way to increase food, feed, fuel, and fiber security in the 21st century. Here we describe three primary strategies of agricultural intensification—conventional intensification, temporal intensification, and spatial intensification—and how they can be used to manage and integrate food and second-generation (2G) crop portfolios. While each strategy has individual merits, combining them to meet case-specific targets may achieve optimum results. Multiple experiments and examples from Iowa, USA illustrate the potential of combining these approaches for agroecological intensification that can provide ...


Nutrient Reduction Strategy: One Farm, Many Practices, Matthew J. Helmers 2018 Iowa State University

Nutrient Reduction Strategy: One Farm, Many Practices, Matthew J. Helmers

Matthew J. Helmers

With the release of the Iowa Nutrient Reduction Strategy (2013) in early 2013 there has been increased interest in what practices can be utilized by farmers to reduce nutrient export to downstream water bodies. As highlighted by the ISU Extension and Outreach Special Publication 235 (2013) there are many in-field, land use, and edge-of-field practices that have potential to reduce nutrient export. However, to reach the nutrient load reduction goals of 45% on both nitrate-N and phosphorus will require a combination of practices. As a result, there is a need to examine individual fields or small watersheds considering the range ...

Effects Of Nitrogen Application Timing And Source On Nitrate-Nitrogen Leaching And Crop Yields, Ainis Lagzdins, Matthew J. Helmers

Matthew J. Helmers

Subsurface drainage systems have been intensively installed in the Midwest to enhance agricultural production by removing excess water from naturally poorly drained and somewhat poorly drained agricultural soils. However, despite positive aspects, numerous studies have reported artificial subsurface drainage as one of the primary pathways for nitrate-nitrogen (nitrate-N) loss from agricultural fields to surface water.


Impacts Of 4r Nitrogen Management On Drainage Water Quality, Matthew J. Helmers 2018 Iowa State University

Impacts Of 4r Nitrogen Management On Drainage Water Quality, Matthew J. Helmers

Matthew J. Helmers

Much of the U.S. Corn Belt is characterized by relative flat, poorly-drained areas which with extensive subsurface drainage, have become some of the most valuable and productive agricultural land in the world. However, this is not without consequences. Nitrate-N loss from these systems is of particular concern due to its potential adverse impacts on both public health and ecosystem function. In addition to the potential local impacts on receiving waters in the Corn Belt, nitrogen loads from the region are suspected as a primary contributor to hypoxia in the Gulf of Mexico. For nearly 30 years Iowa State University ...


Drainage Design For Improved Profits And Water Quality, Matthew J. Helmers, Greg Brenneman 2018 Iowa State University

Drainage Design For Improved Profits And Water Quality, Matthew J. Helmers, Greg Brenneman

Matthew J. Helmers

Subsurface drainage systems are an important component of agricultural production systems in many areas of Iowa. However, these drainage systems have been shown to deliver nitrate-N to downstream waterbodies. So, while subsurface drainage is important for crop production we also need to consider the design of these systems to minimize nitrate-N loss. Use of drainage water management in the design and operation of subsurface drainage systems is one potential method to reduce nitrate-N loss.

Modeling The Impacts Of Climate Change On Nitrogen Losses And Crop Yield In A Subsurface Drained Field, Zhaozhi Wang, Qhiming Qi, Lulin Xue, Melissa Bukovsky, Matthew J. Helmers

Matthew J. Helmers

The effect of climate change on crop production and nitrate-nitrogen (NO3-N) pollution from subsurface drained fields is of a great concern. Using the calibrated and validated RZWQM2 (coupled with CERES-Maize and CROPGRO in DSSAT), the potential effects of climate change and elevated atmospheric CO2 concentrations (CO2) on tile drainage volume, NO3-N losses, and crop production were assessed integrally for the first time for a corn-soybean rotation cropping system near Gilmore City, Iowa. RZWQM2 simulated results under 20-year observed historical weather data (1990–2009) and ambient CO2 were compared to those under 20-year projected future meteorological data (2045–2064) and elevated ...


Electrical Stimulation For Enhanced Denitrification In Woodchip Bioreactors: Opportunities And Challenges, J. Y. Law, Michelle L. Soupir, D. Raj Raman, T. B. Moorman, Say K. Ong 2018 Iowa State University

Electrical Stimulation For Enhanced Denitrification In Woodchip Bioreactors: Opportunities And Challenges, J. Y. Law, Michelle L. Soupir, D. Raj Raman, T. B. Moorman, Say K. Ong

D. Raj Raman

Woodchip bioreactors are being implemented for the removal of nitrates in groundwater and tile water drainage. However, low nitrate removals in denitrifying woodchip bioreactors have been observed for short hydraulic retention time (HRT) and low water temperature (°C). One potential approach to improve woodchip bioreactor performance is to provide an alternative and readily available electron source to the denitrifying microorganisms through electrical stimulation. Previous work has demonstrated the capability of bio-electrochemical reactors (BER) to remove a variety of water contaminants, including nitrate, in the presence of a soluble carbon source. The objective of this study was to evaluate the denitrification ...

Sow Lying Behaviors Before, During And After Farrowing, F. Lao, T. M. Brown-Brandl, G. Teng, Kai Liu, Hongwei Xin

Hongwei Xin

Piglet pre-weaning mortality remains a considerable challenge for the swine industry, representing one of the key areas where animal well-being and economical interest coincide. Sows and piglets carry out a complex series of behaviors during the farrowing/lactation period. These behaviors during the first few days after parturition are extremely important for piglet survival, and they can be greatly impacted by the farrowing system, environment, and/or management. The risk of sow crushing is much greater for piglets when the sow changes her postures. Limited studies have investigated the effects of environment on sow’s posture changes or basic understanding ...

The total heat and moisture production (THP and MP) values of pigs that are currently published in ASHRAE standards are from data collected in either the 1970s (nursery piglets) or the 1950s (growing-finishing pigs). These series of studies, conducted to systematically update the THP and MPstandards, includes a series of four indirect calorimeter studies (nursery, growing-finishing gilts, and finishing barrows), and six facility-level studies (nursery, growing, early finishing, late finishing, gestating gilts, and farrowing sows and litters). The studies were completed at various temperatures from thermal neutral to hot conditions, demonstrating the trends that HP and feed intake decreased while ...
