The objective of this study was to evaluate system level management effects on soil and foliar arthropod abundance and diversity in corn and soybean. Our field experiment was a completely randomized block design with three replicates for five farming systems which included: Conventional clean till, conventional long rotation, conventional no-till, organic clean till, and organic reduced till. Soil arthropod sampling was accomplished by pitfall trapping. Foliar arthropod sampling was accomplished by scouting corn and sweep netting soybean. Overall soil arthropod abundance was significantly impacted by cropping in corn and for foliar arthropods in soybeans. Conventional long rotation and organic clean till systems were highest in overall soil arthropod abundance for corn while organic reduced till systems exceeded all other systems for overall foliar arthropod abundance in soybeans. Foliar arthropod abundance over sampling weeks was significantly impacted by cropping system and is suspected to be the result of in-field weed and cover crop cultivation practices. This suggests that the sum of management practices within production systems impact soil and foliar arthropod abundance and diversity and that the effects of these systems are dynamic over the cropping season. Changes in diversity may be explained by weed management practices as sources of disturbance and reduced arthropod refuges via weed reduction. Furthermore, our results suggest agricultural systems lower in management intensity, whether due to organic practices or reduced levels of disturbance, foster greater arthropod diversity.}, number={4}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Adams, Paul R., III and Orr, David B. and Arellano, Consuelo and Cardoza, Yasmin J.}, year={2017}, month={Aug}, pages={771–783} }

Morphological studies with light microscopy and scanning electron microscopy, mating tests with reference strains, as well as molecular analyses of the near-full-length small subunit rRNA gene (18S) and D2-D3 expansion segments of the large subunit rRNA gene (28S) identified this isolate asPristionchus aerivorus. ExposedGallerialarvae were killed within 48 h and high numbers of nematodes were recovered from the cadavers about 5 days later. Preliminary tests revealed that this nematode is capable of infecting at least two other insect species (Helicoverpa zeaandTenebrio molitor) under laboratory conditions. The status of the genusChroniodiplogasteris discussed and confirmed as a junior synonym ofPristionchusbased on morphological observation and molecular phylogenetic analysis.}, journal={NEMATOLOGY}, author={Ye, Weimin and Yu, Qing and Kanzaki, Natsumi and Adams, Paul R. and Cardoza, Yasmin J.}, year={2015}, pages={567–580} }
