Does agricultural landscape structure affect parasistism and parasitoid diversity?

Synopsis: This study evaluates whether previous observations of a higher percentage of parasitism and parasitoid diversity in a complex agricultural landscape, relative to a simple landscape, represent a general phenomenon. Rates of parasitism and parasitoid diversity of the armyworm (Pseudaletia unipuncta) were assessed in three replicate (Onondaga, Ingham, and Benton) regions in southern Michigan. Within each region, a simple landscape (primarily cropland) and a complex landscape (cropland intermixed with mid and late successional noncrop habitats) were identified through analysis of aerial photographs. In each landscape, three maize fields were selected, and second to fourth instar P. unipuncta were released...

Blood Parasite Infection Data from Northwestern Crows (Corvus caurinus), Alaska, 2007-2008

This data set consists of two tables associated with a study of Haemosporidian parasite infection in Northwestern Crows (Corvus caurinus) sampled at six locations throughout southcentral and southeast Alaska in 2007-2008. The first table contains species, location, banding, and morphometric data for all samples. The second table contains results from heamosporidian parasite screening of crow blood samples using molecular techniques. Genomic DNA was extracted from blood samples and screened for the presence of Haemoproteus, Plasmodium, and Leucocytozoon blood parasites using a nested-PCR method. Parasite genetic data is provided as GenBank accession numbers for any samples that tested positive for haemosporidian...

Traits and Factors Catalog (TRAFAC): Non-native insects of North American forests

These data were compiled in support of the "Predicting the next high-impact insect invasion: Elucidating traits and factors determining the risk of introduced herbivorous insects on North American native plants" project supported by the U.S. Geological Survey John Wesley Powell Center for Analysis and Synthesis, as well as the "Forecasting high-impact insect invasions by integrating probability models with i-Tree from urban to continental scales" project supported by the USDA Forest Service National Urban and Community Forestry Advisory Council. The project working group compiled data for non-native, tree-feeding insects in North America. Data were synthesized from existing resources for a variety of insect traits,...
