Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer
Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer
The Great Lakes Entomologist
Naturally occurring predator and parasitoid communities are well known to respond to multiple scales of environmental heterogeneity within and around agroecoystems, yet our understanding of which scales are most influential on different functional guilds of enemies is limited. Using vote-counting methodology, we synthesized the results from 40 empirical studies that observed how natural enemy richness, diversity, or parasitism rate is affected by environmental heterogeneity at a local scale (e.g. a focal field), an intermediate scale (e.g. habitat in immediate proximity of a focal field), and landscape scale (e.g. habitat within >200 m radius around focal field). Heterogeneity at all scales …

The white-mold gall midge, Karshomyia caulicola Coquillett, was documented in association with soybean, Glycine max (L.) Merr., infected with the fungus Sclerotinia sclerotiorum (Lib.) de Bary. This mycetophagous cecidomyiid appears widespread in the northern soybean producing region, with confirmed detections from Minnesota, North Dakota and Québec. Though likely not a pest of soybean plants, the presence of K. caulicola in soybean fields may complicate identification, population assessment and decision making for soybean gall midge, Resseliella maxima Gagné, which is a recently described pest of soybean. Here, we provide an overview of the known biology and distribution of K. caulicola and …
