Classical biological control could have a major environmental cost if introduced natural enemies colonize and disrupt native systems. Although quantifying these impacts is difficult for systems already colonized by natural enemies, the a priori condi

The alternate host food–plant relationships of North American pest Lepidoptera were examined to better understand how the vegetational structure of agricultural landscapes may influence parasitoid populations and diversity and thus their potential

The importance of density dependence, aggregation and background density of seeds on intensity of seed predation in cereal fields were examined in central Netherlands. Four sequential 1-week trials were conducted from 9 July to 8 August 2001 and lamb

Fall transplanted `Commander' broccoli (Brassica oleracea Botrytis group) yield in mulches formed from the residues of killed cowpea (Vigna unquiculata), soybean (Glycine max), and velvetbean (Mucuna pruriens) cover crops was compared to yield in con

Temporal variations in the relationship between agricultural landscape complexity and parasitoid abundance were assessed in Ingham County, MI. The study site consisted of a 3.2 km ×13.9 km area including a complex and a simplified agricultural lands

Velvet bean has been used traditionally as a summer cover crop in the southeastern United States. We investigated the use of killed velvet bean as a cover crop mulch left on the soil surface before collard was transplanted in the fall. Control treatm

Weed seed predation by invertebrates and vertebrates was compared between a simple (large crop fields embedded in a matrix of widely scattered woodlots and hedgerows) and a complex (small crop fields embedded in a matrix of numerous hedgerows and woo

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 d

The influence of tree density (2 x 3, 1 x 2, and 0.5 x 1 m) and weed control (weedy vs. weed free) on the growth and branching architecture of Populus xeuramericana cv. Eugenei was examined in an experimental plantation in southwestern Michigan, U.S.
