Comparison of pitfall traps and litter bags for sampling ground-dwelling arthropods

Jarrad R. Prasifka, +4 more
- 01 Mar 2007 - 
TL;DR: Comparisons among pitfall traps, and litter bags placed above‐ or below‐ground indicated that above‐ground litter bags most frequently succeeded in collecting certain groups of arthropods associated with moisture and sheltered areas, including centipedes and beetle larvae.
Journal ArticleDOI

Utility of Ground Beetle Species in Field Tests of Potential Nontarget Effects of Bt Crops

Miriam D. Lopez, +3 more
- 01 Oct 2005 - 
TL;DR: Carabid collections indicate Harpalus pensylvanicus DeGeer is the best choice to sample based on its apparent ubiquity and abundance in Iowa and other corn-producing states, however, population levels were time-dependent, and composition of carabid communities differed between locations.
Journal ArticleDOI

Effects of insecticide exposure on movement and population size estimates of predatory ground beetles (Coleoptera: Carabidae)

Jarrad R. Prasifka, +3 more
- 01 Jan 2008 - 
TL;DR: The disagreement between laboratory and field results suggests mechanisms other than hyperactivity may better explain unusual changes in population size estimates.
Journal ArticleDOI

A single major QTL controls expression of larval Cry1F resistance trait in Ostrinia nubilalis (Lepidoptera: Crambidae) and is independent of midgut receptor genes

Brad S. Coates, +10 more
- 06 Aug 2011 - 
TL;DR: In this paper, the European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae), is selected for high levels of Cry1F resistance (>12,000-fold compared to susceptible larvae) and is capable of survival on transgenic hybrid corn.

Effects of Transgenic Bacillus thuringiensis Corn and Permethrin on Nontarget Arthropods 1

Denny J. Bruck, +4 more
TL;DR: Large- scale field studies arranged in randomized complete blocks were conducted in central Iowa, consistent with other studies that suggest nontarget impacts resulting from insecticides may be greater than those caused by Bt corn.
