Jan. 18, 2013 — Baited black traps in a pyramid shape attract significantly more brown marmorated stink bugs than other traps, according to U.S. Department of Agriculture (USDA) scientists. Evaluating stink bug responses to different visual stimuli may help manufacturers design better traps for monitoring the bugs.
Entomologist Tracy Leskey at the Agricultural Research Service (ARS) Appalachian Fruit Research Station in Kearneysville, W.V., focused on visual stimuli that can attract the stink bugs to traps that will help farmers monitor the level of infestation in their fields and orchards.
In field trials in 2009 and 2010, Leskey and her colleagues found that significantly more stink bug adults and juvenile bugs, called nymphs, were captured in the baited black pyramid traps than in other traps. The researchers also found that more adults and nymphs were captured in a trap placed on the ground than in a commercially available trap hung from a tree limb. [ … continue ]
