Pheromone trap captures of Helicoverpa zea (Boddie) and Heliothis virescens (F.) from 2002 - 2005 were used to examine the distribution of these species across a multiple crop environment in southeast Arkansas. The greatest number of H. virescens moths was collected during 2003, but densities were low compared with H. zea throughout the study. Overall, fewer H. virescens moths were captured next to Bt corn and Bt cotton than next to nonBt cotton and early-maturing soybean. A significant relationship was not detected between pheromone trap captures of H. virescens and the percentage of these moths that fed on cotton as larvae. More H. zea moths were captured in traps located next to Bt corn and nonBt corn during the month of June than in traps located next to cotton, sorghum, or soybean, whereas traps located adjacent to early- and late-maturing varieties of soybean, Bt cotton, nonBt cotton, and grain sorghum captured greater numbers of moths than those traps located next to corn during July. Therefore, the distribution of H. zea appeared to be influenced by corn acreage during the month of June. Later in the season, this species was widely distributed across the agricultural landscape. Compared with 2 other regions of AR, fewer H. zea moths were captured during the month of June and more H. virescens moths were captured during August in Mississippi Co., an area of intense cotton production.
