Conservation Biological Control Of Western Bean Cutworm: Molecular Gut Content Analysis Of Arthropod Predators, Feeding Trials For Key Predators And Agricultural Surveys For Integrated Pest Management, Westen Ray Archibald
Department of Entomology: Dissertations, Theses, and Student Research
Western bean cutworm (WBC), Striacosta albicosta is a major pest of corn in western Nebraska. In 1999, its range expanded into much of North America causing damage from Nebraska to Canada and Mexico. WBC periodically causes kernel damage as severe as 15 bu/ac for one larva/plant. Control for WBC relies on Bt corn hybrids with Vip3A and Cry1F traits and insecticides. There has been a 5.2-fold decrease in efficacy of Cry1F for WBC. Concerns over management tactics may be creating space for conservation biological control to become part of a WBC integrated pest management (IPM) program. Objective 1, used …

Ecology And Integrated Pest Management Of Western Bean Cutworm Striacosta Albicosta (Smith) (Lepidoptera: Noctuidae) In Field Corn, Silvana Vieira De Paula Moraes
Department of Entomology: Dissertations, Theses, and Student Research
Western bean cutworm, Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), is a native pest of dry beans (Phaseolus vulgaris L.) and corn (Zea mays L.), and historically distributed in the western United States. The insect’s recent expansion eastward is documented since 1999. The species is univoltine, the adults typically emerge in the middle of July, lay eggs on corn leaves, and the larvae feed on different corn tissues. In the fourth instar, larvae start colonization of the ear where they feed on kernels. There is a narrow window for management and early detection of the pest in the field is …
Population Genetics Of The Western Bean Cutworm (Striacosta Albicosta Smith) Across The United States, Erica Lindroth
Population Genetics Of The Western Bean Cutworm (Striacosta Albicosta Smith) Across The United States, Erica Lindroth
Department of Entomology: Dissertations, Theses, and Student Research
The western bean cutworm, Striacosta albicosta (Smith), is a secondary pest of maize (Zea mays L.) and dry beans (Phaseolus vulgaris L.) in the western United States. Recently, this insect has undergone a major territory expansion into the eastern US and has become a pest throughout much of the Corn Belt. This study was instigated to examine the population genetics of this pest to facilitate control and resistance management, as well as to shed light on the current habitat expansion. To this end, western bean cutworm individuals were collected from 28 different locations across the traditional and expanded …
