Response of Sweet Corn Varieties to the Corn Earworm
Author: Richard B. Chalfant
Publisher:
ISBN:
Category : Corn
Languages : en
Pages : 16
Book Description
Fifteen sweet corn varieties were evaluated in a four-year study for resistance to the corn earworm, Heliothis zea (Boddie). Varieties differed significantly in resistance factors, including percent of ears damaged and feeding preference. There was a significant negative correlation (r=0,92) between percent ears damaged and days from planting to tasseling. The most susceptible varieties tasseled before 40 days.

Corn Earworm Resistance Mechanisms in Sweet Corn
Author: Virginia Mae Moore
Publisher:
ISBN:
Category :
Languages : en
Pages : 0
Book Description
This doctoral research examines the efficacy of mechanisms of resistance to the corn earworm ([Helicoverpa zea]) in sweet corn, with a special focus on the application of resistant varieties in organic systems. Corn earworm causes significant damage to sweet corn and its biology and behavior make it difficult to manage for sweet corn growers generally, but especially for organic growers. Plant breeding is one approach that may reduce the damage caused by corn earworm. This work explores possible resistance mechanisms include long husks and maysin content as well as the impacts and management of corn earworm in the context of organic farming systems. [Chapter 1] reviews literature concerning the biology, management, and resistance breeding of corn earworm. [Chapter 2] describes a recurrent selection experiment focused on increasing the husk extension past the ear tip in a sweet corn population and its relation to corn earworm resistance. [Chapter 3] describes a factorial experiment examining the relationship between both husk extension and maysin content and corn earworm resistance. [Chapter 4] describes a survey and a series of interviews with organic sweet corn growers concerning their experiences with and management of corn earworm.

Insect Resistance Management
Author: David W. Onstad
Publisher: Academic Press
ISBN: 0123972337
Category : Science
Languages : en
Pages : 561
Book Description
Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. - Provides insights from the history of insect resistance management (IRM) to the latest science - Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues - Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research - Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions
