Risk and the Value of Additional Insecticide Applications for European Corn Borer Control in Processing Sweet Corn
This analysis uses data from field evaluations of pyrethroid insecticides to estimate the uncertainty (risk) and expected value of additional insecticide applications and IPM to control European corn borer larvae in processing sweet corn. Preliminary empirical results indicate that IPM can increase expected returns around $5-$9/ac and reduce the risk (variability) of net returns.
متن کاملIntegrating biological and chemical controls in decision making: European corn borer (Lepidoptera: Crambidae) control in sweet corn as an example.
As growers switch to transgenic crops and selective insecticides that are less toxic to natural enemies, natural enemies can become more important in agricultural pest management. Current decision-making guides are generally based on pest abundance and do not address pest and natural enemy toxicity differences among insecticides or the impact of natural enemies on pest survival. A refined appro...
متن کاملDistribution of European Corn Borer (Lepidoptera: Pyralidae) Egg Masses and Larvae on Sweet Corn in New York
Environ. Entomol. 15: 501-506 (1986) ABSTRACT Studies were conducted in commercial sweet corn fields in upstate New York to collect information for developing a sampling protocol for egg masses and larvae of European corn borer (ECB), Ostrinia nubilalis (Hubner). Information was collected on 1) aggregation of populations in portions of the field (e.g., aggregation along borders), 2) distributio...
متن کاملInheritance of Cry1F resistance in laboratory-selected European corn borer and its survival on transgenic corn expressing the Cry1F toxin.
A major assumption of the high-dose/refuge strategy proposed for insect resistance management strategies for transgenic crop plants that express toxins from Bacillus thuringiensis is that resistance traits that evolve in pest species will be recessive. The inheritance of Cry1F resistance and larval survival on commercially available Cry1F corn hybrids were determined in a laboratory-selected st...
متن کاملUnderstanding successful resistance management: the European corn borer and Bt corn in the United States.
The European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae) has been a major pest of corn and other crops in North America since its accidental introduction nearly a hundred years ago. Wide adoption of transgenic corn hybrids that express toxins from Bacillus thuringiensis, referred to as Bt corn, has suppressed corn borer populations and reduced the pest status of this insect i...
