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 کاملFlight behaviour of European corn borer infected with Nosema pyrausta
The European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae), is a major pest of corn, Zea mays L., in North America, Europe and Asia. Before the introduction of transgenic Bt corn targeting lepidopteran pests, the European corn borer was responsible for over $1 billion in damage and control measures annually in the U.S. alone (Mason et al. 1996). Management of this insect historically ...
متن کاملCombined Impacts of Western Corn Rootworm Larval Feeding, European Corn Borer and Giant Foxtail on Field Corn
Corn rootworm (CRW) beetles exhibit a univoltine life cycle. Feral adults deposit their eggs into the soil of cornfields during July and August where they undergo diapause and overwinter. The following spring eggs hatch beginning in late May and continuing on into the middle part of June. Larvae of the new generation feed on developing corn roots. After reaching the third instar larvae pupate i...
