Flight 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 کاملNutrition of the European Corn Borer, Pyrausta Nubilalis (hbn.)
1. The European corn borer larva has been shown to require a dietary source of one or more unidentified factors contained in corn leaves, grass juice concentrate, and certain other plant materials. The required factor or factors has been termed the corn leaf factor. 2. The corn leaf factor does not appear to be identical with any of the known B vitamins, or with ascorbic acid, sodium nucleate, ...
متن کاملRisk 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 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...
