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 کاملManaging the Risk of European Corn Borer Resistance to Transgenic Corn: An Assessment of Refuge Recommendations
Industry and scientists have worked to develop a high-dose refuge management plan that can effectively delay European corn borer (ECB) resistance to new genetically modified pesticidal corn. For a high dose, the corn expresses enough pesticide to kill all but the most resistant corn borers. For refuge, producers plant a traditional corn variety that allows susceptible corn borers to thrive and ...
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 کاملQuantitative assessment of biotic mortality factors of the European corn borer (Lepidoptera: Crambidae) in field corn.
Five treatments were used to exclude naturally occurring predators and parasitoids, based on body size and flight ability, to assess their effect on Ostrinia nubilalis (Hübner) populations on corn plaits. Two initial O. nubilalis egg densities (one egg mass and three egg masses per plant) were assigned to each treatment. Egg predation was higher in uncaged treatments than in caged treatments. F...
