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, ...

European corn borer, Ostrinia nubilalis (Hübner), is a major pest of processing snap bean because larvae are contaminants in pods. The incidence of O. nubilalis-contaminated beans has become uncommon in New York, possibly because widespread adoption of Bt field corn has suppressed populations. Snap bean fields located where Bt corn has been intensively grown in space and time may be at lower ri...
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...
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.
