European Corn Borer (Lepidoptera: Pyralidae) Larvae~ and Striped Cucumber Beetle (Coleoptera: Chrysomelidae)l

J. Econ. Entomol. ii: 1144-1148 (1984) ABSTRACT Seed oils of many sapindaceous plants contain substantial amounts of cyanolipids. Several of these oils stimulated aggregation of the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the confused flour beetle, Tribolium confusum (Jacquelin duVal). In a pitfall bioassay, they attracted the sawtoothed grain beetle and the rice weevil, Si...

Evaluation of thiamethoxam and imidacloprid as seed treatments to control European corn borer and Indianmeal moth (Lepidoptera: Pyralidae) larvae.

Efficacy of thiamethoxam (Cruiser) and imidacloprid (Gaucho) were evaluated as seed treatments for controlling European corn borer, Ostrinia nubilalis (Hübner) and Indianmeal moth, Plodia interpunctella (Hübner) larvae in stored grain. At approximately 22-26 degrees C, all fifth instar European corn borers died after two or 4 d of exposure to corn treated with 250 and 500 ppm thiamethoxam, resp...

Distribution 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...

High-efficiency Pheromone Trap for the European Corn Borer (Lepidoptera: Pyralidae)

J. Econ.Entomol.79: 1139-1142 (1986) ABSTRACT A Heliothis cone trap captured significantly higher numbers of male European corn borers, Ostrinia nubilalis (Hubner), than a sticky wing trap. Behavioral observations revealed that the difference in number of males captured was related to the proportion of moths approaching the traps that was subsequently captured. Cone traps baited with a 97:3 ble...
