Genetic variation in the strongly canalized sex pheromone communication system of the European corn borer, Ostrinia nubilalis Hübner (Lepidoptera; Pyralidae).
The major difference in pheromone production between the so-called E and Z strains of the European corn borer Ostrinia nubilalis is controlled by two alleles at a single autosomal locus. E-strain females produce an (E)-11-tetradecenyl acetate pheromone with 1-3% of the Z isomer, whereas Z-strain females produce the opposite blend. In laboratory-reared insects we found that F1 females produced, ...
متن کاملOptimizing Trichogramma ostriniae (Hymenoptera: Trichogrammatidae) releases to control European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae) in bell pepper
The effective dispersal ability of the egg parasitoid Trichogramma ostriniae Pang and Chen was assessed in potato fields on the Eastern Shore of Virginia in spring 2005 and 2006. Approximately 0.5 million T. ostriniae were released from a central release point in separate potato fields. Dispersal was monitored using yellow sticky card traps and European corn borer, Ostrinia nubilalis Hübner, eg...

متن کاملNo linkage between genes controlling female pheromone production and male pheromone response in the European corn borer, Ostrinia nubilalis Hübner (Lepidoptera; Pyralidae).
The E and Z pheromonal strains of the European corn borer, Ostrinia nubilalis, are characterized by female production of and male preference for opposite blends of (E)-11-and (Z)-11-tetradecenyl acetate. It is known that the pheromone production is controlled by an autosomal gene and that the males' behavior is determined by a sex-linked gene. A third gene, autosomally inherited, has been shown...
