Evolution of moth sex pheromones via ancestral genes
Data is presented supporting the hypothesis that a major shift in the pheromone of an Ostrinia species occurred by activation of a nonfunctional desaturase gene transcript present in the beryllium gland, and the existence of rare males that respond to the new phersomone blend. Expand
A delta 9 desaturase gene with a different substrate specificity is responsible for the cuticular diene hydrocarbon polymorphism in Drosophila melanogaster.
Functional expression of desat1 in CS and Tai is cloned and it is suggested that desat2 might play a control role in the biosynthesis of 5,9 HD hydrocarbons in Tai females and could explain the dienic hydrocarbon polymorphism in D. melanogaster. Expand
Sex pheromone production and perception in European corn borer moths is determined by both autosomal and sex-linked genes.
Investigation of inheritance patterns in pheromonally distinct populations of European corn borers from New York State supports speculation that the Z morph is the ancestral and that the E Morph is the derived European corn borer population. Expand
Purification, identification, concentration and bioactivity of (Z)-7-dodecen-1-yl acetate: sex pheromone of the female Asian elephant, Elephas maximus.
The remarkable convergent evolution of this compound suggests that compounds identified in mammalian exudates that are also present in pheromone blends of insects should be re-evaluated as potential mammalian chemosignals. Expand
Sex pheromone of the european corn borer,Ostrinia nubilalis (Lepidoptera: Pyralidae), in New York
Two pheromone components of the European corn borer, Ostrinia nubilalis (Hübner), from New York are identified and this isomeric blend extracted from the female abdominal tips is very similar to the most attractive synthetic mixture in the field in New York. Expand
Genetic control of voltinism characteristics in European corn borer races assessed with a marker gene
The close correlation of TPI phenotypes and PDD times in these crosses, along with similar results for the maternal and paternal backcrosses of the F1 individuals, indicates that the PDD time is principally controlled by genes on the Z chromosome and that heterozygous males exhibit incomplete or partial dominance of these genes.

Fruit odor discrimination and sympatric host race formation in Rhagoletis
It is shown that historically derived apple- and ancestral hawthorn-infesting host races of the fly use fruit odor as a key olfactory cue to help distinguish between their respective plants. Expand

Data will be presented to support the hypothesis that this process was used in the evolution of the Asian corn borer, Ostrinia furnacalis species and sex-pheromone desaturase genes seem to be evolving under a birth-and-death process. Expand
Three European corn borer populations in New York based on sex pheromones and voltinism
The combinations of voltine biotypes and pheromone strains found in New York support the existence of three European corn borer populations designated bivoltineE, biv HoltineZ, and univoltinZ. Expand
Identification of a New Blend of Apple Volatiles Attractive to the Apple Maggot, Rhagoletis pomonella
Solid-phase microextraction (SPME) and gas chromatography coupled with electroantennographic detection (GC-EAD) were used to identify a new blend of volatiles from apples as the key attractants forExpand
