AbstractEuropean corn borer males have hair pencils located ventrally on the 8th sternite and these are extruded when a male approaches a calling female. The fact that (i) antennectomized females mated significantly less than both intact controls and individuals subjected to other forms of surgery, and (ii) males with hair pencils removed had a significantly lower mating success than control males, suggests that a male pheromone is involved in the mating system of the European corn borer.

The European corn borer moth, (ECB), Ostrinia nubilalis (Lepidoptera: Crambidae, Pyraustinae) is one of the most destructive pests of maize worldwide. ECB has two pheromone-strains, separated by specific ratios of isomers of E- and Z11-tetradecenyl acetates (E11- and Z11-14Ac), but appearing morphologically identical. Accordingly, E- and Z-ECB pheromone traps are available for the respective populations for practical monitoring of the flight, however, traps for Z-strain are unreliable for practical usage in some parts of Central-Europe. E- and Z-ECB populations occur in sympatry in some areas, while in allelopatry in other areas. Determining the strains before the flight of adults, when difference in the composition of their respective pheromones is manifested, would be of practical interest for early warning. In addition to the known fatty-acyl-reductase (FAR) marker, further markers would allow more comprehensive studies. We screened the following common markers for mitochondrial and nuclear DNA regions: partial cytochrome c oxidase I (COI), cytochrome B (CytB), the second spacer of the internal transcribed spacer (ITS2), Elongation factor 1a (EF1a) and actin gene (Act). In addition, a marker of the Δ11-desaturase gene (11desat), linked to biosynthesis of female-produced sex pheromone, was also included, because we reported earlier a differential expression for this site. Three Z-ECB populations locating at distant sites within Hungary, an area where only Z-strain occurs, and an E-ECB population in Slovenia, known as the closest-occurring E-strain, were included into the study. Separate laboratory colonies were established from each population, and F1 generations were sampled to verify the identity of pheromone strains, by analysing the composition of sex pheromone by gas chromatography linked to an electroantennographic detector (GC-EAD). Molecular studies were conducted using specimens taken from the F2 generations. Results of genetic studies showed that there were no differences between the Z and E populations for the common markers. In contrast to this, several nucleic acid changes (11 nt in 4 positions) were found between the three Z-populations (Hungary) and the E-population (Slovenia) in the desaturase marker. Further study is required to reveal whether the differences found in this study are consistent across E-populations, thus making these markers suitable for diagnostic purposes.

AbstractThe sex pheromone components of European corn borer, Ostrinia nubilalis (Hbn.), from southern Alberta were identified in washes and extracts of abdomen tips from calling female moths. This is a Z strain population as (Z)-11- and (E)-11-tetradecenyl acetates were isolated in a ratio 100:2.4, and a corresponding synthetic blend in a ratio of 100:3 attracted males in the field. Dodecyl alcohol, tetradecyl alcohol and acetate, and (Z)-11-tetradecenol were also identified, but none of these components nor other "pheromone-like" mono-unsaturated C10 to C16 acetates had any effect on increasing the trap catches of male moths under field conditions. However, the addition of (Z)-9-dodecenyl acetate or (Z)-9-tetradecenyl acetate to the synthetic pheromone blend significantly reduced the capture of male moths, even though these compounds were not detectable in the female extracts. Pheromone blends used for monitoring the Z strain of the European corn borer must be essentially free, ca.< 0.1%, of these acetates. A commercially available, sticky-surface, delta-type trap was the most satisfactory of several tested for capturing moths under prairie conditions.
