Abstract.A sequence analysis of the mitochondrial cytochrome oxidase subunit II (COII) gene in Russian and Turkish maizeassociated populations of Ostrinia nubilalis and a Slovenian population of O. nubilalis probably infesting maize revealed little diversity. This lack of diversity may have resulted from bottleneck event(s) when the maize-associated population of O. nubilalis expanded from small population(s) in association with the cultivation of maize in Europe ca. 500 years ago. In the genealogy of COII genes obtained in the present and previous studies, Eurasian samples were substantially differentiated from North American samples.

In New York state, there are three races of European corn borer moths, which are characterized principally by differences in voltinism and the sex pheromone communication system. One race is bivoltine, with females producing and males responding to a 99:1 EIZ isomeric ratio of~1l-14:0Ac's as the sex pheromone. Two races, one univoltine and one bivoltine, produce and respond to a 3:97 E 12 blend of~1l-14 :OAc·s. The races are referred to as BE, UZ, and BZ to denote these differences. Analyses by gas chromatography of field-collected females indicate that there is significant hybridization between the Z and E races when in sympatry, with hybrid females producing a 68:32 ratio of E/Zl1-14:OAc. Gene flow among the races was investigated using differences in triose phosphate isomerase (TPI) allozyme frequencies of moths from sites sampled across the state. The fixed nature of the Tpi-l allele in the BE race and increases in the Tpi-l allele frequencies in UZ populations in sympatry with the BE race support the hypothesis that gene flow following hybridization is unidirectional from BE populations into the Z populations. In addition, the TPI genotypes of the 10 hybrid females analyzed were consistent with hybridization occurring by E males mating with Z females.

“…The species occurs in two strains that use opposite pheromone component ratios. Females of the Z-strain produce 97% Z11-14:OAc and 3% E11-14:OAc whereas E-strain females produce 99% E11-14:OAc and 1% Z11-14:OAc (Anglade et al, 1984;Klun and Robinson, 1971;Klun et al, 1973). Consequently, the strains do not freely interbreed in sympatry (Cardé et al, 1978;Malausa et al, 2005).…”

SUMMARY The European corn borer Ostrinia nubilalis (Hübner) is a model of evolution of sexual communication in insects. Two pheromone strains produce and respond to opposite ratios of the two pheromone components, Z11 and E11-tetradecenylacetate. The Z-strain uses a ratio of 97:3 of Z11:E11 tetradecenylacetate, whereas the E-strain uses a ratio of 1:99. We studied how the difference in male preference correlates with differences in wiring of olfactory input and output neurons in the antennal lobe (AL). Activity-dependent anterograde staining, intracellular recording and immunocytochemistry were used to establish the structure and function of male olfactory receptor neurons (ORNs) and AL projection neurons (PNs). Physiologically characterized neurons were reconstructed using confocal microscopy of α-synapsin stained ALs. The ALs of males and females in both strains had approximately 64 glomeruli. In males the macroglomerular complex (MGC) was morphologically similar in the two strains and consisted of two major compartments, a large, medial compartment folded around a smaller,lateral one. Extensive physiological and morphological analysis revealed that in both strains the major pheromone component-specific ORNs and PNs arborize in the medial MGC glomerulus, whereas those sensitive to the minor pheromone component arborize in the lateral glomerulus. In other words, the two strains have an indistinguishable MGC morphology, but a reversed topology. Apparently,the single-gene-mediated shift that causes a radical change in behavior is located upstream of the antennal lobes, i.e. at the ORN level.
