In pheromone extracts of calling female Chiasma clathrata L. (Lepidoptera: Geometridae), a defoliator pest of alfalfa, (Z,Z,Z)-3,6,9-heptadecatriene and (Z,Z)-6,9-cis-3,4-epoxyheptadecadiene was identified. Chiral gas chromatography using a modified cyclodextrin and synthetic reference samples proved the natural epoxide to show (3R, 4S)-configuration. In field trapping tests, only the pure (3R, 4S)-enantiom er of the epoxide attracted males. The addition of the triene component was synergistic. Males of the sympatric species Tephrina arenacearia Hbn. (Lepidoptera: Geometridae) were caught only in traps with baits containing the (3S, 4R)-enantiomer [together with a previously described minor component, (Z,Z)-3,9-cis- 6,7-epoxyheptadecadiene]. In trapping tests conducted in a different biotope, Abraxas grossulariata L. (Lepidoptera: Geometridae) males were attracted by the (3S, 4R)-enantiomer, whereas the (3R, 4S)-enantiomer attracted a close relative, Abraxas sylvata Scop. (Lepidoptera: Geometridae). The present results suggest that one of the key mechanisms responsible for pheromone specificity among both the two alfalfa geometrids and the two A braxas species in their respective biotops, may be the use of different enantiomers of the same polyenederived epoxide as a sex pheromone component. It is probable that this discrimination mechanism is widespread among moth species utilizing epoxide pheromone components

AbstractThe taxonomic concepts of the Ips species of groups IV and X were tested by controlled breeding, bioassay of sex pheromone specificity, and examination of morphological and karyological details. No changes were made in the status of Ips pini, I. bonanseai, and I. avulsus of group IV. I. interstitialis of group X is removed from synonymy with I. calligraphus, and I. ponderosae, also previously considered a synonym of I. calligraphus, is assigned subspecific rank. Assertions of close phylogenetic relationship of the Eurasian I. duplicatus and I. sexdentatus with groups IV and X, respectively, are rejected.I. pini from widely separated localities were interfertile although egg hatchability was subnormal in some crosses involving F1 from matings of beetles from western and eastern North America. I. pini and I. bonanseai readily mated but less than 3% of the eggs hatched and the larvae died. There was no evidence of breeding incompatibility in crosses of I. c. calligraphus from Florida and California or I. c. ponderosae from New Mexico and South Dakota. However, hatchability differed drastically between reciprocal pairings of the I. calligraphus subspecies, possibly as a result of cytoplasmic incompatibility. All eggs produced in pairings of I. interstitialis with either of the I. calligraphus subspecies failed to hatch.First meiotic metaphase of I. pini, I. bonanseai, and both I. calligraphus subspecies invariably showed the formula 15AA + Xyp. This karyotypic formula also applied to I. avulsus except for a few individuals that had 2 small supernumerary chromosomes. The karyotype of I. interstitialis was not determined. Heteromorphic bivalents and univalents were detected in hybrids of the I. calligraphus subspecies.Cross attractiveness to sex pheromones was demonstrated for I. pini from different regions, for I. pini and I. bonanseai, and for the I. calligraphus subspecies. When samples of attractive frass from eastern and western I. pini males were presented simultaneously, eastern females responded equally to both samples but western females favored western frass by a margin of 2 to 1. Similarly, I. c. calligraphus clearly discriminated in favor of consubspecific pheromone while I. c. ponderosae did not.The locality of several of Eichhoff’s holotypes is noted.
