“…Selection for changes in the ratio produced by female pink bollworms was accompanied by a correlated change in male wingfanning response (Collins & Cardi, 1989b). Similarly, the attractiveness of pheromone produced by female khapra beetles (Trogoderma grunarium Everts) was altered in a line selected for reduced male response (Rahalkar et al, 1985). However, in the present study the duration of wing fanning to a 44% ZE blend did not change in the line selected for increased pheromone titre; there appears to be no genetic correlation between these characters.…”

The genetic basis of pheromone titre in the pink bollworm moth, Pectinophora gossypiella (Saunders), was examined through artificial selection for females that produce greater amounts of the sex pheromone [a mixture of (Z,E)and (Z,Z)-7,ll-hexadecadienyl acetates]. Mean (+SD) pheromone titre increased by 91%, from 24.0k8.1 to 45.8k7.9 ng per female, in six generations of selection. No change in component ratio was observed within the selected line. The duration of male wing fanning, measured in a still-air bioassay, did not change in the femaleselected line.

We determined the chirality of ipsdienol in individual male pine engravers,Ips pini (Say), from New York, California, and two localities in British Columbia (BC). Both quantity and chirality of ipsdienol varied significantly between and within populations ofI. pini. Beetles from California and southeastern BC produced primarily (R)-(-)-ipsdienol with mean ratios of (S)-(+) : (R)-(-) of 9 : 91 and 11 : 89, respectively, while beetles from New York produced primarily (S)-(+)-ipsdienol with a mean (S)-(+) : (R)-(-) ratio of 57 : 43. A population from southwestern BC was unlike any other known western population, producing primarily (S)-(+)-ipsdienol with a mean (S)-(+) : (R)-(-) ratio of 66 : 34. In contrast to the unimodal chirality profiles for ipsdienol production in populations from California and southeastern BC, the profiles of the populations from southwestern BC and New York were bimodal, with a common mode at approximately 44 : 56 (S)-(+) : (R)-(-). Bimodality in the profiles of ipsdienol chirality in two populations ofI. pini and remarkably high levels of intrapopulation variation in pheromone chirality in all four populations suggest that evolutionary change in pheromone channels of communication could occur, possibly in response to artificial selection pressures such as mass trapping.
