In fish reproduction, the best-investigated pheromone system is that of the goldfish [Carassius auratus). Here, sex steroids and prostaglandins play important roles. The female produces two pheromones sequentially a preovulatory primer pheromone and a postovulatory prostaglandin pheromone that act on the male.

A bifunctional sex-aggregation pheromone system may also exist with unidentified Caloglyphus sp. sasagawa, in which the major component, rosefuran (24), acts as a female sex pheromone with a sigmoidal dose-response curve (unpublished data), and /i-phenylelhanol (30), a minor component, functions as an aggregation pheromone. 

An alternative combination of an aggregation-alarm pheromone system is found in L. konoi. This species produces the aggregation pheromone lardolure (44) as a minor component, and the alarm pheromone neral (2) as a major component. If both pheromones are presented simultaneously, aggregation pheromone activity manifests only after the alarm pheromone has dissipated. Furthermore, it seems likely that the mites can regulate the production of each component independently, because the evidence suggests that each is produced at a different site. Therefore, lardolure may be produced essentially continuously, and its function as an attractant is temporarily overridden by the rapid release of the alarm pheromone under adverse circumstances.

The chemical and behavioral aspects of the sex pheromones of several forest defoliating insects of economic importance in eastern Canada are presented, with emphasis on the spruce budworm, Choristoneura fumiferana. Studies conducted over several years in New Brunswick on the use of pheromones as potential control agents, using in particular the air permeation technique to effect mating disruption, are discussed. The identification and the behavioral effects of minor components of the spruce budworm pheromone system are presented and the potential exploitation of their behavioral roles in the mating sequence in terms of control strategies are addressed.

In particular, the importance of chirality in diverse pheromone systems has been reviewed recently (Mori, 1998). For example, olive fruit flies (Bactrocera oleae) emit racemic 2 the males detect the R enantiomer, while females detect the S (Haniotakis et al., 1986). The sex pheromone of the Osaka beetle (Anomala osakana) is 4a, while the closely related Japanese beetle (Popilia japonica) uses 4b (Table 16.1). Interestingly, 4a is a powerful behavioral antagonist in P. japonica (Tumlinson et al., 1977). The hemlock looper, Lambdina fiscellaria, responds only to (5R, 1 S)-5,I I -dimethylheptadecane. The enantiomer or the R/R or S/S diastereomers do not elicit electrophysiological or behavioral responses (Li et al., 1993). Table 16.1 gives an overview of those species where proteins from the pheromone olfactory system have been identified.
