Bactrocera oleae

Synthesis of Haptens and the development of an enzyme-linked immunoassay (ELISA) for the olive fruit fly pheromone, Bactrocera oleae has been reported. 

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. 

The olive fmit fly (Bactrocera oleae) is the major pest of olive trees in Mediterranean countries such as Greece, Israel, Italy and Spain. In 1980 Baker, Francke and their respective coworkers isolated and identified the female-produced sex pheromone of B. oleae as l,7-dioxaspiro[5.5]undecane (116, Figure 4.74), and named it olean.132 Its racemate ( )-116 can readily be synthesized as shown in Figure 4.74, and is pheromonally active.132... 

The Olive fruit fly (Bactrocera oleae) originates most likely from the Mediterranean countries, where infestations have been reported even in BC times. The pest spread further to South Africa, across the Middle East to Pakistan and northern India. Since 1998, also olive plantations in California are threatened (Fig. 8.86). The pheromone of the Olive fruit fly is olean, aspiroketal (1,7-Dioxa-spiro[5.5]undecane).

Another interesting situation is the olive fruit fly (Bactrocera oleae). The female produces the sex pheromones J -olean and S-oleanasdrawninFigure4.10 [19]. The J -olean excites males, and the S-olean excites herself One final example of the amazing variety of ways in which insects use chirality is the...
