    Notes: Abstract Analysis of ovipositor washings from virgin femaleCnaphalocrocis medinalis Guenée (Lepidoptera: Pyralidae) of Indian origin by linked gas chromatography and electroantennography indicated the presence of three electrophysiologically-active compounds. These were identified on the basis of their gas chromatographic retention times and mass spectra as (Z)-11-hexadecenyl acetate, (Z)-13-octadecenyl acetate and (Z)-13-octadecen-1-ol with (Z)-13-octadecenyl acetate present in amounts of between 0.25 and 1.5 ng per ovipositor and the other two components at less than 10% of this. Trace quantities of octadecyl acetate were identified by mass spectrometry but no electroantennographic responses were observed to this compound. Field trials conducted with a range of blends of the three electrophysiologically-active compounds showed that blends containing between 5% and 30% (Z)-11-hexadecenyl acetate in (Z)-13-octadecenyl acetate dispensed from either white rubber septa or polythene vials were more attractive to male moths than a virgin female moth. Addition of (Z)-13-octadecen-1-ol reduced attractiveness to male moths in the blends and concentrations tested.

    Components of the sex pheromone of the female sugar cane borer,Chilo sacchariphagus (Bojer) (Lepidoptera: Pyralidae) (1980)

    Notes: Abstract The female sex pheromone of the sugar cane borer,Chilo sacchariphagus, has been shown to contain the two structurally related compounds, (Z)-13-octadecenyl acetate (I) and (Z)-13-octadecen-1-ol (II). These components were detected in female abdominal tip extracts by gas-liquid chromatography (GLC) combined with electroantennography (EAG), and were identified by their GLC behavior, microozonolysis, and interconversion, and by comparison of natural and synthetic material. Field tests in Mauritius showed that traps baited with components I and II combined in ratios from 1∶1 to 9∶1 caught maleC. sacchariphagus moths, and that the 7∶1 ratio was comparable in performance with a virgin female moth. Neither component presented separately in traps caught significant numbers of moths.
