| Outline of Final Research Achievements |
Larvae of cossid moth, Cossus insularis, bore into the fruit trees such as an apples or Japanese pears, form an aggregation and feed the woods. Because chemical(s) may be involved in the formation of a group, we tried to isolate active components releasing aggregation from the volatiles emitted from the larvae.
We collected volatiles from larvae on an absorbent by headspace sampling. Crude extracts were fractionated by column-chromatography and each fraction was behaviorally assayed and active fractions were analyzed by gas chromatography-mass spectrometry. The results indicate that active components may be polar compounds that attract other individuals. There may be a different component other than the attractive component that arrests the larva to maintain an aggregation.
