Abstract english

Aggregation pheromones of Drosophila immigrans, D. phalerata and D. subokscura were demonstrated by testing attraction of adult flies to hexane extracts of the flies in a windtunnel bioassay. Extracts of adult males of all species attracted conspecific males and females. However. D. suhobscura flies were attracted only when the extract was applied on food. GC-MS analysis identified (Z)-11-octadecenyl acetate (cVA) in the extracts of adult male D. immigrans and D. phalerata. Both species were attracted to synthetic cVA. Male and female D. subobscura produced 5,9-pentacosadiene, 5-pentacosene, 2-methylhexacosene and 5.9-heptacosadiene. while only male D. subobscura produced (Z)-5-tricosene and minor amounts of cVA.
