| genetic analysis of drosophila sechellia specialization: oviposition behavior toward the major aliphatic acids of its host plant. | oviposition behavior of the four species in the drosophila melanogaster complex (d. melanogaster, d. simulans, d. mauritiana, d. sechellia) was investigated versus natural morinda fruit (the normal resource of d. sechellia) and the two major aliphatic acids of this fruit (hexanoic acid, c6, and octanoic acid, c8). two different experimental techniques were compared. when control and experimental food were set on the same egg laying plate, three species (d. sechellia, d. mauritiana, d. melanogast ... | 1998 | 9926614 |
