    Notes: Abstract Oviposition behavior of the four species in the Drosophila melanogastercomplex (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. melanogaster) exhibited a significant preference for morinda; with aliphatic acids, only D. sechelliamanifested a preference. With separate oviposition sites, a preference was found in D. sechelliafor morinda and acids, and a general avoidance behavior in the three other species. Genetic analysis of the behavioral response toward C6 and C8 was done with the two plates technique on D. sechellia, D. simulans, F1 hybrids and backcrosses. Significant behavioral differences were observed with major effects due to genotype, concentration and their interaction. Hybrid behaviors were intermediate between those of their parents. In several cases, a qualitative reversal from preference to avoidance was observed with increasing concentration. In F1 flies, a dominance reversal was observed with increasing C8 concentration. Different reaction thresholds in different receptors might explain such observations.

    Genetics of a nonoptimal behavior: Oviposition preference ofDrosophila mauritiana for a toxic resource (1994)

    Notes: Abstract Among three sibling species of theD. melanogaster subgroup, two are generalists (D. simulans andD. mauritiana), while the third,D. sechellia, specializes on a single toxic resource, the fruit ofMorinda citrifolia. D. sechellia, resistant to the toxics, prefers to oviposit on morinda;D. simulans, which is very sensitive, is strongly repelled.D. mauritiana exhibits an aberrant behavior since it prefers to lay its eggs on morinda, where its embryos are killed. Oviposition behavior, studied in parental species, F1 hybrids, and backcrosses, was mostly an additive genetical trait. Further investigations were made withD. mauritiana andD. simulans carrying recessive markers. The X and second chromosomes had no effect, while a clear effect was found for chromosome 3. Since the toxicity of morinda is due to middle-length fatty acids, the behavior of the three species toward various acids was investigated. We found thatD. sechellia exhibited a general oviposition preference for acids, whileD. simulans was repelled by acids with at least four carbons. SurprisinglyD. mauritiana exhibited behavior quite similar to that ofD. simulans. Preference for morinda inD. sechellia andD. mauritiana could be mediated by different chemicals.

    Relation between the genetic variability of digging behavior ofDrosophila larvae and their susceptibility to a parasitic wasp (1985)

    Notes: Abstract TwoDrosophila strains were compared with respect to the behavior of their larvae on food substrate: a wild-type strain (D) from the West Indies exhibited digging behavior, while a laboratory strain (S), bearing theebony mutation, remained on the surface. Chromosome transfers showed this difference to be due mainly to autosomes. There was a significant difference between the two strains in the proportions of larvae parasitized by a cynipid wasp. This was not due to theebony mutation or to other traits such as larval size, cuticle thickness, and speed of development. Chromosome transfers demonstrated a significant role of the three major chromosomes in the susceptibility to the parasite. A clear parallelism was found between the susceptibility to parasitization and the proportion of surface larvae. The depth of concealment of the larvae in the food matter appears to be a favorable behavioral strategy for escaping parasite attacks. The possible adaptive significance of genetic variations in larval behavior is discussed.
