    Intensification and prolongation of host searching inLeptopilina heterotoma (Thomson) (Hymenoptera: Eucoilidae) through a kairomone produced byDrosophila melanogaster (1985)
    Springer

    Notes: Abstract A chemical cue (kairomone) of the host, larvae ofDrosophila, was found to influence patch-time allocation of the parasiteLeptopilina heterotoma. This kairomone is soluble in water and chloroform. The kairomone was purified using thin-layer chromatography. The concentration of the kairomone increases with an increasing number of hosts. The parasites may use presence and concentration of the kairomone as cues to determine patch-time allocation.

    Compared behavioral responses of maleDrosophila melanogaster (Canton S) to natural and synthetic aphrodisiacs (1985)
    Springer
    Journal of chemical ecology 11 (1985), S. 1617-1629 
    Details
    ISSN: 1573-1561
    Keywords: Drosophila melanogaster ; Diptera ; Drosophilidae ; aphrodisiac pheromone ; recognition pattern ; cuticular hydrocarbons ; heptacosadienes ; mass spectrometry
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Cuticular aphrodisiacs fromD. melanogaster females were further characterized and the male response specificity towards such natural and synthetic unsaturated hydrocarbons was investigated. The behavioral activity seems to be correlated with some chain-length requirement and double-bond position; at least one double bond in position 7 seems necessary. This position is more abundant among natural monoenes, and among dienes which also bear a second double bond in position 11, whatever the chain length. Bioassays of the synthetic (Z,Z)-7,11-heptacosadiene yielded a dose-response curve close to that of the natural mixture of heptacosadienes in which the 7–11 isomer is predominant. This female specific 7,11 heptacosadiene appears to be the most potent aphrodisiac for males of the species. Its threshold is lower than that of both 7,11-nonacosadiene and 7-pentacosene which might also play a role in sex and species recognition.

    Temperature-dependent responses to a developmental gradient in theDrosophila wing (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1346-1347 
    Details
    ISSN: 1420-9071
    Keywords: Positional information ; temperature effects ; gradients ; campaniform sensillae ; wing veins ; Drosophila melanogaster
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The mutant hairy (h) increases the number of sensillae on theDrosophila wing. This allows us to quantify a gradient that determines the type of sense organ that forms along the third long vein. Temperature significantly shifts the positional responses to this underlying gradient.

    Acetaldehyde oxidation inDrosophila null-mutants for alcohol dehydrogenase (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 946-948 
    Details
    ISSN: 1420-9071
    Keywords: Acetaldehyde oxydation ; alcohol dehydrogenase ; aldehyde dehydrogenase ; Drosophila melanogaster ; Drosophila simulans ; ethanol catabolism ; null-mutants for alcohol dehydrogenase
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Aldehyde dehydrogenase (ALDH) activity is demonstrated in four strains ofD. melanogaster lacking active alcohol dehydrogenase (ADH-null mutants). In the four strains, ALDH activities are similar to those found in a wild strain. It is concluded that ADH-null flies are able to detoxify acetaldehyde. This finding is discussed in relation with the dual function of ADH proposed recently.

    Structural analysis of glycerol-3-phosphate dehydrogenase from severalDrosophila species (1985)
    Springer
    Biochemical genetics 23 (1985), S. 801-814 
    Details
    ISSN: 1573-4927
    Keywords: Drosophila melanogaster ; D. hydei ; D. immigrans ; D. mercatorum ; glycerol-3-phosphate dehydrogenase ; peptide mapping ; amino acid sequencing

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract This report describes preliminary protein structural studies of glycerol-3-phosphate dehydrogenase (α-GPDH) fromDrosophila spp. and an important innovative feature of our enzyme purification protocol. The scheme involves the coupling of substrate (α-glycerophosphate) elution from CM-Sephadex and cofactor (NADH) elution from Affi-Gel blue resin. Using this method a 32.7% yield and a 111-fold purification were obtained from aD. melanogaster line carrying the α-Gpdh S allele at the α-Gpdh locus. The product obtained from 0 to 3-day-old adult flies was electrophoretically homogeneous and consisted mainly of the adult α-GPDH-1 isozyme. The method was used to obtain α-GPDH protein fromD. melanogaster (two lines),D. hydei, D. immigrans, andD. mercatorum. Peptide mapping revealed structural differences among the enzymes from the different species, and amino acid sequencing showed many similarities betweenD. melanogaster α-GPDH and the rabbit muscle enzyme.

    Relation between the genetic variability of digging behavior ofDrosophila larvae and their susceptibility to a parasitic wasp (1985)
    Springer
    Behavior genetics 15 (1985), S. 143-154 
    Details
    ISSN: 1573-3297
    Keywords: Drosophila melanogaster ; digging behavior ; larval depth concealment ; parasitic success
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    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.

    cis-Vaccenyl acetate as an aggregation pheromone inDrosophila melanogaster (1985)
    Springer
    Journal of chemical ecology 11 (1985), S. 1747-1756 
    Details
    ISSN: 1573-1561
    Keywords: Diptera ; Drosophilidae ; Drosophila melanogaster ; pheromone ; (Z)-11-octadecenyl acetate ; cis-vaccenyl acetate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Pentane extracts of matureDrosophila melanogaster males substantially increased the attractiveness of food odors to both males and females in a wind-tunnel olfactometer. Extracts of females caused no such increase. An active component of the extract was isolated and identified as (Z)-11-octadecenyl acetate (cis-vaccenyl acetate, cVA), and synthetic cVA was active in bioassay. Hydrolysis of the ester linkage or movement of the double bond to the 9 position destroyed the activity. Mature virgin males released cVA into their feeding vials, and amounts of synthetic CVA equal to that released per male caused significant bioassay responses. Females, which were known to receive cVA from males during copulation, were found to emit relatively large amounts of the ester into their feeding vials within 6 hr after mating. cVA had been demonstrated previously to be a close-range pheromone inD. melanogaster, discouraging males from courting other males or recently mated females; it now appears to have a longer-range function as well.
