    Notes: Abstract Females ofDrosophila melanogaster were given a choice of oviposition site either on the surface of the medium or on the surface of paper positioned vertically on the medium. A significant difference was seen in the proportion of eggs deposited on the paper among wild strains of different geographic origins. Bidirectional selection for oviposition on these two sites was effective. These selected lines were examined under various conditions to determine the factors involved in this site selection for oviposition. The lines that chose medium laid eggs only on substrates into which egges could be inserted. The lines preferring paper showed no strict requirement for burying their eggs. Tarsal sensillae were involved in site discrimination.

    Relative male age, fertility, and competitive mating success inDrosophila melanogaster (1980)
    Springer
    Behavior genetics 10 (1980), S. 163-170

    Notes: Abstract Female choice experiments were used to investigate the effect of relative male age on mating success inD. melanogaster. Experiments were conducted with a Canton-S (CS) strain, in which two virgin males of different ages (2, 4, or 8 days old) were offered to virgin females. Older males were found to be more successful under competitive conditions. In another group of experiments, vermilion (v) males of different ages competed with CS males of different ages. The competitive success ofv males was found to increase with their relative age. Male fertility at 2, 4, and 8 days of age was documented for both male genotypes mated with CS females. CS males fathered more offspring per copulation thanv males, and the fertility of all males was found to increase with age. Discussion focuses on the changes in male mating success and fertility with age and genotype.

    Notes: Abstract NormalDrosophila melanogaster males rapidly react to changes in the mobility of mutantshibire ts females by performing less courtship when the females are paralyzed and by courting movingshibire ts females vigorously. Mutantoptomotor-blind males, which are unable to respond to certain horizontally moving patterns, sustain abnormally short courtship bouts when tested with normal females, almost never perform orientation, one of the courtship behaviors, and require more time to initiate copulation than normal males. These results suggest that males must perceive female movement to perform normal courtship and copulation. Normal females become stationary before copulation occurs. Normal males mate quickly in response to this change in female behavior, while blind males require more time to effect copulation, prolonging the time that the female remains stationary. Mutantsmellblind females, which do not respond to certain odors, continue to move during the time that they are courted by normal or blind males and also require more time to copulate, suggesting that females may stop moving before mating in response to olfactory cues.

    Topics: Biology , Psychology
    Notes: Abstract Ten wild-type strains ofDrosophila melanogaster were used to compare performance in two different discriminative avoidance tasks, one involving odor as a discriminative stimulus and shock as the aversive stimulus and the other involving colored lights as the discriminative stimulus and vigorous shaking as the aversive stimulus. Significant strain differences were established for performance on both tasks. No significant correlation, however, was observed between performances on the two tasks; this suggests independent genetic control.

    Notes: Abstract A laboratory study is presented which shows that larval foraging behavior in the sibling speciesDrosophila melanogaster andD. simulans can respond rapidly (in six generations) to unidirectional selection. An apparatus was designed which selected for larvae which moved from nonnutritive agar medium to plugs of nutritive medium and remained feeding there. Larvae of the selected lines showed a correlated decrease in foraging path length which mirrored thesitter larval forager behavior type previously defined by Sokolowski [(1980).Behav. Genet. 10:291–302]. This supported the hypothesis that sitter larvae moved toward, and remained feeding on, a food source when they were not already utilizing one, whereasrover larvae foraged from food patch to food patch.

    Elucidating the behavioral phenotype ofDrosophila melanogaster larvae: Correlations between larval foraging strategies and pupation height (1983)

    Notes: Abstract Larvae which demonstrated long trails covering a large area while feeding (rover foragers) pupated significantly higher than those covering a relatively small area and exhibiting short paths (sitter foragers). Pupation height and density of larvae per vial were positively correlated. Under the condition of equal larval density per vial,rovers were found to pupate significantly higher thansitter larval foragers. The effect of three light regimes (constant light, constant darkness, and 12 h light followed by 12 h dark) indicated a more complex relationship between pupation height and larval foraging behavior.

    Notes: Abstract Alcohol preference by adults (1–2 days old) of sympatric populations ofDrosophila melanogaster andD. simulans were studied in a T-shaped glass maze. Concentrations for ethanol, methanol, propanol, and hexanol alcohols (group I) were 10, 25, 35, and 50%; for iso-propanol, butanol, and octanol alcohols (group II), they were 1.5, 2.5, 3.5, and 10%.D. simulans preferred the four alcohols in group I, more thanD. melanogaster. While moreD. melanogaster thanD. simulans preferred iso-propanol, moreD. simulans thanD. melanogaster preferred butanol. The two species had a similar preference for octanol. Regardless of the position of alcohol in the maze,D. melanogaster preferred to turn right in the presence of all alcohols, whileD. simulans preferred to turn right in the presence of group I alcohols only. At 10% concentration, males of both species preferred to turn right and females preferred to turn left. More females than males ofD. simulans preferred group II alcohols. There was no significant difference among concentrations for all alcohols in group I forD. melanogaster. Highly significant differences among concentrations were detected for group I alcohols forD. simulans and group II alcohols for both species.D. simulans was more dependent on ethanol concentration thanD. melanogaster. There was also an alcohol by concentration interaction forD. simulans group I andD. melanogaster group II. At the common concentration (10%) there was no difference between the two species in their preference for any alcohol, with the following ranking order in attractiveness: methanol〉ethanol〉propanol 〉hexanol〉octanol〉butanol〉iso-propanol. There was a negative correlation between some physical properties of alcohols and their attractiveness. In general, the results are consistent with the “threshold response model.”

    Larval responses to environmental ethanol inDrosophila melanogaster: Variation within and among populations (1980)

    Notes: Abstract There is a latitudinal cline in attraction to ethanol of newly hatchedD. melanogaster larvae; attraction decreases as one moves from the temperate regions to the Australian tropics. Tropical populations manifest high levels of heterogeneity compared with temperate regions, making tropical populations less dependent on ethanol. Since ethanol is a resource forD. melanogaster, an approach to the genetics of resource utilization in natural populations via behavior genetics of larval ethanol responses is feasible, using isofemale strains as experimental material.

    Notes: Abstract In eightDrosophila melanogaster stocks, males which are only a few hours old stimulate courtship which is qualitatively and, in many of the stocks, quantitatively indistinguishable from the courtship elicited by virgin females. Although the sex appeal of young males and the extent to which it declines as the males become sexually mature vary somewhat from stock to stock, homosexual courtship appears to be characteristic of the species.

    Genetic analysis of the circadian oviposition rhythm inDrosophila melanogaster: Effects of drift in laboratory strains (1984)

    Notes: Abstract Under photoperiodic conditions, flies recently collected in nature exhibit, at the beginning of the scotophase, an oviposition peak which has a higher amplitude in Afrotropical than in European temperate populations. Several old laboratory strains failed, however, to show this peak. In each cross between genetically different strains, the oviposition curves of F1 and F2 were usually close to the midparent curve. Ten isofemale lines from an Afrotropical populations were submitted to inbreeding and drift. After 100 generations, two of the four surviving lines had retained the high peak typical of the origin population while the two others had lost it. Chromosome substitutions between these lines demonstrated a polygenic inheritance with a significant effect of the three major chromosomes. Presumably, the variations of amplitude of the oviposition peak were not caused by a modification of the ovarian activity but by a behavioral change toward the external signals of the environment.
