    Notes: Abstract Preadult seclusion imposed upon members of theDrosophila paulistorum complex of intersterile semispecies significantly decreased sexual isolation between adults of the semispecies. While seclusion at any developmental stage had this effect, there were quantitative variations correlated with the stage at which seclusion had been initiated: the earlier the stage at which seclusion began, the more frequent were the heterogamic matings. All the stages of development seemed to contribute to final adult sexual behavior, with no single stage emerging as the most important experiential phase. Seclusion also significantly affected intrasemispecific matings, in that flies were more likely to mate with partners having similar experiences.

    Notes: Abstract We present results deriving from the inception of an investigation (involving 4,000 scored matings) into the development of discriminatory behavior inDrosophila paulistorum. We examined two complementary situations for their effects on mating behavior: physical isolation (seclusion) beginning at each of six developmental stages and exposure to heterosemispecifics during all preadult stages (mixed culturing). Preadult seclusion at certain stages decreased sexual isolation between three of four semispecific pairs. Seclusion effect, or lack thereof, varied with semispecies and with the stage at which seclusion was imposed: the earlier the stage at which seclusion was initiated, the more drastic the effect. In contrast, mixed culturing increased sexual isolation between the one pair of semispecies that was tested.

    Developmental isolation and subsequent adult behavior ofDrosophila paulistorum. III. Alternative rearing (1996)

    Notes: Abstract We have been utilizing membres of theDrosophila paulistorum complex of semispecies to study the development of adult discriminatory behavior. In this study, three rearing methods were used to examine the effects of previous exposure to heterosemispecifics on reproductive isolation among the various semispecies. Experimental flies were exposed to heterosemispecifics by one of three methods: exposure to airborne heterosemispecific stimuli from egg through sexual maturity, physical contact with heterosemispecifics only during the postimaginal period, and mixed culturing (total physical contact with heterosemispecific individuals during each of five preimaginal stages). Effects of the first treatment varied with semispecies. The second treatment had no significant effect on mating behavior. The third treatment of mixed culturing reinforced sexual isolation.

    Developmental Isolation and Subsequent Adult Behavior of Drosophila paulistorum.IV. Courtship (1998)

    Notes: Abstract Early social experiences play important roles in adult Drosophila paulistorummate selection. Differences in courtship between control males and wholly socially isolated males were observed in chambers. Socially isolated males displayed more courtship toward virgin females than did controls. Socially isolated males were more successful in competing for mates. Yet socially isolated males from all six semispecies also displayed notable frequencies of homosexual behavior.
