“…Drosophila melanogaster is widely used in aging studies (Lints & Soliman, 1988), and, indeed, the advantages of the fruit fly are obvious: short life span, short generation time, small size, inexpensive and easy rearing, and well-known genetics. However, only some behavioral patterns have been investigated in aged flies, namely, various forms of locomotor activity and sexual behavior (see reviews in, respectively, Le Bourg, 1988; Obin, Van der Meer, & Ehrman, 1988). As far as we know, only one work (Le Bourg, 1983a) has been devoted to a simple form of learning—habituation—in aged flies.…”

Young (7 days old), middle-aged (30 days old), and old (50 days old) Drosophila melanogaster males were used in an inhibitory conditioning of the proboscis-extension response. Two reinforcement schedules were applied, constant vs. partial. Partial reinforcement increased the number of trials needed to reach the learning criterion to the same extent in all age groups. Young flies needed fewer trials to reach the criterion than both middle-aged and old flies, which did not differ from each other. Extinction was delayed in the partial reinforcement groups by the same amount in all age groups. The slowest rate of extinction was observed in the old group and the fastest for the middle-aged flies. The results are discussed in connection with hypotheses that consider extinction an index either of behavioral rigidity or of strength of the initial learning.

Evolutionary adaptation and stress: Energy budgets and habitats preferred

Natural populations are normally exposed to substantial environmental stress. The consequences of stress include elevated metabolic costs and additive genetic variability. From the former, preferred habitats should be located in environments corresponding to minimum total energy expenditure. This tendency occurs in the field for behavioral adaptation of Drosophila to variable temperature (and humidity) conditions. Laboratory studies of resource preference in Drosophila suggest a low genetic variability. However, under more stressful field conditions, genetic variability should be higher. Habitat preference studies under stressful conditions therefore need to be emphasized in modeling situations in nature.
