“…The ‘tunneling effort’ put by the selected and control populations in digging was measured as the time taken for 30 cephalopharyngeal (mouth hook) retractions [ 40 , 41 ] in tunneling larvae (completely burrowed but still digging), in a separate assay. Two assay plates per population were set-up and six days later the plates were closely examined, eight tunneling larvae per plate were haphazardly chosen and their scleratic retraction-rate within the tunnel was determined under a dimly lit stereo-microscope (larvae abandon tunneling under bright light).…”

Structures built by animals are a widespread and ecologically important ‘extended phenotype’. While its taxonomic diversity has been well described, factors affecting short-term evolution of building behavior within a species have received little experimental attention. Here we describe how, given the opportunity, wandering Drosophila melanogaster larvae often build long tunnels in agar substrates and embed their pupae within them. These embedded larvae are characterized by a longer egg-to-pupariation developmental time than larvae that pupate on the surface. Assuming that such building behaviors are likely to be energetically costly and/or time consuming, we hypothesized that they should evolve to be less pronounced under resource or time limitation. In accord with this prediction, larvae from populations evolved for 160 generations under a regime that combines larval malnutrition with limited developmental time dug shorter tunnels than larvae from control unselected populations. However, the proportion of larvae that embedded before pupation did not differ between the malnutrition-adapted and control populations, suggesting that tunnel length and likelihood of embedding before pupation are controlled by different genetic loci. The behaviors exhibited by wandering larvae of Drosophila melanogaster prior to pupation offer a model system to study evolution of animal building behaviors because the tunneling and embedding phenotypes are simple, facultative and highly variable.

“…Traditionally, cephalopharyngeal retractions were used to quantify feeding rate [20], [21], but the absence of correlation between mouth-hook movement and amount of food ingested [22] questions the reliability of this method. We thus use a newer dye-based method [22] instead.…”

Adaptation to Abundant Low Quality Food Improves the Ability to Compete for Limited Rich Food in Drosophila melanogaster

The rate of food consumption is a major factor affecting success in scramble competition for a limited amount of easy-to-find food. Accordingly, several studies report positive genetic correlations between larval competitive ability and feeding rate in Drosophila; both become enhanced in populations evolving under larval crowding. Here, we report the experimental evolution of enhanced competitive ability in populations of D. melanogaster previously maintained for 84 generations at low density on an extremely poor larval food. In contrast to previous studies, greater competitive ability was not associated with the evolution of higher feeding rate; if anything, the correlation between the two traits across lines tended to be negative. Thus, enhanced competitive ability may be favored by nutritional stress even when competition is not intense, and competitive ability may be decoupled from the rate of food consumption.

“…Several studies (Evans, 1980; Walker, 1984) have shown that neurotransmission in the insect is not dissimilar to that found in vertebrates. Not only does one find the same neurotransmitters and often the same breakdown pathways, but correlations can also be established between behavior and neurotransmitter (for example in Drosophila , see Fowler, Goodnight, & Labrie, 1972; Kamyshev, Smirnova, Savvateeva, & Medvedeva, & Ponomarenko, 1983; Sewell, Hunt, Burnet, 1975; Tully, 1987; Tunnicliff, Rick, & Connolly, 1969).…”

In insects the level of serotonin can be modified through the alimentary tract. Drosophila fed on chemically defined media to which has been added a synthesis inhibitor or an immediate precursor of this neurotransmitter have their serotonin level decreased or increased, respectively. (A 4- to 5-day treatment is optimal). Such treated flies, if tested in a procedure of Pavlovian conditioning, have different learning performances. With the same duration of starvation, nearly the same threshold for sucrose solutions, but different amounts of serotonin, the flies (blindly trained) showed conditioned inhibition of the tarsal (or proboscis-extension) reflex according to the amount of serotonin. The highest level of this biogenic amine gave the best performance.
