Abstract:We investigate the thermoregulatory behaviors of larvae of four species of Drosophila (D. melanogaster, D. subobscura, D. pseudoobscura, and D. mojavensis), a thermotolerant strain of Drosophila melanogaster (T strain) known to differ in thermal biology, and two mutant stocks of D. melanogaster that have (as adults) defective thermoregulatory behavior. We describe and evaluate new techniques to measure two indices of maximum voluntary temperature of insect larvae. Both measures were highly repeatable within lines (species, strains, or mutants). One measure (temperature at which larvae stood upright) differed among lines consistent with expectations based on adult thermal ecology, suggesting that this measure will be useful measures of thermoregulatory set-points of larvae. The second measure (temperature of emergence from media) is less discriminatory.
