摘      要：Drosophila buzzatii and *** are sibling cactophilie *** former breeds primarily on prickly pears (genus Opuntia)whereas the latter breeds on columnar cacti of the genera Cereus and Trichocereus,although with certain degree of niche *** examined the interspecific differences in diurnal temporal patterns of adult emergence from puparia and evaluated whether this behavior is affected by rearing in the different cactus hosts available in *** detected important host-dependent genetic variation for this trait differentially affecting the emergence schedule of these *** pattern of emergence time was directly correlated with developmental time and negatively correlated with adult wing size,suggesting that early emergences are at least indirectly correlated with increased *** discussed our results in terms of their putative effects on fitness and the genetic-metabolic pathways that would be presumably affected by host s nutritional-chemical differences.
