Holometabolous insects pass through a sedentary pupal stage and often choose a location for pupation that is different from the site of larval feeding. We have characterized a difference in pupariation site choice within and between sibling species of Drosophila. We found that, in nature, Drosophila sechellia pupariate within their host fruit, Morinda citrifolia, and that they perform this behavior in laboratory assays. In contrast, in the laboratory, geographically diverse strains of Drosophila simulans vary in their pupariation site preference; D. simulans lines from the ancestral range in southeast Africa pupariate on fruit, or a fruit substitute, whereas populations from Europe or the New World select sites off of fruit. We explored the genetic basis for the evolved preference in puariation site preference by performing quantitative trait locus mapping within and between species. We found that the interspecific difference is controlled largely by loci on chromosomes X and II. In contrast, variation between two strains of D. simulans appears to be highly polygenic, with the majority of phenotypic effects due to loci on chromosome III. These data address the genetic basis of how new traits arise as species diverge and populations disperse.

“…Pupation site preference has been thoroughly investigated in the laboratory [36][37][38] and more rarely in nature [39]. This choice depends on abiotic factors such as temperature [37], darkness [40] or the nature of the substrates [41]. In particular, D. simulans prefers to pupate on rough and humid surfaces while D. hydei prefers dry and smooth surfaces.…”

Animals can be permanently attached to a substrate in terrestrial environments at certain stages of their development. Pupa adhesion has evolved multiple times in insects and is thought to maintain the animal in a place where it is not detectable by predators. Here, we investigate whether pupa adhesion in Drosophila can also protect the animal by preventing potential predators from detaching the pupa. We measured the adhesion of Drosophila species sampled from the same area and found that pupa adhesion varies among species, which can be explained by different glue production strategies. Then, we compared attached and manually detached pupae in both field and laboratory assays to investigate the role of pupa adhesion to prevent predation. First, we found that attached pupae remain onsite 30% more than detached pupae in the field after 3 days, probably because they are less predated. Second, we observed that attached pupae are less efficiently predated by ants in the laboratory: they are not carried back to the ant nest and more ants are needed to consume them onsite. Our results show that pupa adhesion can prevent the animal from being taken away by predators and is crucial for Drosophila fly survival.

“…Drosophila pupation behavior and pupation sites have been thoroughly investigated in the lab (Erezyilmaz and Stern, 2013;Schnebel and Grossfield, 1992;Vandal et al, 2008) and more rarely in nature (Beltramí et al, 2010). Pupation behavior depends on abiotic factors such as temperature (Schnebel and Grossfield, 1992), darkness (Rizki and Davis, 1953) or the nature of the substrates (Godoy-Herrera and Luis, 1998). In particular, D. simulans prefers to pupate on rough and humid surfaces while D. hydei prefers dry and smooth surfaces.…”

Animals can be permanently attached to a substrate for several days, weeks or months in aerial environments at certain stages of their development such as eggs and pupae. Pupa adhesion has evolved multiple times in insects and is thought to maintain the animal in a place where it is not detectable by predators. Here, we investigate whether pupa adhesion in Drosophila could also protect the animal by preventing potential predators from detaching the pupa. We measured the adhesion of Drosophila species originating from the same area and found that pupa adhesion varies among species, which can be explained by different glue production strategies. Then, we compared attached and manually detached pupae in both field and laboratory assays to investigate the role of pupa adhesion to prevent predation. First, we found that attached pupae remain on site 30 % more than detached pupae in the field after three days, probably because they are less predated. Second, we observed that attached pupae are less efficiently predated by ants in the laboratory, because they are not carried back to the ant nest and because more ants are needed to consume them onsite. Our results show that pupa adhesion is a crucial mechanical trait for Drosophila fly survival that can prevent the animal from being taken away by predators.
