“…We used a Mann-Whitney U test (Sokal and Rohlf 1995) to compare the mean distance between nearest neighbor D. simulans-D. simulans, and D. buzzatii-D. buzzatii pupae versus mean distance between D. simulans-D. buzzatii and D. buzzatii-D. simulans pupae. We also examined homogeneity for replicates within larval responses to odors of other larvae, and larval reactions to acidity/alkalinity using a variance analysis between replicates within a recording time.…”

We investigated pupa distributions of D. simulans, D. buzzatii, D. melanogaster, D. immigrans and D. hydei on a number of natural breeding sites. Pupae of all five species showed aggregated distributions, which prompted us to examine these aggregations in a more detail for two species that commonly co-occur in breeding sites, D. simulans and D. buzzatii. Wefound that pupae of both species tend to be aggregated in conspecific clusters. Subsequent experiments revealed that both species are attracted to the odors of other larvae, though only D. buzzatii differentiated between conspecifics and heterospecifics (they preferred conspecific). Furthermore, third instar larvae of both species preferred more alkaline substrates. Altogether, our results demonstrate that Drosophila species form conspecific pupa aggregations in natural breeding sites, and that pupation site selection depends on interactions among conspecific and heterospecific larvae and on chemical characteristics of the breeding sites.This work was supported by Departamento de Investigación y Desarrollo [grant number DI 2006 ENL 06/07, Universidad de Chile], and Fondo Nacional de Ciencia y Tecnologı´a [FONDECYT 1020130]

“…Thus, D. melanogaster larvae prefer to pupate outside the breeding site, while D. simulans pupate on the fruit (Vandal et al 2008). How Drosophila larvae select pupation sites in the wild is poorly understood (Medina-Muñoz and Godoy-Herrera 2004).…”

“…Studies of D. mauritiana pupariation site preference indicate that this species prefers to pupariate in fruit (Vandal et al. ), and the similarity in phenotype between D. simulans populations from southeast Africa, D. sechellia , and D. mauritiana suggests that pupariation on fruit is an ancestral trait for the D. simulans clade. Selection of sites off‐fruit could have emerged in cosmopolitan populations as D. simulans emigrated from southeast Africa.…”

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.

“…Entry into “wandering” behavior in D. melanogaster is normally associated with complete larval exit from the food and movement up the sides of culture vials in search of a moderately dry pupation site. Many closely related Drosophila species choose to simply move to the food surface where they pupate(Vandal and Shivanna, 2007). In these species, the change in body position from the vertical head-down foraging position to the food surface appears to be the key behavioral transition necessary for survival through metamorphosis.…”

Developmental timing of a sensory-mediated larval surfacing behavior correlates with cessation of feeding and determination of final adult size

Controlled organismal growth to an appropriate adult size requires a regulated balance between nutrient resources, feeding behavior and growth rate. Defects can result in decreased survival and/or reproductive capability. Since Drosophila adults do not grow larger after eclosion, timing of feeding cessation during the third and final larval instar is critical to final size. We demonstrate that larval food exit is preceded by a period of increased larval surfacing behavior termed the Intermediate Surfacing Transition(IST) that correlates with the end of larval feeding. This behavioral transition occurred during the larval Terminal Growth Period (TGP), a period of constant feeding and exponential growth of the animal. IST behavior was dependent upon function of a subset of peripheral sensory neurons expressing the Degenerin/Epithelial sodium channel(DEG/ENaC) subunit, Pickpocket1(PPK1). PPK1 neuron inactivation or loss of PPK1 function caused an absence of IST behavior. Transgenic PPK1 neuron hyperactivation caused premature IST behavior with no significant change in timing of larval food exit resulting in decreased final adult size. These results suggest a peripheral sensory mechanism functioning to alter the relationship between the animal and its environment thereby contributing to the length of the larval TGP and determination of final adult size.
