“…In most strains of four species ( D. ananassae, D. bipectinata, D. melerkotliana , and D. biarmipes ), larvae pupated close to the food surface at 20 °C, far above the surface at 24 °C, and mostly on the medium at 30 °C. Similarly, Schnebel and Grossfield (1992) found that 12 species/subspecies of Drosophila tended to pupate close to the food when temperatures were high and that a subset of these pupated high on the vial sides at lower temperatures. However, these pupation height differences may not depend on temperature per se, but rather on correlates of temperature, such as the moisture content of the food or the humidity of the air.…”

Environmental temperature strongly affects physiology of ectotherms. Small ectotherms, like Drosophila, cannot endogenously regulate body temperature so must rely on behavior to maintain body temperature within a physiologically permissive range. Here we review what is known about Drosophila thermal preference. Work on thermal behavior in this group is particularly exciting because it provides the opportunity to connect genes to neuromolecular mechanisms to behavior to fitness in the wild.

“…Moreover, larvae selected sites on fruit when soil water content was low, suggesting that they chose sites for pupariation that minimized the probability of desiccating in dry conditions and of rotting in wet conditions (Sokolowski et al 1986). Other studies have documented the effects of density (Ringo and Wood 1982), light (Rizki and Davis 1953;Schnebel and Grossfield 1992;Paranjpe et al 2004), pH (Beltrami 2010), and the presence of con-or heterospecifics (Beltrami 2010) on pupariation site choice.…”

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.

“…As both foraging path length and pupation height are to are large extent regulated by the for gene, this indicates that A. tabida may reduce the expression of this gene. Pupation site in unparasitized Drosophila larvae is known to depend on moisture, temperature, density, phenotype/ genotype (rover vs sitter) and species (Sameoto and Miller 1968, Barker 1971, Sokolowski et al 1986, Schnebel and Grossfield 1992. The decision of where to pupate seems to be taken during the wandering stage which occurs a few hours before pupation (Riedl et al 2007).…”

Few examples exist where parasites manipulate host behaviour not to increase their transmission rate, but their own survival. Here we investigate fitness effects of parasitism by Asobara species in relation to the pupation behaviour of the host, Drosophila melanogaster. We found that Asobara citri parasitized larvae pupate higher in rearing jars compared to unparasitized controls, while A. tabida pupated on or near the medium. No change in pupation site was found for three other species. A follow‐up experiment showed a non‐random distribution of parasitized and unparasitized pupae over the different jar parts. To test the adaptiveness of these findings, we performed pupal transfer experiments. Optimum pupation sites were found to be different between host individuals; wall individuals survived better than bottom individuals, but bottom individuals did worse at the wall. Two parasitoid species that alter pupation site significantly showed high rates of diapause at their ‘preferred’ pupation site. For one of them, A. citri, pupation occurred at the optimal site for highest survival (emergence plus diapause). From literature we know that pupation height and foraging activity are genetically positively linked. Therefore, we implement a short assay for rover/sitter behavioural expression by measuring distance travelled during foraging after parasitism. For one out of three species, foraging activity was reduced, suggesting that this species suppresses gene expression in the for pathway and thereby reduces pupation height. The parasitoid species used here, naturally inhabit widely different environments and our results are partly consistent with a role for ecology in shaping the direction of parasite‐induced changes to host pupation behaviour. More parasitoids are found on the wall of the rearing jar when they originate from dry climates, while parasitoids from wet climates pupate on the humid bottom.
