“…While our results suggest that both mating states strongly relied on fruit‐derived odours for long‐range attraction, the short‐range olfactory preference for oviposition substrates has been found to be mediated through a single olfactory channel in which apple and banana odours induce very similar physiological responses (Dweck et al ). Moreover, as other studies have shown that oviposition behaviour is governed by a combination of olfactory (Ruebenbauer et al , Dweck et al , Hussain et al ), visual (Del Solar et al ) and gustatory information (Clyne et al , Thorne et al ), we expect that the change in the use of short‐range cues and the lack of additional sensory cues lowered the interest of the mated females to select among our odour sources (Supplementary material Appendix 1 Fig. , Table A3), and eventually removed the competitive interactions between apple and banana odour sources in our mixed resource environments (Fig.…”

Mating affects resource selection and modulates associational effects between neighbouring resources

Associational effects occur when the attack rate on a resource depends on neighbouring resources in the environment. These effects are predicted to result from mismatches experienced by the consumer organism in resource selection along hierarchical search levels. As resource selection depends on sensory information used during search behaviour, we expected that different physiological states of an insect might modulate the outcome of associational effects due to differences in resource selection. We used Drosophila melanogaster, as a model organism for olfactory-guided behaviour in insects, to study the effects of mating induced behavioural changes on associational effects between two alternative resources. We found that mating has no effect on the ability of D. melanogaster to locate resource patches, but rather affects the perception of the resources within the patch. Consequently, we only found associational effects in the experiments with unmated females and not in the experiments with mated females. Our results suggest that the lack of associational effects for mated females resulted from changes in the use of short-range olfactory cues, leading to random selection among the resources. In conclusion, our results suggest that the physiological state of an insect modulates associational effects by affecting resource selection rates within the patch.

“…It is important because oviposition sites in nature vary in quality, affecting fitness of offspring. In the genus Drosophila, many factors influence OSS, including texture of the medium (David, 1970;Rockwell and Grossfield, 1978), color of the substrate (Carfagna and Lancieri, 1971;del Solar et al, 1974), gregariousness (del Solar and Palomino, 1966), larval conditioning of the medium (Dawood and Strickberger, 1969;Weisbrot, 1966), larval density (Lewontin, 1955), and competitive interactions between species (Barker, 1971;McKenzie and Parsons, 1972;Soliman, 1971). The adaptive nature of OSS is clear for some of these factors, especially in the case ofintra-and interspecific competition.…”

OVIPOSITION SITE SELECTION BY DROSOPHILA MELANOGASTER AND DROSOPHILA SIMULANS

The effects of texture and larval residues in the medium on oviposition site selection (OSS) by Drosophila melanogaster and Drosophila simulans were studied. Drosophila melanogaster laid over 95% of its eggs in sieved medium (vs. unsieved medium); D. simulans laid all of its eggs in sieved medium. Surgical removal of antennal segments, and of fore-, mid-, or hindtarsi did not affect this result, indicating that sense organs involved in discriminating between sieved and unsieved medium are not confined to only one of the tested structures. In a "multiple choice" experiment, females were allowed to lay eggs in sieved medium of three types: unconditioned (fresh) medium, medium conditioned by D. melanogaster larvae (i.e., medium containing larval residues of D. melanogaster), and medium conditioned by D. simulans larvae. This choice experiment was performed with D. melanogaster and with D. simulans, using three densities of females (10, 20, and 40 per experimental unit). Both species laid more eggs in unconditioned medium than in either of the conditioned media, and density had no effect. D. melanogaster laid more eggs near the edges of food patches than in the center, whereas D. simulans showed no preference for edge or center. Under crowded conditions, both species survived at a higher rate in conditioned media (egg-to-adult survival) than in unconditioned medium, leading to the anomalous conclusion that females of these species seem not to maximize the survival of their offspring. This anomaly was partially resolved by the finding that medium already containing larvae gave lower survival rates than unoccupied medium.

“…The nociceptive system mediates ovipositional avoidance in response to capsaicin. Drosophila ranks egg-laying sites via sensory modalities 22 , including vision 23 , gustation 24 , olfaction 14 , and nociception 25 . Next, we attempted to identify potential sensory modalities responsible for the ovipositional aversion to capsaicin.…”

Plants generate a plethora of secondary compounds (toxins) that potently influence the breadth of the breeding niches of animals, including Drosophila. Capsaicin is an alkaloid irritant from hot chili peppers, and can act as a deterrent to affect animal behaviors, such as egg laying choice. However, the mechanism underlying this ovipositional avoidance remains unknown. Here, we report that Drosophila females exhibit a robust ovipositional aversion to capsaicin. First, we found that females were robustly repelled from laying eggs on capsaicin-containing sites. Second, genetic manipulations show that the ovipositional aversion to capsaicin is mediated by activation of nociceptive neurons expressing the painless gene. Finally, we found that capsaicin compromised the health and lifespan of flies through intestinal dysplasia and oxidative innate immunity. Overall, our study suggests that egg-laying sensation converts capsaicin into an aversive behavior for female Drosophila, mirroring an adaptation to facilitate the survival and fitness of both parents and offspring.
