1 Neurobiology of Drosophila Ma/ng Behavior Jesse Balaban- Feld
2 ateman- Trivers Paradigm Choosy Females Expensive gamete (egg) High levels of parental care Indiscriminate Males Cheap, unlimited gametes (sperm) Low levels of parental care
3 osts of ma/ng for male Drosophila melanogaster ProducHon of sperm and ejaculate (Lefevre & Johnson 1962) EjecHon of ejaculate (Gromko et al. 1984) Courtship displays (Cordts & Partridge 1996) Act of copulahon (Partridge & Farquhar 1981) Sexual achvity significantly decreases life span of males hxp://i1- news.so[pedia- stahc.com/images/news2/sperm- Proteins- Could- Re InferHlity- and- of- the- Origin- of- the- Sex- 2.jpg
4 a/ng Decisions in D. melanogaster Males decide whom to court Females ulhmately decide who to mate
5 direct evidence for male mate choice in D. melanogaster ales preferenhally mated with rger females Byrne and Rice (2006)
6 direct evidence for male mate choice in D. melanogast ales shown to deliver more sperm to young, large, and mated females Lupold et al. (20 Only counted sperm numbers in females
7 he Male s Decision Males primarily depend on chemical (pheromone) cues Evidence exists for visual cues (size of female) If the male recognizes a female he believes will be recephve he will begin elaborate courtship display Most important part of display is the wing vibrahon song

11 ale assessment of female ma/ng status heromones Courtship 7- tricosene present on courted females Inhibits male courtship (Ejima et al. 2007) hxps:// CopulaHon ** cis- vaccenyl acetate (cva) transferred during copulahon Marks female as ferhlized, suppresses male courtship (Ejima et al. 2007) hxp://upload.wikimedia.org/wikipedia/commons/thumb/8/86/vaccenyl_acetate.png/200px- Vaccenyl_acetate.pn
12 dorant receptors Males detect odors through odorant receptors (ORs) Heteromeric odor- gated ion channels Or83b subunit (common) and a variable subunit confer ligand specificity cva subunit Or67d (Olfactory sensory neuron)
13 Lush binds cva, and in doing so undergoes a conformahonal change Most likely that achvated form of Lush acts as ligand (not cva) OSNs send axons to antennal lobe (olfactory bulb in mammals) cva OSNs target DA1 glomerulus
14 DA1 passes the signal to olfactory projechon neurons (PNs) DA1 PNs converge in a discrete region of the lateral horn It is spahally segregated from the region targeted by PNs that respond to fruit odors This could be the region that contains a Decision variable for achon selechon (to court or not?)
15 he Male Brain Singing is male specific Sex determined by fruitless (fru) and doublesex (dsx) Flies expressing male- specific fru M can sing dsx M isoforms do not express singing
16 synaphc achvity of all fru urons is blocked.all of urtship is suppressed
17 ru ~2000 fru- expressing neurons in both sexes GeneHc sex mosaic studies have shown specific regions (~20 neurons are important to song fru- P1 neurons If the fru- P1 neurons are masculinized in a female she sings Other neurons must also parhcipate
18 ru contributes to sexual differen/a/on Sensory processing AcHon selechon AcHon execuhon Pronounced behavioral differences between sexes are due to differences in circuits that select for alternahve achons Sensory and motor circuits may be common between sexes but fine tuned by fru
19 redic/ng ma/ng success Males need to discriminate female recephvity MaHng status Sexual maturity Conspecifics Behavioral studies have shown males can learn from experience Less likely to court mated females following rejechon Also for heterospecifics
20 earning in Mushroom body Likely site for experience- dependent responses to pheromones Receives input from olfactory and reinforcement pathways Specifically γ neurons (express fru) are site for plashcity If disrupted, courtship learning is supressed
21 onclusion Insect and mammalian olfactory systems use dishnct receptors but they process the informahon in a similar manner Studying Drosophila s complex mahng decisions can help to reveal how the computahons performed by defined neural circuits can guide complex decision making and behavior SHll much to be learned
