In all experiments except those for RU486 calibration, we used our laboratory stock of outbred wild type Drosophila melanogaster, Dahomey, which has been cured of Wolbachia by tetracycline treatment 1 . Flies were maintained in large population cages with overlapping generations at 25 °C with a 12 h: 12 h light: dark cycle. UAS-ArcAβ42 and elavGS transgenic flies were backcrossed into w1118, as reported in 2 and wDah; dilp2-31,5 deletion mutants and Wolbachia-positive white Dahomey (wDah) controls are those reported in 3 . All genetic constructs were back-crossed into the genetic background of their control for at least six generations before experiments were performed.
For all experiments using adult flies, other than food choice, flies were reared on sugar, yeast food (1SYBrewer’s; 1SY) as described in 4 for lifespan experiments. Egg collections were used to synchronize fly age as described in 5 . Flies for the food choice assay were reared in a medium containing, per liter, 80 g cane molasses, 22 g beetroot syrup, 8 g agar, 80 g corn flour, 10 g soya flour, 18 g yeast extract, 8 ml propionic acid, 12 ml nipagin (15% in ethanol).

Wild type Dahomey flies were housed and maintained as described in Bass et al. (2007) [7] (link). The chico1 allele is maintained as a balanced stock that has been backcrossed to the Dahomey outbred laboratory population as described in Clancy et al. (2001) [21] (link). snw, ry506, to1 (takeout) flies were a gift from Brigitte Dauwalder. All flies were maintained at 25°C, 65% humidity, on a 12h∶ 12h light∶ dark cycle. Unless stated otherwise, all assays used mated females at day 7 after eclosion. Day 7 was chosen because the flies are still young, but several early adult developmental processes have been completed [39] (link). All flies were reared for assays at a standard density, as for lifespan studies [40] (link), and allowed to mate for 48 h post emergence before being sorted by sex, under light CO2 anaesthesia, into 30 mL glass vials containing 7 mL food.
The DR food medium contained 100 g autolysed Brewer's yeast powder (MP Biomedicals, Ohio, USA), 50 g sugar, 15 g agar, 30 ml nipagin (100 g/L), and 3 mL propionic acid made up to 1 litre of distilled water. The full fed food contained 200 g autolysed yeast powder, 50 g sugar, 15 g agar, 30 ml nipagin (100 g/L), and 3 ml propionic acid made up to 1 litre of distilled water [7] (link). In the diet comparison experiment, this medium is labelled SYBrewer's. CSYExtract was made according to [15] (link). This was made by co-diluting sugar and yeast extract (Bacto Yeast extract, B.D. Diagnostics, Sparks, MD) in a binder of cornmeal (80 g/L), bacto-agar (0.5%) and propionic acid (10 g/L). The 1× concentration contained 10 g/L sucrose and 10 g/L yeast extract.
For DR lifespan experiments, flies were maintained 5 per vial at 25°C, 65% humidity, on a 12h∶ 12h light∶ dark cycle. Proboscis-extension assays were performed for 60 minutes at 5-minute intervals, 4 hours after lights-on at 21 separate days across the lifespan experiment.

Experimental flies were raised at a standard density of 400–450 eggs per 200-ml bottle [52 ] on standard SY medium (1,000 ml distilled water, 100 g autolysed yeast powder, 100 g sucrose, 20 g agar, 30 ml Nipagin (100 gl–1), 3 ml propionic acid). Adults were collected over a 24-h period and transferred without anaesthesia to fresh SY food for 48 h and allowed to mate. Females were then collected using light CO2 anaesthesia and assigned randomly to the food regimes (Table S1). All experiments were done with mated females. Flies were kept on 35 ml of food at an initial density of 100 individuals per 200-ml bottle and transferred without anaesthesia to fresh food every 2–3 d. Deaths were scored 5–6 d a week and initial sample sizes (n0) were calculated as the summed death and censor observations over all ages. To minimise any density effects on mortality, two bottles within cohorts were merged when the density of flies reached 50 ± 10. To standardise the effects of parental age on offspring fitness [53 (link)], parents of experimental flies were of the same age and reared at a constant density.

The study was conducted on the male adult or post-eclosion D. melanogaster flies at 10 days of age at the time of study initiation following previous studies on bang-senseless (bss) D. melanogaster models (parabss) and novel anti-epileptic treatments.15 (link),16 (link) The Drosophila models of the bang sensitive (BS) family used in the study were the bang senseless or bss1 mutants of the paralytic gene (parabss1),48 ,49 (link) and the wild-type strains used as controls were Oregon-R or OrR and Canton-Special (CS).49 (link)-51 (link) Male flies were used as a previous laboratory study has shown differences between female and male bss Drosophila because the parabss is located on the X chromosome, and heterozygous parabss/+ female Drosophila have significantly decreased recovery times.52 (link) Only animals that underwent seizures were included in the study during behavioral (convulsion and learning/memory tests) and histological assessments.49 (link)The bang-sensitive mutant flies (parabss1) obtained from Prof. Richard Baines laboratory (University of Manchester, UK)48 ,49 (link) were used, and the wild-type flies ie, OrR (BDSC stock #25211) and CS (BDSC stock #64349), were obtained from Bloomington Drosophila Stock Center, Indiana University, U.S.A, and all the stocks were delivered to the Institute of Biomedical Research for culturing into sufficient stock colonies. The bss paralytic (para) D. melanogaster mutant flies used in the study have a gain-of-function mutation in the para sodium channel gene located at the para locus in neurons of the mutant flies.52 (link)-54 The flies were cultured on a standard yeast/cornmeal/agar diet (distilled water, 6.65% cornmeal, 7.15% dextrose, 5% yeast, 0.66% industrial agar supplemented with 3.4 mL/L propionic acid, and 2.2% nipagin) for Drosophila flies following previous methods,55 (link),56 (link) (Supplementary file 1). The flies were kept in incubators at 25°C, 65% humidity, and on a 12-h light/dark cycle (Fly incubator with programmable day/night cycle; Powers Scientific Inc., S33SD, USA). Flies were transferred to fresh plastic fly vials (Genesee Scientific, 32-116, USA), every 3 days, and fly density was kept to 10 flies per plastic fly vial (Genesee Scientific, 32-116, USA).

Hydrogels were prepared by mechanical stirring of BNC pulp with 1% of the gelling agent Natrosol® (hydroxyethyl cellulose), 0.18% and 0.02% of the preservatives Nipagin® (methylparaben) and Nipazol® (propylparaben), respectively, and 5% of the humectant propylene glycol, all measured in w/w relative to the total mass (100%) of the hydrogel. Standard BNC hydrogel containing 1% dry mass of BNC was produced, named BNCH. From BNCH, formulations were prepared by adding 1.2, 2.4, and 3.6% (w/w) propolis extract (EPP-AF®) provided by Apis Flora Company (Ribeirão Preto, São Paulo, Brazil). The samples were named BNCH/P1, BNCH/P2, and BNCH/P3, respectively. Propolis concentrations were based on the study of Berretta et al. (2012) [24 (link)]. Natrosol® hydrogel was also produced as a control group and named BH.
For photodynamic inactivation, BNCH/P1 hydrogels were reproduced with the addition of MB at concentrations of 0.01 and 0.1% (w/w), originating samples BNCH/P1/MB1 and BNCH/P1/MB2, respectively. Formulations containing only BNC hydrogel and MB (BNCH/MB1 and BNCH/MB2) were also produced, keeping the same reagent concentrations.
