Studying fly culture

1.     Put flies into collector:
l   Pull up plugs a little so its easy to remove them with one grip.
l   Tap them on a pounding pad
l   Quickly transfer them into collector, with a funnel.
2.     Selecting for pairs
l   Put one pinch of yeast in all the vials, place them upside down.(avoid other flies contaminate)
l   Gunning them in the collector
l   Place all the slept ones onto the gas plate
l   Group them(16 female, a little less male eg.14) on the desk into diff groups/piles eg,5
l   Place different piles into tubes, label with respected color of the day.
l   Do the whole procedure in less than 5 min-otherwise males get brain damaged.

Notes:
l   Distinguish young ones: young male has brownish at back end of abdominal area.
l   Daily color code
l   Yeast for protein supply. (Just like female mosquito drink blood so they can ley eggs)

. Trials for drosophila mating
. Description:
Natso and Jessica are trying to compare the mating success between using virgin female drosophila and mated ones. 4 column of drosophila "couples" were placed under light, two in black background and 2 in white. Within each background group the column on the left are virgin females.
For 1 hour of observation, virgin groups showed significantly higher mating success. But more cases in white background.(only a test, really low sample size.)

Procedures:

1. put individuals together in one tube.
2. place them respectively into the background "seats"
3. start the timing thing and observe.
4. get out the ones started mating and mark the time it took on the tube.

Prepare CO2 gun:

1. make the main switch loose
2. turn AGA(blue) valve till there's reading.
3. turn on the switch of the pump
4. inject the gun into the tube and put the flies down
5. place the ones on the white board and collect them

Oh yeah~
