Can female Fruit flies lay eggs every day?.
Can female fruit flies stores sperms?.
How long can a female fruit fly store sperms?.

These were the questions were asked and Sachin from Dahanu Maharashtra is also interested in varify that do female fruit flies lays egg every day?.

Sachin has already placed bait at two places(One near Municipality Garbage bin and second at Backyard) and waiting for fruit flies to get attracted towards the bait…

We had also discussed further plan of Sachin…

A gravid fruit fly will be isolated from bait bottle and will be transferred in TRSV media bottle 1 than the after 24hrs. That fruit fly will be transferred from 1 bottle to another TRSV medium bottle 2 and subsequently FRUIT FLY will be transferred from 3 to 4 bottle and 4 to 5 bottle.

It has been seen as per Aswathy’s experience tha Gravid female fruit fly will lay egg with in 24hrs. That’s why 24hrs will be given to the fruit fly to rest in individual bottles.

Similarly a control bottle will also be made where another Gravid fruit fly will be transferred from bait bottle…

We had also discussed what are the gaps in this design…
This experiment should be start from the single line culture as Saida and Aswathy explained the importance of single line Cultures…

Moina another model system of CUBE, we haven’t discussed for so long about Moina.

Aswathy had joined the webinar and we had discussed how Aswathy got water fleas and how she water fleas were maintained by Aswathy and how she had lost them…

Approx 300Moina’s were brought by Aswathy from Fish selling shop.

  1. How to maintain the culture of Moina?.
  2. Why Moina model system is important with the aspects of science?.
  3. What’s the method to get Red Moina?.
  4. How do they trun red from colourless?.
  5. What’s the mechanism behind?.
    How to maintain the culture of Moina?
    What to feed them?.
    When and how to change water of Moina culture bottles?.

How to get Red Moinas?.
Why moina is turning red in low oxygen level?.
How.do.they sense the low oxygen?.
Do Moina change color gradually or does the colour change is sudden?.

So a graph was made in order to understand how do they turn red. From 1st day to 7th Day.

Bacteria in the culture bottle will be reproduced and hence no. Will increase and on the other hand also Moinas will also be reproducing and Level of oxygen will be reduced.
