Raj Yashwantrao had joined the session and shared that he is interested in studying Auto-immune diseases in Fruit flies and for that he has started trapping fruit flies at home (New Delhi)

It’s been three days but not a single fruit fly has visited the bait as per Raj.
There were many suggestions on that don’t through the bait you might get some larvae.
Put duplicates

Use tomato as a bait.

Another discussion how to transfer Fruit flies from bait.?

To what the fruit flies are getting attracted to bait?.
What’s the chemical or component that fruit flies are smelling and get attracted to bait?.

Raj had also mentioned that the fruit flies were there in September but now they’re not their because of low temperature in Delhi.

But Aastha from Faridabad got one fruit fly. And if fruit flies were there in September so where have they gone from Delhi?.

Do they hibernate or if yes than where are they hibernating , where fruit flies have gone?. what’their life span?.

Aastha got one fruit fly in Faridabad so from where this fruit flies came?.

Why we are not able to see fruit flies now a days in Delhi or in Moradabad where temperature is 8’ to 22’?. Where fruit flies have gone? How do we attract them to bait?..

We had discussed about Over wintering, Insects can survive cold by slowing the life cycle as Sachin said…

Halt at Pupal stage in case of fruit flies.

Another interesting questions came up when sachin shared that Fruit flies can lay eggs every day and fruit flies can store sperms.

So what’s the gravid female fruit fly?. Whene we should it call it Gravid that’s gravid when it’s carrying fertilize eggs or even when also when it’s carrying sperm of male?.

How long fruit flies can store male sperm?.. Do they also prefer to mate with another male when it’s already having stored sperms from first mating?
