HBCSE Webinar

A front-end for HBCSE web conferencing server. You can create your own rooms to host sessions, or join others using a short and convenient link.

Please click on the HBCSE Webinar above to join the CUBE ChatShaala
Timing:5.30 pm to 9.30 pm
As we do it daily, CUBE chatShaala will be starting at 5.30pm and as a continuation of it, from 8.30pm, there will be Mango-Mapping workshop.

Users need not join from any other link.
MangoMapping will be a part of CUBE chatShaala itself.

Looking forward to your participation.
Thanks

Interesting we got to know that how temperature can affect the life cycle of fruit fly as @kshipra from Dumka Jharkhand had put a bait(apple pices in a bottle) on 13/12/2020 to attract or trap fruit fly…

One gravid fruit fly got trapped and following are the observations.
13/12/2020 : one gravid fruit fly got trapped
18/12/2020 ; Larva was seen (after 5 days), fly got escaped
25/12/2020 : 10 Larvae of 3mm size were observed

Already passes more than 15 days and still no pupa no adult fly was seen…
IMG_20201225_211621 The effect of temperature on the life cycle of fruit fly

We had compared the temperature of Thrissur Kerala and Dumka Jharkhand
And how many do adults emerges in single line Culture of fruit fly from Aswathy cube home lab.

But how does temperature affect on the life cycle??low temperature , lower metabolic rate??..

Another interesting questions came up that if there’s a delay in the life cycle due to low temperature so would there be any effect on the life span of fruit flies?.

Lifecycle Vs. Life span
What do we mean by life cycle and life span?.

Another question how do we go about observing that yes temperature is effecting the life cycle?.
IMG_20201225_211611 What’s the optimum temperature?..
Can delay in life cycle effect the life span of fruit fly?..

Three preposition were made

  1. Increased life cycle than flies will have shorter life span

  2. No effect on the life span of fruit flies

  3. Increased life cycle than flies will have longer life span…

:memo:Does temperature affect fruit flies?
Insect development and metabolism is affected by temperature, Effect of temperature on the developmental time of various life stages. The duration of the egg stage varied significantly between these two species at each temperature.The metabolic rate of D. melanogaster was measured at 20 °C, 25 °C, and 28 °C in an isothermal calorimeter.

:memo:What is the optimal temperature for fruit flies?
At 18°C, no female oviposited. The survival rate reached maximum at 24 - 33°C and decreased at higher or lower temperature. The lower developmental thresholds, thermal constants and lethal high temperatures for different life stages of the fly were also estimated.

:memo:How long do fruit flies stay alive?

40-50 days
Contrary to popular myth, fruit flies live longer than 24 hours. Under good conditions, they can live up to 40-50 days.
