Dubia Experiment

Any more updates?

I have died and gone to heaven. I love these sorts of experiments. I think the quest for more knowledge and information is always a good thing regardless of how many tried and true findings have been made in the past. It certainly doesn't hurt to add to the studies. So the experiment's goal is to figure out whether roaches can still reproduce under other than optimal conditions for breeding? Awesome!! Can't wait for the results!

Speaking of which, any updates???? I'm seeing this thread for the very first time today lol (been living under a rock lately)

experiment is pretty well done because temps are rising and I have no intent of putting them in air conditioning to keep temps down...

My findings are that at 64 degrees the dubia never produced less than 2000 nymphs per month.

I also put 15 dubia nymphs in the freezer for 10 hours and they were alive and active within 2 hours. So they survived 28 degrees for 10 hours.

This species is much more hardy than people give them credit.

The Roach: able to survive extreme heat, cold, radiation, everything but your local mailman :mrgreen:

So, what were your February and March numbers?

Correct me if I'm wrong, but you started out with 675 adult females total, and each one averaged about 16 nymphs over four months, or 4 per month.

The number I always hear ballyhooed for females giving birth is 20-40 per month. Yet your females didn't even birth that many over four months. I appreciate that you don't want to air condition them to continue the experiment, but I don't see where your results can prove that they can successfully breed at 64 degrees F. How do you know the results didn't just demonstrate that their metabolism really slows down at that temperature?

most people will say that dubias "average" 20-40 offspring per month....

I have never heard anyone separate a 100 females and count each one's output over any time frame....

Yes it is blatant that they created offspring (ie act of breeding) during the set time frame....


Measured time frame was 5 months. Total of offspring exceeded 12000.

This was not an experiment to test metabolism....

their food intake, die off rates etc were never measured.

This was a black and white experiment that proved dubia roaches can reproduce and will hatch offspring at 64 degrees. Mating, egg sacks and even hatching were all observed

I stopped offering information because people were trying to imply findings that were not even being measured.

Facts found will be useful to many....

The dubias did not all die from being maintained at 64 degrees for 5 months.
The dubias created offspring during that 5 months while at 64 degrees.
