hello all, Ive been wondering what temps you all use for your burm clutches mine are about 90 now what would be the max for these?

Based on my own maternal incubation data I have compiled over the years, the average egg mass temp for all of my incubating females was 92 F. This usually will vary by 0.5 to 1.0 degrees during the main incubation period, dropping off during the last week. However, the highest egg mass temp I am aware of for a maternally incubating female burmese was around 94 F. This was a very short term temp spike, and most of the other available data is in line with the 92 degree average. Most people use 90 for artificial incubation and get good results. Definitely don't let them get below 90, and be certain that your temp measurement device is accurate. Good luck.

Very good info Kelly. I've always heard that the eggs should be between 88 and 90. What were the ambient temps during maturnal incubation? I'm wondering how much the female was able to raise the temps.

Randy,
It appears that most python species attempt to maintain the egg mass temps between 86 and 90 degrees, with the physiologically thermoregulating species in the 88 to 90 degree range. The molurus complex has the highest maternal incubating temp of any python species with bivittatus apparently having the highest at the 92 average. The Sri Lankan molurus that I had hatch a couple of years ago were maternally incubated at an average temp of 91. I would really be interested to see maternal incubation temp data on mainland molurus from northwestern India and Pakistan. Due to the higher latitude range of this subspecies, I would expect these females to have the greatest temp control of any python species. I agree with you that for the majority of python species, the 88 to 90 range is about the best.

For my maternally incubating females, I shoot for an ambient temp around 85 or 86 with a 90% humidity. As you know, the balancing act is to not go too high, as the female cannot cool the egg mass if temps go above the critical high, and not too low, as this will cause her to expend an inordinate amount of energy keeping the egg mass temp at the correct level. I have seen reports where incubating female burmese were able to maintain the egg mass at 92 with an ambient temp in the mid 70’s. This makes sense, as the night temps in the tropical range of this species would definitely fall into the 70’s.

Thanks Kelly, I've never left a clutch with a female but would like to in the future. We have to run a humidifier just to keep the room at 60%, so there's no way we could get the humidity in the cage to 90%. I guess we will keep using the incubator until we can get out of Colorado.

I have some eggs in the cooker - two bins (sterlite) of burmese eggs.

One bin is reading at 88 degrees - the other is between 91 and 91.5. This is the closest I can get these. The one at 88 has fallen below to 87 or 87.5 a couple times, but if I raise the temp of the incubator it brings the first bin to 92 which I'm concerned is too high for full-term incubation. Until I saw this post I have always seen 88-90 for egg incubation of Burmese eggs?

Any input is appreciated.

Rick

thanks for the info!I wanted to let her incubate the clutch but the enclosure she is in doesnt hold humidity with any consistency but will try maternal incubation in the future.
