R. ciliatus IncubationTeperature Determined Gender??

deinagkistrodon Dec 16, 2004 12:32 PM

I have recieved very mixed information about wether or not this is true. A number of different internet sources have claimed that an incubation temperature between 79 and 81 will yeild gauranteed female offspring. Yet many others (some seeming much more reliable), have claimed that it is assumed temperature might detetermine offspring gender but is unproven. Others still have stated that temperature plays no roled in determining gender.

I must have read atleast 30 hobbyist written care sheets over the past week. At least two thirds of them describing the species as one wich has a temperature determined gender. It is also my experience that show vendors will often have their 1 week old neonates labeled male sign or female sign. When asked how they made this determination they often respond "oh I incubated them to be female". Unless ofcourse they had manualy everted the hemipene.

Is there anybody who knows of some reliable published research that could shed some conclusive light on this issue?

I asked this same question when I returned from a rep. expo in October. There was a vendor there who had hatchlings labled female, and I asked him how he knew, and he told me he incubates for all female. None of his babies were labled male and this made me grow suspicious. The response I got was something like this....

**Some** vendors will claim they incubate for all females so they can sell more of their babies. Temp. sexing has not beem proven with cresteds.

That is the response I got (para-phrased). The best person to ask would probably be Anthony Caponetto @ www.acreptiles.com . That's where I go if I have questions that don't get answered here. Hope that helps. -Joe
