Ok, I have a adult male Brazilian, he went off feed a little over 3 weeks ago and has no interest in feeding what so ever, he was eating every 2 weeks for several months and suddenly stopped. My temps have not changed much and are in the range of (ntl) 77 (dth) 84 average 82 during day. The female is in close proximity and is feeding weekly quite voraciously to be honest. I have no interest in breeding them this season, the female is 1380g (heavy enough in my opinion) but I wanted to wait till next season. I was wondering if they go into season this late, I have bred Brazilians in the past but they went much earlier (DEC/Jan) both times. I believe this is the reason he went off feed, he's got some girth to hold him over for quite awhile, so no worries there, I was just wondering about the aseasonality (not a "set" breeding season)of rainbow boas

Thanks,

since I got the male from you he may have been exposed to your temp induced biorhythm, he was old enough to breed when I received so I am particularly interested in your response.

although at 1380g I believe she is heavy enough, my goal weight to breed her is 1600g. I will not breed her until she reaches this weight and by the way she's been eating she will surpass this weight by next season, I am more concerned about the males fertility period, I would want to condition the female to breed in DEC/Jan unless the male can be manipulated as well, that's why I am interested in his fertility period and or if males can be fertile more than one time a year and or how important temp flux are in regards to spermatogenesis.

Yeah, while the female may be large enough, IMO, 1600 grams is the minimum correct weight. She may be putting off those sweet smells the males like so much even though she does not weigh that much. They can go late, really depends on the cooling cycle, the cooling seems to be improtant to generating sperm but I have not seen males that would only go at a certain time. Mine always go late, I believe it to be related to the warmer California weather. I have wait till later in the year to attain the required cooler temps. I saw Tommy and Bullseye locked up this very morning in a water bowl.

Thanks Dave, yeah I live in NJ that's why most of my snakes go earlier, but this pair came from Jeff and where adults and where subjected to his weather patterns and I have noticed with my adults snakes once their biorhythm is set its hard to change.

Well, I have to admit, all the BRB's I have acquired as adults (except for one) have been raised locally. The one exception is Eve, she grew up in the jungles of Surinam. She doesn't speak one single word of english. Heck, she even bites in Dutch!

Dave, if you know when eve's parturition date was, you could figure out based on average gestation data when her "wild" fertility period was, I have heard that wild adult Boids reproductive biorhythms can take years to reset to a different pattern, this is why I am so interested in Jeff's breeding season even though they are captive bred they still may adhere to "old" seasons and not respond to me cycling at a different time of year.

Frank Roberts

Don't have dates but from the size of the babies, either very late 2006 or very early 2007 either of which puts breeding at mid summer. Ah well, guess I'll have to work on her. I'm gonna make her wait until next fall/winter, will have to wait and see.

That intel was from books etc...old ones lol...I would rather wait and see your results with eve next season, they may acclimate faster than people think.

doesn't Jeff keep his in Vision cages and tubs and with no night-time drop in temps. except for cooling?

In theory the cold side of cage or tub is actually room temp. or ambient right? So since I live in LA and summer is 6 months a year and my temp. gradient will more than likely be somewhere like 78-81 (80 on hot spot) and my snakes seem to like it under the coconut on the hot side so in theory if I only reduce temps during cooling the snakes should feel the difference in temps since 10 months out of the year the temps stay exactly the same and during cooling-these are the only times the temps will change thus tricking them and letting them realize much easier that there is a drop in temp at night during this time.

What's everybody's thoughts about temps and cooling?
Bob

I think temp drops are critical for certain species, but I also believe we don't know as much as we think, we use variables that get results without experimenting to see if good results could be gotten another way, I and several of my friends have breed many colubrids with 100 percent fertility without hibernation, although all of these where southern or western snakes, Boids there is a clear pattern from my studies that show good results with thermal cycling, but I would like to study other data with no cycling, but it's scarce, people don't like failing, I know that a 70 to 90 cycling is not required to breed retic's, I have males be fertile without cycling and one wild caught needed 75 degrees, may be more individualistic then we know and captive bred f5's may be very different from f1's, technically we don't know crap to be honest.

My pair has another year before they're ready.

I'm going to let them see if they'll go at it without any cooling.

Can you wait that long?

And Bob, you live in LA as in Louisiana, the greatest state in the US of A or LA as in Almost as cool California?

since we have an occassional hurricane very rare though we have to evacuate but the things I hate about Louisiana.
1-rude people (southern hospitality doesn't apply to most people around here)
2-the worst streets in AMERICA!!!
3-the worst politicians in the US
4-one of the worst school systems in the US
5-very hard to pump gas in N.O. without someone asking u for money (dead serious)- probably cuz everybody and their crack addicted mom is on welfare-haha no joke
6-having fun in the French Quarter isn't really fun anymore with all the drunks and violence
7-cops need new training or a new system or we will rank among the worst crime communities in the nation just look at the number of crimes where the REFUGEES went-sorry Texas but keep 'em all please

and the list could go on and on but if I didn't have a 6 year-old son who meant the world to me I would definately move with no hesitation required. I might even buy a ticket or two to the Lockwood and Colling Museum's
Bob

Ah the joyus cities of Metairie and Kenner!

My old stompin grounds... I'm a Tulane alum.

Glad to know there are other herpers into BRBs in the region. It goes without saying that you're probably a part of LGCHS?

what is the LG.HS? lol Tulane-yeah you right but I'm no LSU fan either but Tulane is better hands down. I live in Metairie about 2 streets away from the Kenner cops so I know what you are talking about. Schools I attended were St. Lawrence the Martyr (closed down awhile back), Curtis for a couple of years and attended Bonnabel (had honors classes though) for high school. Went to UNO for a little while and just didn't like it (just didn't want to be in college at that time).
Bob

is my passion/hobby, I have been studying Reptiles and Amphibians for over 30 years, had my first snake by 6, my first python by 11, first crocodilian by 13 and so on, I have never been without some kind of critter since then, I caught my first snake at 3, needless to say my mom thought I'd "grow" out of it and well I never did. I have learned more from my and other peoples personal observations than from the literally hundreds of books I have read, so yes I have time...

Thanks,

there is almost no way not to have a certain amount of cycling unless in a completely controlled microenvironment, we truly don't know if and how much temperature variation is needed to successful propagate most species, so any data with temps whether successful or unsuccessful is worth looking at.

Frank Roberts

Frank,
...I do think your female is putting out pheromones that have caused the male to think about breeding season. My cooling gets changed every year depending upon local weather. We had a very warm december here this year and so cooling the snakes was delayed and they have been breeding the last two months.
Jeff

>>Dave I'm correcting myself lol

>>Frank Roberts

That's what I figured and if your cooling gets changed every year then when my cooling period arrives male should respond and means they (rainbows are truly aseasonal and will reset his "clock" to follow, which is what I was trying to figure out, not much Intel on this species reproductive biology.

Thanks a million,
