Do adult Dubia grow anymore? I have some males and females that look like they are at or slightly over 2". Then I have some adults that look like they are barely 1.5"
Does anyone think it is important to only keep the largest adults for breeding?
I read some where, that you should introduce a new blood strane(sp?) to your colony every so often. Something about all the inbreeding making them get smaller as the generations go. I haven't tried it yet though, just something I've read on my beardy journey. :study: :study: :study: on the internet, of course.
I have read the same thing here and there, but there is no definitive proof inbreeding or genetics cause this. I think I saw once that someone mentioned they had some hisser adults that were significantly different in size, yet raised in the same container. That could be genetics, it could also be competition for food (less food would affect overall growth I would think) Still haven't seen any real experiments or results of those done to determine if this is something you could selectively breed or if it is a resource competition issue. Lot's of insects do vary in size in the wild even in the same species. I do suspect it is mainly a food source/climate issue, but that is only my belief. No scientific proof or research to back that up...
Over the years I have heard both sides from very informative people. I have both huge adults and small one. I also have 7 bloodlines in my colonies. I do it just incase but not for sure if you know what I mean.
