Come and knock on my door….

Adult count: 3

Not a recipe for more beetles

Only a weirdo would let this get to them, but why can’t I keep these adult beetles alive?  Obvious possibility is that cous cous isn’t preferred (but they have gone through a full cycle on it). Transferred all three to corn meal… at least that’s something that *I* would eat. There are larvae in the cous cous though that appear to be getting bigger and are definitely alive.  Perhaps there are strain differences in how long the adults last. I don’t see any obvious fungi, but I didn’t have my single-celled glasses on.  Or about a million other variables.  Maybe those adults are just worn out.  Maybe its the voices of all those hundreds of little larvae and the adult beetle’s inability to finish a thought or have time to themsel…. ahem.  Right.  Back to teaching.

Mmmmmm… cornmeeaal

Note to self: added more than a pinch of baker’s yeast too.  Just so I can say they are eating their Wheaties.

[Jeff, chase down: how many strains of T. confusum or T. castaneum are there?  Are the differences between strains within species as dramatic as, say, between C57Bl/6 and BALB/c mice?  Information specifically on strain differences in lifespan of adults?]

9-30-13 – (PDF) Dense paper on reproductive differences that develop as inbred strains are developed.  No mention of adult lifespan per se, and its pretty dense, but also obvious that pretty impressive differences in reproductive capacity shows up fairly quickly.  Another jackpot: PDF.


About SubOptimist

I am an Associate Professor in the Science Department at Georgia Perimeter College, Clarkston. I teach introductory biology courses at both the majors and non-majors level in addition to microbiology. Previous to that I spent 7 years as a postdoctoral researcher on different viruses. While I don't miss being on the "grant treadmill", I think better when I write and miss writing up data for papers and grants; this blog helps me with that a little. And sometimes my kids' insanely funny and cute antics need to be shared with the world. Any view expressed in this blog is that of me personally and not Georgia Perimeter College or the GPC Clarkston Science Department.
