where can i find some glass jars to culture fruit flys? as i rather just clean out a couple glass jars then have to keep buying plastic containers. thanks
yuri said:One thing to be keenly aware of is the possibility of chemicals leaching from plastics. If you think washing gets rid of the problem, it actually helps some chemicals leach out. When you consider that the fruit fly medium is 'wet', then there may be chemicals leaching into the medium and maybe into the fly larvae, and maybe into your frogs. Well what are a few more chemicals going to do to your frogs? Read up on endocrine disruptors.
These interesting chemicals influence hormonal activity in a variety of ways. In humans they have been linked to increases in certain cancers, decreased sperm counts, developmental problems.
This is why I use glass mason jars. For the top I use unbleached coffee filters (some bleaching agents leave residues like dioxins - another good one to read up one).
So, when you throw out your plastic fruit fly containers, you are just throwing the problem somewhere else. It takes a very long time for the plastics to break down and they continue to leach out chemicals. You might be thinking this is bunch of bull, but look into the problems with male America Alligators and how they are affected by endocrin disruptors. Pretty scary.
Okay, frog production. I still think you need to make side by side comparisons in order to get a better answer than just guessing.geckguy said:I was refering to frog production, his frogs lay many more eggs, I have no problem with fly production.
