Hello Mika,
I never heard about intranest maiting by Oecophylla, so I think that you´ll stay with a non-mating queen in youryoung colony. Interessting that you get a nest with a queen which had not been cmated, maybe there was something going wrong during the copulation, I don´t know.
Did you hold you colony all times with a temperature of nearly 30°? It could be possible (just a guess) that the eggs will determate to males with this temperature. The best temperature - I don´t think that I could say this by having expirience with ONE colony - but I try to explain how I keep my ants.
I´m having a special lamp (kind of energy saving lamp) which light is very similar to the sunligh (nearly over 90% of the natural full spektrum). The lamp has 23W (thats 120 Watt of a normal lamp) and have a good heat emmission. Added to this lamp I´m using a halogen lamp (in future also full spektrum). Thats are the only heating sources that I use at the moment. I plan on doing to test a heating cable wrapping on the plant trunk because the dry heating source of the radiator is not the best way. So the ants have normal room-temperatures except the two spheres of the lamps, where they mostly build their nest.
Hope this could helped you forward. Otherwise just ask again (maybe send me a pm that you answered in this thread - it was luck that I saw this post)
best regards
Bianca
