[I am putting these replies to Timothy R Hughes on public because I think

Flies under poorly controlled conditions (normal lab conditions)
generally live about 30 days, but if kept in low crowding
conditions or isolated, and with good food they can do much
better. Robert Arking and William Luckenbill at Wayne State,
and Michael Rose at Irvine have selected much longer-lived stocks.
