Hello all, I have manged to find a scientist in ants to examine the dead samples. Here is the reply.
'Hi yes sorry for not getting back to you earlier. I incubated the ants and found no evidence of entomopathogenic fungi, there was some surface contamination by pin moulds but no insect pathogens that I could see, and certainly no evidence of the surface structures you observed earlier. So I think that rules out fungi. If there was an infection then it could be a protozoan/ microsporidian but these are often sub lethal and difficult to detect.'
So it is still a mystery what killed the ants.
In fact I noticed that when the ants die, the bits also dissappeared. I guess failing to boil the insect might be the culprit. Hard lesson learnt. Has anyone ever throw live insects into the colony for feeding? I wonder which type of insect would be safe to do so?
Also, do you need to boil those dead, dry flies that I bought from Antstore?
