>Among the insecticides, the neonicotinoid imidacloprid is one of the most
effective in interacting synergistically with fungi.
When one cites statements such as this, it helps to understand the
mechanisms involved. For instance, the synergism between Imd and fungus
for termite control is due to reduced grooming by the termites in response
to Imd, which then allows the fungus to penetrate the cuticle. This is a
physical effect, and should not be confused with immune suppression.
I do not know the mode of action for thrips and fire ants, but in general,
any stressor will increase the effectiveness of a bio control agent. I'm
not sure that we should single out any single insecticide.
