about testing feeder insects for parasites, and here is his reply (I'll just paste it here, don't want to misinterpret anything as I am not a biology person):
Regarding your other question -
I wish it were as simple as that! Many of the worms exist in larval forms in the paratenic host, it is only the eggs that come from the adult worm which is normally found in the final host. Therefore, you "may" find some eggs with a concentrated salt flotation, but you would need to be very confident identifying eggs. For the larval forms, that is more difficult. YOu have to set up a Baermann Filtration system to harvest the larvae and then identify them. I did this for months in Khartoum with camels and it is not easy. What i would sugegst is we do some research about the parasites you are most worried about and check their life cycles and see how they reach the final host. You may be able to "clean" the feeder insects and ensure they are not infested with worm larvae in the first place.
