Interestingly, numerous bacteria belonging to the genera Klebsiella were found when larvae were fed on barley but were absent in larvae from the artificial feed or only found in very low representation in lima bean-fed insects, which could indicate an important role for species of this genera in larva feeding on grass species, as was seen in our study on sugarcane.

This deficiency is reflected in the very low representation of East African populations in global HLA databases [51].

On the other hand, this result may allow us to efficiently prefilter and render environment maps in computer graphics, since only a very low frequency representation of the environment need be used.
