Abstract

Farinocystis tribolii Weiser-infected larvae of Tribolium castaneum (Herbst) had significantly lower amounts of protein. The diseased larvae had lower total free aminoacids content when compared to uninfected larvae. The DNA levels were enhanced due to infection, whereas RNA levels did not vary significantly. Total lipids were depleted in diseased larvae, but the free fatty acids were more in diseased than in healthy larvae.

The reduction in the levels of protein, free aminoacids and lipids in diseased larvae is primarily due to the destruction and depletion of the fat bodies by the sporozoans. The increased levels of DNA and free fatty acids in infected insects could have been contributed by the parasites themselves.
