Paternal trans-generational immune priming, whereby fathers provide immune
protection to offspring, has been demonstrated in the red flour beetle
Tribolium castaneum exposed to the insect pathogen Bacillus thuringiensis.
It is currently unclear how such protection is transferred, as in contrast
to mothers, fathers do not directly provide offspring with a large amount
of substances. In addition to sperm, male flour beetles transfer seminal
fluids in a spermatophore to females during copulation. Depending on
whether paternal trans-generational immune priming is mediated by sperm or
seminal fluids, it is expected to either affect only the genetic offspring
of a male, or also their step offspring that are sired by another male. We
therefore conducted a double-mating experiment and found that only the
genetic offspring of an immune primed male show enhanced survival upon
bacterial challenge, while phenoloxidase activity, an important insect
immune trait, and the expression of the immune receptor PGRP were
increased in all offspring. This indicates that information leading to
enhanced survival upon pathogen exposure is transferred via sperm, and
thus potentially constitutes an epigenetic effect, whereas substances
transferred with the seminal fluid could have an additional influence on
offspring immune traits and immunological alertness.
