Lisa Schwanz has a nice example in her 2008 paper entitled "Chronic parasitic infection alters reproductive output in deer mice."

Thanks Mercedes!

What about reproductive parasites increasing production of female progeny in arthropods?

This would be good Elena. Do you have a reference?

It is a large field and there is a lot of good reviews on this topic. However, I though you may like to take a look at the research paper showing the experimental results, for example:

Weeks AR, Stouthamer R: Increased fecundity associated with infection by a Cytophaga-like intracellular bacterium in the predatory mite, Metaseiulus occidentalis.

Proc R Soc Lond B 2003, 271:S193-S195

There you will find references to the reviews to get a more general picture.

Thank you. I will pick them.

Hi! I am also interested in this field. Most literature discuss parasitic manipulation in insects of medical and veterinary importance. I hope these references can help, I think they have some discussions on reproduction. All the best!

Thanks Justine!

This is a very interesting field indeed. While being relatively well studied in insects, much less is known about occurrence and functioning of such parasites in other arthropods and next to nothing in other animals. Looking at parallelisms would help a lot in understanding the phenomenon...

If we think like rigorous evolutionists than we should say, "yes, as long as the parasite benefits from the host's reproduction". For example, it might be transmitted by sexual contact or it could, like a retrovirus, even be incorporated into the host's genome.

Hi Alessandra,

Wolbachia (bacteria) interferes with the progeny outcome in insects (messes up the mendelian distribution of progeny). Can't remember how though (sorry). But I remember attending a seminar where it was being discussed using wolbachia infections to control parasitic diseases that are transmitted by female insects (so I think it might be biasing the progeny towards males?).

Don't know if this helps at all, but just thought of mentioning it. Good luck!
