Metarhizium robertsii can be horizontally transmitted in Drosophila melanogaster as a result of mating. (a) A female Drosophila covered in Metarhizium conidia immediately after DTI, (b) growing hyphae of Metarhizium emerging from infected fly cadaver and (c) when kept in a cage with a Metarhizium-inoculated male, females that had been inseminated were much more likely to acquire conidia than those that remained infertile.
