Thesis subject

A hitch-hikers guide to egg parasitism

Minute hymenopteran wasps of the genus Trichogramma parasitise eggs of butterflies and moth. They are the most widely used biological control agents worldwide. However, their phylogeny, dispersal behavior, and parasitism capacities in nature are still understudied.

You will be collecting Trichogramma wasps emerging from eggs as well as hitchhiking on butterflies from different host species, host plants, and from different locations in the Netherlands. After you collected the ecological data, you will try to identify the species you collected by barcoding them. You can use the barcoding sequences (ITS2/ CO1) to also answer questions on their relatedness by making phylogenetic trees. Furthermore, you will test, whether closely related species are ecologically more similar than would be expected at random.
