A Parasitoid of Aphids Manipulates Host Mummification Site, With Effects on Survival but Not Hyperparasitism. [PDF]

open access: yesEcol Evol
Parasitoid wasps can manipulate host behavior to enhance their own survival. Here we find that a parasitoid of aphids, Aphelinus chaonia, induces aphids to move to the leaf axil or leave the plant prior to pupation. This seems to have no effect on hyperparasitism, but mummy location may nevertheless impact parasitoid survival.
