Parasitoids may manipulate the behaviour of their host to help survive cold temperatures
During parasitoid development, the immature parasitoid is confined to the host and must therefore withstand the environmental conditions experienced by the aphid host. Interestingly, the study found that parasitized aphids displayed different behaviours to healthy aphids when exposed to unfavourable cold temperatures. It is possible that the parasitoid is manipulating aphid behaviour to avoid the unfavourable temperatures. Read more here.
