What is the result when the parasitic wasp Lysiphlebus testaceipes targets an immature A. nerii?

The host aphid becomes a swollen, brown, papery casing called a mummy

One of the primary natural biological control agents specifically effective against the Oleander aphid is the parasitic wasp species, *Lysiphlebus testaceipes*. This wasp engages in specific reproductive behavior where the female wasp injects a single egg into a developing, immature aphid. Once inside, the wasp larva consumes the host's internal tissues as it develops. This internal consumption leads to a distinct physical transformation of the host aphid: its body swells significantly and ultimately hardens into a characteristic brown, papery structure. This modified, dead aphid casing is universally referred to as a mummy, signaling that the aphid has been successfully parasitized and is no longer a viable threat or reproducer.
