Claim: In development,Tamarixia radiata nymph's body turns a dark brown and becomes "mummified"; the pupa extrudes cotton which adheres to the excavated host's body, the larvae pupates within the host and the adult wasp emerges and will parasiitise the host; within about eleven days.
Evidence: The nymph's body turns a dark brown colour and becomes "mummified". The T radiata pupa extrudes silk which is used to adhere the excavated host's body to the twig where the nymph was feeding and sometimes the silk can be seen around a nymph with a T. radiata pupa within The larvae then pupates within the remains of the host and the adult wasp emerges through a hole, visible to the naked eye, in the nymph's thorax or head. Under laboratory conditions, the development time from oviposition to the emergence of the adult from the host can take 11.4 days. The wasps will parasitise any age of host nymph but prefer the fifth instar nymphs.
