Abstract:Pseudelatia separata(Lepidoptera:Noctuidae)infected with Pseudelatia separata NPV
(asNPV)and Pseudelatia separata GV (PsGV)and coinfected with the two viruses,the structural
characters of its pi0thoracic gland( rG)and the ultrastructure of the gland cells were observed.The
results showed that pathological chan ges appeared in the infected PTGs.In P lV infected treatment,
the color of the glan d was purple—black dyed with eosin an d the cells were distorted ly squeezed together.
The tracheae nearby showed grievous pathological chan ges an d a lot of white granules deposited around
it.The pathological chan ges in PsGV infected treatm ent showed an other pattern.The glan d body was
relative small with smaller individual cells,most of which were red dyed with eosin.The cell limits
were obscure.In coinfected treatment.there were few glan d cells colorated by esoin.The ultrastructure
observ ation also showed some pathological chan ges in the glan d cells
