چکیده انگلیسی
Adoxophyes orana granulovirus (AdorGV) was isolated from overwintering larvae in an orchard in Kent, in the UK. The developmental time of each A. orana instar was determined by measuring the size of the head capsule. The susceptibility of the larvae to the English isolate of AdorGV was evaluated in laboratory bioassays using inoculation by microdroplet feeding and applied dose assays. A series of bioassays were performed to determine LD50 and ST50 values for first, fourth and fifth instar larvae. The median lethal doses ranged from 30 occlusion bodies in first instar to 1.36Â ÃÂ 106 in fifth instar. The median survival time decreased the later the larvae were infected and ranged from 37Â days in first instar to 24Â days in fifth instar. Approximately half of the infected larvae released a discharge rich in occlusion bodies from their posterior end prior to death. Approximately 85% of larvae attempted pupation and died as larva-pupa intermediates.
