of viral inoculation on diet choice. Diet blocks, each weighing
between 07 and 13 g, were replaced daily until the larvae had
ceased feeding at the pre-pupal stage. Uneaten food was dried to a
constant mass in a desiccating oven. Consumption was calculated
as the difference between the initial and final dry weight of each
diet block. The initial dry weight of the blocks was estimated using
regression of control blocks for each diet type (Lee et al. 2006).
From the dry mass of food eaten, the amount of protein and carbohydrate
consumed on each day was estimated. Deaths were
monitored daily until all larvae had died or pupated; viral infection
was confirmed by the presence of OBs.
