Abstract Gonipterus scutellatus (Coleoptera:
Curculionidae) is a pest of eucalyptus in Chile. Susceptibility of Eucalyptus
camaldulensis, E. globulus ssp. globulus, and E.
robusta to larval feeding were studied by determining foliar area
loss. The effect of feeding on larval protein profiles was analysed by
electrophoresis. E. camaldulensis was more susceptible (11.21%
foliar area consumed) than E. globulus (6.47%) and E.
robusta (3.62%). Nineteen proteins were common in larvae fed the
three kinds of food, whereas 11 exhibited variations (marker proteins).
As all larvae came from E. globulus providing the same
nutrition, relatively few (20) proteins were detected in them. More
proteins (30) were found in larvae feeding on E. robusta. The
greatest number of marker proteins occurred in E. robusta (11),
followed by E. camaldulensis (9), and E. globulus (1).
Thus, larvae fed on three eucalyptus species had three different
protein profiles.
