Behavioural response to an unsuitable host plant in the gypsy moth (Lymantria dispar L.)
Languages of publication
To assess local differentiation in host preference, a two-choice test was performed on firstinstar gypsy moth larvae originating from an oak and locust-tree forest. More than 40 generations feeding on locust-tree leaves, rich in alkaloids, led to non-efficient discrimination of host leaves in larvae from a locust-tree forest. Possible causes of observed population differences are discussed in the present paper.
