Memo: influence of salicin in leaves on potential predators on these leaves.

The presence of salicin in willow leaves along with more complex  compounds that can be hydrolysed to it would be expected to influence  potential 

predators on these leaves. 

A number of studies have emphasised  the ecological effects of these compounds and have suggested that they do help determine the feeding 

preferences of such herbivores as the New  Zealand opossum, Arctic snowshoe hares, and a range of insects including  moths, butterflies, 

weevils, and sawflies. Most usually they act as  feeding deterrents although somme studies suggest more complex effects on  host-herbivore interactions. 

Thus salicin and populin appear to stimulate  the feeding of 2 beetles, Chrysomela vigintipunctata costella and  Plagiodera versicolora distincta. 

Chrysomelid beetles are believed to  hydrolyse salicin derivatives, oxidise the salicyl alcohol, 

and store or  secrete this as a deterrent aldehyde against ants and other arthropod  predators.
