Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant...

Hyperaccumulated elements such as Ni may defend plants against some natural enemies whereas other enemies may circumvent this defense. The Ni hyperaccumulator Berkheya coddii Roessler (Asteraceae) is a host plant species for Chrysolina clathrata (Clark), which suffers no apparent harm by consuming its leaf tissue. Beetle specimens collected from B. coddii had a whole body Ni concentration of 26...

The species of the subgenus Stichoptera occurring in Switzerland are revised, based on a combination literature data, old museum specimens and recent material. Four species, one with two subspecies, Chrysolina kuesteri (Helliesen, 1912), Ch. latecincta (Demaison, 1896), norica (Holdhaus, 1914), rossia (Illiger, 1802) sanguinolenta (Linnaeus, 1758) confirmed to occur Switzerland, while gypsophil...
