Field and laboratory studies were conducted to identify potential resistance among crape myrtles, Lagerstroemia spp., to Japanese beetle, Popillia japonica Newman and to flea beetles, Altica spp. Damage ratings revealed variation among cultivars in susceptibility to beetle feeding. Cultivars with Lagerstroemia fauriei Koehne in their parentage exhibited the least amount of damage in choice and ...

Pachybrachis holerorum n. sp. is described from the northern Apennines, Italy. The new species is related to P. karamani (Weise, 1893), from which it differs in the shape of the median lobe of the aedeagus and in small differences in chromatic pattern. The close relationship with P. karamani is confirmed by molecular analyses performed on a fragment of 829 nucleotides of the mitochondrial gene ...
