Scolytus is a genus of bark beetles (subfamily Scolytinae). It includes several species notorious for destroying trees in the forests. The Dutch elm disease is spread in North America by two species : the native elm bark beetle, Hylurgopinus rufipes, and the European elm bark beetle, Scolytus multistriatus. In Europe, while the aforementioned Scolytus multistriatus again acts as vector for infection, it is much less effective than the large elm bark beetle Scolytus scolytus.

Otiorhynchus (sometimes misspelled as Otiorrhynchus) is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil (O. sulcatus) and the strawberry root weevil (O. ovatus), are important pests, both as larvae and as adults. Larvae feed on plant roots. Adults are flightless with fused elytra and feed at night on plant foliage. In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual. Otiorhynchus weevils, particularly O. scaber, have been a popular

Sitona is a large genus of weevils in the family Curculionidae native to the Nearctic and Palaearctic regions. Over 100 species have been described.

It includes several species notorious for destroying trees in the forests of North America. The genus has a symbiotic relationship with many different yeasts, particularly those in the genera Candida and Pichia that aid in digestion and pheromone production. Various bacterial species also appear to be associated with larvae or adults of different species of Dendroctonus. For example, the bacterial species Rahnel

Eupholus is a genus of beetle in the family Curculionidae. The genus includes some of the most colourful of the weevils. The colour may serve as a warning to predators that they are distasteful. Most species feed upon yam leaves, some of which are toxic to other animals. The species occur in New Guinea and adjacent islands. This genus was described by French entomologist Jean-Baptiste Alphonse Dechauffour de Boisduval in 1835. thumb|150px|Eupholus bennetti
