Diaprepes abbreviatus (Linnaeus) - (citrus root weevil)
The weevil is a polyphagous pest native to the Lesser Antilles of the Caribbean region, but has spread to Florida in 1964 where it has become a major pest of citrus and sugarcane. Other parts of the southern United States have been invaded more recently (Texas since 2000 and California since 2005). The adults feed on young leaves and lay their eggs between leaves tied together. Upon hatching, the neonate larvae fall to the ground, enter the soil and bore into the roots. Heavy infestations cause decline or death of citrus trees. Several other crops may be also attacked and the weevil has a wide host range in the Caribbean.

The larval stages last for about 1 year with around 10 instars. The use of biological control agents, especially entomopathogenic nematodes has been quite successful in some soil types. The adult weevil is bout 1 cm long with broad orange stripes on the elytra. The rest of the body is mainly black.
