Diaprepes abbreviatus (Linnaeus 1758)
10-19 mm
color highly variable (from gray to yellow to orange to black)
Native to the Caribbean, adventive and established in so. US: so. & central FL (1964), so. TX (Cameron & Hidalgo Cos 2000, Corpus Christi 2005, Houston 2009; map), so. CA (2005), LA (2008); further north in greenhouses
highly polyphagous; larvae feed on roots, adults on foliage of citrus trees (esp. oranges in TX) and almost 300 other plant species(1)
Major pest of citrus crops: larvae often girdle the taproot, which may kill the plant and provide an avenue for Phythophora infections. A single larva can kill young hosts while several larvae can cause serious decline of older, established hosts.
Pest of sugarcane in the Caribbean(2); earliest record in our area: FL 1964(1)
