Other Common Names
Saltcedar Leaf Beetle (1); Tamarisk Beetle
Synonyms and other taxonomic changes
A complex of five fully diagnosable species of tamarisk beetles was established by Tracy and Robbins (2009)(2) as forming the D. elongata species group: D. elongata, D. carinata, D. sublineata, D. carinulata and D. meridionalis
Explanation of Names
Diorhabda Weise 1883
Numbers
4 spp. of tamarisk beetles (excluding D. meridionalis) were intentionally introduced (starting in 2004) for biological control of tamarisk in the western United States. (2)
Range
Introduced in sw./w. US(3)(1)
Members of the complex are native to drier regions of the Palaearctic(2), from the Mediterranean, through central Asia to w. China. [NB: "w. China & e. Kazakhstan" range cited for species D. elongata sensu stricto in(1) is erroneous. That species is mediterranean...D. carinulata is the species whose range includes w. China & e. Kazakhstan(2)).
Food
Larvae and adults feed exclusively on species of saltcedar (genus Tamarix).
Remarks
Introduced to control highly invasive non-native shrubs of the genus Tamarix(3).
