Aphthona nigriscutis Foudras, 1860 |
Aphthona nigriscutis is a root-feeding flea beetle of the genus Aphthona . It is one of five Aphthona spp. that has been used in Alberta, Canada to control leafy spurge, an invasive plant that reduces pasture quality and degrades natural habitats. [1] It, along with A. lacertosa, is one of only two biocontrol agents thought to be effective against leafy spurge. [2]
Larvae cause the most damage to the plant by feeding on the roots. [2]
A. nigriscutis will feed on the native Euphorbia robusta Engelm, though this is thought to be acceptable as the weevil significantly reduces leafy spurge populations over time. [3]
A 14-year study documented a slight increase plant species richness in a Montana grassland system after release of A. nigriscutis to control leafy spurge. [4]
