Management Of Purple Loosestrife Lythrum

Chapter 4 – BIOLOGICAL CONTROL - Invasive

Galerucella spp. reduced above ground purple loosestrife biomass from 2,000g/m2 to less than 20g/m2 in 4 years (The Ontario Biological Control Program, 1998). Additional studies found that at high Galerucella densities (200 larvae/plant), plants were entirely stripped of all green tissue and seed production was prevented (Butterfield et al., 1996).
