Water primrose: Biological control using co-evolved, host specific herbivores
A replicated, before-and-after field study conducted in 1994 in the USA (McGregor et al. 1996) found that introduction of flea beetles Lysathia ludoviciana to a pond significantly reduced the abundance of large-flower primrose-willow Ludwigia grandiflora. When the beetles were introduced to the pond, the abundance of large-flower primrose-willow declined from an initial average 61 g/m2 to an average of 7 g/m2 from July to September. Beetles were introduced in July into a one hectare pond containing the water primrose. The mean density of flea beetles varied throughout the study from 1-12/m2. Changes in abundance of large-flower primrose-willow was monitored in six enclosures measuring 5 x 10 m.
