A review of the performance of these species is currently under way (by Liza White, 2009). It seems that at least two of the Bruchids are still widespread. (Lambdon, P. & Darlow, A. (2008) Botanical Survey of Ascension Island and St. Helena 2008. RSPB);

The bugs are perhaps now responsible for locally-intensive bursts of defoliation. (Lambdon, P. & Darlow, A. (2008) Botanical Survey of Ascension Island and St. Helena 2008. RSPB);
Three species of cowpea weevils (Bruchidae) were released to control Mexican thorn in the 1990s (Fowler, 1997), and these have apparently been supplemented by further specialist sap-feeding bugs, introduced accidentally.
