Notes: [Original title: Extension et régression d'une cochenille nuisible aux Graminées, introduite en Nouvelle-Calédonia, Heliococcus summervillei Brookes (Hemiptera, Pseudococcidae).] Heliococcus summervillei was detected in 1998 for the first time in New Caledonia. It was a very spectacular attack on grasses in pastures. In Australia, similar problems with H. summervillei were observed in 1926 on Pasaplum grass in a pasture. In New Caledonia, the phenomenon was studied from 1998 to 2003 on the main island, and the results are given here. Like in Australia, a natural reduction of populations was observed, so pronounced that the species is supposed to be extinct locally. The factors were not determined.
