European parasitoids of Lilioceris lilii (Coleoptera: Chrysomelidae).
Collections of eggs, larvae and adults of the lily leaf beetle (Lilioceris lilii) were made in France from 22 to 29 May 1996, near Saint-Malo, Angers, Bordeaux, Toulouse and Montpellier. During the last week of May 1997 and 1998, collections were made within 20 km of Angers in 11 home gardens and in the lily fields of 7 small commercial lily bulb growers. In 1998, collections were made in a garden in Blotzheim, France, and in northwestern Switzerland. Adults, larvae and eggs were collected on cultivated lilies in Delémont between 19 July and 2 September, and on wild lilies (Lilium martagon) in the Jura mountains near Grenchen from 22 June to 21 July and at Weissenstein on 5 July 1998. Rearing and dissection experiments showed that no parasitoids of adults or eggs of Lilioceris lilii were found at any site. On the other hand, 4 larval parasitoids from the 1996 to 1998 collections were identified: Tetrastichus setifer, Lemophagus errabundus, Lemophagus pulcher and Diaparsis jucunda.
