Abstract
Capnodis tenebrionis (L.) (Coleoptera Buprestidae) is an important and common insect pest of Rosaceae trees in several countries of the Mediterranean Basin. Infesrations on stone-fruit trees are often so severe as to totally destroy the orchards in consequence of larva! feeding on the roots. Egg laying occurs in summer on the trunk base or nearby in the soi!. A survey on the eclosion mode pointed out that neonate larvae, wherever eggs are laid, a!ways come into contact with the soi! environrnent, so justifying emomopathogenic nematode (EPN) application. The susceptibility of newly hatched larvae to EPN species was assessed in 2 laboratory bioassays by using multi-well tissue culture plates and cherry plum potted plants, respectively. Indigenous Southern Italian strains of Steinernema carpocapsae (Weiser) (ItS-MR7) and Heterorhabditis bacteriophora Poinar (ItH-CE1) were tested. Both species proved to be very effective in controlling C. tenebrionis larvae.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
