Abstract:

Four species of entomopathogenic nematodes, Steinernema carpocapsae, Heterorhabditis bacteriophora, H. indica and H. marelatus, were tested for their ability to kill and reproduce in larvae of the Asian longhorn beetle, Anoplophora glabripennis (Motchulsky). The larvae were permissive to all four species but mortality was higher and production of infective juveniles was greater for S. carpocapsae and H. marelatus. The lethal dosage of H. marelatus was determined to be 19 infective juveniles for second and third instar larvae and 347 infective juveniles for fourth and fifth instar larvae. H. marelatus infective juveniles, applied via sponges to oviposition sites on cut logs, located and killed host larvae within 30 cm galleries and reproduced successfully in several of the larvae.
