The compatibility of infective juveniles (IJs) of the entomopathogenic nematode, Steinernema feltiae, the parasitic wasps Diglyphus isaea and Dacnusa sibirica, and chemical insecticides to control larval stages of the South American leafminer, Liriomyza huidobrensis, on leafy salad crops was investigated. In intact leaf mines, leafminer larvae already parasitized by D. isaea which had developed to the larval or pupal stage, and D. sibirica in the larval stage were subsequently also infected by S. feltiae following a foliar application. This reduced the potential of the wasps to survive until the adult stage. In similar tests foliar applied chemical insecticides reduced the survival to adulthood of D. sibirica and their host larvae. However, a soil drench of imidaclorpid did not cause a significant reduction in the number of D. sibirica which survived the treatment and developed to adult emergence. Tests to investigate the utilisation of parasitoids following foliar applications of nematodes found that adult D. isaea did not discriminate between the healthy and nematode-infected leafminer larvae for host feeding, although 98% of eggs laid by the female wasps were deposited alongside healthy larvae. |
