Augmentation Biological Control Using the Entomopathogenic Nematode Steinernema Feltiae against the South American Leafminer Liriomyza Huidobrensis
Routine measures used to control the larval stages of non-statutory leafminer species in the United Kingdom rely largely on either the use of the braconid parasitoid Dacnusa sibirica Telenga and the eulophid wasp Diglyphus isaea Walker as, for example, in tomato crops, or on chemical insecticides for control in leafy salad and ornamental plants (Garthwaite and Thomas, 2001). The availability of...
متن کاملDynamics of the Entomogenous Nematode Steinernema feltiae Applied to Soil with and without Nematicide Treatment.
The dynamics of Steinernema feltiae strain DD-136 in soils with different fauna was investigated to determine the best method for the biological control of soil insects. Infective juveniles (J3) were applied to field plots with and without 1,3-D (Telone II) fumigation. Recovery of J3 and changes in native nematode fauna were monitored until the applied J3 were no longer recovered by Baermann fu...
متن کاملInfection of the Entomopathogenic Nematode, Steinernema carpocapsae, as Affected by the Presence of Steinernema glaseri.
The infection behavior of Steinernema carpocapsae infective juveniles (IJ) was investigated in the presence and absence of S. glaseri. Mixed inoculation of S. carpocapsae with S. glaseri IJ significantly raised the nictation rates of S. carpocapsae IJ. Significantly more S. carpocapsae IJ migrated to the host insect in the mixed inoculation with S. glaseri IJ on agar plates. More S. carpocapsae...
متن کاملGenetic Variability among Strains of the Entomopathogenic Nematode Steinernema feltiae.
A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and host-finding ability. All of the strains assayed showed both low ultraviolet tolerance and poor host-finding ability, indicating that the likelihood of improving these traits through more extensive popu...
متن کاملFoliar applied entomopathogenic nematodes Steinernema feltiae are not suitable for controlling Thrips tabaci in leek
Two field trials in leek were set up to determine and, if possible, improve the effect of spray applications of Steinernema feltiae (Filipjev) Wouts, Mracek, Gerdin et Bedding against Thrips tabaci Lindeman. The first trial focused on selecting a suitable application technique and on testing the effect of an attractant on thrips control in leek. The second trial focused on incorporating entomop...
