Genetic 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 کاملAugmentation 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 کاملSteinernema feltiae Intraspecific Variability: Infection Dynamics and Sex-Ratio.
Entomopathogenic nematodes (EPNs) from the Heterorhabditidae and Steinernematidae families are well-known biocontrol agents against numerous insect pests. The infective juveniles (IJs) are naturally occurring in the soil and their success in locating and penetrating the host will be affected by extrinsic/intrinsic factors that modulate their foraging behavior. Characterizing key traits in the i...
متن کاملEscape of Steinernema feltiae from Alginate Capsules Containing Tomato Seeds.
The entomogenous nematode Steinernema feltiae was encapsulated in an alginate matrix containing a tomato seed. When these capsules were placed on 0.8% agar for 7 days, the seed germinated and ca. 20% of the nematodes escaped from the capsules, whereas only 0.1% escaped from capsules without seeds. When capsules containing nematodes and a seed were planted into sterilized or nonsterilized soil, ...

T h e e n tomo p a t hogen i c n e m a t o d e Steinernema feltiae is compat ible with many chemical pesticides including insecticides, mi t i c ides , fung ic ides , and h e r b i c i d e s (1,3,4,7,9,10). Cer ta in o rganophospha t e and carbamate pesticides, however , adversely affect S. feltiae (5,6). Removal or dilution o f the pesticides with water usually results in ne ma t o d e recover...
