2018, Biological ControlCitation Excerpt :When newly discovered biocontrol organisms are repeatedly cultured in the laboratory or commercial settings they are subject to trait changes, including loss of beneficial traits (e.g., virulence, fecundity, environmental tolerance) (Hopper et al., 1993). Deterioration of beneficial traits has been observed in EPNs (Shapiro et al., 1996; Wang and Grewal, 2002; Bai et al., 2005; Bilgrami et al., 2006). Desirable traits in EPN strains, such as cold tolerance, that are displayed by locally-adapted isolates must be stabilized to avoid a loss in biocontrol efficacy at low temperatures.

2016, Biological ControlCitation Excerpt :Bai et al. (2005) suggested stabilizing beneficial traits in H. bacteriophora through the creation of genetically homozygous inbred lines that can deter beneficial trait decline. Other studies also suggested that selection relaxation results in a reduction in performance (Shapiro-Ilan et al., 1996; Anbesse et al., 2013a). Relaxation of selection pressure produced a decrease in host-finding among the selected S. feltiae populations (Gaugler and Campbell, 1989) and repeated sub-culturing also reduced the HSA of H. bacteriophora populations (Bilgrami et al., 2006).
