Abstract
The study aimed to determine the effectivity of LD.2016 and M6-4 isolates of entomopathogen Beauveria bassiana on Myzus persicae Sulzer (Hemiptera: Aphididae). In this context, the doses of 106, 107 and 108 conidia mL-1 for isolates were used. Experiments for each dose and a control group were set up to be 50 repeats. As a result of the analysis, the rm values of the individuals exposed to 106, 107 and 108 conidia mL-1 doses were calculated as 0.340, 0.352 and 0.337 females/female/day, respectively for the LD.2016 isolate, and 0.292, 0.263 and 0.268 females/female/day, respectively for the M6-4 isolate. The value was 0.280 females/female/day for the control group. By increased dose, the values of lx and mx parameters were decreased, too. Besides, the Weibull and Enkegaard models were applied on the lx and mx values of the populations exposed to entomopathogen isolates. Consequently, it is thought that the isolates of entomopathogen B. bassiana, less harmful to humans and the environment, can be used as a biological control agent in an integrated pest management program for the controlling of the pest.

The study aimed to determine the effectivity of LD.2016 and M6-4 isolates of entomopathogen Beauveria bassiana on Myzus persicae Sulzer (Hemiptera: Aphididae)
It was determined that all M. persicae individuals exposed to conidia mL-1 dose of M6-4 isolate were died on the 33rd day, and all individuals in the both groups, exposed to and conidia mL-1 doses, were died on the 19th day (Figure 2)
The statistical analysis applied to the obtained data demonstrated that net reproductive rate (R0), the mean generation time (T0), finite rate of increase (λ) and gross reproduction rate (GRR) values decreased with increasing concentration
Summary
The study aimed to determine the effectivity of LD.2016 and M6-4 isolates of entomopathogen Beauveria bassiana on Myzus persicae Sulzer (Hemiptera: Aphididae). In this context, the doses of 106, 107 and 108 conidia mL-1 for isolates were used. It is thought that the isolates of entomopathogen B. bassiana, less harmful to humans and the environment, can be used as a biological control agent in an integrated pest management program for the controlling of the pest. Individuals of M. persicae become harmful by sucking plant saps and secrete toxic substances into the plant during the absorption They cause fumagine (dark-colored sooty mold) by secreting honeydew. It was determined that B. bassiana and M. anisophile isolates, which were commercially produced in the management of herbivore
