Second-instar nymphs of the both aphid species were treated with fungal suspensions at concentrations of 106, 107, and 108 conidia/ml. Mortality was recorded on the 3rd, 6th, and 9th days, post-inoculation. Results demonstrated that mortality rates increased with higher conidial concentrations in both aphid species. In M. persicae, the highest mortality rate (95%) was observed at 108 conidia/ml after nine days. Similarly, A. fabae, exhibited 100% mortalityunder the same treatment conditions. The findings suggest that both conidial concentration and incubation period are key factors affecting the pathogenicity of L. Psalliotae, highlighting its potential as a promising biological control agent for aphid management.}, number={1}, publisher={Türkiye Biyolojik Mücadele Derneği}
