Trichoderma spp. are known for their non-pathogenic nature and their
ability to stimulate plant growth and defense mechanisms. By inducing systemic resistance,
they can render plants less susceptible to herbivores. Myzus persicae is
a highly important pest species that feeds on more than 200 plant species, including
pepper. In this study, the indirect effects of foliar-applied Trichoderma viride
on M. persicae were evaluated using age-stage, two-sex life table analysis
on the Avşar F1 kapya pepper cultivar. The results showed that the intrinsic rate
of increase (r), finite rate of increase
(λ), and population doubling time (DT) of M. persicae were significantly
affected by the foliar application of T. viride compared to the control.
The intrinsic rate of increase of aphids feeding on T. viride-foliar treated
plants was 0.3248 day⁻¹, whereas it was 0.3743 day⁻¹ in the control group, indicating
a significant reduction. Overall, the findings demonstrate that foliar application
of T. viride has a considerable negative effect on the biology of M. persicae
on the treated pepper plants compared to the control. Future studies involving different
application methods and pepper cultivars will help further clarify the underlying
mechanisms of these interactions.
