Efficiency of different egg parasitoids and increased floral diversity for the biological control of noctuid pests

► We evaluated the efficiency of different egg parasitoids on Physalis peruviana pests. ► Trichogramma atopovirilia and Trichogramma pretiosum show high parasitism of two noctuid pests. ► We evaluated if floral resources affect the parasitism efficiency of T. atopovirilia. ► Red clover increases the longevity and parasitism rate of T. atopovirilia.
