Demonstrating the effectiveness of botanical extracts and essential oils on insect pests has become one of the alternatives to control methods. In this respect, botanical pesticides are a curicial resource but need to have minimal impact on natural enemies. The objective of this study is to assess the impact of Aronia melanocarpa leaf extract on the biological characteristics of different life stages of Trichogramma evanescens. Parasitized Ephestia kuehniella egg cards were immersed in A. melanocarpa leaf extract solutions (0.1%, 0.5% and 1%) and dH2O (control) for 5 seconds at 24 hours, 48 hours, 72 hours and 192 hours after parasitism, corresponding to the egg, larvae, prepupal and pupal stages of T. evanescens, respectively. The parasitization, emergence and sex ratio of T. evanescens were evaluated. The prepupal stage of parasitoit was more susceptable than other stages. Egg and pupal stages were more resistant than larvae and prepupal stages (Egg LC50: 0,772%, Pupa LC50: 0,412% respectively). This is the first study on the insecticidal effects of A. melanocarpa leaf extract on egg parasitoid T. evanescens. The leaf extract of A. melanocarpa completely at prevented adult emergence at a dose of 1% in the prepupal stage.
