The selectivity of entomopathogenic fungi to non-target organisms needs to be considered in Integrated Pest Management (IPM), because even though they are biological control agents, if used incorrectly, they can negatively alter the functioning of agroecosystems. Therefore, studies that assess the selectivity of these fungi to beneficial organisms are extremely important. The objective of this work was to evaluate the selectivity of Metarhizium anisopliae (Metarril®) and Beauveria bassiana (Boveril®) to adults of Telenomus podisi Ashmead (Hymenoptera: Scelionidae), under laboratory conditions. The products were evaluated on adult females of T. podisi, at the concentrations recommended by the manufacturer. To this, 0.2 mL of suspensions of each product and control (treatments) were applied to the inner surface of glass tubes, and then a female T. podisi was placed in it (≤ 48 h of emergence). After 24 h of contact, cards with 25 eggs of Euschistus heros Fabricius (Hemiptera: Pentatomidae) were offered for 24 h (COF24). After this period, the COF24 were withdrawn. After 72 h of contact of the female with the tube surface, new E. heros egg cards were made available (COF72) for 24 h for T. podisi ovipositioning. The mortality of T. podisi females was evaluated daily to determine longevity, percentage of parasitism and emergence, sex ratio, and egg-adult period of the T. podisi offspring. Metarril® and Boveril®, considered selective for adult females of T. podisi, did not negatively affect most of the parameters evaluated.
