“…Nessa interação, espera-se que o inseticida atue como agente estressor na população praga e, consequentemente, o inseto alvo fique mais suscetível ao entomopatógeno. Kachot et al (2018) observaram que B. bassiana foi compatível com diferentes inseticidas testados em baixas concentrações, o que também foi observado nesse trabalho, onde uma menor dose do inseticida combinada ao fungo não interferiu na virulência do entomopatógeno, no entanto, ao misturar o fungo com 100% da dose de campo de cloridrato de cartape (Cartap 500 ® ) reduziu a virulência do fungo em 47%, indicando que nessa dose o inseticida é tóxico ao fungo.…”

“…One potential fungus in controlling several species of insect pests is Beauveria bassiana (Dannon et al, 2020). In several previous studies, the B. bassiana fungus was developed as a biological control agent against several ordoes such as Coleoptera, Lepidoptera, Hemiptera, and Orthoptera (Baron et al, 2019;Mahankuda & Bhatt, 2019). Larvae in these ordoes are important pests in rice cultivation and one of them is Scirpophaga innotata (Bayu et al, 2020).…”

White rice stem borer (Scirpophaga innotata) is one of the dangerous pests for rice (Oryzae sativa) because it attacks rice stems that can cause 50% loss of total production. The purpose of this study was to determine the pathogenicity of Entomopathogen Fungus Beauveria bassiana at different conidia dilutions (J), namely J1 (105), J2 (106), J3 (107), J4 (108), and J5 (109). The mortality of S. innotata larvae was tested with the density of B. bassiana of 2.08 × 106 conidia/ml. The effect of B. bassiana on the success transformation of S. innotata larvae to pupae for 14 observation day was also observed at the same B. bassiana density. This research resulted in the optimal pathogenicity of B. bassiana at dilution of 107 (treatment J3) which caused 100% death and 100% successful pupation. The lowest treatment was J5 (109 dilution) with a mortality rate of 50% and a successful pupation of 20%. The results of the probit analysis showed that the fastest average lethal time (LT50) value was found in treatment of 107 (J3) which reached 11.11 h. Keywords: Beauveria bassiana, Pathogenicity, Probit analysis, Scirpophaga innotata.
