| Descripción: | Introduction. Anthonomus eugenii causes considerable economic losses in sweet pepper (Capsicum annuum). Chemical control is ineffective; therefore, it is essential to explore other management alternatives. Objective. Determine the potential of Beauveria spp. strains for the biological control of Anthonomus eugenii in sweet pepper under greenhouse conditions. Materials and methods. The research was conducted between May and august 2023 at the Fabio Baudrit Moreno Experimental Station in Alajuela, Costa Rica, in a 96 m2 multispan greenhouse. The evaluated treatments were INTA H-140, INTA H-149, INTA H-168, and INTA H-181, along with an absolute control, using a completely randomized design (CRD) with three replications. The number of live adults and infested peppers were quantified weekly. Pearson correlation analysis and repeated measures ANOVA were performed for the evaluated variables. Results. There was interaction between treatments and evaluation date for the number of adults (p < 0,05). INTA H-168 strain significantly reduced the Anthonomus eugenii population in 60 ddt and 64 ddt evaluations, with differences of 22,96 and 47,15 adults, respectively. For the variable of the number of infested peppers, there was only an individual effect by ddt (p < 0,05). Additionally, a positive correlation was found between the average number of infested peppers and the number of live adults for the 64 ddt and 73 ddt (p < 0,05). Conclusion. The significant reduction in live adults in the first two evaluations of INTA H-168 strain and its parasitism evidence biological potential for the control of Anthonomus eugenii. |
