Three strains of Trichoderma harzianum and one strain of Trichoderma citrinoviride were sprayed on insect adults and Phaseolus vulgaris L. beans in order to investigate the efficiency of the fungi in combating Acanthoscelides obtectus insect pest. The strains E20, T34, and T019 exhibited high virulence on adults. Spores of T34 isolate were more attractant for both sexes and showed a higher mortality rate on insects in contact with treated beans than the other strains. Treated beans showed a lower weight loss compared to the untreated ones. T019 and T008 treatments resulted in a lower weight loss of beans than the other fungal strains. Daily insect emergence was reduced in treated beans. The strain T34 accounted for the lowest daily emergence of insects. T008, T019, and E20 exhibited the capacity to repel insects, which resulted in a reduction of damaged beans as well as a lower number of holes per bean. Trichoderma strains were reisolated from insects’ cadavers extracted from treated beans. Regarding these results, T34 strain could be used in the control of A. obtectus adults due to its high lethal effect. Additionally, T008 and T019 strains, showing good results in terms of insecticidal activity, insect repellency, reduction of damaged beans and lower weight loss of beans, could also be used for the biological control of A. obtectus.SIThis research was funded by the Ministry of Science, Innovation and Universities (Spain) (Resolution of July 27, 2018, BOE No.184, of July 31), through to the grant awarded to Alvaro Rodríguez Gonz alez (PTA2017e14403-I) in their program Technical Support Staff, by the Education Department of the Junta de Castilla y Le on for the project entitled “Aplicaci on de cepas de Trichoderma en la producci on sostenible de judía de calidad (Reference: LE251P18)”, and by the Ministry of Science, Innovation and Universities for the grant entitled “Aislamiento de cepas de Trichoderma productoras de trichotecenos a partir de cultivos de judía y estudio de su efecto en la defensa de la planta frente a enfermedades fúngicas (RTI2018- 099600-B-100).
