“…Fungi were grown on Sabouraud dextrose agar, enriched with yeast extract (1%) and 500 ppm of the antibiotic chloramphenicol; they were incubated for a period of 21 days at 25 8C and a 12 h light -12 d dark photoperiod. For mass production, the fungi obtained were grown on rice grains (Prior and Jollands, 1988). Once the conidia were obtained, they were dried for 8 days in a hood at 25 8C and a relative humidity (RH) of 53%, and then stored at 5 8C until their use in the field.…”

“…Formulações à base de óleo, além de aumentar a sobrevivência dos conídios, auxiliam sua adesão ao tegumento do inseto, protegendo-os contra a dissecação e os raios ultravioleta, facilitando também o manuseio para o aplicador. O óleo auxilia na adesão dos conídios nas superfícies hidrofóbicas da cutícula dos insetos e das plantas (PRIOR et al, 1988;GOETTEL, 1993).…”

ResumoHedypathes betulinus (KLUG, 1825) (Coleoptera: Cerambycidae) é a principal praga da cultura da ervamate. Para o seu controle, avaliou-se em laboratório e campo a utilização de fungos entomopatogênicos. Em laboratório, foi avaliada a infectividade de isolados dos fungos Beauveria bassiana (Bals.) Vuillemin, 1912; B. brongniartii (Sacc.) conídios/mL, variando de 6x10 5 a 5x10 6 conídios/mL. Foi avaliada a persistência do isolado CG 716 de B. bassiana formulado à base de óleo emulsionável em campo, verificando-se alta mortalidade nas primeiras três semanas após a aplicação do fungo, variando de 95 a 78%, decaindo para 65 a 47%, um e dois meses após a aplicação, respectivamente.

Abstract Entomopathogenic fungi in the control of Hedypathes betulinus and evaluation of persistence.Hedypathes betulinus (KLUG, 1825) (Coleoptera: Cerambycidae) is the main pest of "erva-mate" (Ilex paraguariensis) culture. Focusing its control, it was evaluated in laboratory and field the entomopathogenic fungi using. In laboratory, it was evaluated the infectiveness of the strains of the following fungi: Beauveria bassiana (Bals.) Vuillemin, B. brongniartii (Sacc.) Petch, Metarhizium anisopliae (Metsch.), Sorokin and Paecilomyces (= Isaria) sp. Bainier, in adults specimen of H. betulinus. The insects were immersed in a conidial suspension at a concentration of 10 7 conidia mL -1 . After the application the insects had been kept at laboratory for mortality register. It was verified that B. bassiana (CG 716) was more infective, reaching to 100% of mortality. It estimated LC 50 of isolated CG 716 of B. bassiana with five concentrations and a variation of l0 5 to l0 9 conidia mL -1, along the control plot. The estimated LC 50 was 2,0 x 10 6 conidia mL -1 , ranging from 6 x 10 5 to 5 x 10 6 conidia mL -1. The persistence of strain CG 716 of B. bassiana -formulate oil was evaluated in field, producing the highest mortality, at the first three weeks after the application of the fungus, with a variance of 95 to 78 %, with a decreasing of 65 to 47% , along one and two months after the application , respectively.
