Patogenicidade de isolados de Beauveria bassiana para ovos, larvas e ninfas ingurgitadas de Rhipicephalus sanguineus

Abstract: O presente trabalho objetivou avaliar a ação dos isolados JAB 07, CB 7 e AM 9 do fungo Beauveria bassiana para ovos, larvas e ninfas ingurgitadas de Rhipicephalus sanguineus. Padronizou-se a concentração de 109 conídios mL-1 para cada isolado e por meio de diluições seriadas, obtiveram-se as suspensões com concentrações de 10(8) e 10(7)con. mL-1. Preparou-se um bioensaio para cada fase do ciclo de vida do carrapato. Cada ensaio foi composto por 10 grupos tratamentos, formados por um isolado do fungo e uma conc… Show more

“…For the infection, a suspension prepared in a 0.1% (v/v) Tween 80 ® solution was used at the concentration of 10 8 con./ mL (13,14,15,16,18), obtained from young colonies of fungus (conidial viability: 97.6%). The R. sanguineus eggs were divided into 11 groups composed of 25 mg each, in glass tubes.…”

“…The concentration of 10 8 con./mL of B. bassiana and M. anisopliae caused the death of 95% of larvae of R. sanguineus 20 days after infection (14), and M. anisopliae applied at different tick stadiums caused high mortality rate in all unfed instars (20). B. bassiana caused a reduction in percent hatching of larvae derived from infected eggs and in percent ecdysis of larvae and nymphs of R. sanguineus (18).…”

“…microplus (12%) than in R. sanguineus (8%); (3) increased EHP (16.7 ± 0.3 days at 10 8 conidia ml -1 ) compared to treated (with 0.2% Tween 80 solution) and untreated controls (9.7 ± 0.1 and 9.6 ± 0.1 days, respectively). Prette et al (2005) B. bassiana and R. sanguineus (1) Decreased EH (12.1-0.7% at 10 7 -10 9 conidia ml -1 , respectively) compared to control (98.3-95.0%) at day 20 after treatment.

“…At least, garlic extract contains 33 sulfur compounds, several enzymes, 17 amino acids, and minerals such as selenium. Also, garlic plant has numerous biological activities that are attributed to its rich content of different volatile organosulfur compound (OSC) and other phytochemicals that work in synergically by combination of mechanisms for substance acting on various molecular targets [11][12][13][14].…”
