| Abstract | The use of the latex of Euphorbia splendens var. hislopii was considered as an effective control
method for Biomphalaria glabrata in Sumidouro, Rio de Janeiro. However, the appearance and expansion of the snail Melanoides tuberculata since August 1997, with the concomitant reduction of the population of B. glabrata suggest that competitive exclusion might be taking place. Depending on the susceptibility of the thiarid to the E. splendens toxin, the natural control that is occurring could be interrupted by the employment of the latex if the planorbid were less susceptible to the toxin. The aim of this
study is to investigate the molluscicidal activity of the latex on M. tuberculata. We used 420 M. tuberculata,
from Sumidouro. Fourteen different latex concentrations were tested using World Health Organization
general methodology. Probit analysis was used for LD90 and LD50 determination. The LD50 was 3.57
mg/l and LD90 was 6.22 mg/l. At the highest concentration (10 mg/l) there was no survival. No significant differences among replicas (χ2 = 8.31; gl = 13; p > 0.05) were found. The LD90 dose for M.
tuberculata was 13.8 times greater than that for B. glabrata, so that the molluscicide in the presence of
the thiarid may have a synergic effect on reduction of Biomphalaria populations. | pt_BR |
