Resumen:
Steinernema riobravis Cabanillas, Poinar & Raulston, 1994, Thermo
Trilogy strain (Nematoda, Steinernematidae) was the nematode species used for
application to small-scale field against Neocurtilla
claraziana (Saussure, 1874) (Orthoptera, Gryllotalpidae), a pest of soil in
three gardens of Gran La Plata,
Argentina. Assays were performed with dosages of 6,000, 10,000, 20,000, 40,000 and
80,000 nematodes per 3 m2,
with a density of 32 ± 7 mole crickets / 3 m2. The application was
performed with hand sprayer. The percentages of
effectiveness varied in different gardens, the first one lower dose was 65% ±
15.67 and the highest dose of 83% ± 22.25, with ± 80% to the average dose
18.56. For the second garden 50% ± 8.31 for the low dose and 76% ± 21.15 for
medium and higher, and for the third garden the lower dose was 42 ± 15.87%, the
highest dose of 66% ± 18.32 and the mean dose of 60 ± 17.92%. We observed in the
first three days post-treatment the highest percentages of infection for all
doses, on day 7 effectiveness for different doses significantly decreased
nearing the end of post-treatment (day 31) with 0% for the three trials. This study demonstrated the
potential of entomopathogenic nematodes as biological control agents, resulting
this introduced entomonemátodo an effective biological control agent for mole
crickets
