Resumo(s)
Jasmine moth population was monitored
in olive groves in Cova da Beira, using traps
baited with three commercial formulations
of pheromone: Russell (in tricoloured funnel
traps), SEDQ and Suterra (both in delta
traps). Counts were carried out weekly from
March to November 2010 for SEDQ’s pheromone
and from September to November
for Russell’s and Suterra´s pheromones. The
scouts ranged among 0 and 4 insects/trap/
week. A contaminant Lepidoptera species,
not yet identified, was captured in the SEDQ
traps. They were smaller, brownish and they
were captured largely than the jasmine moth.
Comparing these flight curves to the ones
obtained from Castelo Branco, Ribatejo and
Alentejo Stations (official Advisory Services),
regions where this pest was monitored
using the same methodology, a great disparity
in the number of individuals captured was
observed, which raises the possibility of the contamination found here may also occur in
some of these regions
