Resumo(s)
The olive psyllid, Euphyllura olivina Costa is a very common olive pest in all the
Mediterranean countries. ln this paper results are reported of a preliminary study on the distribution and spatial pattern for immature stages of this species on the olive tree, as a basis to develop accurate and efficient sampling plans for populations estimation. The experimental work was carried out from Mareh lo July, 1999 lo 2002, in two groves located near Mirandela (north-east of Portugal) on olives of the Cobrançosa variety, unsprayed for several years and non-irrigated.
