The recommended practice for infesta-
tions of apple rust mite is pre-blossom treat-
ment with paraffin oil and/or summer spray-
ing with acaricides (Papaioanou-Soulioti,
2001). No threshold limit is established in
Greece for
A. schlechtendali
. Ontario Minis-
try of Agriculture, Food and Rural Affairs re-
ports a threshold on apple rust mite pop-
ulation, which is 200-500 mites per leaf
(Solymar and Walker, 2011). In lower popu-
lation, application must be avoided because
the apple rust mite provides valuable prey
for predatory mites.
In citrus groves in Greece,
A. pelekas-
si
and
A. sheldoni
may develop high popu-
lations when weather conditions are favor-
able. In the case of high infestation of
A.
pelekassi
and
A. sheldoni
in
citrus orchards,
selective acaricides should be applied
against
A. pelekassi
in summer (beginning of
June) and autumn (mid-September to mid-
November) and against
A. sheldoni
in spring
and at the beginning of June (Papaioannou-
Souliotis, 1985).
In olive groves when outbreaks of erio-
phyoids occur under favorable weather con-
ditions, two applications with sulfur or par-
affin oil are recommended, the first early in
spring before flowering and the second 10-
15 days later (Broumas and Katsoyiannos,
2009).
In grapevine, it is well demonstrated
that sulfur sprayings applied early in the
spring can control mite populations e.g.
sulfur sprayings applied at the onset of the
