showed that rove beetles (Coleoptera: Staphylinidae) were the most abundant-active
group representing about 38.6% of the total number of predators collected, followed
by spiders (Arachnida: Araneae) (28.9%), earwigs (Dermaptera) (18.0%), ground
beetles (Coleoptera: Carabidae) (12.7%) and tiger beetles (Coleoptera: Cicindelidae)
(1.8%). A recent study (Monzó, Urbaneja, Sabater-Muñoz, Castañera, 2007; Monzó,
Mollá, Castañera, & Urbaneja, 2009) indicates that the wolf spider Pardosa cribata
Simon (Araneae: Lycosidae), the most abundant ground-dwelling spider in the
Valencian citrus orchards, could play an important role in controlling those pests.
CONCLUSIONS
Biological control has been and will definitively be an increasingly important part of
citrus crop protection practices. Because of the present European limitations on the
importation of exotic IBCAs, straightforward protocols to evaluate candidate species
are urgently needed. Simultaneously, studies focused on the role of indigenous
IBCAs in the citrus agrosystem and the conservation of both native and naturalized
natural enemies, have to be emphasized. Augmentative and conservation BC will
probably play a gradually more important function in the Spanish citrus industry and
the first changes are already happening.
