The highly polyphagous Tetranychus urticae Koch is a key pest of Spanish clementine mandarins. This mite may be effortlessly found in clementine orchards, on the trees and also on the associated flora. In this chapter we discuss the suitability of a cover of the grass Festuca arundinacea Schreber (Poaceae) to enhance biological control of T. urticae relative to bare soil or a wild soil cover in citrus orchards. On the one hand, we hypothesize that the natural selection of a local strain of this… Expand
Patterns of ambulatory dispersal in Tetranychus urticae can be associated with host plant specialization
TLDR
The ambulatory dispersal of mites crawling up and down tree trunks in a clementine mandarin orchard grown in association with a F. arundinacea cover for one season provides evidence that host adaptation can hamper dispersal and establishment of the ground cover deme on trees, contributing to a better natural regulation of this pest species in citrus.

Effect of pollen of different plant species on the oviposition of two phytoseiid mites (Acari: Phytoseiidae) commonly found in citrus orchards in the Brazilian Amazonia
TLDR
Evaluating the effect of pollen of 13 plant species commonly found in Manaus region (Brazilian Amazonia) on the oviposition of Amblyseius aerialis and Iphiseiodes zuluagai, phytoseiid species abundant in citrus orchards in that region suggests that C. oleifera may play a role in maintaining predatory mite populations in such orchARDS. Expand
Plant-feeding may explain why the generalist predator Euseius stipulatus does better on less defended citrus plants but Tetranychus-specialists Neoseiulus californicus and Phytoseiulus persimilis do not
TLDR
The results demonstrate that pest regulation by specialist natural enemies may be more effective when prey feed on better defended plants, and E. stipulatus is a zoophytophagous mite, which can engage in direct plant feeding in sour orange and Cleopatra mandarin, whereas neither N. californicus nor P. persimilis do so. Expand
Can Plant Defence Mechanisms Provide New Approaches for the Sustainable Control of the Two-Spotted Spider Mite Tetranychus urticae?
TLDR
The use of VOCs and defence priming can be integrated into current management practices and reduce the damage caused by T. urticae in the field by implementing new, more sustainable crop management tools. Expand
Thus far but no further: predatory mites do not migrate effectively into strawberry plantations
TLDR
It is found that the diversity and densities of the predatory mites were enhanced somewhat by the management type of the field margins; especially the spontaneous vegetation favoured the presence of phytoseiids, however, despite the predatorymites being rather retained in the field margin also significant reduction in numbers of their prey T. urticae was recorded over the course of the year. Expand
Zoophytophagous mites can trigger plant-genotype specific defensive responses affecting potential prey beyond predation: the case of Euseius stipulatus and Tetranychus urticae in citrus.
TLDR
The observed responses could affect herbivore populations through plant-mediated effects and open opportunities for more sustainable and effective pest control methods (i.e., combining semiochemicals and biological control). Expand
When do predatory mites (Phytoseiidae) attack? Understanding their diel and seasonal predation patterns
TLDR
It is demonstrated that phytoseiids can exhibit diel and seasonal predatory patterns when feeding on Tetranychus urticae (Acari: TetrANYchidae) and should be taken into account when designing laboratory studies and also in field samplings, especially when applying molecular techniques to unveil trophic relationships. Expand
Tracking mite trophic interactions by multiplex PCR.
TLDR
The tracking of the trophic relationships within the citrus acarofauna, and the unveiling of the role of alternative food sources will pave the way for enhancing T. urticae biological control. Expand
Mite diversity (Acari: Tetranychidae, Tydeidae, Iolinidae, Phytoseiidae) and within-tree distribution in citrus orchards in southern Spain, with special reference to Eutetranychus orientalis
TLDR
Mite diversity of selected citrus orchards in Andalusia (southern Spain) was studied during 2002–2007 and the mites displayed a non-random distribution in the tree, and Eutetranychus orientalis preferred the outer and upper leaves. Expand
Molecular characterization of Cardinium, Rickettsia, Spiroplasma and Wolbachia in mite species from citrus orchards
TLDR
This work has determined the incidence of Cardinium, Rickettsia, Spiroplasma and Wolbachia as representatives of major distorter bacteria genera in Aplonobia histricina, Eutetranychus banksi, and T. urticae populations from Spanish citrus orchards. Expand

Does host adaptation of Tetranychus urticae populations in clementine orchards with a Festuca arundinacea cover contribute to a better natural regulation of this pest mite?
TLDR
Molecular genetic analyses with microsatellite markers support the conclusion that local adaptation of T. urticae found in the system may indeed contribute to a better natural regulation of this mite and indicate that sympatric deme × host combinations had higher mean fitness values than the allopatric combinations in clementine, but not in F. arundinacea. Expand
Effect of ground-cover management on spider mites and their phytoseiid natural enemies in clementine mandarin orchards (II): Top-down regulation mechanisms
TLDR
This work has studied the dynamics of both tetranychid and phytoseiid mites in four commercial clementine mandarin orchards under three different ground cover management strategies and hypothesize that both natural enemies and plant resources play important regulatory roles. Expand
Economic threshold for Tetranychus urticae (Acari: Tetranychidae) in clementine mandarins Citrus clementina
TLDR
The multivariate regressions highlighted the key role of phytoseiid mites and leaf flush patterns, which were negatively related to fruit damage, and the shortest sampling period that satisfactorily predicted fruit damage at harvest, extended from August to mid-October. Expand
Effect of pollen quality on the efficacy of two different life-style predatory mites against Tetranychus urticae in citrus
TLDR
Results suggest that pollen provision does not enhance the ability of these phytoseiids to reduce T. urticae populations, and poor quality pollen may prevent pollen feeders from reaching high numbers in the field. Expand
Genetic structure of a phytophagous mite species affected by crop practices: the case of Tetranychus urticae in clementine mandarins
TLDR
It is concluded that crop management has an impact on the population genetics of T. urticae which may be related to the alternation of some acaricides under IPM. Expand
Influence of selected fruit tree pollen on life history of Euseius stipulatus (Acari: Phytoseiidae)
TLDR
Results show that almond, plum, cherry and apricot pollen possess higher nutritional value for E. stipulatus than pear and apple pollen and thus may contribute in sustaining and increasing the predator population in field conditions. Expand
Effects of Euseius stipulatus on establishment and efficacy in spider mite suppression of Neoseiulus californicus and Phytoseiulus persimilis in clementine
TLDR
It is concluded that superiority of E. stipulatus in intraguild interactions may indeed contribute to the currently observed predator species composition and abundance, rendering natural control of T. urticae in Spanish clementine orchards unsatisfactory. Expand

Effect of ground cover management on Thysanoptera (thrips) in clementine mandarin orchards
TLDR
The results confirm the suitability of F. arundinacea as a cover crop for clementine mandarins and confirm that predatory mites could reduce populations of potential thrips and other citrus pests below economic injury level. Expand
