“…Jung and Croft (2001a) reported that ambulatory dispersal was essentially used by females, and that larvae were the less dispersive stage. However, Sahraoui et al (2016) showed no difference in sex-ratio and the immature/adult ratio of mites dispersing along citrus trunks. Jung and Croft (2001a) reported a walking speed ranging from 0.1 to 0.4 mm/s for N. fallacis (2.7 h to move through 1 m).…”

“…Aerial dispersal ability seems to depend on the species considered. In aerial traps located under citrus trees canopy, E. stipulatus was not captured (Sahraoui et al, 2016). Tixier et al (1998Tixier et al ( , 2000 showed that males, females, and immature stages of K. aberrans dispersed in the same way, whereas Jung and Croft (2001a) reported that the female was the main dispersal stage for N. fallacis.…”

“…In a framework of conservation biological control, it is important to assess why dispersal occurs, for enhancing movements between agroecosystem components. Most studies dealing with dispersal were based on the use of traps in field conditions (i.e., Tixier et al, 1998Tixier et al, , 2000Tixier et al, , 2006Mailloux et al, 2010;Aguilar-Fenollosa et al, 2011a,b, 2012Liguori et al, 2011;Sahraoui et al, 2012Sahraoui et al, , 2016, or on the assessment of dispersal behavior (i.e., distance traveled from a release point) in lab conditions. Only one genetic population study was carried out on the dispersal of Neoseiulus womersleyi (Schicha) between tea orchards and between this crop and the non-crop plant, Tithonia rotundifolia Torch, in Japan (Hinomoto et al, 2011) (see below).…”

“…However, they also noted the importance to manage the ratio of T. urticae/predatory mites on cover plants, to avoid T. urticae infestation in vineyards. Sahraoui et al (2016) showed that some plant species within citrus orchards are an important reservoir for E. stipulatus (Amarantus retroflexus L., Chenopodium murale L.) the main predatory mite found on the trees. They attributed the presence of I. phiseius degenerans (Berlese) in one part of an orchard on citrus trees to the occurrence of this species, in great densities, on Solanum nigrum L. Even though no global impact of ground cover management was observed on predatory mite diversity and densities on trees, they noted the lowest densities on trees when weeds were chemically controlled.…”

Phytoseiidae mites are efficient predators, able to control pest mites and small arthropods in crops all over the world, using three biological control strategies: (i) augmentation, (ii) classical, and (iii) conservation. This paper focuses on the latter strategy. Most of those predatory mite species are generalist predators; they are naturally present in agro-ecosystems both on crops and adjacent natural vegetation. Because of such characteristics, their occurrence is usually associated with the use of fewer pesticides, providing relief to ecosystem services. As a first baseline for managing their occurrence in agro-ecosystems, a review of the present knowledge of plants and predatory mite interactions and predator dispersal ability is proposed. In addition, based on the author's own occurrence database, the study aims at analyzing (i) plant traits and the potential co-evolutionary relationships between plants and predatory mite species and (ii) how this can be used to forecast favorable plants to key predatory mites. For this, some examples were taken, i.e., vine and citrus crops, and three species, Kampimodromus aberrans, Euseius stipulates, and Typhlodromus (Typhlodromus) pyri. The main conclusion is that the occurrence database can help in determining the probability of finding predatory mite species on crops and non-crop plants. However, because some elements are lacking, especially predatory mite density, plant traits and the true overall distribution, it is currently, difficult to associate plant traits and plant phylogeny to Phytoseiidae diversity. Additional meta-analyses in collaboration with plant specialists would be required. Finally, the paper presents some examples of agroecosystem management at different scales (intercropping, agroforestry, borders management, landscape).

The abundance and diversity of eriophyid and phytoseiid mites in south and central Florida were assessed in six citrus orchards under three different pest management systems, conventional, organic, and untreated. Tree canopy, ground cover, and leaf litter were sampled every two months in two groves each under conventional, organic, and untreated pest management from April 2019 to February 2021. The citrus rust mite, Phyllocoptruta oleivora (Ashmead) was identified from 95-99% of the samples from study groves except 45% in one untreated orchard (n = 938). The pink citrus rust mite, Aculops pelekassi (Keifer) was present in organic and untreated orchards at 5% and 28%, respectively, but absent from conventional orchards (n = 134). Twenty-nine species of phytoseiid mites were identified from 1,778 specimens. Thirteen species were present in the canopy, fifteen in the ground cover, and eighteen in the leaf litter with some common species among these habitats. In the tree canopy, Typhlodromalus peregrinus (39%), Euseius spp. (25%), and Iphiseiodes quadripilis (19%) were the dominant species.Typhlodromalus peregrinus (43%), Typhlodromips dentilis (25%), and Proprioseiopsis mexicanus (13%) were the major species in the ground cover. Species richness was lower in organic orchards (3.0) compared to conventional and untreated orchards (5.0 and 4.7, respectively). In the leaf litter, Amblyseius curiosus (26%), Proprioseiopsis carolinianus (15%), Chelaseius floridanus (14%), and A. tamatavensis (12%) were the most common species.Shannon index was significantly higher in conventional orchards (1.45) compared to organic and untreated orchards (1.02 and 1.05, respectively). Evenness was also higher in conventional orchards (0.86) compared to organic and untreated (0.72 and 0.68, respectively). Finding of several phytoseiids in abundance across pest management programs suggest the need for identifying their role in pest suppression particularly mites.

Phytoseiidae mites suppress pest mites and small arthropods below injury levels. A study on cohort life stage of Amblydromalus hum Pritchard & Baker was carried out to determine development and growth of the Phytosiidae mite. General observation showed a lower turnover of the larval stage to the Protonymph stage from the 12 th day onward, probably this could be attributed to some cannibalism taking place where adults could prey on the larvae and the nymphal stages. Significantly, the larvae were most abundant within 21 days when A. hum was fed E. africanus showing a cohort life stage composition of 39% overall population among other motile life stages. Similarly, same larvae appeared significantly most abundant when feed on maize pollen at 61% over other cohort life stage within a period of 4 days. Female adults starved death by 3 rd day and were found not to lay eggs within the period. It was observed that female adult A. hum did not live beyond the 3 rd day when 100% mortalities occurred where maize. The study results showed that A. hum preference for E, africanus prey over maize pollen limited the predator's survival in the absence of the preferred diet and hence need to explore alternative substrates in citrus orchards to boost information on how to conserve the beneficial predator in citrus production.
