https://doi.org/10.24349/1031-yup9The family Phytoseiidae is composed of several predatory species, with some ones used in biological control. These mites are naturally found on the leaves of various plants, where they find food and shelter (Moraes and Flechtmann 2008). Many of these mites feed not only on prey (which are largely phytophagous mites), but also on pollen, plant exudates, and fungi (McMurtry and Croft 1997). The genus Euseius is a good representative of this type of predator, classified by McMurtry et al. 2013 as type IV predatory mites, that is, generalist predators that use pollen as an important part of their diet. The species Euseius citrifolius Denmark and Muma was described from specimens collected in Paraguay by Denmark and Muma in 1970, and since then, many records of this species have been noted in the Neotropics, especially in Brazil (Lofego et al. 2024; Demite et al. 2026). These records often show co-occurrences with several species of phytophagous mites (Oliveira et al. 2012; Montes et al. 2012; Barroso et al. 2019). This species has a rapid life cycle that completes in seven days, from egg to adult stage, although it may be faster depending on its diet (Furtado and Moraes 1998). Some studies demonstrate that E. citrifolius performs well in preying on some species of phytophagous mites, especially those belonging to the family Tenuipalpidae (De Vis et al. 2006; Cardoso et al. 2010; Cano 2020; Amaral 2022). Considering these characteristics, E. citrifolius could be a promising species for use in integrated pest management programs, whether in augmentative biological control or especially for conservation control. According to Tixier (2018), to implement conservation biological control, it is necessary to study certain characteristics of predatory mites, including the presence of the predator on reservoir plants and its dispersal capacity between reservoir plants and the crops. According to Bellini et al. (2008), E. citrifolius was present not only on cultivated rubber trees but also on spontaneous euphorbiaceous plants within the crop. In coffee cultivation, Ferla et al. (2023) also found that this predator was present both on coffee and in intercropped plants. Furthermore, Araújo et al. (2022) demonstrated that the abundance of predators, including E. citrifolius, is positively influenced by the heterogeneity and complexity of the habitat in rubber tree plantations. Thus, as suggested by these studies and following the proposition of Tixier (2018), E. citrifolius seems to have some of the characteristics necessary to be implemented in conservation biological control programs.
In this scenario, considering its widespread and frequent occurrence, its good predatory capacity against pest mites, its presence in cultivated and uncultivated plants, and its presence in a variety of climates and habitats in South America and especially in Brazil, E. citrifolius emerges as a predatory species of great importance for conservative biological control of agricultural pests. However, despite these attributes, there is no literature review study for this species that could provide a basis and direction for further studies. In this context, this study aimed to fill this gap, seeking to evaluate what is already consolidated knowledge, and knowledge gaps.
Searches were conducted using the keyword ''Euseius citrifolius'' in the following databases: Scielo, PubMed, Database Phytoseiidae (Available on: https://www.lea.esalq.usp.br/phytoseiidae
), and Capes Periodicals. Scientific articles, theses, and dissertations were considered to obtain the data. To better assess the topics of the studies on E. citrifolius, the information found was classified into three categories: occurrence and distribution, morphological and molecular characterization, and bioecology. Publications available up to December 18, 2025, were considered.
Some studies were considered in more than one category. The term ''occurrence'' is used for the related presence of the species in plants.
The geographical coordinates were taken directly from the studies when available, or approximate coordinates were used when only the name of the collection site was provided. Geographic data were disregarded when they were nonspecific to the species or when they were too broad. The map was created using the QGIS 3.24.1 program.
The correct spelling of the scientific names of the plants mentioned in this study, as well as information on their family, plant type, and whether they are native or introduced, was verified and obtained from the REFLORA (Available on: https://reflora.jbrj.gov.br/consulta
) and Plant of the World Online – POWO (Available on: https://powo.science.kew.org
) platforms. To determine whether plant species are cultivated or not, the information was checked in POWO and in the National Register of Cultivars (RNC) (Available on: https://sistemas.agricultura.gov.br/snpc/cultivarweb/cultivares_registradas.php
?) for plants found in Brazil. Cultivated plants were defined as any plant maintained or planted by humans for various uses (Kinlock et al. 2025).
A total of 104 publications with data related to E. citrifolius were found. The majority (89 – 85%) deal with some data about occurrence and/or distribution. Fifteen studies (13%) concerned morphological and molecular characterization, of which only two focused on molecular characterization. The remaining eight percent are biology studies, represented by only nine papers.
The first publication dates to 1970, containing a description and first reports of E. citrifolius in citrus orchards (Denmark and Muma 1970). It was not until 12 years later that another publication on the species was recorded, marking the first study of its biology (Moraes and McMurtry 1981). Since then, there have been a few publications, and from the 2000s onwards, publications have been produced every year, reaching up to 7 publications in a single year (Figure 1).
Across these 104 publications, approximately 160 researchers and more than 50 institutions worked with this species. Most of the publications originated from Brazilian groups or were produced in collaboration with them, notably involving the Acarology Laboratory at ESALQ, Piracicaba and the Acarology Laboratory at UNESP, São José do Rio Preto.
Eighty-nine studies containing information on the occurrence and geographic distribution of E. citrifolius were found and evaluated. These studies reveal records of this species only in South and Central American countries: Argentina, Brazil, Colombia, Paraguay, Peru, and Nicaragua. Most of them are from Brazil, with records in 19 of the 26 Brazilian states (Figure 2).
Of all the studies analyzed in this research, 84 contained information on the number of mites found; of these, 79 reported co-occurrence of E. citrifolius with other species of the same genus. In 60% of these studies, E. citrifolius was the most abundant mite compared to other species of the genus, such as Euseius alatus De Leon, Euseius concordis (Chant), and Euseius sibelius (De Leon) although these other species have been recorded in more or the same countries and regions as E. citrifolius. Thus, these data show that when present, E. citrifolius is quite abundant, and can co-occur with other predators.
Euseius citrifolius was found on 226 plant species, belonging to 56 families and 63 genera (Table 1). The most reported species are cultivated plants, only 21 are non-cultivated and native plants. Also, the species occurs more in native plants than introduced ones. Besides that, the most plants are trees or shrub/tree, but E. citrifolius can occurs in various types of plants like grasses, lianas and herbs (Table 1).

The families with the highest occurrence are Fabaceae, Solanaceae, Euphorbiaceae and Arecaceae (Figure 3). Among host plants, many are of economic importance, such as: coffee (Mineiro et al. 2006a, b), coconut (Barroso et al. 2019), citrus (Ferreira et al. 2018), banana (Barroso et al. 2019), rubber tree (Daud and Feres 2013), grapevine (Domingos et al. 2014), peach (Montes et al. 2011), jatropha (Lofego et al. 2013), guava (Denmark and Muma 1970) and tomato (Furtado et al. 2014). In the literature this species was more reported in rubber trees (12 reports), guava (8 reports), coffee (8 reports), citrus (5 reports) and peach (5 reports) (Table 1).
These plants, in monoculture systems, often present phytophagous mite pests, such as Raoiella indica Hirst on coconut and banana cultivars, Brevipalpus phoenicis (Geijskes) on citrus and coffee plantations, Tenuipalpus heveae Baker on rubber tree plantations, among others. E. citrifolius has previously been reported in the literature as co-occurring with all these species (Demite and Feres 2005; Bellini et al. 2008; Montes et al. 2012; Abreu et al. 2014; Mineiro and Raga 2020; Barroso et al. 2019; Ferla et al. 2023). In studies showing its co-occurrence with R. indica (Barroso et al. 2019) and in those with B. phoenicis (Montes et al. 2012; Abreu et al. 2014), E. citrifolius was the most abundant predatory mite. Furthermore, Montes et al. 2012 suggest that the presence of this predator in peach orchards may have accounted for the low density of phytophagous mites found in their study.
In addition, this predator occurs in several plants considered reservoirs and commonly used in intercropping systems, such as Inga edulis Mart. (Fabaceae) (Ferla et al. 2023), Swietenia macrophylla King (Meliaceae) (Demite et al. 2021), Urochloa brizantha (A.Rich.) R.D.Webster (Poaceae) (Lofego et al. 2009). Thus, understanding this predator's locomotion across different environments and plant communities, and especially its impact on pest species, is fundamental.
Denmark and Muma (1970) described E. citrifolius from specimens collected in Asunción, Paraguay. Following this work, twelve other studies presented new morphological data, such as structural measurements of the populations studied and illustrations, for this species (Moraes and McMurtry 1983; Feres and Moraes 1998; Gondim and Moraes 2001; Noronha and Moraes 2002; Lofego et al. 2004; Guanilo et al. 2008 a, b; Lofego et al. 2009; Demite et al. 2017; Lofego et al. 2024; Castro et al. 2024). All these studies demonstrate the existence of intraspecific morphological variability, as initially observed by Noronha and Moraes (2002). The variation was less or equal to 10% in comparison with the original description for shields and about 10 or 15% for setaes, but always the difference was less than 10 µm. This difference could be considered a normal intraspecific variation (Tixier 2013).
Noronha and Moraes (2002) suggested that morphological variation may be linked to the geographical differentiation, with an effect of the location where the population was collected. This hypothesis is consistent with observations in literature for this species and shown in Table 2. These data (Table 2) show that in comparison with the original description population, the population of São Paulo, Peru and Argentina has the longer body length. Besides that, populations from the state of São Paulo tend to have slightly longer body length than populations from other regions of Brazil, especially in comparison with regions geographically more distant. One possible explanation for this is that abiotic factors like altitude, temperature, seasonality and precipitation can influence the body size (Yu et al. 2025; Tixier et al. 2003). The effect of temperature in morphology was demonstrated for Euseius concordis (Chant) (Lopes et al. 2018) and Amblydromalus limonicus (Garman & McGregor) (Vangansbeke et al. 2020). In both studies the mites have higher body length at low temperatures. This can explain part of the variation morphology found in this review.
In addition to local climatic characteristics, another factor that could explain the differences found would be the diet of these mites in natura. Ferreira et al. (2021) observed that for Neoseiulus tunus (De Leon), diet plays an important role in modifying morphological measurements, both of shields (ventrianal shield and width of dorsal shield) and setae. This same observation was made by Lopes et al. (2018) for E. concordis. Besides that, the host plants can influence in the morphological variation, as suggested for Typhlodromus (Anthoseius) recki Wainstein (Tixier et al. 2021) and Kampimodromus aberrans (Oudemans) (Tixier et al. 2003). Thus, given that morphological measurements can apparently vary with the environment in which an individual lives, characterizing the extent of this intraspecific variation is extremely important, as these measurements are used as diagnosis for species differentiation. Furthermore, it would be interesting to verify whether there are differences in bioecological parameters between these populations with different morphological traits.
Although morphological variability exists in E. citrifolius, molecular studies based on ITS1 and ITS2 markers also suggest that this represents intraspecific variation, given the low or nonexistent genetic difference between the populations studied (Noronha et al. 2003). However, molecular studies using other markers to provide taxonomic information, including for other populations, might be interesting to carry out.
Another molecular characterization of E. citrifolius was, conducted by Santos and Tixier (2018), in which they considered six molecular markers to elucidate the likely ancestral region and phylogenetic relationships of the Euseiini tribe. This study indicates that the ancestor of the genus Euseius is possibly from the Neotropical region. Furthermore, the authors classified as belonging to Clade I and with a higher occurrence in the plant families Euphorbiaceae, Rosaceae, Rutaceae, and Solanaceae. These same families were found here for E. citrifolius, but the highest records are Fabaceae, Solanaceae, Euphorbiaceae and Arecaceae. Across all these families, E. citrifolius is recorded on both cultivated plants (majority) and non-cultivated ones. Furthermore, the species was found on 30 native plant species belonging to the families Euphorbiaceae (15) and Solanaceae (15) (Table 1). These records align with the findings of Santos and Tixier (2018), indicating that these families may be associated with the center of diversification for Euseiini species in South America.

A total of nine studies on bioecological parameters related to E. citrifolius were found. Among them, only four evaluated the complete life cycle of this predatory mite (Moraes and McMurtry 1982; Furtado and Moraes 1998; Amaral 2022; Domingos et al. 2025). In these studies, E. citrifolius was able to complete its development cycle by feeding on the following phytophagous mites: Tetranychus urticae (Koch), Tetranychus pacificus McGregor, Mononychellus tanajoa (Bondar), Oligonychus punicae (Hirst) and Tenuipalpus heveae. Furthermore, Furtado and Moraes (1998) observed that when fed Typha angustifolia L. pollen, E. citrifolius had a shorter generation time and higher rates of reproduction, growth, oviposition, and longevity than when fed T. urticae and M. tanajoa. However, Amaral (2022), in a study with another population and with T. heveae as food, showed even higher rates of reproduction, growth, oviposition, and longevity than those found by Furtado and Moraes (1998) for prey and pollen. Domingos et al. (2025) also demonstrated that E. citrifolius has a higher reproduction rate when fed with O. punicae and T. urticae than with pollen from Ricinus communis L (Euphorbiaceae). Thus, although the populations tested were different and the conditions also, these studies demonstrate that E. citrifolius can complete its life cycle with a variety of foods, including mite pests and pollen.
Six other studies evaluating only E. citrifolius predation on the following prey: Brevipalpus phoenicis (Tenuipalpidae) (Gravena et al. 1994), Oligonychus ilicis (McGregor) (Tetranychidae) (Franco et al. 2010), Tenuipalpus heveae (Tenuipalpidae) (Cardoso et al. 2010; Amaral 2022), Raoiella indica (Tenuipalpidae) (Cano 2020), Calacarus heveae Feres (Eriophyidae) (Amaral 2022), Eutetranychus banksi McGregor (Tetranychidae) (Amaral 2022) and Frankliniella sp. (Thysanoptera: Thripidae) (De Vis et al. 2006) (Table 3). In all these studies, the authors demonstrated that E. citrifolius might possibly play an important role in the control of these pests. Among these studies and among the species tested, the highest predation rate was observed on R. indica (Cano 2020), with a consumption of 52.03 ± 4.50 eggs/female/day. This predation rate is like that found for the predatory mite Neoseiulus barkeri Hughes (56.2 ± 2.0) when fed on this same prey and which is commercially available for inundate biological control of this pest but does not occur naturally in Brazilian and neotropical agroecosystems (Filgueiras et al. 2020). Thus, these studies demonstrate the potential of E. citrifolius as a biological control agent.

De Vis et al. (2006) evaluated the oviposition and survival of E. citrifolius with different foods, namely: B. phoenicis, T. heveae, C. heveae, T. urticae, Oligonychus gossypii (Zacher) and T. angustifolia. They obtained slightly higher oviposition results when E. citrifolius was fed with mites of the family Tenuipalpidae than when fed with pollen from T. angustifolia or mites from the families Tetranychidae and Eriophyidae (Table 4). Similar results were found by Amaral (2022) in which, despite the wide variety of pollens tested (Table 4), E. citrifolius obtained higher oviposition when fed with the mite T. heveae (Tenuipalpidae). Available data demonstrate that the best predation rates for E. citrifolius were achieved when tests were conducted with a high prey density and when the offered prey was Tenuipalpidae. Biological data on this species when fed on T. heveae also demonstrate that this predatory mite could develop using only this prey as food and showed good growth, reproduction, and longevity rates.
In addition to occurring in various regions and hosts, as already indicated previously, studies with an ecological focus have indicated the capacity of E. citrifolius to occur in variable environmental conditions, being able to occur throughout the year in a given area, demonstrating adaptation to climatic variations that occur throughout the year (Lofego and Moraes 2006; Demite et al. 2011; Abreu et al. 2014). The species is also found in diverse biomes -such as Atlantic Forest, Amazon, Caatinga, Pantanal, and Cerrado (Zacarias and Moraes 2001; Lofego and Moraes 2006; Demite et al. 2011; 2017; Rezende and Lofego 2011; Mendonça et al. 2019; Conceição et al. 2021; Rodrigues et al. 2020), in well as in uncultivated areas (Feres et al. 2007; Lofego and Moraes 2006; Lofego et al. 2017; Demite et al. 2011; 2013), or more disturbed environments, such as agroecosystems and even urban areas (Daud and Feres 2005; Montes et al. 2012; Abreu et al. 2014; Lofego et al. 2013). Furthermore, studies show that E. citrifolius can be present in environments and on plants with insecticide applications (Hesketh and Sato 2023), showing a possible adaptability of this predator, as already shown for other predatory mites (Argolo et al. 2014; Salman et al. 2015; Serra et al. 2026). Bioecological data indicate that E. citrifolius is a resilient predatory mite that could exert pest control across diverse environment, making it a key species in conservation biological control. Other Euseius species have proven important in controlling multiple pests; for instance, Euseius stipulatus (Athias-Henriot) and Euseius sojaensis (Ehara) are significant in citrus orchard. Euseius stipulatus has been successfully used in classical biological control programs in Peru (Vásquez et al. 2023; Santana-Mayorga et al. 2025) and the United States (McMurtry et al. 2015). However, it yielded less successful results against E. banksi in Spanish citrus orchard, likely due to the consumption of alternative food sources and intraguild predation (Abad-Moyano et al. 2010; López-Olmos and Ferragut 2024). Euseius sojaensis has proven important for the conservation biological control of Panonychus citri (McGregor) (Acari: Tetranychidae) and Aculops pelekassi (Keifer) (Acari: Eriophyidae) in Japan, demonstrating population growth and successful pest control when supported by pollen-producing plants (Tsuchida and Masui, 2025). Meanwhile, Euseius amissibilis Meshkov showed promise in controlling Trialeurodes vaporariorum (Gennadius) (Hemiptera: Aleyrodidae) and Frankliniella occidentalis (Pergande) on greenhouse roses; however, in semi-field trials involving pollen, it failed to effectively control thrips while maintaining efficacy against whiteflies (Van Houten et al. 2016). Thus, understanding the field behavior of a predatory species, particularly a generalist like those in the Euseius genus, is crucial for establishing its effectiveness as a biological control agent. Therefore, further field studies on E. citrifolius are needed to better evaluate its role in maintaining control over phytophagous mites.
In general, this review demonstrates that most studies involving E. citrifolius focus on occurrence records, indicating a wide distribution in Brazil and with some records in other countries like: Argentina, Colombia, Paraguay, Peru and Nicaragua. We also observed that this predator is most commonly found on the plant families Fabaceae, Solanaceae, Euphorbiaceae, and Arecaceae and the species compiled in this review can be used as a guide for searching for this species in natura, or for choosing the best plants as reservoirs in integrated cropping programs.
There are also a good number of studies on morphological characterization, thus allowing the recognition of morphological variations and facilitating the identification of this species.
Bioecological studies have shown that, in addition to being frequent, E. citrifolius is often the most abundant predator in some environments. Furthermore, these studies demonstrate that this predator can complete its life cycle and have a population increase by consuming various types of prey and pollen. Judging by the studies already carried out, considering the frequency, abundance, and predation potential of phytophagous mites, it is presumed that E. citrifolius could play a role in the control of mite pests in some preserved environments and agroecosystems.
Despite this, important information is lacking for this predator to be used in pest control programs, such as field studies, with no studies having been performed, as well as more studies on food preferences. Since this predator is a generalist, it is also important to understand its predation potential in relation to different types of prey that have not yet been studied, to understand its possible range of action, as well as to verify its acceptance of alternative foods to improve mass breeding strategies and maintain the predator in the field.
Another gap in knowledge about this species is the molecular characterization of populations. In our searches, we found only one study on the subject, and in that study, only two nuclear markers were used. Thus, studies involving mitochondrial markers to better assess molecular differences between populations would be interesting.
Finally, we can conclude that E. citrifolius is an abundant species that have demonstrated a good predatory capacity, especially with Tenuipalpidae mites. This reinforces the potential of this species as a natural enemy of various agricultural pests and the importance of including it in pest management programs.
