## Original research

### ABSTRACT

Phytoseiidae mites are represented by more than 2,700 species commonly found in plants and soil with some species widely used in biological control programs worldwide. Knowledge of mite diversity in pastures and interactions between Phytoseiidae and grasses is essential for developing more efficient and sustainable management techniques for this crop. Here, we present a survey of Phytoseiidae species in pastures from Goiás State, Brazil, to contribute to the knowledge of the diversity and abundance of these predatory mites. We sampled 15 country properties in the Cerrado domain that had pasture crops used for cattle farming, for a total of 480 samples, from eight different Poaceae species. We recorded 21 species from 10 genera, including 11 new records for Goiás and two species collected for the first time since their original descriptions, namely *Amblyseius atibaiensis* Mineiro, Lofego and Sato and *Proprioseiopsis biologicus* Lofego, Demite and Moraes. Only *Iphiseiodes zuluagai* Denmark and Muma, *Neoseiulus benjamini* (Schicha), *Proprioseiopsis mexicanus* (Garman) and *Proprioseiopsis biologicus* Lofego, Demite and Moraes had previously been reported in Brazilian pastures, while the remaining species are new records in these ecosystems. *Proprioseiopsis ovatus* (Garman), *N. benjamini* and *P. mexicanus* were the most abundant species, whereas only a single individual was found for *Amblyseius acalyphus* Denmark and Muma, *Amblyseius compositus* Denmark and Muma, *A. lofegoi*, *I. zuluagai*, *Neoseiulus gracilis* (Muma), *Metaseiulus* (*Metaseiulus*) *camelliae* Chant and Yoshida-Shaul and *Silvaseius barretoae* Yoshida-Shaul and Chant. These results highlight pastures as reservoirs for predatory mites, with potential for biological control in agroecosystems. However, further studies are necessary to better understand this diversity.

### Introduction

Phytoseiidae includes more than 2,700 valid species with 257 species recorded in Brazil (Demite et al. 2025). These mites occur primarily on plants (Schmidt 2013), but some species have also been found in soil samples (Moraes et al. 2024). Phytoseiids are natural predators of several phytophagous arthropod species and nematodes. Some species are also used in biological control programs to manage mite and insect pests on crops (McMurtry et al. 2013; Moraes et al. 2024). Because of these attributes, these mites are widely studied in several crops (Döker et al. 2023; Hyte et al. 2023; Möth et al. 2023).

Approximately 40.3% of the territory of the state of Goiás, Brazil, is represented by pastures used for livestock production (LAPIG 2023). Poaceae species are used for fodder and soil cover and are typically adopted by producers due to their high productivity (Shavanov 2021). Despite their ecological and agricultural relevance, studies on mites in Brazilian pastures remain scarce, particularly in the Cerrado biome (Flechtmann 2000, 2004; Flechtmann and Navia 2007; Lofego et al. 2009). Flechtmann (2000) described two new species, *Aceria aristidae* Flechtmann and *Aceria zoostrix* Flechtmann (Eriophyidae), on *Aristida* (Poaceae) in São Paulo. Flechtmann (2004) recorded 10 species of phytophagous mites occurring on *Urochloa ruziziensis* (R. Germ and C.M. Evrard) Crins (Poaceae) in the state of São Paulo, including description of two new species, namely *Catarhinus brachiariae* (Diptilomiopidae) Flechtmann and *Eotetranychus herbicolus* Flechtmann (Tetranychidae). Flechtmann and Navia (2007) reported the first occurrence of *Tetranychus (Armenychus) graminae* Flechtmann (Tetranychidae) in central Brazil, causing an elephant grass infestation. Furthermore, Lofego et al. (2009) recorded 21 phytoseiid mite species in Brazilian pastures, with the description of a new species, *Proprioseiopsis biologicus* Lofego, Demite and Moraes.

Understanding the biodiversity of agricultural systems is essential for elucidating the ecological interactions between mites and their host plants. Accordingly, our goal was to provide the first comprehensive survey of Phytoseiidae mites in cultivated pastures across Goiás State, documenting their diversity, abundance, and associations with their host grasses.

# Material and methods

## Study area

Phytoseiidae mites were sampled during the rainy season in pastures between November and December 2022 in 15 livestock farms from Brazabrantes, Caturaí, Inhumas, Itaberaí, Itauçu and Nova Veneza municipalities, Goiás State, Brazil. Between January and May of 2023, all the same farms were sampled once more, except for the Itauçu 1 (Figure 1, Table 1).

All farms sampled were in the Cerrado domain and grew pastures of the species *Cynodon nlemfuensis* Vanderyst, *Urochloa arrecta* (Hack. Ex T. Durand and Schinz) Morrone and Zuloaga, *Urochloa brizantha* (Hochst. ex A.Rich.) R.D. Webster, *Urochloa decumbes* (Stapf) R.D.Webster, *Urochloa humidicola* (Rendle) Morrone and Zuloaga, *Urochloa lorentziana* (Mez) Morrone and Zuloaga, *Urochloa plantaginea* (Link) R.D. Webster, and *Urochloa ruziziensis* (R. Germ. and C.M. Evrard) Crins (Poaceae) for livestock production.

## Mites collection

We randomly established five sampling plots on each livestock farm, totalizing 480 samples. Each plot was represented by a 1-square-meter area in the pasture where we collected grasses. At each sampling plot, we collected 2 L of grasses in a recipient, including all plant extensions such as stalks, nodes, internodes and leaves, except for rhizomes. Then, the sampled grasses were kept in individual paper bags (one bag per sampling plot) in a Styrofoam box with ice for transport. In the laboratory, the grasses were immersed in a 5 L container of 30% alcohol, which was shaken vigorously to release the Phytoseiidae mites from the plants. After this procedure, the grasses were removed, and the solution was transferred to a 25 µm mesh sieve. The mites that were trapped in the mesh were transferred to a pot containing 70% alcohol.

The samples were observed under stereomicroscope and all mites found were mounted on microscope slides using Hoyer's medium (Moraes *et al.* 2024). Phytoseiidae mites were counted and identified to the species level under a phase-contrast optical microscope using specialized dichotomous keys for genera and subgenera (Chant and McMurtry 2007) and works on descriptions, redescriptions, and revisions of Phytoseiidae (e.g., Barbosa and Demite 2023; Ferragut and Navia 2024; Lofego *et al.* 2024).

The list of mites collected in pastures from the state of Goiás, Brazil, includes the following information about the examined material: collection locality, grass species, month of sampling in Roman numerals, year in Arabic numerals, and the number of individuals of each sex (indicated by symbols ♀ and ♂). Additionally, the list provides previous records and observations. We extracted the previous records of Phytoseiidae species from the Phytoseiidae Database (Demite *et al.* 2025), available at: http://www.lea.esalq.usp.br/phytoseiidae.
## Results

We sampled 21 species from 10 genera of Phytoseiidae in pasture crops in Goiás State, Brazil. Among these, seven genera belonged to Amblyseiinae, and three to Typhlodrominae (Table 2).

Among the 21 species recorded, 11 are new records for Goiás State, and two were collected for the first time since their original descriptions, namely, *Amblyseius atibaiensis* and *Proprioseiopsis biologicus*.

In total, we collected 416 adult phytoseiid mites that were identified at the species level. The most abundant species was *Proprioseiopsis ovatus*, followed by *Neoseiulus benjamini* and *Proprioseiopsis mexicanus*. Only one individual was sampled for *Amblyseius acalyphus*, *Amblyseius compositus*, *Arrenoseius lofegoi*, *Iphiseiodes zuluagai*, *Neoseiulus gracilis*, *Metaseiulus (Metaseiulus) camelliae* and *Silvaseius barretoae*. Regarding host plants, *U. brizantha* hosted the highest richness and abundance of Phytoseiidae mites, followed by *U. plantaginea* and *U. decumbens* (Table 2). No phytoseiid mites were recorded on *U. lorentziana*. The following is a list of Phytoseiidae species sampled in pastures from livestock farms in Goiás State, Brazil.

**Discussion**

The grass species used for pastures in Goiás State act as reservoirs for predatory mites. In the present study, 21 Phytoseiidae species were recorded in pastures used for livestock. These results were similar to the findings of Lofego *et al.* (2009), which in turn, reported 21 phytoseiid mites on grasses of the species *U. decumbens*, *U. brizantha*, *U. ruziziensis*, *Melinis minutiflora*, *Urochloa lorentziana*, and *Pennisetum purpureum* in São Paulo State. Previous studies on native plants in the Cerrado recorded 34 species of Phytoseiidae (Demite *et al.* 2017), while another survey reported 26 species of mites from the same family (Rezende and Lofego 2011). In the Pantanal biome, Mendonça *et al.* (2019) reported 35 Phytoseiidae species associated with native trees. Additionally, collections carried out in the Cerrado, Pantanal, and Amazon Forest recorded nine, 16, and 11 species, respectively (Conceição *et al.* 2021), while another sampling in the same biomes recorded five, five, and 17 phytoseiid species, respectively (Demite *et al.* 2021). Rossetti *et al.* (2025) recorded 19 phytoseiid species in remnants of Cerrado vegetation in the state of Goiás. Thus, pasture areas, although simplified ecosystems, can exhibit considerable diversity when compared to natural vegetation remnants.

Among Phytoseiidae species sampled, only *I. zuluagai*, *N. benjamini*, *P. mexicanus* and *P. biologicus* have been previously reported in Brazilian grasslands (Lofego *et al.* 2009). For the remaining species, this study provides the first record in Brazilian pasture crops. *Proprioseiopsis ovata* was the most abundant species in the evaluated pastures. Species from this genus are widely used in natural biological control. For example, *P. mexicanus*, the third most abundant phytoseiid species sampled here, is a generalist predator with the potential to control arthropod pests (Yuan *et al.*, 2025). *Proprioseiopsis mexicanus* has also been recorded at high abundances during the wet season (Mailloux *et al.* 2010). *Neoseiulus benjamini* was the second most abundant species in pastures from livestock farms in Goiás State. This species was previously reported on monocotyledonous plants from the families Poaceae and Cyperaceae (Demite *et al.* 2017; Ferragut and Navia 2022).

Our results showed that Poaceae crops support a rich assemblage of Phytoseiidae species. Therefore, assessing the biodiversity in pastures is essential for crop management, as these grass species are widely used for soil cover in Brazilian agroecosystems (Flechtmann 2004; Aguilar-Fenollosa *et al.* 2011; Blanco-Pérez *et al.* 2020). These results highlights the importance of avoiding farm management practices that affect predator populations (Farfan *et al.* 2021). However, more studies are necessary to increase our knowledge of the biodiversity associated with pasture crops and the interactions between mites and grasses.
