“…Gaeolaelaps aculeifer (Canestrini) and Stratiolaelaps scimitus (Womersley) are predatory, soil-dwelling mites belonging to the family Laelapidae (Acari: Mesostigmata). Typically, these two species are generalist predators and are used effectively as biological control agents of various soil pests, such as thrips pupae, fly maggots, and bulb mites [1][2][3][4][5][6][7]. Moreover, these two predatory mites are beneficial for controlling mushroom flies during mushroom cultivation [3,[8][9][10], and control poultry red mite, Dermanyssus gallinae (De Geer) [11,12].…”

Predatory soil-dwelling mites, Gaeolaelaps aculeifer (Canestrini) and Stratiolaelaps scimitus (Womersley) (Mesostigmata: Laelapidae), are essential biocontrol agents of small soil arthropod pests. To understand the population characteristics of these two predatory mites, we investigated their development, survival, and fecundity under laboratory conditions. We used Tyrophagus putrescentiae (Schrank) as a food source and analyzed the data using the age-stage, two-sex life table. The duration from egg to adult for G. aculeifer was longer than that for S. scimitus, but larval duration was similar between the two species. Notably, G. aculeifer laid 74.88 eggs/female in 24.50 days, but S. scimitus laid 28.46 eggs/female in 19.1 days. Several population parameters, such as the intrinsic rate of increase, finite rate of increase, net reproductive rate, and gross reproductive rate of G. aculeifer, were significantly higher than those of S. scimitus. Using the bootstrap technique with 100,000 samples, we demonstrated that the life tables constructed based on the 2.5th and 97.5th percentiles of finite rate of increase (λ) net reproductive rate (R0) may characterize the variability in the survival and fecundity curves, as well as predict population growth uncertainty. These data provide important information for the practical application of predatory soil mites to manage agricultural pests.

“…The predatory soil mite S. scimitus is broadly utilized for the control of various phytophages and parasites (Schilliger et al, 2013;Mendyk, 2015;Duarte et al, 2020Duarte et al, , 2021Yan et al, 2021Yan et al, , 2022. Because of their ability to live with no food for 60 days (Wright & Chambers, 1994), this zoophage can maintain a minimum number of phytophages in the soil (Park et al, 2021b) and completely clear parasitic red velvet mites off reptiles (Trombidiformes, Trombiculidae) in terrariums (Schilliger et al, 2013;Mendyk 2015). Ali et al (2012) determined that temperatures above 22 ºC positively influence the predation of S. scimitus; in 24 h, this zoophage destroyed 40% of population of Dermanyssus gallinae (De Geer, 1778) (Mesostigmata, Dermanyssidae), and therefore it may be used in poultry farms for protection of laying hens (Ali et al, 2012).…”

Stratiolaelaps scimitus (Womersley, 1956) (Acari, Mesostigmata, Laelapidae) is a predatory soil mite massively produced in laboratories in many countries of the world. The existing spheres of S. scimitus application vary in many parameters, especially temperature and relative humidity. In this article, we analyzed temperature and humidity appropriate for fastest spread of soil predatory mite S. scimitus. Mites should be released to a new environment in such a way that they would distribute in a greenhouse, garden or field as fast as they can (i.e. providing maximum migration activity of S. scimitus), on the one hand, and provide maximum efficient control of number of target phytophage species (i.e. providing maximum trophic activity), on the other hand. In our experiment, at 14 ºC temperature, most specimens of S. scimitus did not leave the migratory circle for 10 seconds. In 15–19 ºC range, only 14.7% of mites left the migratory circle, and their examined activity in 10 s was only 5–10 mm. In 20–24 ºC range, 27.5% of mites left the migratory circle, their migratory activity increased to 15–23 mm. In 25–33 ºC range, the moving activity increased even more, the mites left the migratory circle at the first opportunity that had (some even jumped off the circle to the experimental field), 95.8% of the mites left the circle in 10 s, their examined activity reached 25–60 mm in 10 seconds. Study of thermo- and hygro-preferences for various groups of invertebrates helps to better describe their ecological niche in multidimensional space of ecologic factors.

“…Predation rates of G. aculeifer and P. bituberosus on T. tabaci were higher than those reported for laelapid species feeding on F. occidentalis. Specifically, Stratiolaelaps scimitus (Womersley) consumed 2.13 ± 0.1 prey/day (Park et al 2021) and 4.5 ± 0.42 prey/day , G. aculeifer 2.93 ± 0.1 prey/day (Park et al 2021) and 3.5 ± 0.5 prey/day (Berndt et al 2004b), G. aculeifer (the same strain used in the present study) 2.6 ± 0.1 prey/day (Rueda-Ramírez et al 2018), Stratiolaelaps miles (Berlese) 1.6 ± 0.3 prey/day (Berndt et al 2004a) and Cosmolaelaps jaboticabalensis (Moreira, Klompen and Moraes) 2.6 ± 1.1 prey/day (Moreira et al 2015). In addition, Park et al (2021) reported predation rate of G. aculeifer and S. scimitus of 2.4 ± 0.1 and 2.0 ± 0.1 prey/day when these species were fed with F. intonsa (Tryborn), and of 3.3 ± 0.1 and 3.4 ± 0.1 when fed on Thrips palmi (Karny), respectively.…”

Predation and oviposition rates of Gaeolaelaps aculeifer and Parasitus bituberosus (Acari: Laelapidae and Parasitidae) on pre-pupae/pupae of Thrips tabaci (Thysanoptera: Thripidae)

Thrips tabaci Lindeman is one of the main insect pests of onion (Allium cepa L.) in Colombia and several other countries. Strategies for its control are currently based on the use of chemical products. In a recent survey, Gaeolaelaps aculeifer (Canestrini) and Parasitus bituberosus Karg, two soil-dwelling predatory mite species (Acari: Mesostigmata), were found associated with this crop at Boyacá department, Colombia. Given that T. tabaci spends its pre-pupal and pupal stages in the soil, this study was conducted to evaluate the predation and oviposition of G. aculeifer and P. bituberosus on these developmental stages under laboratory conditions. The predators consumed up to 6.8 ± 0.52 and 6.9 ± 0.45 T. tabaci pre-pupae/ pupae, respectively, when offered 6 –10 prey a day. The maximum oviposition rates were 4.4 ± 0.25 eggs/female/day for G. aculeifer and 6.9 ± 0.26 eggs/female/day for P. bituberosus, with a mean egg viability higher than 91% for both predators. These results suggest that the evaluated predators may affect the population of T. tabaci under field conditions, and that the conduction of complementary studies on those predators is warranted, envisioning their practical use for T. tabaci control in Colombia.
