“…The studies revealed predatory potential of S. scimitus against a harmful phytophage -western corn rootworm Diabrotica virgifera LeConte, 1868 (Coleoptera, Chrysomelidae). This mite prefers first-age larvae of D. virgifera rather than eggs (Pasquier et al, 2021). Diet of female D. virgifera does not affect the further dietary preferences of S. scimitus.…”

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.

“…The latter is known to feed on SCR eggs [60] and laelapid mites, including in the genus Stratiolaelaps, attack NCR and WCR eggs [63,64], with S. scimitus consuming WCR eggs under lab conditions [64]. However, Pasquier et al [110] did not find that S. scimitus attacked WCR eggs in lab experiments. Tyrophagus putrescentiae feeds on a wide variety of food, e.g., plants, stored products, fungi, and nematodes [80,81], and is able to adapt and persist on nutritionally-different diets [111] and tolerate some mycotoxins and plant-based spices [112], which could be why NCR egg consumption was similar among treatments for this mite species.…”

Landscape diversification with flowering plants can benefit pollinators and natural enemies, although insect pests can also use floral resources for nutrition and chemoprotection. Corn rootworms (Coleoptera: Chrysomelidae, Diabrotica spp.) are major pests of corn (Zea mays L.), and while subterranean larvae primarily feed on corn roots, adult rootworms commonly consume floral resources from other plant species. We quantified the species, density, and sex of adult corn Diabroticite rootworm beetles on wild and cultivated sunflower, corn, and squash, quantified pollen within the bodies of adult northern corn rootworms [NCR, D. barberi (Smith & Lawrence)], and investigated how consumption of sunflower and corn pollen by NCR adults impacted predation of their eggs by two soil-dwelling mites with different feeding specialization. NCR were the most common Diabroticite species on sunflower inflorescences and western corn rootworm (WCR, D. v. virgifera LeConte) were more abundant in corn and squash blossoms. Pollen feeding by NCR adults did not impact egg predation by omnivorous Tyrophagus putrescentiae (Schrank) (Acari: Sarcoptiformes, Acaridae), but predatory Stratiolaelaps scimitus (Womersley) (Acari: Mesostigmata, Laelapidae) ate eggs less frequently and took longer to feed on eggs from NCR females that had fed on sunflower pollen. This research suggests pollen feeding by adult NCR can impact predation of their eggs. While increasing plant diversity can benefit natural enemies and pest control within agroecosystems, it is important to consider how floral resources alter dietary preferences of biocontrol agents.

“…This creates direct damage leading to yield loss (Riedell 1990 ; Sutter et al 1990 ; Spike and Tollefson 1991 ; Godfrey et al 1993 ; Gray et al 2009 ). Laboratory studies showed promising results when testing predatory soil mites against this pest; field experiments, however, gave mixed results (Prischmann-Voldseth et al 2011 ; Prischmann-Voldseth and Dashiell 2013 ; Pasquier et al 2021a , b ).…”

Review: predatory soil mites as biocontrol agents of above- and below-ground plant pests

et al. 2022

Biological pest control is becoming increasingly important for sustainable agriculture. Although many species of natural enemies are already being used commercially, efficient biological control of various pests is still lacking, and there is a need for more biocontrol agents. In this review, we focus on predatory soil mites, their role as natural enemies, and their biocontrol potential, mainly in vegetable and ornamental crops, with an emphasis on greenhouse systems. These predators are still underrepresented in biological control, but have several advantages compared to predators living on above-ground plant parts. For example, predatory soil mites are often easy and affordable to mass rear, as most of them are generalist predators, which also means that they may be used against various pests and can survive periods of pest scarcity by feeding on alternative prey or food. Many of them can also endure unfavourable conditions, making it easier for them to establish in various crops. Based on the current literature, we show that they have potential to control a variety of pests, both in greenhouses and in the field. However, more research is needed to fully understand and appreciate their potential as biocontrol agents. We review and discuss several methods to increase their efficiency, such as supplying them with alternative food and changing soil/litter structure to enable persistence of their populations. We conclude that predatory soil mites deserve more attention in future studies to increase their application in agricultural crops.
