AbstractThe relationships between the predatory mites, Amblyseius swirskii (Athias-Henriot) and Neoseiulus cucumeris (Oudemans) (Acari: Phytoseiidae), and their prey, western flower thrips (Frankliniella occidentalis Pergande) (Thysanoptera: Thripidae), were investigated to determine the effects of predation on intra-guild or extra-guild prey and predator preference. Life history characteristics of both predatory mites were measured when fed eggs and larvae of the other predator species and compared to data obtained when the predators were fed thrips larvae. In addition, choice tests were conducted to determine if the predators had a preference for different prey or if they were indiscriminate predators. Amblyseius swirskii appears to be an important intra-guild predator of N. cucumeris juveniles because of a high predation rate and a preference for N. cucumeris juveniles over thrips. Neoseiulus cucumeris is also an intra-guild predator of A. swirskii juveniles; however, it has a lower predation rate than A. swirskii. Contrary to intra-guild predation theory, intra-guild prey was an equally good or better food source than thrips (extra-guild prey) for both predators, based on high oviposition rates and fast development times. The results of this study indicate a high potential for negative interactions between A. swirskii and N. cucumeris when used together in biological control of thrips.

In-lab rearing of the predatory mites Amblyseius swirskii and Neoseiulus cucumeris on the fodder mites Tyrophagus putrescentiae and Carpoglyphus lactis has been assessed. The study was performed for species kept separately and together. All trials were carried out in 5-fold replications during 25 days at temperature 23–25 °C, the length of daylight of 18 hours, and relative humidity of 85–90 %. After 25 days, T. putrescentiae outnumbered C. lactis in 1.3 times while reared separately, and in 118 times in cases when they were reared together. After 25 days of rearing the predatory mites N. cucumeris and A. swirskii together the first one outnumbered the second one in 9.1 times while feeding on T. putrescentia and in 3.2 times while feeding on C. lactis. The possibility of in-lab rearing of N. cucumeris on both species of the fodder mites was shown, while A. swirskii feeding on T. putrescentiae demonstrated the increase of its density during first two weeks only. Neoseiulus cucumeris is more competitive than A. swirskii because it can achieve high density on different species of fodder mites. Different species of mites must be strictly isolated from each other during their rearing to prevent contamination.

Predatory mites Amblyseius swirskii and Neoseiulus cucumeris are considered as effective biocontrol agents against whitefly and thrips in indoors on vegetable crops. Our goal was to assess the effect of these predatory mites on whitefly density on roses indoors in the North-West of Russia. Result showed that the dynamics of the pest population is affected not only by the predator release rate, but also by the time between introductions and their frequency. There was no difference between two species, except one case, when temperatures had risen above 27°C and consequently A. swirskii had a bigger impact on whiteflies than N. cucumeris.

AbstractRecent studies have shown that predatory mites used as biocontrol agents can be loaded with entomopathogenic fungal conidia to increase infection rates in pest populations. Under laboratory conditions, we determined the capacity of two phytoseiid mites, Amblyseius swirskii and Neoseiulus cucumeris to deliver the entomopathogenic fungus Beauveria bassiana to their prey, Frankliniella occidentalis. Predatory mites were loaded with conidia and released on plants that had been previously infested with first instar prey clustered on a bean leaf. We examined each plant section to characterize the spatial distribution of each interacting organism. Our results showed that A. swirskii delivered high numbers of conidia to thrips infested leaves, thereby increasing the proportion of thrips that came into contact with the fungus. The effect was larger when thrips infestation occurred on young leaves than on old leaves. Neoseiulus cucumeris delivered less conidia to the thrips infested leaves. These patterns result from differences in foraging activity between predatory mite species. Amblyseius swirskii stayed longer on plants, especially within thrips colonies, and had a stronger suppressing effect on thrips than N. cucumeris. Our study suggests that loading certain predatory mite species with fungal conidia can increase their capacity to suppress thrips populations by combining predation and dispersing pathogens.

Abstract Learning is changed behavior following experience, and ubiquitous in animals including plant-inhabiting predatory mites (Phytoseiidae). Learning has many benefits but also incurs costs, which are only poorly understood. Here, we addressed learning, especially its costs, in the generalist predatory mite Amblyseius swirskii, a biocontrol agent of several herbivores, which can also survive on pollen. The goals of our research were (1) to scrutinize if A. swirskii is able to learn during early life in foraging contexts and, if so, (2) to determine the costs of early learning. In the experiments, we used one difficult-to-grasp prey, i.e., thrips, and one easy-to-grasp prey, i.e., spider mites. Our experiments show that A. swirskii is able to learn during early life. Adult predators attacked prey experienced early in life (i.e., matching prey) more quickly than they attacked unknown (i.e., non-matching) prey. Furthermore, we observed both fitness benefits and operating (physiological) costs of early learning. Predators receiving the matching prey produced the most eggs, whereas predators receiving the non-matching prey produced the least. Thrips-experienced predators needed the longest for juvenile development. Our findings may be used to enhance A. swirskii’s efficacy in biological control, by priming young predators on a specific prey early in life.
