“…The layout of the crop is therefore one of the most important factors to consider when choosing an A. swirskii introduction method in a greenhouse. Buitenhuis et al (2010a) demonstrated that A. swirskii effectively stay on the potted ornamental plant on which they are released; approximately a quarter of the mites walked down the pot to the ground, but only a few individuals were recovered from adjacent pots. Only when plant canopies of adjacent pots were touching, A. swirskii freely moved between plants.…”

The predatory mite Amblyseius swirskii Athias-Henriot is a biological control agent that has the potential to play an important role in pest management in many greenhouse crops. Most research on this predatory mite has focused on its use and efficacy in greenhouse vegetables. However, an increasing number of growers of greenhouse ornamental crops also want to adopt biological control as their primary pest management strategy and find that biological control programs developed for vegetables are not optimized for use on floricultural plants. This paper reviews the use of A. swirskii in greenhouse crops, where possible highlighting the specific challenges and characteristics of ornamentals. The effects of different factors within the production system are described from the insect/mite and plant level up to the production level, including growing practices and environmental conditions. Finally, the use of A. swirskii within an integrated pest management system is discussed.

“…They cause direct damage when they extract plant fluids and indirect damage by transmitting viral pathogens (Byrne and Bellows 1991;Foster et al 2007). In this work, we have focused on three pest species of high agricultural importance: Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), Myzus persicae (Sulzer) (Hemiptera: Aphididae) and Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae) and on two predators commonly released in protected crops for controlling B.tabaci and other key-pests: Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) and Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) (Bosco et al 2008;Buitenhuis et al 2010;Colomer et al 2011).…”

Dispersal of aphids, whiteflies and their natural enemies under photoselective nets

et al. 2011

Integrated Pest Management of insects includes several control tactics, such as the use of photoselective nets, which may reduce the flight activity of insects. Limiting the dispersal of pests such as aphids and whiteflies is important because of their major role as vectors of plant viruses, while a minor impact on natural enemies is desired. In this study, we examined for the first time the dispersal ability of three vector species, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae) and Myzus persicae (Sulzer) (Hemiptera: Aphididae), in cages covered with photoselective nets. Contrary to the results obtained with aphids, the ability of the whitefly B. tabaci, to reach the target plant was reduced by photoselective nets. In a second set of experiments, the impact of UV-absorbing nets on the visual cues of two important predator species, Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) and Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae), was evaluated. The anthocorid was caught in higher numbers in traps placed under regular nets, whereas the mites preferably chose environments in which the UV radiation was attenuated. We have observed a wide range of effects that impedes generalization, although photoselective nets have a positive effect on pest management of whiteflies and aphids under protected environments.

“…As this mite originates from the Mediterranean basin, mostly found in humid coastal areas, A. swirskii prefer high temperatures and have a critical RH limit of ~70%, anything lower may cause their eggs to desiccate (de Moraes et al, 2004;Ferrero et al, 2010;Porath & Swirski, 1965). Buitenhuis et al (2010a) recently discovered that A. swirskii does not disperse well when applied to separated plants. Only a small percentage of the population applied to the upper foliage of the plant moved down to the soil in order to disperse through the greenhouse to neighbouring plants.…”

Seasonal climatic variations influence the efficacy of predatory mites used for control of western flower thrips in greenhouse ornamental crops

This research investigated seasonal climate changes within greenhouses and the impacts they have on efficacy of the predatory mites Amblyseius swirskii and Neoseiulus cucumeris. Controlled environment chamber, greenhouse small-cage, and commercial greenhouse trials were conducted to determine which biological control agent is more efficacious for control of the pest western flower thrips (WFT), (Frankliniella occidentalis) on ornamental crops.When observed under laboratory conditions, predation and oviposition were increased at higher temperatures. Photoperiod and light intensity also have an impact on predatory mites. Predation rates for both mite species were greater when subjected to short day light conditions (8 h light, 11 W/m 2 ). Climates typical of summer (higher temperature and light intensity, long day length) were most favourable in terms of predation and oviposition for A. swirskii. Neoseiulus cucumeris laid more eggs under short day as opposed to long day settings.In summer and winter greenhouse small cage trials, the performance of N.cucumeris and A. swirskii significantly reduced WFT numbers on potted chrysanthemum plants. However, in summer, A. swirskii provided significantly better thrips control than N. cucumeris. The number of adult mites recovered from plants was similar for both mite treatments in winter, while A. swirskii were present in higher numbers throughout the summer trials. Results from leaf damage assessments indicate that A. swirskii is more effective for control of heavy WFT feeding damage in both summer and winter. Results from commercial greenhouse trials yielded similar trends as those found in the summer and winter small cage trials.iii ACKNOWLEDGEMENTS
