“…Previous studies in Europe and United States of America found that N. cucumeris could provide satisfactory control of P. pallidus with a single introduction (Croft et al 1998;Petrova et al 2000;Easterbrook et al 2001;Tuovinen et al 2009), but our study did not entirely corroborate these findings. Neoseiulus cucumeris did offer adequate control of P. pallidus in August, but was less effective at the beginning and at the end of the season.…”

“…Therefore, the efficacy of in-field biocontrol is difficult to predict. Moreover, early introduction, a key factor in P. pallidus biocontrol (Easterbrook et al 2001;Svensson 2008;Tuovinen et al 2009), proves to be a challenge in regions under temperate climate such as Québec. Past studies have pointed out that introduction rates and frequency should be temperature-adapted to maintain the same level of efficacy (Jones et al 2005;Svensson 2008), but this strategy can become expensive and uneconomical for producers.…”

The cyclamen mite (Phytonemus pallidus Banks; Acari: Tarsonemidae) has recently become a more important pest in Canadian strawberry (Fragaria × ananassa Duchesne ex Rozier; Rosaceae) production with the withdrawal of the pesticide endosulfan in 2016, yet its phenology under field conditions in Canada is poorly known. Moreover, while its biological control with predatory mites has shown potential, the effectiveness of this method has never been investigated under eastern Canadian field conditions. The objectives of this study were to (1) monitor populations of P. pallidus in strawberries for two consecutive years; and (2) evaluate the in-field potential of the predatory mite Neoseiulus cucumeris Oudemans (Acari: Phytoseiidae). Monitoring cyclamen mite populations in the field revealed new critical knowledge about its phenology in eastern Canada, such as activity until late November. The predator N. cucumeris was able to effectively suppress cyclamen mites the first year, but appeared to be too cold-sensitive to maintain adequate control towards the end of the season. Furthermore, the high rates of predator release required would most likely be cost prohibitive for commercial use. Control of the cyclamen mite in strawberries remains a complex issue that will require further research.

“…Other predatory mite species, Neoseiulus cucumeris (Oudemans) and Neoseiulus barkeri Hughes, have been used to control the strawberry tarsonemid mite Phytonemus pallidus ssp. fragariae (Zimmerman) satisfactorily in field-grown strawberries in Finland [5]. Both species were also tested in greenhouse-grown strawberry against the strawberry tarsonemid mite and TSSM, but did not control TSSM satisfactorily [6].…”

Abstract. BACKGROUND:Chemical control of spider mites and thrips in everbearer strawberry is difficult as few efficient chemicals are available and residues represent a risk. In the north the success of biocontrol of mites and thrips in open fields compared with tunnels needs to be evaluated. OBJECTIVES: To investigate the need for control of spider mites and thrips and evaluate the effectiveness of biological control agents in everbearer strawberry. METHODS: Similar experimental plots, in a tunnel and an open field, planted with three everbearer strawberry varieties were arranged to compare the effect of introductions of the spider mite predator Phytoseiulus persimilis and releases of the generalist predatory mites Neoseiulus cucumeris and Neoseiulus barkeri and a predatory bug, Orius majusculus. Several sampling methods were used to evaluate mite and thrips populations. RESULTS: Phytoseiulus persimilis was successful against spider mites. Naturally occurring cecidomyiid and staphylinid predators affected control positively. Thrips damage remained mostly tolerable. The dominant thrips species were Thrips major, Thrips atratus, Thrips vulgatissimus and Frankliniella intonsa. Thrips numbers in the beating tray samples correlated with thrips damage to berries. CONCLUSIONS: Predatory mites were effective in controlling spider mites in an open field and a tunnel. The need for thrips control depended on the strawberry variety. Naturally occurring predators contributed to the control of spider mites and thrips.
