“…Pre-and post-mow counts in 2018 were not correlated to the fall 2018 and spring 2019 cyclamen mite counts. Abamectin (Agri-Mek® SC) was applied at two of the three farms after the post-mow sampling, and its efficaciousness, causing 100% mortality in the laboratory (Zalom et al 2009;Fountain et al 2010), may have decoupled counts between samples taken before and after application. Cyclamen mite counts were correlated between samples collected in fall 2018, spring 2019, and pre-and post-mow 2019, and just one of three farms sprayed abamectin in spring 2019, a few weeks after sampling when counts were low.…”

Cyclamen mite, Phytonemus pallidus (Banks) (Acari: Tarsonemidae), is a pest of strawberry, Fragaria × ananassa Duchesne (Rosaceae), that injures new growth, resulting in damage to leaves and fruit. The primary source of cyclamen mite in strawberry is infested planting material, and damaged plants tend to occur in small, isolated patches in perennial production systems. In the present study, we determined through repeated sampling of strawberry plants in Ontario and Saskatchewan, Canada whether relative cyclamen mite population levels were stable in commercial fields and whether overwintering and field renovation (mowing) affected populations. In Ontario, cyclamen mite counts were significantly correlated for 66% (10 of 15) of the paired comparisons from six sampling dates in more than one year, indicating a relatively stable distribution of cyclamen mite patches in strawberry fields. Winter caused high mortality (100 times fewer mites in spring than fall) and mowing caused some mortality (10 times fewer mites post- than pre-mow). We found that more cyclamen mite motiles were extracted from plant material stored in ethanol and triple-washed than were extracted using Berlese funnels, although counts from leaves were correlated between methods. No cyclamen mites were found in Saskatchewan. Knowing that cyclamen mite patches are local and spread is negligible will facilitate targeted applications of controls.

“…Because they are not easily visible, early detection is arduous, and they are often discovered only when symptoms appear. Cyclamen mites live inside young folded leaves and flower buds, which shield them from most control methods, including non-systemic acaricides (Zhang 2003;Fitzgerald et al 2008;Hoy 2011). This species is mainly parthenogenetic, and females can lay an average of two eggs per day for a mean oviposition period of eight days (Easterbrook et al 2003;Alford 2007;Rostami et al 2018).…”

“…It is also banned in Canada as of 31 December 2016 (Gouvernement du Canada 2011). Since then, much research has aimed to identify other effective acaricides, but results among studies are variable and the acaricides studied only appear to provide partial control of this pest (Raudonis 2006;Gobin and Bangels 2008;Zalom et al 2009;Fountain et al 2010;Lafontaine et al 2011;Labanowska et al 2015). Therefore, finding an alternative to chemical control is essential.…”

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.

Cyclamen mite (Phytonemus pallidus) causes injury to new growth of strawberry plants and is difficult to control because it is protected by folded leaves and plant crowns. Since cyclamen mite is easily transferred from strawberry nurseries to fruiting fields, dipping transplants in biopesticides may reduce initial populations. However, cyclamen mite numbers at 1 and 3 months-after-planting and yield and cyclamen mite injury to fruit in the following season did not differ among transplants immersed for 30 sec in Captiva® Prime, EcoTrol® EC, Landscape Oil, SuffOil-X® or Kopa Insecticidal Soap or the untreated control. Cyclamen mite is primarily controlled with foliar applications of acaricides, but there are few registered products. In greenhouse experiments, fenazaquin and pyridaben reduced cyclamen mite numbers by more than 90% in new leaves compared to the control, similar to that of the standard abamectin. New leaf injury ratings were reduced from 1 on average (scale of 0-3; 0 = no injury) pre-application to 0.25-0.5 for fenazaquin, pyridaben, and abamectin-treated plants compared to increasing to 2 for control plants 2 weeks after application. Spiromesifen and chlorfenapyr reduced cyclamen mite numbers in folded leaves in one greenhouse experiment. In the field, all acaricides reduced cyclamen mite numbers by 90-99% at 2- and 6-weeks post-application and by 75-90% at 10 months post-application. Abamectin and pyridaben resulted in 0.5-1.0% of strawberries with cyclamen mite damage compared to 3.0% for the control. All acaricides except chlorfenapyr improved strawberry yield and size. Overall, fenazaquin, pyridaben and spiromesifen should help diversify the chemical toolbox for cyclamen mite in field strawberry.
