“…This option may provide some insights into new aspects of phytoseiid distribution on the tree. Kawashima and Amano (2004) studied the seasonal occurrence of phytoseiid mites on the deciduous yedo hornbeam tree (Carpinus tschonoskii Maxim.) and compared the numbers of mites caught by Phyto traps on twigs with the numbers inhabiting galls induced by an eriophyid mite (Acalitus sp.)…”

The Phyto trap is an artificial microstructure that permits the easy collection of live predacious phytoseiid mites in the field. Neoseiulus californicus is a well-established indigenous phytoseiid mite in Japanese pear tree orchards in Japan. We examined whether or not the population size of N. californicus on Japanese pear trees can be estimated using Phyto traps attached to twigs in two Japanese pear orchards. The results suggest that the density of a prey mite, Tetranychus kanzawai, on leaves influenced the number of N. californicus trapped by the Phyto traps. When the density of T. kanzawai was high on the leaves, many N. californicus were observed on the leaves and the pattern of density change synchronized between T. kanzawai and N. californicus. Under this condition, no N. californicus were found in the Phyto traps. On the other hand, when the density of T. kanzawai was low on the leaves, N. californicus were found in the Phyto traps as well as on the leaves. The number of N. californicus collected by the Phyto traps also increased as the extent of leaf withering increased, and reached a peak after leaf fall was complete. This suggests that the movement of N. californicus on the pear trees during leaf-fall season can be elucidated in some detail by using the Phyto trap. The survey by the Phyto trap attached to twigs can eventually clarify the population fluctuation and movement of N. californicus on trees that are been overlooked in the investigation of the leaves alone.

“…The timing of movement into overwintering sites of this species was also studied by using Phyto traps attached to twigs on the deciduous tree, C. tschonoskii, on which females began to enter the traps in late October and had completed movement by early December (Kawashima and Amano 2004). The results of the present study indicate that T. vulgaris females were active on the trees until the time when the pear trees had completely defoliated.…”

“…For example, Typhlodromus vulgaris adult females were observed to overwinter in Phyto traps attached to twigs of the deciduous yedo hornbeam tree (Carpinus tschonoskii Maxim.) in Chiba Prefecture, central Japan (Kawashima and Amano 2004). On the other hand, Neoseiulus californicus (McGregor) did not overwinter in Phyto traps attached to twigs of Japanese pear trees surveyed in another area of Chiba Prefecture (Kawashima et al 2006), suggesting a different overwintering strategy of this mite species.…”

“…Phyto traps have been used to monitor the abundance and population fluctuations of phytoseiid mites on trees (Koike et al 2000;Kawashima and Amano 2004;Kawashima et al 2006), and it can also be used as a means of tracing mite movement into overwintering sites. For example, Typhlodromus vulgaris adult females were observed to overwinter in Phyto traps attached to twigs of the deciduous yedo hornbeam tree (Carpinus tschonoskii Maxim.)…”

Phyto traps were attached to twigs, main branches and trunks of Japanese pear trees in central Japan in autumn of 2004, to evaluate the effectiveness of the trap as a tool to study overwintering phenology of arboreal phytoseiid mites. A subset of the traps was inspected and replaced at two-weeks intervals ("short-term Phyto trap"), in order to evaluate movement of phytoseiid mites on the trees in a short-term. The remaining traps were left undisturbed and collected monthly from January to May 2005 ("long-term Phyto trap"), to know what species overwinter in the traps and when they leave them. Most phytoseiid mites were collected in the traps on twigs. The most abundant phytoseiid species was Typhlodromus vulgaris Ehara. In the short-term traps on twigs, adult females and males of T. vulgaris were collected until mid-November 2004, when the pear trees became completely defoliated, but few mites were collected from December to April. On the other hand, adult females of T. vulgaris were abundant in the long-term traps on twigs sampled from January to April, but other stages of mites were never collected. These results indicate that T. vulgaris had moved to the long-term traps by late November, and that only adult females had overwintered in the traps. These females began to move and reproduce in early May. By that time immature developmental stages of T. vulgaris were also recorded in the short- and long-term Phyto traps. Our results confirmed that the Phyto trap was a useful tool for estimating overwintering phenology of phytoseiid mites on trees.

“…The establishment of phytoseiid population on apple trees in this study was dependent upon the feeding preferences to phytophagous mites on apple trees, the interaction among phytoseiid species, and the sensitivities of the mites to fungicides. T. vulgaris prefers feeding eryophyid mites (Kawashima and Amano, 2004). In addition, T. vulgaris develops faster on apple trees (Funayama and Takahashi, 1993).…”

Population dynamics of phytophagous and phytoseiid mites in a newly planted apple orchard were investigated for the consecutive 5 years just after the stop of insecticide applications, to verify the effect of the phytoseiids on the dominance and density of phytophagous mite species. Phytoseiid mites were typically most abundant in autumn from 2005 to 2008, except in 2009 when there were two marked peaks. Although 10 phytoseiid mite species were collected over the five-year study period, species abundance and composition changed gradually over time. The phytophagous mites were most abundant in the autumn of 2005, but the timing of peak occurrence and density changed as the study progressed. Changes in the abundance and species composition of the phytoseiid mite communities, Tetranychus urticae abundance was not suppressed by the phytoseiid mites. Although Panonychus ulmi was suppressed to insecticide application, P. ulmi may affect T. urticae abundance under a no-insecticide regime. Finally, T. urticae disappeared and P. ulmi and Aculus schlechtendali decreased in abundance. Although not marked, Typhlodromus vulgaris played a key role in affecting the stability of mite communities in apple orchards when no insecticides were applied.
