“…T. ludeni, which has no diapause ability, overwintered on weeds, especially on rosettes of goldenrod, S. altissima, which began to emerge from the ground in December. Takafuji (1980) also observed that T. ludeni overwintered on rosettes of goldenrod. Just after the kudzu vine flushed in early May, spider mites were observed on kudzu vine leaves, so spider mite females may migrate from herbaceous weeds to newly flushed kudzu vine leaves.…”

“…This is due to difficulties in identification by morphological characters either under a dissecting microscope or under a phase-contrast microscope because of their tiny body sizes and subtle differences of morphology. The pioneer work of Takafuji (1980) focused on analyzing the relationships between three phytophagous mite species and their predators on goldenrod, which is an alien weed. Phytophagous mites that belong to different families were chosen for this study because they were easily distinguishable under a dissecting microscope.…”

Populations of spider mites were sampled from kudzu vine Pueraria lobata (Willd.) from 1997 to 1999 at two study sites in Ibaraki, central Japan. Of the five spider mite species sampled, Tetranychus pueraricola Ehara and Gotoh was the most abundant (accounting for 75.6-96.9% of mites) in each of the three years. The next most abundant species were T. ludeni Zacher (0.8-19.0%), T. parakanzawai Ehara (1.1-9.7%) and T. piercei McGregor (3.1%), but their density and species richness varied from year to year and from site to site. The populations peaked in June and/or September-October. Predators associated with spider mite populations were phytoseiid mites such as Amblyseius tsugawai Ehara, Phytoseius nipponicus Ehara and Neoseiulus womersleyi (Schicha), Scolothrips takahashii Priesner, Oligota spp., Feltiella spp. and stigmaeid mites such as Agistemus exsertus Gonzalez and A. terminalis (Quayle), which were well synchronized with spider mite density. Overwintered females began to appear and oviposit on some herbaceous weeds growing at the study sites in early April. Spider mites appeared on kudzu vine leaves in early May just after flushing. Most colonies (defined as areas surrounded with silky spider mite threads) had only one species but a small percentage had two or three species.

Previous observations in the tea fields of central Shizuoka Prefecture (Hamamura, 1986) and a field survey in undisturbed environments (eg., Takafuji, 1980) showed that phyoseiids are generally most abundant around this season. Two tea fields at Haruno were situated at a mountainous area and the others in lowlands.…”

“…Spider mites living in moderatetemperature regions show bimodal population peaks with one peak occurring in early summer and the other peak occurring in autumn. The low population density between the two peaks is caused by various factors including (1) deterioration of host plant quality as a result of feeding damage of mites, (2) plant aging and plant senescence by hot weather in summer (Takafuji 1980;Takafuji and Kamibayashi 1984;Gotoh 1997;Gotoh and Kubota 1997), (3) increased amounts of secondary compounds at flowering time in July (Gotoh and Gomi 2000) and (4) predation (Kitashima and Gotoh 2003). The mite populations increase again and form autumn peaks after the relaxation of these pressures, e.g., by a flush of new leaves or by decreased levels of secondary compounds and/or predators.…”

Does the Number of Diapausing Eggs Laid on Bark Affect the Population Dynamics of the Spider Mite Panonychus mori?

et al. 2006

We studied the relationship between number of diapausing eggs produced by the spider mite Panonychus mori and the subsequent population trend for a period of 3 years. Panonychus mori showed a single population density peak on its host plant moonseed, Cocculus trilobus. The position and height of this peak were correlated with the density of diapausing eggs around the moonseed leaf buds produced the winter before. In 1994 the density of diapausing eggs measured in February was 4.3/bud, which was 6-14 times higher than the density of diapausing eggs for the same period in 1995 (0.3/bud) and 1996 (0.7/bud). The subsequent population density peak in 1994 occurred in mid June and was about 2.5 times higher than the peaks in 1995 and 1996, which both occurred early September. Thus, the present study showed a positive correlation between the density of diapausing eggs on the host plant and the start and the extend of the population increase the next growing season. Predators associated with the spider mite population were phytoseiid mites, especially Amblyseius eharai was well synchronized with the spider mite density in 1994. Field observations revealed that P. mori produced diapausing eggs in response to short photoperiod in early October each year, which corresponded with the timing predicted by the critical photoperiod around 13 h at 18 degrees C, as assessed in laboratory trials. Diapause ended by early April when egg hatchability attained about 50% and eggs took 9 days to hatch at 25 degrees C and a 16L:8D photoperiod. Hatching in early April was twice faster than in late February.
