“…Thirteen species were previously reported from Israel (Bolland et al 1998;Swirski et al 2002;Palevsky et al 2003) and three, namely T. evansi Baker and Pritchard, T. ludeni Zacher, and A. histricina are herein recorded from Israel for the first time. ITS2 sequences of twelve species are reported here for the first time.…”

ITS2 sequences as barcodes for identifying and analyzing spider mites (Acari: Tetranychidae)

et al. 2007

The use of DNA barcodes, short DNA sequences from a standardized region of the genome, has recently been proposed as a tool to facilitate species identification and discovery. Here we show that second internal transcribed spacer of nuclear ribosomal DNA (rDNA-ITS2) barcodes effectively discriminate among 16 species of spider mites (Acari: Tetranychidae) from Israel. The barcode sequences of each species were unambiguously distinguishable from all other species and formed distinct, nonoverlapping monophyletic groups in the maximum-parsimony tree. Sequence divergences were generally much greater between species than within them. Using a 0.02 (2%) threshold for species diagnosis in our data set, 14 out of 16 species recognized by morphological criteria would be accurately identified. The only exceptions involved the low divergence, 0.011-0.015 (1.1-1.5%), between Tetranychus urticae and Tetranychus turkestani, where speciation may have occurred only recently. Still, these species had fixed alternative rDNA-ITS2 variants, with five diagnostic nucleotide substitutions. As a result, we tentatively conclude that rDNA-ITS2 sequence barcodes may serve as an effective tool for the identification of spider mite species and can be applicable as a diagnostic tool for quarantine and other pest management activities and decision-making. We predict that our work, together with similar efforts, will provide in the future the platform for a uniform, accurate, practical and easy-to-use method of spider mite species identification.

“…Although the spider mites of Israel are poorly known, members of most tribes (except the Tenuipalpoidini) were recorded. These number about a dozen, of which most are pests (Avidov and Harpaz 1969;Dubitzki and Gerson 1987;Gerson 1986;Gerson et al 1983;Palevsky et al 2003). …”

“…During an intensive study of the old world date mite, Oligonychus afrasiaticus (McGregor), conducted in the SAV of Israel (Palevsky et al, 2003(Palevsky et al, , 2004(Palevsky et al, , 2005, E. palmatus was often also found. This afforded an opportunity to study the phenology of this lesser-known inhabitant of date palms and to determine its status as a date fruit pest.…”

The spider mite Eutetranychus palmatus Attiah feeds on various palms. The objectives of this study were: (1) to study the phenology of this little-known species and (2) to determine its status as a pest of date fruit. During a three year study (2001)(2002)(2003), infestations of E. palmatus on fruit strands began earlier than those of the pestiferous old world date mite, Oligonychus afrasiaticus (McGregor), but peak numbers of the latter were invariably much higher than those of E. palmatus. On fronds E. palmatus was observed from mid-winter throughout summer, its highest numbers being recorded from May to early June. Later, in July and August, E. palmatus populations declined. Oligonychus afrasiaticus was seldom found during winter and spring, but maintained small populations on the fronds in summer, concurrent with very large numbers on the fruit strands. Adult cumulative mite day levels of O. afrasiaticus (on fruit strands) were always considerably higher than those of E. palmatus, but on fronds the opposite was observed. Despite the relatively minor pest status of E. palmatus in comparison to O. afrasiaticus, growers who have experienced spider mite damage caused by high populations of E. palmatus very early in the season (April-May) are applying acaricides to treat this pest. The damage potential of E. palmatus is discussed and compared to that of O. afrasiaticus.
