Population survey of phytoseiid mites and spider mites on peach leaves and wild plants in Japanese peach orchard

A survey of phytoseiid mites associated with crops and wild plants on Lesvos Island was conducted. Of twenty three species collected the most abundant were the following: Phytoseius finitimus Ribaga sensu Denmark (30%), Euseius finlandicus (Oudemans) and Typhlodromus psyllakisi Swirski and Ragusa (26%), Typhlodromus athenas Swirski and Ragusa (19%), Typhlodromus cryptus Athias-Henriot, and Typhlodromus intercalaris Livshitz and Kuznetsov (15%). A new species, Typhlodromus sapphicus sp. n., collected on Tilia sp. is also described.

Amblyseius Andersoni

The basic biological characteristics of two species of predacious phytoseiid mites, Phytoseiulus persimilis and Amblyseius andersoni, were studied in the laboratory. The results showed that P. persimilis had a higher reproductive rate during a shorter oviposition period and produced more progeny than A. andersoni. Amblyseius andersoni is considered to be along-lived phytoseiid and its rate of predation on adult female spider mites was higher than that of P. persimilis. With both species, unmated females did not reproduce and consumed significantly fewer prey than mated females.

Production Practices

Abstract Changes in almond production practices have caused sixspotted thrips, Scolothrips sexmaculatus Pergande, and the coccinellid beetle, Stethorus punctum LeConte, to replace phytoseiid mites as the dominant predators of spider mites in California almonds. We conducted a series of field studies to evaluate nine commercially available adhesive traps for S. sexmaculatus and S. punctum and found that the yellow strip trap was the most effective, least expensive, and easy to use. At peak population levels, individual cards routinely caught >1,000 S. sexmaculatus and >100 S. punctum trap−1 week−1. We documented that larger traps collected more S. sexmaculatus, and more S. sexmaculatus per square area, suggesting that the trap surface was attractive. We determined the number of traps needed to have 50, 70, and 90% confidence that the averages of trap captures were within 10, 30, and 50% of the population mean. Two yellow strip traps per orchard provided 90% confidence that trap captures were within 50% of the population mean if there were an average of 16.0 S. sexmaculatus trap−1 week−1 or 7.9 S. punctum trap−1 week−1. Populations required to attain the same levels of confidence using four traps per orchard were 3.9 S. sexmaculatus and 2.9 S. punctum trap−1 week−1. We conclude that use of the yellow strip trap to monitor for natural enemies, in combination with leaf samples for spider mites, has the potential to improve integrated pest management programs for spider mites, and assist future research to understand the biology and phenology of both predator species.

Ipm Strategy

AbstractMany plant-dwelling mites reside on lower leaf surfaces. The biological impact of solar ultraviolet-B (UV-B) radiation on spider mites has been demonstrated over the last decade. Due to the serious problem of acaricide resistance in spider mites, the development of alternative control methods and establishment of an integrated pest management (IPM) strategy are urgently needed, especially for greenhouse horticultural crops such as strawberries. A physical control method for spider mites using UV-B lamps (UV-B method) has been established. Using the UV-B method, simultaneous control of spider mites and powdery mildew, a major disease, is possible, making it is a favorable IPM strategy. Here, I introduce general findings regarding the biological impact of UV radiation on spider mites and phytoseiid mites, useful natural enemies for biological control, over the last decade, including dose response, effective wavelengths, and photoreactivation. Moreover, I introduce the application of UV-B to spider mite control in strawberry greenhouses, including the possibility of concurrent use with biological control via phytoseiid mites, and discuss its possible contributions to IPM.

First Time

The taxonomic portion of this paper discusses 27 species of mites of the family Phytoseiidae known to occur on plants in Madagascar. Eight new species are described: Phytoseius (Phytoseius) betsiboka. Ph. (Pennaseius) onilahy, Amblyseius (Amblyseius) hova, A. (A.) ankaratrae, A. (A.) boina, A. (A.) sakalava, A. (A.) trichophilus and A. (Proprioseiopsis) tulearensis. The following species are recorded for the first time from the island: Typhlodromus (Typhloseiopsis) contiguus Chant, 1959, Phyloseius (Phytoseius) crinitus Swirski & Shechter, 1961, Ph. (Ph.) intermedius Evans & Macfarlane, 1961, Ph. (Pennaseius) hongkongensis Swirski & Shechter, 1961, Ph. (P.)amba Pritchard & Baker, 1962, Iphiseius (Iphiseius) degenerans (Berlese, 1889), I. (Trochoseius) gongylus Pritchard & Baker, 1962, Paraphytoseius multidentatus Swirski & Shechter, 1961, Amblyseius (Amblyseius) hima Pritchard & Baker, 1962, A. (A.) deleoni Muma & Denmark, 1970, A. (Proprioseiopsis) sundi Pritchard & Baker, 1962 and A. (P.) peltatus Van der Merwe, 1968. Additional descriptions are given for most of these species. The male of P. multidentatus is described for the first time. New distribution records are presented for the following species: Typhlodromus scytinus Chazeau, 1970, the T. (Anthoseius) gutierrezi-chazeaui group, Amblyseius (Amblyseius) masiaka Blommers & Chazeau, 1974, A. (A.) bibens Blommers, 1973, A. (A.) rotundus Blommers, 1973, A. (A.) brevipes Blommers, 1973 and A. (A.) tamatavensis Blommers, 1974. The simultaneous occurrence of spider mites and other small arthropods on the plants on which the phytoseiids were collected is noted. A final chapter summarizes the results of experiments devised to see whether the collected phytoseiid mites can be effectively predators of spider mites, i.e. of Tetranychus neocaledonicus André, 1933 and sometimes Oligonychus coffeae (Nietner, 1861). Most of these results were negative. Only, Typhlodromus contiguus, Amblyseius tulearensis and A. sundi can regulate population numbers of the first prey species under circumstances of low webbing and/or additional food. Iphiseius degenerans, and possibly Amblyseius rotundus, can control Oligonychus coffeae in their area of distribution.
