Despite economic importance of Tetranychidae, knowledge regarding diversity of spider mites in the Balkan Peninsula and Southeast Europe is incomplete, especially in protected natural areas. This study presents diversity of spider mites (Acari: Tetranychidae) collected over five growing seasons at 296 locations in 38 protected natural areas of Serbia. A total of 31 spider mite species were found, 10 from Bryobiinae and 21 from Tetranychinae. The species Eotetranychus fagi Zacher was recorded as new to Serbia and this record was also the first one for Southeast Europe. Spider mites were found on host plants in five basic types as well as many subtypes of terrestrial habitats, with woodland as the most dominant one. A total of 151 plant species from 44 families were recorded as hosts for spider mites including new world records: 60 new hosts for family Tetranychidae and 41 new hosts for 21 spider mite species. Host plants from Rosaceae family harbored the highest number of spider mite species (16). A considerable number of species was found on host plants from the families Betulaceae (11), Asteraceae (10) and Sapindaceae (10). Two cosmopolitan spider mites, Tetranychus urticae Koch and Tetranychus turkestani Ugarov & Nikolskii, were clearly distinguished with 67 (7 new) and 43 (13 new) recorded host species, respectively; among newly recorded hosts for Tetranychidae family, these two mite species were found on 27 and 12 hosts, respectively. After the two most common species, the most striking was the presence of Bryobia praetiosa Koch with 24 (4 new) recorded host plants, followed by Amphitetranychus viennensis (Zacher), Eotetranychus carpini (Oudemans) and Bryobia rubrioculus (Scheuten), with 21 (7 new), 20 (6 new) and 16 (2 new) hosts, respectively. The remaining tetranychids were found on 1–9 host plant species. This study provided the first insight into diversity of tetranychids in Serbian protected areas. Further research in this field should focus on mites from host plants representative of specific areas and habitats, including endangered, endemic and relict species.

The Family

Eighteen predatory mite species of the family Phytoseiidae are reported from three sites of the Cerrado ecosystem in the State of S o Paulo, southeastern Brazil, on seven plant species of the family Myrtaceae. This paper provides a list of those species and compares relevant morphological characteristics of the specimens collected with those of the original descriptions and/ or redescriptions of the corresponding species. A key is provided to help in the separation of the species mentioned in the paper. Some of the species collected have been reported as common predators on dominant crops in the region where the work was done. Their occurrence on Myrtaceae plants found naturally in the Cerrado ecosystem indicates that those plants could represent important reservoirs of those predators.

Tetranychus Ludeni

Seven spider mite species were recorded for the first time in Serbia: Bryobia macedonica Hatzinikolis & Panou, 1996 and Bryobia querci Hatzinikolis & Panou, 1997 from Bryobiinae, and Eutetranychus orientalis Klein, 1936; Oligonychus bicolor Banks, 1894; Oligonychus platani McGregor, 1950 Tetranychus canadensis McGregor, 1950 and Tetranychus ludeni Zacher, 1913 from Tetranychinae. Together with previously reported data, these findings raise the number of known tetranychid species in Serbia to 44, the second highest number of spider mite species recorded in the Balkan countries. The records of O. bicolor and T. canadensis are also the first ones on the Balkan Peninsula. The most frequent species were T. ludeni and E. orientalis, found in 24 and 13 out of 57 sampling locations. Spider mites were recorded on host plants in four basic habitat types, but predominantly in cultivated habitats and woodlands. A total of 27 plant species from nine families were recorded as hosts for newly recorded spider mites, including 12 plant species as new hosts for four tetranychids, and three plant species as new hosts for the family Tetranychidae. Plant family Rosaceae had the highest number of new hosts (7) and harbored the highest number of spider mite species (5). Tetranychus ludeni had the highest number of host plants (11) with two plant species as its new hosts. Oligonychus bicolor was found on eight host plants including five new hosts for this species and one new host for the family Tetranychidae. The other two new hosts for the family Tetranychidae harbored O. platani and B. querci, respectively. Symptoms of heavy infestations by E. orientalis and T. ludeni were recorded on host plants in several locations.

The predatory mite Neoseiulus californicus (McGregor) has characteristics of both type II specialist predatory mites and type III generalist predatory mites. N. californicus prefers Tetranychid mites as food, but will also consume other mite species, small insects, such as thrips, and even pollen when the primary prey is unavailable. N. californicus is often used to control the twospotted spider mite, Tetranychus urticae Koch, and other phytophagous mites on various crops in temperate and subtropical regions around the world.  This document is EENY-359, one of a series of the Entomology and Nematology Department, UF/IFAS Extension.

In this study, we report on the compatibility of two commercially available predatory mites, Neoseiulus californicus and Phytoseiulus persimilis, with three miticides used in greenhouse production systems to control the twospotted spider mite, Tetranychus urticae. We determined the lethal effects of the miticides chlorfenapyr, spiromesifen, and bifenazate to both predatory mite species 24 hours after exposure to spray applications in petri dishes. Two rates of chlorfenapyr (0.40 and 0.81 mL/2-L) and spiromesifen (0.15 and 0.31 mL·L–1), and one rate of bifenazate (0.62 mL·L–1) were used. All rates were based on the manufacturer label recommendations for twospotted spider mite. Both rates of chlorfenapyr and spiromesifen, and the single rate of bifenazate were not harmful to N. californicus with percent live mite values ≥85% for chlorfenapyr and ≥95% for spiromesifen, and 93% for bifenazate. However, these same miticides were substantially toxic to P. persimilis with percent live mite values of ≤63% for all the miticides tested. Based on the results of this study, the miticides chlorfenapyr, spiromesifen, and bifenazate are compatible with N. californicus whereas these miticides are toxic to P. persimilis indicating a difference in susceptibility based on predatory mite species.

Direct Defence

AbstractPlants infested with the spider mite Tetranychus urticae Koch, may indirectly defend themselves by releasing volatiles that attract the predatory mite Phytoseiulus persimilis Athias-Henriot. Several plants from different plant families that varied in the level of spider mite acceptance were tested in an olfactometer. The predatory mites were significantly attracted to the spider mite-infested leaves of all test plant species. No differences in attractiveness of the infested plant leaves were found for predatory mites reared on spider mites on the different test plants or on lima bean. Thus, experience with the spider mite-induced plant volatiles did not affect the predatory mites. Jasmonic acid was applied to ginkgo leaves to induce a mimic of a spider mite-induced volatile blend, because the spider mites did not survive when incubated on ginkgo. The volatile blend induced in ginkgo by jasmonic acid was slightly attractive to predatory mites. Plants with a high degree of direct defence were thought to invest less in indirect defence than plants with a low degree of direct defence. However, plants that had a strong direct defence such as ginkgo and sweet pepper, did emit induced volatiles that attracted the predatory mite. This indicates that a combination of direct and indirect defence is to some extent compatible in plant species.

Despite the economic importance of spider mites (Acari: Tetranychidae), data on their biodiversity are scarce in some regions of Europe, such as Balkan Peninsula and particularly in Serbia. In this country, according to the Spider Mites Web database, only 17 spider mite species belonging to seven genera have been reported. This study provides a review of the Serbian literature dealing with spider mites species recorded in Serbia and presents results of a four-year faunistic survey in which spider mites were collected on cultivated plants and native vegetation throughout the country. In the survey, a total of 23 species were recorded, including six species new to Serbian acarofauna: Bryobia praetiosa, Eotetranychus aceri, E. fraxini, E. pruni, Panonychus citri and Tetranychus evansi. Together with previously reported data, it raises the number of known spider mite species in Serbia to 36. A total of 90 host plant species from 21 families that are favorable to spider mites were recorded in this study; there were 62 new host records for 20 spider mite species with 11 records of new plant species as hosts of spider mites. There were 63 new records for Serbia among host plant species, raising the number of Serbian hosts for tetranychid mites to 137. The spider mite species new to Serbian acarofauna were found on 17 newly recorded host plants from 11 families. A key to all known spider mites species from Serbia is provided.

Potential Biocontrol Agent

Spiny snout mite (Neomolgus capillatus) is a potential biocontrol agent for clover flea (Sminthurus viridis) a white clover pest on dairy farms in warmer and wetter parts of New Zealand In the 1990s this mite was introduced from Brittany France into Tasmania for clover flea control Results during the release programme were highly promising and subsequent anecdotal farmer reports indicate widespread decreases in damage As N capillatus is a predatory mite and already known to attack nontarget organisms habitat specificity will determine whether it could be introduced into New Zealand without risk to native insects To assess this pastures on nine of the original Tasmanian release farms and adjacent nontarget habitats ranging from bush wetlands eucalypt stands to sand dune country were sampled in April 2014 Litter samples were collected heat extracted and mite species identified Neomolgus capillatus was found at effective densities in pastures that had good clover cover Where present it displaced Bdellodes spp mites that are ineffective against clover flea No N capillatus were found in the nontarget habitats all of which lacked clover and contained other predatory mites including Bdellodes spp Therefore the preference by N capillatus for lush pastures makes it an excellent prospect for introduction as a biocontrol agent into clover flea prone regions of New Zealand

Study of morphological characters of Tetranychus macfarlanei Baker & Pritchard and Tetranychus malaysiensis Ehara revealed high similarity by comparing all the important characters in addition to the characters pointed out by Ehara to separate those two species. Molecular phylogeny of seven Indian populations of T. macfarlanei and one population of T. malaysiensis from Philippines along with few distantly related species of Tetranychus was attempted. High degree of similarity between these two species at mitochondrial COI gene (96%) as well as ITS2 (rDNA) (96–99%) region was evident. Based on both morphological features and molecular data, T. malaysiensis is proposed as a junior synonym of T. macfarlanei based on ICZN’s law of priority. Also more female characters are prompted in this study to distinctly discriminate T. macfarlanei from its most resembling species, Tetranychus ludeni Zacher. Tetranychus macfarlanei has emerged as a pest of several cultivated crop plants in India.
