“…In one test 36% of the predators had become symptomatic and 38% of the predators tested positive; in the second test 70% of the predators had become symptomatic and 61% of the predators tested positive. Moreover a significant negative correlation was found between the proportion of predators being attracted to herbivore induced plant volatiles and the proportion of PCR-positive samples (Gols et al 2007). By using this molecular detection method it was demonstrated that A. phytoseiuli is rather widespread among European populations of P. persimilis.…”

“…Thus, the only well documented case of a bacterial disease in phytoseiid mites represents the infection of P. persimilis with Acaricomes phytoseiuli (Schütte 2006;Schütte et al 1995Schütte et al , 1996Schütte et al , 1998Schütte et al , 2006aSchütte et al , b, 2008aDicke et al 2000;Pukall et al 2006;Gols et al 2007). During the early 1990s the first conspicuous disease symptom that became obvious was a behavioural change (Schütte et al 1995;Dicke et al 2000).…”

“…It appears that the new genus Acaricomes is closely related to the genus Arthrobacter. Recently a specific and reliable PCR-test has been developed for the detection of A. phytoseiuli (Gols et al 2007). In two validation tests healthy female P. persimilis were previously infected with A. phytoseiuli.…”

“…Verified and potential pathogens have been reported in phytoseiid mites collected from the field (Furtado et al 1996), from those currently mass-produced for biological pest control (Beerling and van der Geest 1991a, b;Bjørnson and Keddie 2000;Gols et al 2007) and from laboratory populations (Hess and Hoy 1982;Becnel et al 2002;Schütte et al 2008b;Pukall et al 2006;Gols et al 2007). For the latter two cases it could not be determined whether the entities originated from field-collected natural enemies or arose in mass-rearing systems as a result of intense and continuous rearing under laboratory conditions.…”

Several species of phytoseiid mites (Acari: Phytoseiidae), including species of the genera Amblyseius, Galendromus, Metaseiulus, Neoseiulus, Phytoseiulus and Typhlodromus, are currently reared for biological control of various crop pests and/or as model organisms for the study of predator-prey interactions. Pathogen-free phytoseiid mites are important to obtain high efficacy in biological pest control and to get reliable data in mite research, as pathogens may affect the performance of their host or alter their reproduction and behaviour. Potential and verified pathogens have been reported for phytoseiid mites during the past 25 years. The present review provides an overview, including potential pathogens with unknown host effects (17 reports), endosymbiotic Wolbachia (seven reports), other bacteria (including Cardinium and Spiroplasma) (four reports), cases of unidentified diseases (three reports) and cases of verified pathogens (six reports). From the latter group four reports refer to Microsporidia, one to a fungus and one to a bacterium. Only five entities have been studied in detail, including Wolbachia infecting seven predatory mite species, other endosymbiotic bacteria infecting Metaseiulus (Galendromus, Typhlodromus) occidentalis (Nesbitt), the bacterium Acaricomes phytoseiuli infecting Phytoseiulus persimilis AthiasHenriot, the microsporidium Microsporidium phytoseiuli infecting P. persimilis and the microsporidium Oligosproridium occidentalis infecting M. occidentalis. In four cases (Wolbachia, A. phytoseiuli, M. phytoseiuli and O. occidentalis) an infection may be connected with fitness costs of the host. Moreover, infection is not always readily visible as no obvious gross symptoms are present. Monitoring of these entities on a routine and continuous basis should therefore get more attention, especially in commercial mass-production. Special attention should be paid to field-collected mites before introduction into the laboratory or mass rearing, and to mites that are exchanged among rearing facilities. However, at present general pathogen monitoring is not yet practical as effects of many entities are unknown. More research effort is needed concerning verified and potential pathogens of commercially reared arthropods and those used as model organisms in research.

“…Acaricomes phytoseiuli, is a bacterium reported in association with Phytoseiulus persimilis. The infection with A. phytoseiuli affected the predator efficiency against the spider mite prey (Gols et al 2007). Wu and Hoy (2012) detected the bacterium Wolbachia in Metaseiulus occidentalis and some other phytoseiid predators.…”
