“…Low performance of predators has revealed the presence of pathogens. For reviews is referred to Schütte and Dicke (2008), Bjørnson (2008) and Hoy and Jeyaprakash (2008).

Abstract. An overview is given of diseases in mites, caused by infectious microorganisms. Many pathogens play an important role in the regulation of natural populations of mite populations and are for this reason subject of research on the feasibility to develop such pathogens to biological control agents. Several examples are given of successful application of pathogens for the control of mite pests, but also failures are discussed. Most studies concern fungal pathogens of tetranychids and eriophyids; some of these fungi are possible candidates for biological control agent of species of noxious mites. An interesting group of pathogens form the intracellular symbionts: bacteria that may cause unusual effects in their hosts, such as parthenogenesis, feminization, male killing and incompatibilities. This group of bacteria is present in many invertebrates species and are presently widely studied as new molecular techniques have become available that make detection of such symbionts possible. Attention is also given to quality control of beneficial mites that are being used in integrated control programs. Beneficial mites, as e.g. predatory mites, may also be infected by microorganisms (bacteria, viruses, microsporidia), resulting in poor performance of the predator. Prospects for the application of pathogens in IPM systems are discussed.

The predatory miteMetaseiulusoccidentalis: mitey small and mitey large genomes

Metaseiulus occidentalis is a representative of an important family of mites (Arthropoda: Chelicerata: Acari: Phytoseiidae) that are effective predators of pest mites in agricultural crops around the world. Like many arthropods, this mite contains multiple genomes, including the genomes of several microbial symbionts as well as its own mitochondrial and nuclear genomes. The mitochondrial genome is "mitey" large at 25 kb, due to duplication and triplication of genes. By contrast, the nuclear genome is "mitey" small at 88 Mb. This mite has a parahaploid genetic system, tolerates inbreeding, and has a haploid chromosome number of 3. This predator was genetically improved for use in agriculture by developing strains that lacked the ability to overwinter in diapause or were resistant to multiple pesticides, and can be genetically modified using recombinant DNA methods. Sequencing the nuclear genome would provide useful insights that could enhance genetic improvement programs that would result in improved pest management, could provide genes needed to resolve the evolutionary relationships of this family, and could serve as a model for understanding the evolution and genetics of chelicerate arthropod predators.

We determined the distribution of microbial endosymbionts as possible agents of parthenogenesis in Oribatida. We screened mites from 20 species of 14 families suspected to be parthenogenetic from the absence or rarity of males. Our research included parthenogenesis-inducing bacteria Wolbachia spp., Cardinium spp., Rickettsia spp., and additionally Arsenophonus, Spiroplasma and microsporidia that can also manipulate host reproduction. We detected the endosymbionts by PCR-based methods and transmission electron microscopy (TEM) observation of fixed and stained preparations of host cells. We detected Wolbachia only in one Oribatida species, Oppiella nova, by identifying Wolbachia genes using PCR. TEM observations confirmed infection by the endosymbiont in O. nova and its lack in other Oribatida species. Sequence analysis of hcpA and fbpA genes showed that the Wolbachia strain from O. nova was different from strains characterized in some insects, crustaceans (Isopoda), mites (Tetranychidae), springtails (Hexapoda) and roundworms (Nematoda). The analysis strongly suggested that the Wolbachia sp. strain found in O. nova did not belong to supergroups A, B, C, D, E, F, H or M. We found that the sequences of Wolbachia from O. nova were clearly distantly related to sequences from the bacteria of the other supergroups. This observation makes O. nova a unique Wolbachia host in terms of the distinction of the strain. The role of these micro-organisms in O. nova remains unknown and is an issue to investigate.
