“…The fungus may also survive unfavorable conditions in other manners. Klingen, Waersted, and Westrum (2008) showed that Neozygites floridana may survive cold winter periods in the form of hyphal bodies inside hibernating females of T.urticae.…”

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.

Tetranychus urticae (Koch) (Trombidiformes: Tetranychidae) is a cosmopolitan spider mite species that infests more than 900 species of plants, including commercial species. Tetranychus cinnabarinus (Boudreaux) is characterized by a red coloration, in contrast to the green-colored T. urticae. Both are occasionally found coexisting in warm environments, and, for that reason, they are considered by some to be synonyms. In this study, we identified specimens of the two morphospecies using optical and electron microscopy and amplification of a segment of the mitochondrial cytochrome oxidase I (COI) gene. Bioassays determined the level of susceptibility and survival of both morphospecies when they were infected with the entomopathogenic fungus Neozygites floridana (Weiser and Muma). For the evaluation of the susceptibility of these morphospecies to N. floridana, bioassays were conducted under conditions of 25 ± 2°C, 60 ± 5% relative humidity, and a 12:12-h photoperiod regime. From these bioassays, we found that T. cinnabarinus was less susceptible to N. floridana and that there is a higher level of fertility, survival, and development in the T. cinnabarinus than in the T. urticae mites. Within a mass rearing system, T. cinnabarinus appears be a more efficaceous functional food for predatory mites, such as Phytoseiulus persimilis (Athias-Henriot) (Mesostigmata: Phytoseiidae), than T. urticae to support rearing and release of biological agents for integrated pest management.
