It has been imported and established in Australia and New Zealand in classical biological control programs for the control of mites in apple and peach orchards (Readshaw 1975; Field 1978) buy flomax 0.2 mg low price prostate cancer under 50. Between 1970 and early 1981, at least 470 papers were published on the Phytoseiidae (Tanigoshi 1982) and between 1960 and 1994, more than 420 papers were published on M. The number of chromosomes (3 and 6 in males and females, respectively) and the genetic system of M. Whether this unusual genetic system is inXuenced by the microbial associates (Wolbachia or Cardinium) of M. Whether pesticide-resistant microbial symbionts are associated with these resistances also remains unknown, but many soil microorganisms have been documented to degrade pesticides (Felsot 1989) and microbial gut symbionts of a tephritid have been implicated in the pesticide resistance of its host (Boush and Matsumura 1967). Because mitochondrial organelles are derived from endosymbiotic bacteria, these unusual features will be discussed brieXy below. Diseases of Mites and Ticks 331 Despite this extensive research conducted over the past 60 years, until recently we knew little about the microbial associates of M. We adhere to the term symbiosis in its original deWnition of organisms living together, usu- ally in close association with one another, to the beneWt of at least one organism, with the partners referred to as symbionts. Infection by a particular bacterium may be beneWcial to a host under some circumstances but harmful in other hosts or environ- ments. At one extreme are the ancient symbionts that live in specialized bacteriomes (host organs or cells specialized for housing the symbionts) and are required by their hosts. Facultative symbionts may not reside exclusively in specialized organs and are not strictly necessary for host survival. Pathogenic symbionts may be pathogens at all times, or they may become pathogenic only when the host immune system allows the microorganism to increase in density. The goal of this review is to discuss what we know about the microbial associates (whether they are called endosymbionts, mutualists, pathogens, or have an unknown rela- tionship) of this important predator and provide a brief overview of what can be learned as new methods are applied to understanding these relationships. Then we will discuss what we know (and don t) about the microbial endosymbionts of M. In addition, we will discuss some of the methodological issues restricting our understanding of these relationships.
