| brevipalpus californicus, b. obovatus, b. phoenicis, and b. lewisi (acari: tenuipalpidae): a review of their biology, feeding injury and economic importance. | the genus brevipalpus includes most of the economically important species of tenuipalpidae. many brevipalpus species reproduce by theletokous parthenogenesis while other species reproduce by male fertilization of female eggs. previous researchers have determined that brevipalpus californicus (banks), b. obovatus donnadieu, and b. phoenicis (geijskes) females were haploid with two chromosomes. the life cycle and developmental times for these three species are reviewed. longevity of each brevipalp ... | 2003 | 14756411 |
| detection of 'candidatus cardinium' bacteria from the haploid host brevipalpus californicus (acari: tenuipalpidae) and effect on the host. | brevipalpus californicus (banks) was infected with 'candidatus cardinium' bacteria (cardinium). tetracycline-treated females produced many male progeny even though untreated females produced only female progeny. b. californicus appears to be feminized by cardinium. the values for net reproduction rate (r0), generation time (t) and intrinsic rate of natural increase (r(m)) calculated for b. californicus were 7.48/day, 31.45 days and 0.064/day, respectively. the comparison of infected females with ... | 2005 | 16180076 |
| species composition and abundance of brevipalpus spp. on different citrus species in mexican orchards. | we studied the abundance of brevipalpus spp. in citrus orchards in the mexican states of yucatan, quintana roo and campeche. mites were collected from 100 trees containing a mixture of citrus species where sweet orange was always the main species. eight collections were made at each location from february 2010 to february 2011. mites from the genus brevipalpus were separated from other mites surveyed and their abundance and relationships with the different citrus species were quantified througho ... | 2013 | 23949863 |
| [plant rhabdoviruses with bipartite genomes]. | members of the family rhabdoviridae (order mononegavirales) have a broad range of hosts, including humans, livestock, fish, plants, and invertebrates. they have a nonsegmented negative-sense rna as the genome. orchid fleck virus (ofv) is distributed world-wide on several orchid plants and transmitted by the false spider mite, brevipalpus californicus. based on its virions morphology and cytopathic effects in the infected cells, ofv was tentatively placed as unassigned plant rhabdoviruses in the ... | 2013 | 25366049 |
| orchid fleck virus: brevipalpus californicus mite transmission, biological properties and genome structure. | orchid fleck virus (ofv) causes necrotic or chlorotic ring spots and fleck symptoms in many orchid species world-wide. the virus has non-enveloped, bacilliform particles of about 40 nm x 100-150 nm and is sap-transmissible to several plant species. ofv is transmitted by the mite brevipalpus californicus (banks) in a persistent manner and efficiently transmitted by both adults and nymphs, but not by larvae. viruliferous mites retain their infectivity for 3 weeks on a virus-immune host. the genome ... | 2003 | 14756418 |
| morphological observations on brevipalpus phoenicis (acari: tenuipalpidae) including comparisons with b. californicus and b. obovatus. | the genus brevipalpus has over 300 species worldwide. the three most important agricultural pest species in the genus, brevipalpus californicus (banks), b. obovatus donnadieu, and b. phoenicis (geijskes), have been consistently confused and misidentified for more than 50 years. the present study provides a discussion of the characters and character states used to separate these mites. low-temperature scanning electron microscopy and traditional light microscopy techniques were used to illustrate ... | 2003 | 14756413 |
| host plants of brevipalpus californicus, b. obovatus, and b. phoenicis (acari: tenuipalpidae) and their potential involvement in the spread of viral diseases vectored by these mites. | the family tenuipalpidae has over 622 species in 30 genera described worldwide. a total of 928 plant species in 513 genera within 139 families are recorded hosts of one or more of the following species: brevipalpus californicus (banks), b. obovatus donnadieu, and b. phoenicis (geijskes). b. californicus has 316 plant species reported as hosts compared with 451 and 486 host plants for b. obovatus and b. phoenicis, respectively. there are 67 genera of plants within 33 families that are reported ho ... | 2003 | 14756412 |
