Mitochondrial DNA and RAPD polymorphisms in the haploid mite Brevipalpus phoenicis (Acari: Tenuipalpidae)

Experimental and Applied Acarology, 2004
Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) is recognized as the vector of citrus leprosis virus that is a significant problem in several South American countries. Citrus leprosis has been reported from Florida in the past but no longer occurs on citrus in North America.

Coffee Ringspot Virus Vectored by Brevipalpus phoenicis (Acari: Tenuipalpidae) in Coffee

Experimental and Applied Acarology, 2003
Coffee ringspot is characterized by conspicuous ringspot symptoms on leaves, berries, and less frequently on twigs. It is caused by coffee ringspot virus (CoRSV), a short, bacilliform virus (40 nm x 100-110 nm). The virus is not seed borne and is transmitted by Brevipalpus phoenicis (Geijskes).

Demecology of the false spider mite, Brevipalpus phoenicis (Geijskes) (Acari, Tenuipalpidae)

Journal of Applied Entomology, 1996
Abstract:A life and fecundity table has been constructed forBrevipalpus phoenicis, a serious pest of plantation crops, and various demographic parameters have been calculated. Although this mite has been found to possess a low growth rate (rm= 0.127), it possesses high rates of survival even in its senescence. Under constant experimental conditions the

Varietal Screening Based on Demographic Parameters: Resistance of Tea to Brevipalpus phoenicis (Acari: Tenuipalpidae)

Environmental Entomology, 1995
Nest plant resistance to herbivores is usually measured by visual screening in the field, which is very expensive. We tested an alternative method using 26 varieties of tea, Camellia sinensis, selected from different geographical locations to screen for resistance against the red and black flat mite, Brevipalpus phoenicis (Geijskes); survival and ...

Susceptibility of Brevipalpus phoenicis to entomopathogenic fungi

Experimental and Applied Acarology, 2006
The pathogenicity of 52 isolates from several fungus species was studied for the false spider mite Brevipalpus phoenicis. In addition, the main stages during the course of infection by Hirsutella thompsonii, by far the most virulent pathogen, were studied by means of light and electron microscopy.

Reproductive performance of the mite Brevipalpus phoenicis (Geijskes, 1939) on citrus and coffee, using life table parameters [PDF]

Brazilian Journal of Biology, 2006
The flat-mite Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) is considered important in citrus (Citrus spp.) and coffee plants (Coffea spp.) in Brazil, and is known as the leprosis and coffee ring spot mite, as being a vector of the Citrus

Resistance to hexythiazox in Brevipalpus phoenicis (Acari: Tenuipalpidae) from Brazilian citrus

Experimental & Applied Acarology, 2002
The objective of this study was to collect baseline information for implementing an acaricide resistance management program of Brevipalpus phoenicis (Geijskes) to hexythiazox in Brazilian citrus groves. The egg susceptibility of B. phoenicis to hexythiazox was measured by a direct contact bioassay.
