resistance to fiji disease in sugar cane: role of cultivar preference by planthopper vector perkinsiella saccharicida (homoptera: delphacidae).	fiji disease (fd) of sugar cane caused by fiji disease virus (fdv) is transmitted by the planthopper perkinsiella saccharicida kirkaldy (hemiptera delphacidae). fd is effectively managed by using resistant cultivars, but whether the resistance is for the vector or for the virus is unknown. this knowledge would help develop a rapid and reliable glasshouse-based screening method for disease resistance. sugar cane cultivars resistant, intermediate, and susceptible to fd were screened in a glasshous ...	2003	12650358
variation in acquisition of fiji disease virus by perkinsiella saccharicida (hemiptera: delphacidae).	fiji leaf gall, caused the fiji disease virus (genus fijivirus, family reoviridae, fdv), is a serious disease of sugarcane, saccharum officinarum l., in australia and several other asia-pacific countries. in australia fdv is transmitted only by the planthopper perkinsiella saccharicida kirkaldy (hemiptera: delphacidae), in a propagative manner. successful transmission of fdv by single planthoppers confined to individual virus free plants is highly variable, even under controlled conditions. the ...	2008	18330111
in vitro rearing of perkinsiella saccharicida and the use of leaf segments to assay fiji disease virus transmission.	fiji leaf gall (flg) is caused by the reovirus, fiji disease virus (fdv), which is transmitted to sugarcane by planthoppers of the genus perkinsiella. low vector transmission rates and slow disease symptom development make experimentation within the fdv-perkinsiella-sugarcane system inherently difficult. a laboratory-based technique was devised to rear the vector using sugarcane leaves as a food source. planthoppers were reared on sugarcane leaf segments embedded in agarose enclosed within plast ...	2008	18943257
variable infection frequency and high diversity of multiple strains of wolbachia pipientis in perkinsiella planthoppers.	this survey of wolbachia infections in populations of the planthoppers perkinsiella saccharicida and perkinsiella vitiensis revealed variable frequencies, low-titer infections, and high phylogenetic diversities of strains. these observations add to the growing realization that wolbachia infections may be extremely common within invertebrates and yet occur infrequently within populations and at low titer within individuals.	2011	21278277
Identification of yeast associated with the planthopper, Perkinsiella saccharicida: potential applications for Fiji leaf gall control.	Yeasts associate with numerous insects, and they can assist the metabolic processes within their hosts. Two distinct yeasts were identified by PCR within the planthopper Perkinsiella saccharicida, the vector of Fiji disease virus to sugarcane. The utility of both microbes for potential paratransgenic approaches to control Fiji leaf gall (FLG) was assessed. Phylogenetic analysis showed one of the microbes is related to yeast-like symbionts from the planthoppers: Laodelphax striatellus, Nilaparvat ...	2011	21850475
electron microscopic and physicochemical analysis of a reo-like virus of the planthopper peregrinus maidis.	a virus, determined to be a member of the reoviridae, was found naturally infecting colonies of peregrinus maidis, the maize planthopper. the virus, referred to as peregrinus maidis-virus (pgmv), was found by electron microscopy throughout all p. maidis tissues examined, including salivary glands, testes, ovaries, and intestines. the virus particles were associated with fibrillar viroplasmic inclusions in the cytoplasm, of a type characteristic of the reoviridae. the particles, purified from p. ...	2011	3182234
