local phytochemical response of musa acuminata × balbisiana colla cv. 'bluggoe' (abb) to colonization by sternorrhyncha. | the interaction of two sternorrhyncha species, the banana aphid (pentalonia nigronervosa coquerel (hemiptera: aphididae, aphidinae)), vector of the banana bunchy top virus (bbtv), and the latania scale (hemiberlesia lataniae signoret (hemiptera: diaspididae, diaspidinae)) with musa acuminata × balbisiana colla (abb group) 'bluggoe' (musaceae) was investigated by a combination of conventional and spatially resolved analytical techniques, (1)h nmr, uhplc-ms, and matrix-free uv-laser desorption/ion ... | 2017 | 27839785 |
localization of banana bunchy top virus and cellular compartments in gut and salivary gland tissues of the aphid vector pentalonia nigronervosa. | banana bunchy top virus (bbtv) (nanoviridae: babuvirus) is transmitted by aphids of the genus pentalonia in a circulative manner. the cellular mechanisms by which bbtv translocates from the anterior midgut to the salivary gland epithelial tissues are not understood. here, we used multiple fluorescent markers to study the distribution and the cellular localization of early and late endosomes, macropinosomes, lysosomes, microtubules, actin filaments, and lipid raft subdomains in the gut and princi ... | 2016 | 25728903 |
a metagenomic approach from aphid's hemolymph sheds light on the potential roles of co-existing endosymbionts. | aphids are known to live in symbiosis with specific bacteria, called endosymbionts which can be classified as obligate or accessory. buchnera aphidicola is generally the only obligatory symbiont present in aphids, supplying essential nutrients that are missing in the plants phloem to its host. pentalonia nigronervosa is the main vector of the banana bunchy top virus, one of the most damageable viruses in banana. this aphid is carrying two symbionts: b. aphidicola (bpn) and wolbachia sp. (wpn). t ... | 2015 | 26667400 |
cryptic diversity and habitat partitioning in an economically important aphid species complex. | cardamom bushy dwarf virus (cbdv) is an aphid-borne nanovirus which infects large cardamom, amomum subulatum (zingiberaceae family), in the himalayan foothills of northeast india, nepal and bhutan. two aphid species have been reported to transmit cbdv, including pentalonia nigronervosa and micromyzus kalimpongensis (also described as pentalonia kalimpongensis). however, p. nigronervosa was recently split into two species which exhibit different host plant affiliations. whilst p. nigronervosa pri ... | 2015 | 25535945 |
combination of genomic and proteomic approaches to characterize the symbiotic population of the banana aphid (hemiptera: aphididae). | aphids are known to live in symbiosis with specific bacteria called endosymbionts that have positive or negative impacts on their hosts. in this study, six banana aphid (pentalonia nigronervosa coquerel) strains from various geographical origins (gabon, madagascar, and burundi) were screened to determine their symbiotic content, using complementary genomic (16s rdna sequencing and specific polymerase chain reaction) and proteomic (two-dimensional difference gel electrophoresis coupled with prote ... | 2014 | 24472200 |
localization, concentration, and transmission efficiency of banana bunchy top virus in four asexual lineages of pentalonia aphids. | banana bunchy top virus (bbtv) is the most destructive pathogenic virus of banana plants worldwide. the virus is transmitted in a circulative non-propagative manner by the banana aphid, pentalonia nigronervosa coquerel. in this work, we examined the localization, accumulation, and transmission efficiency of bbtv in four laboratory-established lineages of pentalonia aphids derived from four different host plants: taro (colocasia esculenta), heliconia (heliconia spp.), red ginger (alpinia purpurat ... | 2013 | 23435241 |
development of a test to assess the banana bunchy top virus transmissibility through direct analyze of its aphid vector pentalonia nigronervosa. | 2013 | 23875297 | |
lack of evidence for an interaction between buchnera groel and banana bunchy top virus (nanoviridae). | circulative plant viruses such as luteovirids and geminiviruses have been shown to bind to groel proteins produced by endosymbiotic bacteria harboured within hemipteran vectors. these interactions seem to prevent the degradation of the viral particles in the aphid's haemocoel. similarly to luteovirids and geminiviruses, banana bunchy top virus (bbtv), a member of the nanoviridae family, is transmitted in a persistent, circulative manner and can be detected in the haemolymph of the aphid vector, ... | 2013 | 23816604 |
development of agrobacterium-mediated transformation of highly valued hill banana cultivar virupakshi (aab) for resistance to bbtv disease. | one of the most severe viral diseases of hill banana is caused by banana bunchy top virus (bbtv), a nanovirus transmitted by the aphid pentalonia nigronervosa. in this study, we reported the agrobacterium-mediated transformation on a highly valued hill banana cultivar virupakshi (aab) for resistance to bbtv disease. the target of the rna interference (rnai) is the rep gene, encoded by the bbtv-dna1. in order to develop rnai construct targeting the bbtv rep gene, the full-length rep gene of 870 b ... | 2013 | 23184576 |
tropism, compartmentalization and retention of banana bunchy top virus (nanoviridae) in the aphid vector pentalonia nigronervosa. | plant viruses of the families luteoviridae and geminiviridae rely on hemipteran vectors for the infection of their hosts. several lines of evidence have revealed that these viruses are transmitted by competent vectors in a circulative manner, involving entry into the vector's body and the crossing of epithelial tissues forming the alimentary tract and the salivary glands. similar to luteovirids and geminiviruses, a third family of plant viruses, the family nanoviridae, have also been reported to ... | 2013 | 23015741 |
transgenic banana plants expressing small interfering rnas targeted against viral replication initiation gene display high-level resistance to banana bunchy top virus infection. | the banana aphid-transmitted banana bunchy top virus (bbtv) is the most destructive viral pathogen of bananas and plantains worldwide. lack of natural sources of resistance to bbtv has necessitated the exploitation of proven transgenic technologies for obtaining bbtv-resistant banana cultivars. in this study, we have explored the concept of using intron-hairpin-rna (ihprna) transcripts corresponding to viral master replication initiation protein (rep) to generate bbtv-resistant transgenic banana ... | 2012 | 22552945 |
banana bunchy top virus in sub-saharan africa: investigations on virus distribution and diversity. | banana bunchy top virus (bbtv) was first reported from sub-saharan africa (ssa) from democratic republic of congo (drc) in the 1950s, has become invasive and spread into 11 countries in the region. to determine the potential threat of bbtv to the production of bananas and plantains (musa spp.) in the sub-region, field surveys were conducted for the presence of banana bunchy top disease (bbtd) in the drc, angola, cameroon, gabon and malawi. using the dna-s and dna-r segments of the virus genome, ... | 2011 | 21549775 |
population distribution and density of pentalonia nigronervosa (hemiptera: aphididae) within banana mats: influence of plant age and height on sampling and management. | the banana aphid, pentalonia nigronervosa coquerel (hemiptera: aphididae), is the most economically important pest of banana (musa spp.) fields in hawaii. recently, there has been a concerted effort in hawaii to learn more about the biology and ecology of this pest. however, limited work has been directed at determining the distribution of p. nigronervosa in banana fields and developing an integrated pest management plan. therefore, a survey was conducted in banana fields throughout the hawaiian ... | 2011 | 21735915 |
a comparison of fitness characters of two host plant-based congeneric species of the banana aphid, pentalonia nigronervosa and p. caladii. | aphids and other phytophagous insects often show intra-specific variations in relation to host plant utilization. in several instances, intra-species variations lead to host-plant specialization. these are considered to be important source of speciation. in a recent study ( foottit rg et al. 2010 . zootaxa 2358: 25–38) two forms of the banana aphid, pentalonia nigronervosa f typica coquerel (hemiptera: aphididae) from banana hosts and p. nigronervosa f. caladii van der goot collected from zingib ... | 2010 | 20883136 |
immunofluorescence localisation of banana bunchy top virus (family nanoviridae) within the aphid vector, pentalonia nigronervosa, suggests a virus tropism distinct from aphid-transmitted luteoviruses. | we have applied immunocapture pcr and developed an immunofluorescence assay to specifically detect banana bunchy top virus (bbtv; family nanoviridae, genus babuvirus) within its aphid vector, pentalonia nigronervosa (hemiptera, aphididae). bbtv was localised using either monoclonal or polyclonal antibodies into the anterior midgut (stomach) and into specific cells forming the principal salivary glands. these results suggest a distinct path of virus translocation that likely differs from the one ... | 2010 | 21167229 |
aphid transmission of banana bunchy top virus to bananas after treatment with a bananacide. | field and laboratory studies were conducted to determine the impact of using a herbicide as a bananacide on aphid transmission of banana bunchy top virus (family nanoviridae, genus babuvirus, bbtv) to healthy banana (musa spp.) plants. bbtv-infected banana plants in a commercial orchard were treated with roundup weathermax herbicide. using polymerase chain reaction, the time after herbicide treatment that bbtv could no longer be detected in the infected plants was determined. the impact of the h ... | 2009 | 19449627 |
comparative susceptibility of two banana cultivars to banana bunchy top virus under laboratory and field environments. | field and laboratory experiments were carried out on the island of oahu, hi, to compare the susceptibility of the two most commonly grown banana (musa sp.) cultivars in the state ('dwarf brazilian' or santa catarina [locally known as dwarf apple] and 'williams') to the aphid-borne banana bunchy top virus (genus babuvirus, family nanoviridae, bbtv). several morphological and physiological features of the two cultivars were monitored to determine whether the banana aphid, pentalonia nigronervosa c ... | 2009 | 19610400 |
effect of temperature, vector life stage, and plant access period on transmission of banana bunchy top virus to banana. | the study of the transmission biology of insect-borne plant viruses is important to develop disease control practices. we characterized the transmission of a nanovirus, banana bunchy top virus (bbtv), by its aphid vector pentalonia nigronervosa coquerel (hemiptera, aphididae) with respect to temperature, vector life stage, and plant access time. adult aphids transmitted bbtv more efficiently than third instar nymphs at all temperatures tested. adult aphids transmitted the virus more efficiently ... | 2008 | 18944300 |
biology of pentalonia nigronervosa (hemiptera, aphididae) on banana using different rearing methods. | the banana aphid, pentalonia nigronervosa coquerel, is present worldwide where banana (musa spp.) is grown. it is the vector of banana bunchy top virus (nanoviridae, babuvirus), the etiological agent of banana bunchy top disease, currently the most important constraint for banana producers in hawaii. p. nigronervosa is not well studied, and effects of temperature on its growth and reproduction are unknown. we studied the longevity and fecundity of one clone of banana aphid on different types of ... | 2007 | 17349115 |
within-plant distribution and binomial sampling of pentalonia nigronervosa (hemiptera: aphididae) on banana. | the banana aphid, pentalonia nigronervosa coquerel (hemiptera: aphididae), infests banana (musa spp.) worldwide. pentalonia nigronervosa is the vector of banana bunchy top virus (family nanoviridae, genus babuvirus) the etiological agent of banana bunchy top disease (bbtd). bbtd is currently the most serious problem affecting banana in hawaii. despite the importance of this vector species, little is known about its biology or ecology. there are also no sampling plans available for p. nigronervos ... | 2006 | 17195692 |
movement and transmission of banana bunchy top virus dna component one in bananas. | the systemic movement and replication of banana bunchy top virus (bbtv) dna component one were investigated. strand-specific rna probes and pcr were used to indicate the presence of the virus in various parts of infected banana plants during infection on the basis of dsdna replicative intermediates of bbtv. the strand-specific probes were not only able to detect the presence of the virus but also gave an indication of where the virus replicated. the results using both the virion sense and comple ... | 1995 | 7561765 |
