“…Banana bunchy top disease (BBTD) only affects plants in the family Musaceae where it causes serious losses in banana ( Musa spp.) in the Pacific, South and South-east Asia, India and sub-Saharan Africa (Kagy et al , 2001; Kumar et al , 2011; Thomas et al , 2000). Infection causes plant stunting, leaf bunching and severely impaired fruit development.…”

Banana bunchy top virus (BBTV; family Nanoviridae, genus Babuvirus) is a multi-component, ssDNA virus, which causes widespread banana crop losses throughout tropical Africa and Australasia. We determined the full genome sequences of 12 BBTV isolates from the Kingdom of Tonga and analysed these together with previously determined BBTV sequences to show that reassortment and both inter-and intra-component recombination have all been relatively frequent occurrences during BBTV evolution. We found that whereas DNA-U3 components display evidence of complex inter-and intra-component recombination, all of the South Pacific DNA-R components have a common intra-component recombinant origin spanning the replicationassociated protein gene. Altogether, the DNA-U3 and DNA-M components display a greater degree of inter-component recombination than the DNA-R, -S, -C and -M components. The breakpoint distribution of the inter-component recombination events reveals a primary recombination hotspot around the 59 side of the common region major and, in accordance with recombination hotspots detectable in related ssDNA viruses, a secondary recombination hotspot near the origin of virion-strand replication.

“…This sad example illustrates the high importance of sound quarantine policy regarding allowance of plants that might arbor viruses that are absent, when a potential vector already is present. The importance of this species in New Caledonia dramatically increased in 2001 with the discovery of BBTV (Kagy et al 2001). It also is able to transmit Banana mosaic, Abaca bunchy top, and Cardamom mosaic viruses.…”

“…It was identified formally in 1991 in the Pocquereux Fruit Research Station (Mille 2000). Prior to 1999, the date of the discovery of the BBTV in New Caledonia (Kagy et al 2001), P. nigronervosa was not significant to banana crops, but then it became an important pest, as it was partly responsible of the spread of the BBTV throughout the country.

Thirty-three species of aphids are now established in New Caledonia. All species appear to have been introduced accidentally by human activity in the last century. Here, 17 aphid species are recorded for the first time: Aphis eugeniae, Aphis glycines, Aphis odinae, Aulacorthum solani, Brachycaudus helichrysi, Cerataphis orchidearum, Greenidea psidii, Hyperomyzus carduellinus, Hysteroneura setariae, Lipaphis pseudobrassicae, Micromyzus katoi, Myzus ornatus, Pentalonia caladii, Rhopalosiphum nymphaeae, Rhopalosiphum rufiabdominale, Schizaphis rotundiventris, and Tetraneura fusiformis. Thirteen more species are also more or less regularly intercepted at the borders through biosecurity surveys, without further establishment. This demonstrates that aphids represent a major biosecurity threat, including a threat as potential plant virus vectors. The reinforcement of biosecurity is a priority for such biodiversity hotspots, from the perspectives of both agriculture and the native environment. Prioritisation and promotion of local development of vegetable and fruit production, rather than their risky importation from abroad, is desirable. Such an approach also should be promoted and extended to other Pacific islands, which all share the lack of native aphid fauna and their associated plant disease vector risks.

“…The disease is caused by banana bunchy top virus (BBTV, genus Babuvirus) and transmitted by banana aphids (Pentalonia nigronervosa) and the transboundary exchange of infected planting materials. BBTD was first reported in the 1880s in Fiji (Magee, 1927) and has since been spreading to other banana producing countries in the world including several African countries, Oceania, Asia, and South Pacific (Figure 1; Adegbola, Ayodeji, Awosusi, Atiri, & Kumar, 2013;Jooste, Wessels, & Van der Merwe, 2016;Kagy, Thomas, Sharman, & Mademba-Sy, 2001; Kenyon, Brown, & Khonje, 1997;Khalid & Soomro, 1993;Kumar et al, 2011;Lokossou et al, 2012;Oben et al, 2009;Xie & Hu, 1995). In Africa, BBTD has spread to 17 different countries, and neighboring banana producing countries are at a high risk of being affected (Adegbola et al, 2013;Blomme et al, 2013;Jooste et al, 2016).…”
