“…The fact that young suckers produce a new leaf approximately every 5 d ) would suggest that Provado would only provide short-term protection from aphids found on plants that are not mature. As an alternative to targeting every banana mat during a spraying session, Hooks et al (2009a) proposed that farmers seek out and treat only BBTV infected mats and neighboring plants. The tentative hypothesis is that if Þelds are regularly scouted for BBTV-infected plants and upon detection, infected and neighboring mats are timely sprayed with an insecticide and treated with a bananacide (i.e., herbicide register for destroying infected banana plants), this strategy would reduce spray amounts and associated production cost signiÞcantly, allow users to be in compliance with spray amount restrictions, and would reduce BBTV spread compared with treating the entire Þeld or restricting sprays to small and medium sized suckers.…”

“…Recently, there have been several studies and outreach efforts conducted in Hawaii aimed at learning more about the biology and ecology of P. nigronervosa and the epidemiology of BBTV (Young and Wright 2005;Anhalt and Almeida 2008;Hooks et al 2008Hooks et al , 2009a and developing and disseminating an integrated disease management program for BBTV (Perez and Hooks 2008). Current tactics recommended for mitigating BBTV spread in Hawaii include 1) timely identiÞcation and destruction of virus-infected plants, 2) insecticidal treatment of virus-infected plants before roguing, 3) replanting only with known virus-free tissue cultured plants, and 4) controlling P. nigronervosa populations.…”

“…The Banana Bunchy Top Virus (BBTV; Genus Babuvirus; Family Nanoviridae) is one of the major destructive viruses causing limited production in banana [26]. It is a positive sense (+) circular single-stranded (ss) multipartite DNA virus with six genome components of 1.1 kb each [27,28].…”

Effect of Banana Bunchy Top Virus on the Heat Shock Protein Genes of Pentalonia nigronervosa during Temperature Susceptibility and Its Effect on Virus Transmission

et al. 2021

Acquisition of plant viruses is known to exert various effects on vectors’ developmental biology. Pentalonia nigronervosa is the only known vector of banana bunchy top virus (BBTV), which is an economically detrimental virus infecting banana cultivars all over the world. In the present study, the developmental biology of viruliferous (Vr) and non-viruliferous (NVr) aphids was compared, with a marked reduction noted in the lifespan of aphids upon acquisition of BBTV. Among all the environmental parameters temperature is an important determinant of an insect’s abundance and geographical distribution. Temperature susceptibility of P. nigronervosa was scrutinized by comparing the mortality percentage and differential expression pattern of three heat shock proteins (Hsps; Hsp40, Hsp70, and Hsp90) at the mRNA level between NVr and Vr aphids. After exposure to different temperature stress (5 °C, 15 °C, 38 °C and 25 °C as control) highest mortality of Vr aphids were recorded at 5 °C. Analysis of expression levels of Hsp genes using qPCR showed that both cold and heat shock treatment stimulated higher expression of the three Hsps at various rates in Vr than NVr aphids.. Finally, the effect of temperature stress on the BBTV titer level and their transmission by P.nigronervosa was determined by absolute quantification. The transmission efficiency along with the virus titer was found to be the lowest at 15 °C compared to 38 °C. Overall, our results provide a novel insight into the intricate interaction between aphid fitness and thermal stress concerning the acquisition and transmission of BBTV, which could be a roadmap for the future epidemiological control system.

“…The speculative effects of herbicide application on the invasion of viruses can be divided into the following: plants were not affected by herbicide; plants were affected by the herbicide, the virus concentration was suppressed, enhanced or not affected (Kazinczi et al, 2003). Previous investigations has generally showed that the activity of viruses are inhibited by the application of herbicides (Kazinczi et al, 2006; Hooks et al, 2009). Krcatovic et al (2008) point out that the treatment of some metabolites such as flavonoids, quercetin, and vitexin on plants also can only suppress the activity of TMV during early infection accompanied with the induce of SA, but the phenomenon cannot last for a long time.…”

Bensulfuron-methyl (BSM) is widely used in paddy soil for weed control. BSM residue in the soil has been known to inhibit the growth of sensitive crop plants. However, it is unknown whether BSM residue can affect the agrosystem in general. In this study, we have found significant effects of BSM on the infestation of Bemisia tabaci, Myzus persicae, and Tobacco mosaic virus (TMV) in Nicotiana tabacum. The soil was treated with BSM before the pest inoculation. The herbicide-treated tobaccos showed resistance to B. tabaci, but this resistance could not be detected until 15-day post-infestation when smaller number of adults B. tabaci appeared. In M. persicae assay, the longevity of all development stages of insects, and the fecundity of insects were not significantly affected when feeding on BSM-treated plants. In TMV assay, the BSM treatment also reduced virus-induced lesions in early infection time. However, the titer of TMV in BSM treated plants increased greatly over time and was over 40-fold higher than the mock-infected control plants after 20 days. Further studies showed that BSM treatment increased both jasmonic acid (JA) and salicylic acid (SA) levels in tobacco, as well as the expression of target genes in the JA and SA signaling pathways, such as NtWIPK, NtPR1a, and NtPAL. NtPR1a and NtPAL were initially suppressed after virus-inoculation, while NtRDR1 and NtRDR6, which play a key role in fighting virus infection, only showed up- or were down-regulated 20 days post virus-inoculation. Taken together, our results suggested that BSM residue in the soil may affect the metabolism of important phytohormones such as JA and SA in sensitive plants and consequently affect the plant immune response against infections such as whitefly, aphids, and viruses.
