摘要

2018年雨季(6月至10月),在尼日利亚卡杜纳州的三个主要生姜生产地方政府区(LGA)进行了一项实地调查,以确定感染生姜的小麦条纹花叶病毒(WSMV)的发生和传播情况。从调查的田地中收集有症状和无症状的生姜叶样本(n=180)和杂草样本(n=45),并使用双抗体夹心酶联免疫吸附测定法(DAS-ELISA)对WSMV进行索引。结果表明,WSMV在所有调查的LGA中都有发生,但分布差异显著(P=0.05)。Jaba的病毒发病率最高(22.67%),其次是Kagarko(17.67%),而Kachia的病毒感染率最低,为10.00%。据我们所知,这是尼日利亚首次报道WSMV感染生姜。Rottboellia cochinchinensis(Lour.)Clayton和Setaria barbata(Lam.)Kunth对WSMV的检测呈阳性,WSMV是病毒的替代杂草宿主。WSMV的发病率即使在较低的百分比下也是显著的,因为人口的增加可能导致疾病的爆发。需要为农民组织关于WSMV对生姜作物产量损失的可能性以及文化习俗在病毒发生和管理中的作用的宣传计划。

Occurrence, distribution and alternative hosts of Wheat streak mosaic virus infecting ginger in Kaduna State, Nigeria.
A field survey was conducted during the 2018 rainy season (June – October) in three major ginger producing Local Government Areas (LGAs) of Kaduna State, Nigeria to determine the occurrence and spread of wheat streak mosaic virus (WSMV) infecting ginger. Symptomatic and asymptomatic ginger leaf samples (n=180) and weed samples (n=45) were collected from the surveyed fields and indexed against WSMV using Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA). The results obtained showed that WSMV occurred in all the LGAs surveyed but with significant ( P = 0.05 ) variation in distribution. Jaba had the highest virus incidence (22.67\,\%) followed by Kagarko (17.67\,\%) while Kachia had the lowest virus incidence of 10.00\,\%. To the best of our knowledge, this is the first report of WSMV infecting ginger in Nigeria. Rottboellia cochinchinensis (Lour.) Clayton and Setaria barbata (Lam.) Kunth tested positive against WSMV as alternative weed hosts of the virus. The incidence of WSMV even at lower percentage is significant as population build-up could lead to a disease outbreak. Awareness programs need to be organised for farmers on yield loss potential of WSMV on ginger crop and the role of cultural practices on the incidence and management of the virus.
