| 【目的】水稻普通矮缩病是一种常见的病毒性病害，对水稻生产造成了严重的威胁。水稻矮缩病毒（Rice
dwarf virus, RDV）是该病害的病原物，主要依赖黑尾叶蝉经卵以持久增殖方式传播。探明水稻矮缩病毒对介体昆虫
黑尾叶蝉的影响，可为黑尾叶蝉的种群治理和水稻普通矮缩病的可持续控制提供依据。【方法】设置健康与感病 2
个水稻处理，在室内 27 ℃条件下，观测黑尾叶蝉的生长发育、种群增长情况，组建实验种群生命表。【结果】介体
昆虫黑尾叶蝉在感染水稻矮缩病毒的水稻上取食后，若虫期存活率、成虫鲜重无显著差异，雌成虫寿命和产卵量略
有延长 / 增加，但雌雄虫若虫发育历期和雄成虫寿命显著缩短，种群数量显著增多，5 个生命表参数中净生殖率显著
提高。【结论】感染水稻矮缩病毒的水稻对介体黑尾叶蝉存在有利的间接影响，水稻矮缩病毒有利于黑尾叶蝉种群
的增长。 |

| 【Objective】Rice dwarf disease is a kind of common viral disease, which causes serious threats to rice
production. Rice dwarf virus (RDV) is the pathogeny and the spread of the disease is mainly rely on Nephotettix cincticeps
(Uhler) in a persistent-propagative manner. The exploration on the effects of RDV on the vector insect green rice leafhopper
can provide basis for the population control of N. cincticeps and the sustainable control of rice dwarf disease.【Method】Two
treatments(non-infected and RDV-infected) were set at 27℃ in laboratory, the growth and population increase of N.cincticeps
were observed and the life tables of experimental populations were constructed.【Result】The results showed that the nymph
survival, fresh body weight per male/female adult of N.cincticeps fed on RDV-infected rice plants did not significantly differ
from those on healthy plants, longevity and fecundity of female adult were slightly longer/higher, and the population number
of adults was significantly increased, whereas the growth period of male/female nymph and longevity of male adult was
decreased obviously. Also, the net reproductive rate (R0) significantly increased among the five life table parameters.
【Conclusion】RDV-infected rice plants has positive indirect effects on N.cincticeps and RDV is beneficial to the population increase of N.cincticeps |
