近日,云南省植保站根据今年该省气候特点和水稻生长情况,对稻飞虱发生进行动态预报,稻飞虱发生程度略低于去年。据了解近期该省文山、红河、思茅、临沧、版纳、保山等6个州、市稻区出现明显的稻飞虱迁入峰。水稻秧田和大田不同程度受害。从目前发生情况分析,发生虫种以白背飞虱为主。占总虫口数量的94.3%,褐飞虱仅占5.7%。在隆阳区、施甸县、姚安县等地,灰飞虱发生也比较严重,将导致水稻条纹叶枯病重发生。目前,全省一季中稻正处于分蘖期,稻飞虱将进一步向外迁飞扩散。预计全省中等偏重发生,发生程度略低于2003年。
Recently, Yunnan Plant Protection Station according to the province’s climate characteristics and rice growth this year, the dynamics of planthopper occurred, the occurrence of planthopper was slightly lower than last year. It is understood that the recent Wenshan, Honghe, Simao, Lincang, Banna, Baoshan and other six states, the city appeared obvious rice planthoppers moved into the peak. Rice seedlings and fields suffer to varying degrees. From the current situation analysis, the occurrence of white-backed planthopper-based. 94.3% of the total number of insect population, brown planthopper only 5.7%. In Longyang District, Shidian County, Yao County and other places, Laodelphax striatellus is also more serious, will lead to the occurrence of rice stripe leaf blight. At present, the province’s rice season in mid-season is at a tillering stage, and planthopper will further fly away and disperse. The province is expected to be moderately moderate, with the incidence slightly lower than in 2003.
