1.三化螟全区第三代三化螟属中等偏轻、局部中等偏重程度发生,比上年同期重。由于第三代三化螟成虫盛发期长,发生量大,部分灾区灾后补播的秧田螟害率之高,部分稻区早插田着卵量之多、螟害率之高为近年罕见。发生的主要区域是桂中、桂南大部及桂东北的部分稻区。其中临桂、阳朔、柳江、富川、钟山、上林、天等、浦北等县将偏重发生。2.稻飞虱全区第五代稻飞虱为轻、局部中等偏轻程度发生。大部分稻区发生量接近上年,比常年偏少。另据全区农技中心通报的信息及湖北病虫情报:长江流域稻区田间稻飞虱数量均出现猛增势头,随着9～10月稻飞虱的回迁,我区晚稻后期稻飞虱虫源将增多。预计全区晚稻中后期稻飞虱为中等偏重、局部大发生程度发生,发生面积约650万亩。发生的主要区域是桂东北、桂东南的大部及桂中的部分稻区,其中桂林、贺州、梧州、玉林、贵港等地(市)的部分县(市)将大发生。3、稻纵卷叶螟全区第五代稻纵卷叶螟属轻、局部中等偏轻程度发生。大部分稻区发生量比上年、常年偏少。预计全区第六代稻纵卷叶螟为中等偏轻、局部中等偏重程度发生。发生面积300万亩。主要发生区域是桂东南、桂中、沿海稻区的大部及桂东北的部分稻区。
1. Third generation borer boreal third generation borer is moderately light, local moderate degree of emphasis, heavier than the same period last year. As the third generation of Borer borer adult Shengfa a long period, the occurrence of large, some post-disaster replantation post-disaster seedling pest rate is high, part of the early rice fields in the area as much as the amount of eggs, pest rate is rare in recent years . The main areas that occurred were Guizhong, Guinan, and part of the rice in northeast Guangxi. Among them, Lingui, Yangshuo, Liujiang, Bucheon, Zhongshan, Shanglin, Tianbei, Pubei and other counties will be preoccupied. 2. Planthopper The fifth generation of planthopper in the whole area is light, and local moderately mild degree occurs. The incidence of most rice areas is close to the previous year, less than usual. According to the information reported by the region’s agricultural technology center and the information of Hubei pests and diseases: the number of rice planthoppers in the Yangtze River Basin rice fields showed a surge in the number of rice planthoppers, with the transfer of planthoppers from September to October, Insect sources will increase. It is estimated that the late-season rice planthoppers in the whole area are moderately-biased and the occurrence of local large-scale occurrence takes place, with an area of about 6.5 million mu. The main areas that occurred were northeast Guangxi, southeast Guangxi and part of the rice in Guangxi. Some counties (cities) in Guilin, Hezhou, Wuzhou, Yulin, Guigang and other places will take place. Third, the fifth generation of rice leafroller boreal leafroller is light, partial moderate degree of occurrence. The incidence of most rice areas is less than that of the previous year and that of perennials. It is estimated that the sixth generation of rice leafroller in the whole region is moderately moderate and local moderately heavier. Occurred area of 300 mu. The main area is the southeastern Guangxi, Guangxi, coastal rice most of the area and part of the northeast Guangxi rice.
