稻(dao)(dao)飛(fei)虱：受“蓮(lian)花”、“浪卡”兩臺風的(de)影(ying)響(xiang)，我(wo)省(sheng)6月(yue)(yue)中下旬以來持續有稻(dao)(dao)飛(fei)虱遷入，大(da)部(bu)(bu)分(fen)縣(xian)(xian)日燈下稻(dao)(dao)飛(fei)虱80-200只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)達2880只(zhi)(zhi)(zhi)(zhi)(zhi)，萬(wan)安(an)(an)6月(yue)(yue)14-21日連續7天燈下稻(dao)(dao)飛(fei)虱超(chao)過1000只(zhi)(zhi)(zhi)(zhi)(zhi)，19日達2880只(zhi)(zhi)(zhi)(zhi)(zhi)；廣豐(feng)6月(yue)(yue)20-22日燈下稻(dao)(dao)飛(fei)虱分(fen)別為1280只(zhi)(zhi)(zhi)(zhi)(zhi)、2112只(zhi)(zhi)(zhi)(zhi)(zhi)、1600只(zhi)(zhi)(zhi)(zhi)(zhi)。上(shang)(shang)(shang)猶(you)、萬(wan)安(an)(an)、泰(tai)和(he)、吉水(shui)、永豐(feng)、宜(yi)豐(feng)、鉛山、上(shang)(shang)(shang)饒(rao)(rao)縣(xian)(xian)、資(zi)溪、萍(ping)鄉(xiang)市、蓮(lian)花、安(an)(an)義、余(yu)干、婺源、都昌、修(xiu)水(shui)等32個(ge)縣(xian)(xian)7月(yue)(yue)上(shang)(shang)(shang)旬調(diao)查，稻(dao)(dao)飛(fei)虱百叢(cong)蟲(chong)量(liang)一(yi)(yi)般(ban)為420-1800只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)為2000-9400只(zhi)(zhi)(zhi)(zhi)(zhi)，同比(bi)較(jiao)去年(nian)(nian)增(zeng)(zeng)加2倍，以白背飛(fei)虱若蟲(chong)和(he)卵為主。贛州西北部(bu)(bu)、吉安(an)(an)市大(da)部(bu)(bu)、撫州東(dong)南部(bu)(bu)、九江上(shang)(shang)(shang)饒(rao)(rao)東(dong)部(bu)(bu)蟲(chong)量(liang)高(gao)于去年(nian)(nian)同期（詳(xiang)見(jian)圖2），其中萬(wan)安(an)(an)縣(xian)(xian)一(yi)(yi)般(ban)900只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)16800只(zhi)(zhi)(zhi)(zhi)(zhi)，同比(bi)（較(jiao)去年(nian)(nian)（下同））增(zeng)(zeng)加3倍；泰(tai)和(he)縣(xian)(xian)一(yi)(yi)般(ban)650只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)1650只(zhi)(zhi)(zhi)(zhi)(zhi)，同比(bi)增(zeng)(zeng)加3-5倍；宜(yi)豐(feng)縣(xian)(xian)一(yi)(yi)般(ban)2400只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)9400只(zhi)(zhi)(zhi)(zhi)(zhi)，同比(bi)增(zeng)(zeng)加4倍；鉛山縣(xian)(xian)一(yi)(yi)般(ban)350只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)1600只(zhi)(zhi)(zhi)(zhi)(zhi)，同比(bi)增(zeng)(zeng)加2-3倍；余(yu)干縣(xian)(xian)一(yi)(yi)般(ban)400只(zhi)(zhi)(zhi)(zhi)(zhi)，高(gao)的(de)700只(zhi)(zhi)(zhi)(zhi)(zhi)，同比(bi)增(zeng)(zeng)加2-3倍（詳(xiang)見(jian)圖1）。
各地要加強監(jian)測，因地制宜搞好分(fen)類指導(dao)，當前要以稻(dao)瘟(wen)病(bing)(bing)(bing)(bing)、稻(dao)飛虱為主，抓好中稻(dao)的病(bing)(bing)(bing)(bing)蟲(chong)防(fang)治工作，對出現(xian)稻(dao)葉瘟(wen)發病(bing)(bing)(bing)(bing)中心或急(ji)性型病(bing)(bing)(bing)(bing)斑的中稻(dao)田要立(li)即(ji)施藥防(fang)治，藥劑(ji)(ji)可選用(yong)稻(dao)瘟(wen)靈或三(san)環唑或春雷霉素等，同時加入噻嗪酮(tong)或吡蚜(ya)酮(tong)或噻蟲(chong)嗪和井岡霉素等藥劑(ji)(ji)預(yu)防(fang)稻(dao)飛虱、紋枯病(bing)(bing)(bing)(bing)。
另外，受淹稻(dao)田要加強白葉(xie)枯(ku)病(bing)、細(xi)菌性(xing)(xing)(xing)基腐病(bing)和(he)細(xi)菌性(xing)(xing)(xing)條(tiao)斑病(bing)的預防，可(ke)選用農克菌膠懸劑(ji)，氯溴(xiu)異(yi)氰尿酸可(ke)溶(rong)性(xing)(xing)(xing)粉劑(ji)或葉(xie)青雙(shuang)可(ke)濕性(xing)(xing)(xing)粉劑(ji)進(jin)行預防。(江西省植保植檢局)
