據全國農技中心組織專家會商分析，預計(ji)2023年全(quan)(quan)國農(nong)(nong)區(qu)(qu)鼠害總(zong)體呈(cheng)中等發生（3級(ji)），局部呈(cheng)偏(pian)重(zhong)發生（4級(ji)）趨勢。其中，中部大部分(fen)地區(qu)(qu)呈(cheng)偏(pian)輕至中等發生（2-3級(ji)）、局部偏(pian)重(zhong)發生（4級(ji)）。預計(ji)全(quan)(quan)國農(nong)(nong)田(tian)(tian)鼠害發生面(mian)積約3.33億畝，比2022年增加(jia)907萬(wan)畝，重(zhong)發面(mian)積約0.33億畝。農(nong)(nong)舍鼠害發生約0.88億戶(hu)，較2022年增加(jia)20萬(wan)戶(hu)。農(nong)(nong)區(qu)(qu)鼠害總(zong)體處于種(zhong)(zhong)群數量恢復期(qi)，田(tian)(tian)間鼠密度相對穩定，農(nong)(nong)林、農(nong)(nong)牧(mu)交錯(cuo)地帶，湖區(qu)(qu)、庫區(qu)(qu)和沿江(jiang)（河）流域(yu)，山區(qu)(qu)（半山區(qu)(qu)）以及種(zhong)(zhong)植(zhi)業(ye)結構(gou)調(diao)整區(qu)(qu)、南繁(fan)育種(zhong)(zhong)基地等農(nong)(nong)區(qu)(qu)鼠害有偏(pian)重(zhong)發生態(tai)勢。特別是種(zhong)(zhong)植(zhi)業(ye)調(diao)整地區(qu)(qu)農(nong)(nong)田(tian)(tian)優勢鼠種(zhong)(zhong)發生演替、發生范圍廣(guang)，高密度種(zhong)(zhong)群點(dian)片發生，局部地區(qu)(qu)危(wei)害損(sun)失(shi)可能加(jia)重(zhong)，需密切(qie)關注。
