棗(zao)樹(shu)(shu)(shu)(shu)紅(hong)(hong)(hong)蜘(zhi)蛛(zhu)不僅危害(hai)(hai)(hai)(hai)棗(zao)樹(shu)(shu)(shu)(shu)，同時(shi)(shi)還會(hui)危害(hai)(hai)(hai)(hai)棉花(hua)、豆類、茄子等大(da)田作物和(he)桑樹(shu)(shu)(shu)(shu)、桃樹(shu)(shu)(shu)(shu)等樹(shu)(shu)(shu)(shu)木。棗(zao)樹(shu)(shu)(shu)(shu)紅(hong)(hong)(hong)蜘(zhi)蛛(zhu)以成螨(man)、幼螨(man)和(he)若螨(man)集中(zhong)在葉(xie)(xie)芽(ya)和(he)葉(xie)(xie)片(pian)上取(qu)食汁液為(wei)害(hai)(hai)(hai)(hai)，被害(hai)(hai)(hai)(hai)植株初期葉(xie)(xie)片(pian)出現失綠的(de)小(xiao)斑點，后(hou)逐(zhu)漸擴大(da)成片(pian)，嚴重時(shi)(shi)棗(zao)樹(shu)(shu)(shu)(shu)的(de)葉(xie)(xie)片(pian)呈枯黃(huang)色，提(ti)前落葉(xie)(xie)、落果(guo)，引起大(da)量減產和(he)果(guo)實品質下(xia)降。棗(zao)樹(shu)(shu)(shu)(shu)紅(hong)(hong)(hong)蜘(zhi)蛛(zhu)以雌(ci)成螨(man)和(he)若螨(man)在樹(shu)(shu)(shu)(shu)皮裂縫、雜(za)草根際和(he)土縫隙中(zhong)越冬(dong)。在來年環境條件(jian)適宜時(shi)(shi)，更有利(li)于(yu)紅(hong)(hong)(hong)蜘(zhi)蛛(zhu)蟲害(hai)(hai)(hai)(hai)的(de)發生(sheng)(sheng)，棗(zao)樹(shu)(shu)(shu)(shu)萌芽(ya)時(shi)(shi)出蟄為(wei)害(hai)(hai)(hai)(hai)活動。棗(zao)樹(shu)(shu)(shu)(shu)紅(hong)(hong)(hong)蜘(zhi)蛛(zhu)發生(sheng)(sheng)高(gao)(gao)峰(feng)期，高(gao)(gao)溫、干(gan)旱和(he)刮風利(li)于(yu)該(gai)蟲的(de)發生(sheng)(sheng)和(he)傳播。棗(zao)樹(shu)(shu)(shu)(shu)紅(hong)(hong)(hong)蜘(zhi)蛛(zhu)一(yi)般在高(gao)(gao)溫干(gan)旱的(de)氣(qi)候條件(jian)下(xia)，繁殖迅速，為(wei)害(hai)(hai)(hai)(hai)棗(zao)樹(shu)(shu)(shu)(shu)較為(wei)嚴重。

為了及(ji)(ji)時(shi)(shi)的防治(zhi)(zhi)棗(zao)(zao)樹(shu)(shu)紅(hong)蜘(zhi)蛛，園(yuan)林(lin)人(ren)員應(ying)及(ji)(ji)時(shi)(shi)采取(qu)有效(xiao)的措施防治(zhi)(zhi)棗(zao)(zao)樹(shu)(shu)紅(hong)蜘(zhi)蛛。園(yuan)林(lin)人(ren)員在(zai)冬春季刮(gua)樹(shu)(shu)皮、鏟(chan)除(chu)雜草、清除(chu)落(luo)葉，并(bing)及(ji)(ji)時(shi)(shi)清除(chu)進行銷(xiao)毀，消滅越(yue)冬雌蟲(chong)和若(ruo)蟲(chong)。棗(zao)(zao)樹(shu)(shu)在(zai)發芽前(qian)棗(zao)(zao)樹(shu)(shu)應(ying)及(ji)(ji)時(shi)(shi)噴灑(sa)3-50倍(bei)(bei)(bei)液石硫合劑、或(huo)200倍(bei)(bei)(bei)阿維(wei)柴(chai)油(you)乳(ru)(ru)劑，最大限度地(di)消滅越(yue)冬蟲(chong)原的發生。棗(zao)(zao)樹(shu)(shu)紅(hong)蜘(zhi)蛛在(zai)若(ruo)螨發生盛期(qi)，及(ji)(ji)時(shi)(shi)對棗(zao)(zao)樹(shu)(shu)冠細致噴灑(sa)3000倍(bei)(bei)(bei)2%阿維(wei)菌(jun)素液、或(huo)2000倍(bei)(bei)(bei)20%噠螨靈乳(ru)(ru)油(you)液、或(huo)2000倍(bei)(bei)(bei)28.3%噻螨。特乳(ru)(ru)油(you)液、或(huo)1000倍(bei)(bei)(bei)10%瀏陽霉素乳(ru)(ru)油(you)液、或(huo)1000-1500倍(bei)(bei)(bei)25%三唑錫(xi)可濕性粉劑液1-2次(ci)。噴灑(sa)以上藥劑時(shi)(shi)，注意摻加1000倍(bei)(bei)(bei)果樹(shu)(shu)專(zhuan)用型(xing)“天(tian)達2116”，每(mei)隔15天(tian)1次(ci)，可顯著提高棗(zao)(zao)樹(shu)(shu)的防治(zhi)(zhi)效(xiao)果，并(bing)能增強棗(zao)(zao)樹(shu)(shu)植株(zhu)抗病、抗干(gan)旱等抗逆性能，防治(zhi)(zhi)棗(zao)(zao)樹(shu)(shu)紅(hong)蜘(zhi)蛛效(xiao)果極為顯著。
