使用室外杀虫(chong)灯的好处？

首先，杀(sha)(sha)伤天(tian)(tian)敌(di), 影响生(sheng)(sheng)态(tai)平(ping)衡；在(zai)(zai)使(shi)用(yong)(yong)太(tai)阳(yang)能(neng)杀(sha)(sha)虫(chong)(chong)(chong)灯(deng)进(jin)行(xing)害虫(chong)(chong)(chong)测报时(shi)(shi), 也能(neng)同(tong)时(shi)(shi)预(yu)测当地(di)(di)优势种天(tian)(tian)敌(di)的(de)发(fa)生(sheng)(sheng)期(qi)与发(fa)生(sheng)(sheng)量, 有效地(di)(di)指导农(nong)民点(dian)(dian)灯(deng)与用(yong)(yong)药,限度地(di)(di)减少天(tian)(tian)敌(di)杀(sha)(sha)伤。杀(sha)(sha)虫(chong)(chong)(chong)灯(deng)在(zai)(zai)诱杀(sha)(sha)害虫(chong)(chong)(chong)的(de)同(tong)时(shi)(shi), 对(dui)天(tian)(tian)敌(di)也具(ju)有较强的(de)杀(sha)(sha)伤能(neng)力, 建议(yi)在(zai)(zai)自然生(sheng)(sheng)态(tai)条件(jian)好的(de)地(di)(di)区(qu)不要(yao)使(shi)用(yong)(yong)太(tai)阳(yang)能(neng)杀(sha)(sha)虫(chong)(chong)(chong)灯(deng), 在(zai)(zai)适(shi)合使(shi)用(yong)(yong)的(de)地(di)(di)区(qu)应(ying)该事先做好害虫(chong)(chong)(chong)监测, 应(ying)在(zai)(zai)防治适(shi)期(qi)使(shi)用(yong)(yong)。今后杀(sha)(sha)虫(chong)(chong)(chong)灯(deng)的(de)研究(jiu)应(ying)以保护正(zheng)常(chang)的(de)生(sheng)(sheng)物链、稳定的(de)生(sheng)(sheng)态(tai)环境作为研究(jiu)重点(dian)(dian)。针对(dui)昆虫(chong)(chong)(chong)时(shi)(shi)段活动习性开展(zhan)技术(shu)研究(jiu), 将害虫(chong)(chong)(chong)在(zai)(zai)一定区(qu)域内有选择(ze)的(de)诱杀(sha)(sha), 应(ying)注(zhu)意科学(xue)用(yong)(yong)灯(deng), 减少对(dui)天(tian)(tian)敌(di)的(de)伤害。

其(qi)(qi)次，只(zhi)能是(shi)药(yao)(yao)剂防(fang)治(zhi)的(de)辅助手段；昆虫(chong)的(de)趋光(guang)(guang)(guang)性不同, 有(you)的(de)害(hai)虫(chong)根(gen)本没有(you)趋光(guang)(guang)(guang)性或只(zhi)对单一波(bo)长的(de)光(guang)(guang)(guang)具有(you)趋光(guang)(guang)(guang)性。因此, 使(shi)用诱(you)(you)(you)虫(chong)灯(deng)测报或诱(you)(you)(you)杀害(hai)虫(chong)时, 应视具体情况结合(he)(he)性诱(you)(you)(you)剂、糖醋液、黄(huang)板诱(you)(you)(you)杀等(deng)其(qi)(qi)他(ta)物理防(fang)治(zhi)方法, 才能获(huo)得较好的(de)效果。灯(deng)光(guang)(guang)(guang)诱(you)(you)(you)杀只(zhi)是(shi)化学(xue)防(fang)治(zhi)的(de)有(you)效补(bu)充(chong), 可降低生(sheng)产成本, 延(yan)缓害(hai)虫(chong)产生(sheng)抗药(yao)(yao)性。频振式杀虫(chong)灯(deng)能降低水稻害(hai)虫(chong)的(de)密度, 减少了施药(yao)(yao)次数, 但并不能完全代替农(nong)药(yao)(yao)防(fang)治(zhi),须与农(nong)药(yao)(yao)、生(sheng)物、农(nong)艺等(deng)防(fang)治(zhi)措施相结合(he)(he)。

科学(xue)使(shi)(shi)用太阳能杀(sha)(sha)(sha)虫(chong)灯(deng)；生产上使(shi)(shi)用杀(sha)(sha)(sha)虫(chong)灯(deng)时往(wang)往(wang)存在测(ce)报不(bu)准确和(he)诱杀(sha)(sha)(sha)效(xiao)果不(bu)理想等问题, 这些往(wang)往(wang)是由于(yu)杀(sha)(sha)(sha)虫(chong)灯(deng)使(shi)(shi)用不(bu)科学(xue)造成(cheng)的(de)。杀(sha)(sha)(sha)虫(chong)灯(deng)用于(yu)测(ce)报和(he)防(fang)治时的(de)设灯(deng)密度不(bu)同, 应根(gen)据(ju)不(bu)同情况合理布置, 否(fou)则难以达到(dao)较好的(de)效(xiao)果。
