近日，一種名為“松毛蟲赤眼蜂·松毛蟲質型多角體病毒殺蟲卡”的生物農藥，獲得了(le)農業部農藥(yao)檢定所的(de)審定和登記(ji)，這是首個獲得國(guo)家登記(ji)的(de)天(tian)敵生物(wu)農藥(yao)產品(pin)。據農藥(yao)檢定所相(xiang)關負責(ze)人(ren)介紹(shao)，在(zai)國(guo)外(wai)，赤(chi)眼蜂和病毒(du)(du)都(dou)是作為單一產品(pin)進行了(le)登記(ji)。國(guo)內已有松(song)毛蟲(chong)質型多角體病毒(du)(du)產品(pin)登記(ji)，尚無(wu)松(song)毛蟲(chong)赤(chi)眼蜂產品(pin)登記(ji)。
據介紹，“松(song)質(zhi)·赤(chi)眼(yan)蜂(feng)(feng)”殺蟲(chong)(chong)(chong)卡是(shi)由(you)中(zhong)科院(yuan)武漢病(bing)(bing)毒所結(jie)合(he)多(duo)年利用(yong)(yong)病(bing)(bing)毒治蟲(chong)(chong)(chong)的(de)經驗發(fa)明(ming)的(de)。它(ta)是(shi)利用(yong)(yong)“卵(luan)寄(ji)(ji)生蜂(feng)(feng)傳遞病(bing)(bing)毒防治害蟲(chong)(chong)(chong)”方(fang)法，將(jiang)松(song)毛(mao)(mao)(mao)蟲(chong)(chong)(chong)赤(chi)眼(yan)蜂(feng)(feng)和松(song)毛(mao)(mao)(mao)蟲(chong)(chong)(chong)質(zhi)多(duo)角(jiao)體病(bing)(bing)毒結(jie)合(he)，使初孵幼(you)蟲(chong)(chong)(chong)染病(bing)(bing)，在害蟲(chong)(chong)(chong)種(zhong)群(qun)內誘發(fa)流行病(bing)(bing)，達到控制害蟲(chong)(chong)(chong)的(de)目的(de)。具體加工工藝為:利用(yong)(yong)柞蠶卵(luan)作(zuo)為松(song)毛(mao)(mao)(mao)蟲(chong)(chong)(chong)赤(chi)眼(yan)蜂(feng)(feng)的(de)替代宿主繁(fan)育赤(chi)眼(yan)蜂(feng)(feng)，將(jiang)已寄(ji)(ji)生松(song)毛(mao)(mao)(mao)蟲(chong)(chong)(chong)赤(chi)眼(yan)蜂(feng)(feng)的(de)柞蠶卵(luan)制作(zuo)成卵(luan)卡,應(ying)用(yong)(yong)超(chao)低容量噴(pen)霧設(she)備(bei)將(jiang)松(song)毛(mao)(mao)(mao)蟲(chong)(chong)(chong)質(zhi)多(duo)角(jiao)體病(bing)(bing)毒均勻噴(pen)灑在卵(luan)卡表面。在松(song)毛(mao)(mao)(mao)蟲(chong)(chong)(chong)成蟲(chong)(chong)(chong)羽化(hua)高峰期，直接(jie)將(jiang)松(song)質(zhi)·赤(chi)眼(yan)蜂(feng)(feng)殺蟲(chong)(chong)(chong)卡，按5~7枚/畝掛在樹枝上(shang)即可。該(gai)殺蟲(chong)(chong)(chong)卡結(jie)合(he)赤(chi)眼(yan)蜂(feng)(feng)和病(bing)(bing)毒的(de)雙重(zhong)優點(dian)，通過(guo)赤(chi)眼(yan)蜂(feng)(feng)將(jiang)病(bing)(bing)毒帶入靶標，使初孵幼(you)蟲(chong)(chong)(chong)罹(li)病(bing)(bing)，導致二次感(gan)染，誘發(fa)病(bing)(bing)毒流行病(bing)(bing)，有(you)效(xiao)控制害蟲(chong)(chong)(chong)。
據悉，該產品目前在(zai)咸寧高(gao)新技術開發區進(jin)(jin)行(xing)批量生產，產品實現了零(ling)污(wu)染、零(ling)排放，一(yi)次用藥(yao)，多年受益(yi)(yi)，尤其對(dui)茶葉、蔬(shu)菜、水(shui)果等(deng)經濟作物(wu)具有(you)顯著的增(zeng)值效(xiao)益(yi)(yi)。目前日生產能(neng)力達7500畝，已在(zai)四川(chuan)、浙江、云南(nan)、湖(hu)北(bei)、河南(nan)、廣東、新疆等(deng)地進(jin)(jin)行(xing)示范60余萬(wan)畝。防(fang)治松毛蟲(chong)效(xiao)果達40%~70%左右，與對(dui)照藥(yao)劑Bt相比，防(fang)效(xiao)相當。
