據(jù)外媒報(bào)道,受柑橘黃龍病影響,美國(guó)佛羅里達(dá)州與洛杉磯的柑橘樹(shù)遭重創(chuàng),果農(nóng)損失慘重。為應(yīng)對(duì)來(lái)自亞洲的黃龍病,加州果農(nóng)與加州州立大學(xué)波莫納分校聯(lián)手對(duì)抗黃龍病,利用亮腹釉小黃蜂(Tamarixia radiata wasp)這種生物武器進(jìn)行應(yīng)對(duì)。
加州州立理工大學(xué)波莫納分校校長(zhǎng)表示,柑橘黃龍病影響加州產(chǎn)值33億美元的柑橘產(chǎn)業(yè),世界其他地區(qū)的柑橘產(chǎn)業(yè)也大受影響。
據(jù)了解,黃龍病由木虱蟲(chóng)引發(fā)。橘子及檸檬等柑橘科的植物,如果感染黃龍病,葉子會(huì)枯黃,果肉變酸,最終果樹(shù)會(huì)死亡。利用木虱蟲(chóng)的天敵-亮腹釉小黃蜂是一種較好的生物應(yīng)對(duì)方法。
部分原文報(bào)道如下:
Cal Poly Pomona is training an army of tiny wasps to battle the Asian citrus psyllid, a voracious pest responsible for crippling the Florida citrus industry that has recently infiltrated Los Angeles County.
Armed with a $400,000 grant from the Citrus Pest & Disease Prevention Program, the agriculture-oriented university unveiled a new research greenhouse Monday that may become the second-largest facility in Southern California (the largest is in Mt. Rubidoux) for breeding the Tamarixia radiata, a natural predator of the tree-killing psyllid.
The new flank in the war against the citrus plant disease Huanglongbing, carried by the pest, is part of a multi-pronged battle to reduce the infestation of psyllid in Los Angeles, Imperial, Ventura and Riverside counties, wher growers make up a portion of California's $3.3 billion citrus industry.
