美国加州拟用生物武器应对柑橘黄龙病

核心提示：据外媒报道，受柑橘黄龙病影响，美国佛罗里达州与洛杉矶的柑橘树遭重创，果农损失惨重。为应对来自亚洲的黄龙病，加州果农与加州州立大学波莫纳分校联手对抗黄龙病，利用亮腹釉小黄蜂（Tamarixia radiata wasp）这种生物武器进行应对。

加州州立理工大学波莫纳分校校长表示，柑橘黄龙病影响加州产值33亿美元的柑橘产业，世界其他地区的柑橘产业也大受影响。

　　据了解，黄龙病由木虱虫引发。橘子及柠檬等柑橘科的植物，如果感染黄龙病，叶子会枯黄，果肉变酸，最终果树会死亡。利用木虱虫的天敌-亮腹釉小黄蜂是一种较好的生物应对方法。

　　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.
