摘  要:
矢尖蚧(Unaspis yanonensis Kuwana)是柑桔上重要的害虫之一。据观察,在武汉地区,矢尖蚧以雌成蚧越冬,而第一龄幼蚧不能越冬;雌成蚧次年腹下幼蚧出现高峰期在5月13日,田间第一代第一龄幼蚧发生高峰期在5月23日,第二龄幼蚧发生高峰期则在6月9日。选用50%乐果乳剂1000倍+1/100机油乳剂或单用40倍机油乳剂,采取全株淋洗式喷雾方法,在4月上、中旬各喷药一次可有效地防治越冬雌成蚧的为害并降低当年幼蚧基数;继于5月底和6月中旬采用同样的农药和方法各喷药一次可制止第一代幼蚧的传播及为害,从而达到全年控制或消除矢尖蚧危害之目的。

摘  要:
Unaspis yanonensis Kuwana is one of the most important pests in citrus. The female adult can hibernate, the first stadium larva cannot hibernate. Under the conditions in Wuhan, the peak period for larvas to arise from the abdomen of the hibernating female adults in the field was May 13, the first stadium larvas appeared on May 23, and the second stadium larvas on June 9. The damage caused by hibernating female adults can be controlled by spraying the whole plant with 0.1% Rogor emulsion+1% machine-oil emulsion or 2.5% machine-oil emulsion, in early and middle April, respectively, such sprays also reduce the base number of larvas for the year. The spread and damage caused by the larvas of the first generation can be controlled by spraying the same pesticide in late May and mid June, respectively.
