从10月份开始,柑橘生产进入采摘期,橘农忙于柑橘的采收工作。笔者近日下乡调查,发现一些地方橘园出现了黑刺粉虱,严重危害果实,果皮颜色变黑,外观受到影响,甚至一部分果实已失去商品价植,橘农望而兴叹。有的橘农已开展化学防治,但因该虫是一种具有地域性发生特点的柑橘害虫,并向周边扩散,一家一户单独防治收效甚微,因为未防治地区的黑刺粉虱很易再向其他橘园传入,因此虽一家积极防治,但因周边防治不力,同样遭致该虫的危害,劳而无功。因此,笔者认为应以村、组为单位统一时间、统一用药,这样才能收到群防群治的效果。 Since October, citrus production has entered the picking period and orange farmers are busy with citrus harvesting. The author recently went to the countryside to investigate and found that in some places Orangery had blackthorn whitefly, which seriously jeopardized the fruit. The color of the peel became dark and the appearance was affected. Even part of the fruit had lost its commodity price, and the orange farmer was disappointed. Some tangerines have already started chemical control. However, since the pest is a citrus pest with regional characteristics and spreads to the periphery, the single prevention and control of one family alone has little effect because the black striped whiteflies are not easily controlled And then pass to other orangery, so although a positive prevention and control, but due to the surrounding prevention and control, the same was the harm caused by the insects, labor and powerless. Therefore, I believe that should the village, group unit for a unified time, unified medication, so as to receive the effect of group prevention and treatment.
